Orbital Surgery

Introduction

If your doctor has spoken to you about orbital surgery, you are likely working through a mix of questions: what exactly will be operated on, how close the surgery comes to the eye itself, whether your vision is at risk, and what life will look like afterwards. This guide is written for patients who already have a diagnosis — such as thyroid eye disease, an orbital fracture, an orbital tumour, or another condition affecting the eye socket — and are now preparing for the next step.

Orbital surgery is a specialised area of eye surgery performed inside or around the bony cavity that holds the eye. It is usually carried out by an oculoplastic and orbital surgeon — an ophthalmologist who has completed additional training in eyelid, tear-drainage, and orbital procedures. The procedure your surgeon plans will depend entirely on what is causing the problem, where it sits inside the orbit, and what needs to be achieved — protecting vision, removing a growth, repairing broken bone, relieving pressure, or restoring appearance.

This article explains what orbital surgery involves, the main types of operations, how candidacy is decided, what happens on the day, recovery, risks, and what to expect in the months that follow.

What Is Orbital Surgery?

The orbit is the bony socket in your skull that holds and protects the eyeball. It is shaped roughly like a four-sided pyramid, with the wide opening at the front (where the eye sits) and the narrow tip pointing back towards the brain. Inside this small space lie:

• The eyeball (globe)
• The optic nerve, which carries visual information from the eye to the brain
• Six extraocular muscles that move the eye
• The lacrimal gland, which produces tears
• Fat, blood vessels and nerves that cushion and supply these structures

Because the orbit is densely packed and bordered by the sinuses, the brain, and the face, any disease process inside it — a tumour, swelling, fracture, infection, or excess tissue — can quickly affect vision, eye movement, or appearance. Orbital surgery is the family of operations that work within this space to address those problems.

Importantly, orbital surgery is not a single operation. It is a category that includes several very different procedures — from removing a small tumour through a hidden eyelid incision to removing parts of the orbital bone to relieve pressure. What links them is the location and the level of precision required.

Why Is Orbital Surgery Performed?

Orbital surgery is considered when a condition inside the eye socket cannot be safely managed with medication alone, or when it is causing — or is likely to cause — loss of vision, eye-movement problems, pain, or significant changes to appearance. The most common reasons include:

Thyroid Eye Disease (Graves’ Orbitopathy)

In thyroid eye disease, the tissues behind the eye become inflamed and swollen as part of an autoimmune process linked to thyroid problems. The eyes may bulge forward (proptosis), the eyelids may not close fully, and in severe cases the optic nerve can be compressed. Surgery — typically orbital decompression — is used to create more space inside the orbit when medical treatment is not enough.

Orbital Tumours

Growths inside the orbit can be benign (such as cavernous haemangiomas or dermoid cysts) or malignant (such as lymphomas or, less commonly, cancers spreading from elsewhere). Surgery may be done to remove the tumour, obtain a biopsy, or relieve pressure on nearby structures.

Orbital Fractures

The thin bones of the orbital floor and inner wall can break when the face takes a direct blow — from a fall, sports injury, road accident, or assault. If muscle or tissue becomes trapped in the fracture, or if the eye sinks into the broken socket, surgical repair may be needed.

Orbital Infections

Severe orbital infections (orbital cellulitis), particularly when a pocket of pus (abscess) forms, sometimes need surgical drainage in addition to antibiotics.

Tear Drainage Problems

When the tear-drainage system from the eye into the nose is blocked, a procedure called dacryocystorhinostomy (DCR) creates a new drainage pathway. This sits at the edge of orbital surgery and is often performed by the same specialists.

Optic Nerve Compression

When something inside the orbit — swelling, bleeding, or a mass — is pressing on the optic nerve and threatening vision, urgent surgery may be needed to relieve that pressure.

Vascular Lesions and Congenital Conditions

Some patients are born with abnormal blood vessels, cysts, or developmental differences in the orbit that may require surgery later in life.

Severe Disease Where the Eye Cannot Be Saved

In rare situations — for example, aggressive cancer that has spread into the orbit — a more extensive operation called orbital exenteration may be discussed. This removes the eye and surrounding orbital contents and is considered only when no other option preserves life or controls disease.

Types of Orbital Surgery

Because the underlying problems are so different, the operations themselves vary widely. Below are the main types your surgeon may discuss.

Orbital Decompression

Orbital decompression is most often performed for thyroid eye disease that causes severe bulging, exposure of the cornea, double vision, or pressure on the optic nerve. The surgeon removes carefully selected parts of the bony wall of the orbit — usually the floor, the inner (medial) wall, or the outer (lateral) wall — and sometimes some orbital fat. This allows the swollen tissues to settle into a larger space, easing the bulge and relieving pressure on the nerve.

European guidance from the European Group on Graves’ Orbitopathy (EUGOGO) describes decompression as the cornerstone surgical step when medical treatment of thyroid eye disease is insufficient or when sight is threatened.

Orbital Tumour Removal (Orbitotomy)

An orbitotomy is an operation that opens the orbit to remove or biopsy a tumour. The approach — through the upper or lower eyelid, the corner of the eye, the brow, or, less commonly, through the sinuses — depends on where the lesion sits. Many incisions are placed within natural skin creases or hidden behind the eyelid so the scar is minimally visible.

Orbital Fracture Repair

Repair of an orbital fracture usually involves lifting trapped tissue back into the orbit and supporting the broken floor or wall with a thin implant — commonly a titanium mesh, a porous polyethylene sheet, or a resorbable plate. Not every fracture needs surgery; small fractures without trapped muscle or significant eye displacement are often watched.

Drainage of Orbital Abscess

When an infection forms a pocket of pus in the orbit, draining it surgically — alongside intravenous antibiotics — is often necessary. This is usually an urgent procedure.

Optic Nerve Sheath Fenestration

In selected conditions where pressure around the optic nerve threatens vision, the surgeon may open the protective sheath around the nerve to release fluid. This is a specialised procedure performed in specific situations.

Dacryocystorhinostomy (DCR)

For chronic tearing caused by a blocked tear-drainage system, a DCR creates a new opening between the tear sac and the nose. It can be done through a small skin incision near the side of the nose (external DCR) or through the nose with an endoscope (endonasal DCR).

Orbital Exenteration

This is the most extensive orbital operation, performed only when an aggressive disease — usually cancer — cannot be controlled in any other way. It removes the eye and the contents of the orbit. Reconstruction options and the use of a custom orbital prosthesis are discussed in detail with the surgical team when this procedure is being considered.

Who Is a Candidate?

Whether a particular patient is a candidate for orbital surgery is a clinical judgement made by the surgical team, based on imaging, eye examination, the natural history of the underlying condition, and the patient’s overall health. Broadly, surgery is considered when one or more of the following apply:

• Imaging shows a tumour or mass that needs to be removed or sampled
• The optic nerve is being compressed and vision is at risk
• An orbital fracture has trapped muscle, caused the eye to sink, or led to persistent double vision
• Thyroid eye disease has become severe or sight-threatening despite medical treatment
• An infection has formed an abscess that needs draining
• A blocked tear duct is causing repeated infections or constant watering
• Eye protrusion is causing exposure damage to the cornea, severe discomfort, or significant distress

Before recommending surgery, the surgeon will usually arrange a detailed eye assessment — including vision testing, eye-pressure check, examination of the front of the eye and the retina, and tests of eye movement — together with imaging of the orbit (CT, MRI, or both). Blood tests may be needed if a systemic condition such as thyroid disease or an autoimmune disorder is suspected.

For some conditions, particularly thyroid eye disease, the timing of surgery matters. Major societies generally recommend that elective decompression for thyroid eye disease be done once the inflammatory phase has settled and the disease is stable, unless vision is acutely threatened.

Alternatives to Orbital Surgery

Not every orbital problem needs surgery, and a careful look at non-surgical options is part of any responsible plan. Depending on the underlying diagnosis, alternatives may include:

Medical Treatment

• Corticosteroids (oral or intravenous) to reduce inflammation, particularly in active thyroid eye disease or non-specific orbital inflammation
• Antibiotics for orbital cellulitis without abscess
• Thyroid hormone control, which is essential in thyroid eye disease but does not itself reverse advanced changes
• Biological therapies such as teprotumumab and rituximab, which have changed the medical landscape of thyroid eye disease in some countries and may reduce the need for surgical decompression in selected patients

Radiotherapy

Low-dose orbital radiotherapy is used in specific situations, including some cases of thyroid eye disease and certain lymphomas. Whether it is appropriate depends on the diagnosis and the team’s assessment.

Watchful Waiting

Some benign, slow-growing, or asymptomatic findings can be monitored with repeat imaging rather than removed straight away. This is more common with stable cysts, very small fractures without functional impact, and certain incidental findings.

Non-surgical Aids

For double vision from orbital disease, prism glasses can help while a patient waits for surgery or while inflammation settles. Lubricating eye drops, taping the eyelids at night, and protective glasses can manage corneal exposure caused by bulging.

The right balance between medical, observational, and surgical approaches is something to work out with your ophthalmologist and, where relevant, an endocrinologist, oncologist, or maxillofacial surgeon.

Surgical Approaches

Within orbital surgery, the surgeon may approach the orbit through several different routes. The choice depends on where the problem sits.

Anterior (Front) Approaches

Most commonly, the surgeon enters through an incision in the upper or lower eyelid crease, in the inner or outer corner of the eye, or just behind the eyelid through the inside lining (transconjunctival). These approaches are used for lesions sitting in the front or middle of the orbit, and for many fracture repairs. They generally leave well-hidden scars.

Lateral Approach

For tumours sitting on the outer side of the orbit, the surgeon may make an incision near the outer edge of the eyebrow or eyelid and, if needed, temporarily remove a small piece of the outer orbital bone to reach the lesion.

Endoscopic (Endonasal) Approach

For decompression of the inner wall of the orbit, drainage of medial-wall abscesses, and certain tear-duct surgeries, an endoscope — a thin instrument with a camera — can be passed through the nostril. This avoids a skin incision and is often performed in cooperation with an ear, nose and throat (ENT) surgeon.

Combined and Cranio-Orbital Approaches

Deep lesions sitting near the back of the orbit, near the optic nerve or extending towards the brain, may require a combined approach with a neurosurgeon. These are more complex procedures performed in centres with multidisciplinary teams.

Preparing for Orbital Surgery

Once orbital surgery has been planned, preparation usually involves several steps over a few days or weeks.

Pre-operative Assessment

The surgical team will check that you are fit for anaesthesia and that any other medical conditions (such as diabetes, high blood pressure, heart disease, or thyroid problems) are well controlled. Tests may include blood work, an electrocardiogram (ECG), and a chest X-ray. Imaging of the orbit — usually a CT scan, an MRI, or both — will be reviewed in detail to plan the operation.

Medication Review

Blood-thinning medications — such as aspirin, clopidogrel, warfarin, or direct oral anticoagulants — may need to be paused or adjusted before surgery to reduce bleeding risk. Do not stop any medication on your own; always discuss this with the team prescribing it and the surgical team.

Some supplements (including high-dose fish oil, vitamin E, and certain herbal products) can also affect bleeding and are usually paused for around two weeks before surgery.

Stopping Smoking

Smoking is strongly linked with worse outcomes in thyroid eye disease and with slower wound healing generally. Stopping smoking, ideally several weeks before surgery, is something major societies actively recommend.

Fasting and Final Checks

You will be given clear instructions about when to stop eating and drinking before surgery — usually from midnight the night before, with some sips of water allowed up to a few hours before, depending on the anaesthetist’s protocol.

Practical Preparation at Home

• Arrange someone to bring you home and stay with you for the first 24 hours
• Prepare loose, button-down clothing so you don’t pull anything over your head after surgery
• Set up a clean, quiet space for recovery, with extra pillows so you can sleep with the head elevated
• Stock up on soft foods, water, and any medication you have been prescribed
• Have ice packs or gel packs ready for the first 48 hours of swelling

What Happens During Orbital Surgery

The exact sequence depends on the operation, but most orbital surgery follows a similar broad pattern.

Anaesthesia

Most orbital operations are done under general anaesthesia, meaning you are fully asleep. Some shorter procedures — for example, certain biopsies or DCR — can be done under local anaesthesia with sedation.

Positioning and Preparation

You will be positioned on the operating table with the head supported. The area is cleaned with antiseptic and sterile drapes are placed, leaving the eye and surrounding face exposed.

The Incision and Surgery Itself

The surgeon makes the planned incision — often inside the eyelid or in a natural crease — and works carefully through the tissues using microsurgical instruments. Modern orbital surgery often uses:

• An operating microscope or surgical loupes for magnification
• An endoscope for endonasal routes
• Image-guided navigation, similar to GPS, in complex cases
• Specialised retractors that hold delicate tissues out of the way

Depending on the operation, the surgeon will then remove a tumour, lift trapped tissue, drain an abscess, remove a section of bone, or place an implant.

Closure

The incision is closed with fine sutures, some of which may dissolve. The eye is usually protected with ointment, and a light dressing or eye pad may be placed temporarily.

Duration

Most orbital operations take between one and three hours, though complex tumour removals or combined cranio-orbital procedures can take longer. You will then be moved to a recovery area for monitoring.

Recovery and Healing

The First Few Days

It is normal to have:

• Swelling and bruising around the eye and eyelid — often worst on day two or three
• Discomfort or aching, usually manageable with simple painkillers
• Blurred vision in the operated eye for a few days due to swelling and ointment
• A feeling of pressure or fullness behind the eye

You may be kept in hospital overnight, or for one to two nights for larger procedures, so the team can monitor vision, eye movement, and any signs of bleeding behind the eye. Some smaller operations are done as day cases.

The First Two Weeks

Most of the bruising fades over one to two weeks. Sutures, if non-dissolving, are typically removed at around one week. Many patients can return to desk-based work within one to two weeks, depending on how the recovery is going and what the job involves.

Weeks Four to Six

Swelling continues to settle. Eye movements that felt restricted by swelling usually improve. Mild numbness around the operated area can persist as small sensory nerves recover.

Three to Six Months

Final results — particularly the appearance after decompression or fracture repair, and the position of the eye — become clearer. Scars continue to mature and fade.

Aftercare Basics

• Sleep with the head elevated on two or three pillows for the first one to two weeks to reduce swelling
• Apply cold compresses for the first 48 hours, then gentle warm compresses if advised, to ease bruising
• Use prescribed eye drops, ointments, and antibiotics exactly as instructed
• Avoid heavy lifting, straining, bending forward, and vigorous exercise for the period your surgeon specifies — often two to four weeks
• Avoid blowing your nose forcefully after operations near the sinuses, as this can push air into the orbit
• Do not rub the eye
• Avoid swimming and dusty environments until cleared
• Wear sunglasses outdoors to reduce light sensitivity

Warning Signs to Report Urgently

Contact the surgical team without delay if you notice:

• Sudden loss or worsening of vision
• Severe pain that is not controlled by painkillers
• Rapidly increasing swelling, especially if the eye becomes hard or pushed forward
• High fever
• Pus-like discharge from the wound
• New or worsening double vision after initial improvement

These can indicate bleeding behind the eye, infection, or other complications that may need urgent treatment.

Risks and Complications

Orbital surgery is performed in a small, structurally complex space, and although outcomes in experienced hands are generally good, every operation carries risks. Knowing them helps you weigh the decision and recognise problems early.

General Surgical Risks

• Bleeding, including bleeding behind the eye (retrobulbar haemorrhage), which is rare but can threaten vision and needs urgent treatment
• Infection of the wound or orbit
• Reactions to anaesthesia
• Scarring

Risks Specific to Orbital Surgery

• Visual changes or vision loss. Serious vision loss is uncommon but possible, particularly when working close to the optic nerve.
• Double vision (diplopia). This can occur, particularly after decompression, fracture repair, or surgery near the eye muscles. It often improves over weeks to months, but sometimes a second procedure on the eye muscles is needed.
• Numbness of the cheek, upper lip, gums, or forehead from temporary or permanent injury to small sensory nerves.
• Dry eye or worsening of an existing dry eye.
• Eyelid position changes, such as a slightly different lid level or asymmetry between the two sides.
• Sinus problems, when surgery involves the wall between the orbit and the sinuses.
• Cerebrospinal fluid leak, very rare, from injury to the thin bone separating the orbit from the brain.
• Recurrence of the underlying problem — tumour regrowth, recurrent infection, or progression of thyroid eye disease — depending on the diagnosis.
• Need for further surgery, including planned staged procedures (for example, decompression followed later by eye-muscle surgery and then eyelid surgery in thyroid eye disease).

Your surgeon will discuss the specific risks that apply to your operation, based on the diagnosis and the route used.

Life After Orbital Surgery

For most patients, orbital surgery is one step in a longer journey of managing the underlying condition. What life looks like afterwards depends on what was treated.

After Surgery for Thyroid Eye Disease

Decompression often improves bulging, comfort, and pressure on the optic nerve. However, thyroid eye disease is a multi-stage condition. Patients sometimes need a sequence of operations: first decompression, then surgery on the eye muscles to correct double vision, and finally eyelid surgery to adjust lid position. Lifelong management of thyroid hormone levels, regular ophthalmology follow-up, and not smoking are central to long-term outcomes.

After Tumour Surgery

Long-term care depends on the type of tumour. Benign lesions that have been fully removed may need only occasional imaging follow-up. Malignant tumours often require additional treatment such as radiation or chemotherapy and long-term surveillance under an oncology team.

After Fracture Repair

Most patients see good restoration of eye position and resolution of double vision over weeks to months. Some residual numbness in the cheek or upper teeth can persist. Follow-up is usually shorter than for tumour or thyroid surgery, unless complications develop.

After Tear-Duct Surgery

Most patients notice significant improvement in watering. A small silicone tube may be left in place temporarily and removed in a clinic visit a few weeks later.

Returning to Work, Exercise and Daily Life

• Light desk work: often within one to two weeks
• Driving: only once vision is stable, double vision (if present) has settled, and your surgeon agrees
• Light exercise (walking): typically within one to two weeks
• Heavy exercise, contact sports, swimming, weight lifting: usually four to six weeks, sometimes longer
• Air travel: discuss timing with your surgeon, particularly after sinus-related procedures

Emotional Recovery

Surgery near the eye can be emotionally demanding. Bruising, temporary appearance changes, and uncertainty about vision can affect mood. Many patients find that knowing what to expect at each stage helps. If low mood or anxiety persists, mentioning it to the surgical team or your family doctor allows additional support to be arranged.

Orbital Surgery in Children

Children can also need orbital surgery, but the reasons and considerations differ from those in adults. Common paediatric indications include:

• Dermoid cysts — benign, well-defined cysts often found near the upper outer corner of the eye, usually removed in childhood
• Capillary haemangiomas — vascular growths that may need treatment if they affect vision development; many are managed with medication first
• Rhabdomyosarcoma — a rare childhood cancer of the orbit that requires urgent multidisciplinary care, usually combining biopsy, chemotherapy, and sometimes radiation rather than primary surgical removal
• Orbital cellulitis with abscess, which can spread rapidly in children
• Orbital fractures, including the so-called “trapdoor” fracture in younger children, where muscle can become trapped in the floor of the orbit. These often require earlier surgical attention than adult fractures
• Congenital tear-duct problems, when simpler measures have failed

Paediatric orbital surgery is generally carried out by oculoplastic surgeons who work closely with paediatric ophthalmologists, paediatric oncologists, and ENT or maxillofacial surgeons. Anaesthesia, imaging choices, and the timing of surgery are all adapted for children. Parents are typically involved closely in shared decision-making, and the team will explain how the child’s growing facial bones may influence both timing and technique.

Frequently Asked Questions

Will orbital surgery affect my vision?

In many cases, orbital surgery is performed to protect or improve vision — for example, by relieving pressure on the optic nerve or removing a compressive tumour. However, working close to the eye and optic nerve carries some risk to vision. The likelihood depends on the diagnosis and operation, and your surgeon will discuss the specific risk for you.

Will I have a visible scar?

Most modern orbital surgery uses incisions hidden in eyelid creases, behind the eyelid, in the eyebrow, or inside the nose, so visible scarring is usually minimal. Some approaches do leave a small skin scar, which generally fades over several months.

Will my eye look different afterwards?

Many orbital operations are designed to restore a more normal appearance — for example, by reducing eye bulging or correcting eye position after a fracture. Some changes in eyelid position, contour, or symmetry can occur, and additional small adjustments are sometimes planned as a second stage.

How long until I can drive again?

You can usually drive once your vision is clear, any double vision has settled, eye movements are comfortable, and your surgeon has agreed it is safe. For many patients, this is around one to two weeks for straightforward procedures, longer for more complex ones.

Will I need more than one operation?

In some conditions — particularly thyroid eye disease — a staged plan of two or three operations may be discussed from the start: decompression first, then eye-muscle surgery, then eyelid surgery, with gaps of several months between stages. Cancer treatment may also involve more than one procedure. Your surgeon will outline the expected sequence for your situation.

Can orbital surgery be done with local anaesthesia?

Most orbital operations need general anaesthesia because of the precision required and the discomfort of working in this area. A few procedures, such as some tear-duct operations or small biopsies, can be done under local anaesthesia with sedation.

How is the choice between endoscopic and open surgery made?

The choice depends on the diagnosis, the location of the problem, the surgeon’s training, and the equipment available. Endoscopic approaches avoid a skin incision but are not suitable for every condition. Your surgeon will explain which approach is recommended for you and why.

Can the underlying condition come back after surgery?

Recurrence depends on the diagnosis. Some benign lesions, once fully removed, do not return. Others — certain tumours, thyroid eye disease, and recurrent infections — can recur or progress, which is why long-term follow-up is important.

Is orbital surgery safe in older patients?

Age alone is not a barrier. Suitability depends on overall health, other medical conditions, and the specific operation planned. Pre-operative assessment will help the team adapt the anaesthesia and procedure accordingly.

Conclusion

Orbital surgery covers a wide range of operations performed in one of the most delicate areas of the body. Whether the goal is to relieve pressure on the optic nerve, remove a tumour, repair a broken socket, drain an infection, or restore tear drainage, the approach is highly individualised — shaped by the diagnosis, imaging findings, and the patient’s overall health.

Modern oculoplastic and orbital surgery, supported by high-resolution imaging and microsurgical technique, has made these operations safer and more precise than ever before. Outcomes are generally good when surgery is performed by experienced specialists, often as part of a multidisciplinary team that may include endocrinologists, ENT surgeons, neurosurgeons, oncologists, and paediatricians where relevant.

Understanding what kind of orbital surgery is being planned, what it involves, and what recovery looks like makes it easier to take part in the decisions ahead and to know what to watch for in the weeks and months afterwards. A detailed conversation with your surgeon — including the specific risks, alternatives, and expected sequence of care for your condition — remains the most important step in preparing for orbital surgery.
