Summary
The eye socket (the orbit) contains the eye, the muscles that move it, the optic nerve, fat, blood vessels and the lacrimal gland, all packed into a confined bony space. Tumours of any of these tissues can present as bulging of the eye, double vision, pain, or a visible lump. Orbital surgery for these lesions is precise, imaging-guided work performed by a small group of subspecialists.
Who is this for?
Patients I commonly see:
- a slow- or rapidly-progressive proptosis (bulging eye) on one side,
- a palpable mass in the upper outer orbit (often a lacrimal-gland lesion),
- an MRI finding of an orbital lesion needing biopsy,
- patients with a known systemic condition (lymphoma, IgG4-related disease, granulomatosis) being investigated for orbital involvement,
- vascular lesions causing distortion of the eyelid or eye position.
What the procedure involves
Procedures are individualised. Common operations include:
- Anterior orbital biopsy: for accessible lesions in the front of the orbit, via a small lid incision under local or general anaesthetic.
- Lateral orbitotomy: a discreet incision at the outer corner to access the lateral orbit and lacrimal gland.
- Medial orbitotomy: via a transcaruncular or ‘open’ approach for medial lesions.
- Joint procedures with skull-base surgical colleagues: for deep lesions approaching the optic canal.
Pre-operative imaging is reviewed in detail and the procedure is planned to maximise diagnostic yield while minimising risk to the eye and optic nerve.
Recovery and what to expect
- An overnight stay is common after orbitotomy.
- Bruising and swelling for 1–2 weeks.
- Sutures removed at 7 days.
- Histology results and a management plan typically take 2–3 weeks.
Risks and alternatives
Orbital surgery has small but important risks: bleeding, double vision, ptosis, numbness, scarring, and very rarely visual loss. Each procedure is planned to keep these risks to a minimum.
Many lesions can be observed or biopsied minimally rather than excised; the decision is always individualised.
