What is Glaucoma?

Glaucoma is a group of eye conditions that damage the optic nerve, usually caused by abnormally high pressure inside the eye (intraocular pressure, or IOP). The optic nerve carries visual information from the eye to the brain, and progressive damage to it leads to gradual, irreversible vision loss, often starting with peripheral (side) vision. Because early glaucoma typically has no symptoms, it is frequently called the “silent thief of sight.” Left untreated, glaucoma can lead to complete blindness.

Glaucoma is broadly classified into open-angle glaucoma (the most common form, developing slowly over years) and angle-closure glaucoma (which can develop suddenly and is considered a medical emergency). Other forms include normal-tension glaucoma, congenital glaucoma, and secondary glaucoma caused by injury, inflammation, or other eye diseases.

What is Glaucoma Surgery (Trabeculectomy)?

When eye drops and laser treatment are not enough to control intraocular pressure, surgery becomes necessary to prevent further optic nerve damage. Trabeculectomy is the most established and widely performed surgical procedure for glaucoma. It creates a new drainage pathway for the fluid (aqueous humor) inside the eye, allowing it to drain out and lowering eye pressure.

In addition to conventional trabeculectomy, Minimally Invasive Glaucoma Surgery (MIGS) techniques are now available, offering quicker recovery and fewer complications for suitable candidates. For patients with refractory (difficult-to-control) glaucoma, our hospitals also offer Ahmed Glaucoma Valve (AGV) implant surgery, a specialized drainage device implant procedure.

The right procedure for each patient depends on the type and severity of glaucoma, prior treatments, and overall eye health, and is determined after a detailed evaluation by the treating ophthalmologist.

Why is Glaucoma Surgery Recommended?

• -Eye drops and oral/topical medications are no longer controlling intraocular pressure adequately
• -Laser treatment (such as SLT or laser iridotomy) has not achieved the target eye pressure
• -Glaucoma is progressing despite maximum tolerated medical therapy
• -Patient is unable to tolerate medication side effects or cannot maintain a strict drop schedule
• -Optic nerve damage or visual field loss continues to worsen on repeat testing
• -Angle-closure glaucoma requires urgent pressure reduction to prevent rapid vision loss
• -Congenital or juvenile glaucoma in children, which usually requires surgery as first-line treatment
• -Advanced glaucoma at diagnosis, where immediate pressure control is needed to preserve remaining vision

How is Glaucoma Surgery (Trabeculectomy) Performed?

Benefits of Glaucoma Surgery

• -Effectively lowers intraocular pressure, often achieving better and more sustained control than medication alone
• -Slows or halts further optic nerve damage, helping preserve remaining vision
• -Reduces dependence on multiple daily eye drops and their long-term side effects
• -Can be combined with cataract surgery in a single procedure when both conditions are present
• -Long track record of safety and effectiveness, refined over decades of clinical use
• -MIGS options offer a faster-recovery alternative for select patients with mild-to-moderate glaucoma

Risks and Potential Complications

As with any intraocular surgery, glaucoma surgery carries some risks, which the treating surgeon will discuss in detail before the procedure. These can include low eye pressure (hypotony), bleb-related infection, cataract formation or progression, bleeding inside the eye, and, uncommonly, scarring of the new drainage opening requiring further treatment (needling or repeat surgery) to restore its function. Most complications are manageable when identified early through regular post-operative follow-up.

Post-Surgical Recovery & Activity Restrictions

• -Initial recovery period of 1-2 weeks, with vision gradually stabilizing over 4-6 weeks
• -Prescribed antibiotic and anti-inflammatory eye drops must be used exactly as directed
• -Avoid rubbing or pressing on the operated eye; a protective shield is often worn at night
• -Avoid swimming, heavy lifting, and strenuous exercise for at least 4 weeks or as advised
• -Avoid air travel until cleared by the surgeon, typically after the first follow-up visit
• -Regular follow-up visits are essential to monitor eye pressure and bleb function
• -Most patients can resume light daily activities and reading within a few days

When to Contact Your Doctor Immediately

• -Sudden or severe eye pain, or a marked increase in redness
• -Sudden decrease in vision or new visual disturbances
• -Discharge, excessive tearing, or signs of infection around the eye
• -Nausea or vomiting accompanying eye symptoms after surgery

Alternatives to Glaucoma Surgery

Surgery is generally considered once other options have been tried or are unlikely to succeed. Alternatives include prescription eye drops (prostaglandin analogues, beta-blockers, and others) to reduce fluid production or improve drainage, oral medications for short-term pressure control, and laser procedures such as Selective Laser Trabeculoplasty (SLT) or laser iridotomy. Regular monitoring alone may be appropriate for very early or slowly progressing cases under close specialist supervision. Your ophthalmologist will recommend the most appropriate option based on the type and stage of glaucoma.
