Neovascular Glaucoma: A Retrospective Analysis of Treatment With Peripheral Panretinal Cryotherapy

ABSTRACT A retrospective analysis of thirty-one eyes in thirty patients with neovascular glaucoma (NVG) associated with proliferative diabetic retinopathy or venous occlusive disease was performed. Eyes treated with transconjunctival peripheral panretinal cryotherapy alone, or in combination with limited cyclocryotherapy had improvement or stabilization of visual acuity in 55%, reduction of intraocular pressure in 55%, and stabilization or regression of iris neovascularization in 70% of eyes at 12-14 months post-treatment. Transconjunctival peripheral panretinal cryotherapy alone, or in combination with limited cyclocryotherapy is recommended in the treatment of eyes with NVG and media opacities precluding photocoagulation therapy, or in eyes unresponsive to previous photocoagulation therapy.
