Recovery from Neovascular Glaucoma after Treatment with Ahmed Glaucoma Valve Implantation in Ocular Ischemic Syndrome

ABSTRACT

Ocular ischemic syndrome is caused by reduction of blood to the eyeball, which can prodece anterior and posterior segment ischemia. Initial symptom include sudden or gradual loss of vision and eyeball pain. Anterir segment findings are conjunctival injection, iris neovascularization(NV), angle NV,peripheralanterior synechiae, and lens opacity. Posterior segmentfindings are pale, cupped of edematous opticdisc, disc NV, retinal NV, retinal hemorrhage, cherry red spot, retinal arterioles attenuation or sclerosis, and centralretinal artery collapse with pressure on globe. We have experienced a patient who had left ophthalmic artery stenosis, right ophthalmic artery narrowing and neovascular glaucoma in both eyes. We report the case of ocular ischemic syndrome that had control of IOP, mild improvement of visual acuity and regression of neovascularization after Ahmed glaucoma valve implantation.
