Panretinal Photocoagulation in the Management of Neovascular Glaucoma

We report a retrospective evaluation of the role of panretinal photocoagulation in the primary treatment of neovascular glaucoma. Thirty-six eyes (32 patients) received aggressive argon laser panretinal photocoagulation beginning as soon as feasible after diagnosis of the developing neovascular glaucoma. Thirty eyes were stabilized by photocoagulation, though 25 required long-term glaucoma medications. Six eyes required additional procedures. Vision deteriorated in 21 of the 36 eyes (nine eyes finally having "no light perception") during the 32.8-month follow-up. Intraocular pressure averaged 39.0 mm Hg before photocoagulation and 21.2 mm Hg at study's end. All 36 eyes were retained and remain comfortable. We conclude that panretinal photocoagulation plays an important role in the management of neovascular glaucoma.
