[Current trends in neovascular glaucoma treatment]

Area of Science:

• Ophthalmology
• Glaucoma Research
• Retinal Vascular Diseases

Context:

• Neovascular glaucoma (NVG) is a severe secondary glaucoma characterized by neovascularization of the iris and anterior chamber angle.
• It often arises secondary to conditions like central retinal vein occlusion (36%), diabetic proliferative retinopathy (32%), and carotid artery obstruction (13%).
• NVG presents in three clinical stages: rubeosis iridis, secondary open-angle glaucoma, and synechia (angle-closure glaucoma).

Purpose:

• To synthesize current data on the clinical presentation, etiology, and management of neovascular glaucoma.
• To highlight the importance of early diagnosis and pain management in NVG.
• To review key surgical interventions for neovascular glaucoma.

Summary:

• Neovascular glaucoma is classified into three stages: rubeosis iridis, secondary open-angle glaucoma, and angle-closure glaucoma due to synechia.
• Common causes include central retinal vein occlusion (36%), diabetic retinopathy (32%), and carotid artery disease (13%).
• Effective management hinges on early diagnosis and pain relief, as visual prognosis is generally poor. Surgical options include trabeculectomy, drainage shunts, and laser cyclo-ablation.

Impact:

• Emphasizes the critical role of timely diagnosis in managing neovascular glaucoma.
• Underscores the poor visual prognosis associated with neovascular glaucoma, shifting focus to pain management.
• Provides an overview of established and emerging surgical treatments for neovascular glaucoma, aiding clinical decision-making.
