ABSTRACT
The development of subretinal neovascularization as a complication of retinochoroidal coloboma has been reported in only three cases, in only one of which was the patient treated with laser photocoagulation. We report an additional case of subretinal neovascularization associated with retinochoroidal coloboma in a 57-year-old man that was treated with laser photocoagulation. The patient's visual acuity has remained stable at 20/50.

We used peripheral retinal cryopexy to treat 20 eyes in 15 patients with subtotal vitreous hemorrhage secondary to proliferative diabetic retinopathy. In 18 eyes, complete panretinal photocoagulation had been performed before the subtotal vitreous hemorrhage and the subsequent cryopexy. The length of follow-up averaged 16 months. The vitreous hemorrhage completely cleared in 11 eyes (55%) and partially cleared in six eyes (30%). Visual acuity after treatment improved in 13 eyes (65%), remained unchanged in six eyes (30%), and decreased in one eye (5%).

The rationale for early identification of the stage of diabetic retinopathy immediately preceding development of fibrovascular proliferation is that early diagnosis affords the opportunity to treat by photocoagulation or other methods at the appropriate stage of retinal disease. Aids to identification include: venous abnormalities, intraretinal microvascular abnormalities, "cotton-wool" spots and fluorescein angiographic evidence of capillary non-perfusion. Although no one of these fundus changes is specific for the pre-proliferative stage of diabetic retinopathy, the presence of more than one of these findings increases the risk of subsequent fibrovascular proliferation. The development of frank proliferation frequently occurs within two years of first appearance of the preproliferative stage.
