Ahmed Glaucoma Valve (AGV)
Valved drainage device commonly used for neovascular, uveitic, traumatic, and congenital glaucoma; safe even when intra-ocular pressure is very low.
Treatment · Glaucoma
Glaucoma valve surgery (also called glaucoma drainage device or tube shunt surgery) places a small implant on the surface of the eye to drain fluid and lower intra-ocular pressure. It is used when eye drops, laser treatment, and conventional trabeculectomy have not been enough — or when the type of glaucoma makes standard surgery risky.
Valved drainage device commonly used for neovascular, uveitic, traumatic, and congenital glaucoma; safe even when intra-ocular pressure is very low.
Non-valved implant with larger surface area — often chosen for eyes with prior surgery or higher target IOP.
Classic non-valved single or double plate drainage implant; excellent long-term pressure control.
Newer small, flexible, non-valved implant with a lower bleb profile — faster visual recovery.
Malignant (ciliary block) glaucoma is a rare but serious complication after incisional glaucoma or cataract surgery in which fluid is trapped behind the vitreous. Treatment includes intensive cycloplegics, hyperosmotics, and — when needed — laser hyaloidotomy or vitrectomy. Our team manages these complex cases with the same consultants who handle valve surgery.

'Common Questions'
A glaucoma valve (Ahmed, Baerveldt, or ClearPath) is a small implant that creates a controlled drainage pathway to lower eye pressure when drops, laser, and trabeculectomy are not enough.
Patients with uncontrolled pressure despite drops, SLT, and prior trabeculectomy; patients with neovascular or uveitic glaucoma; and patients whose conjunctiva is too scarred for standard filtration surgery.
Modern valves typically last many years — often a lifetime. We monitor their function at every follow-up and clear any tube obstruction early to keep them working smoothly.
Usually far fewer drops — sometimes none. We tailor the post-op drop plan to your new, lower pressure and adjust over the first 6 months as the eye settles.
Light activity resumes within a week; full activity by 4–6 weeks. Expect to be seen 4–6 times in the first 6 weeks so we can titrate pressure and remove any temporary suture that controls flow.
