In age-related macular degeneration, communication between the retinal and choroidal circulations occurs spontaneously or following unsuccessful laser photocoagulation of subretinal new vessels. The resulting chorioretinal anastomotic complex, which includes the subretinal new vessels and their feeder retinal vessels, usually shows marked exudation and produces an extensive serous detachment of the neurosensory retina in the posterior pole, often associated with hard exudates. Eleven eyes with chorioretinal anastomotic complexes were treated using the monochromatic green argon laser. Adequate closure of the chorioretinal anastomotic complexes by photocoagulation resulted in retinal flattening in the posterior pole with resolution of the hard exudates and improvement of vision in eight of the 11 treated eyes.

Of 27 eyes with peripapillary choroidal neovascular membranes (PPCNM), 17 (63%) had age-related macular degeneration and ten (37%) were idiopathic. PPCNM were treated in 25 eyes using the monochromatic green argon laser. Two eyes were untreatable. After an average follow-up of 37.7 months, successful closure of the choroidal new vessels was obtained in 23 eyes (92%), and visual acuity was stabilized or improved in 20 (80%). Seven eyes (28%) had recurrences; in four, the new vessels extended into the macula. Post-treatment, three eyes ultimately had dry macular scars, and one had an exudative macular scar. Of these four eyes, only the one with a dry macular scar showed visual improvement. No treated cases showed arcuate scotoma.

A 34-year-old Caucasian woman was diagnosed as having a pigmented iris tumor showing recent growth and satellite lesions. The tumor was associated with pigmentation of the anterior chamber angle and secondary unilateral glaucoma. After local excision, histopathologic studies revealed the plump polyhedral cells typical of melanocytoma. However, the examination of additional sections showed evidence of malignancy. The diagnosis of a melanocytoma that transformed into malignant melanoma was made and later confirmed by electron microscopic studies. Following surgical excision of the tumor, the eye maintained normal intraocular pressure. There was no evidence of recurrence 4 years after surgery.
