ABSTRACT
The combined use of goniophotocoagulation and carotid endarterectomy may be an important mode of treatment of iris neovascularization caused by carotid insufficiency. Carotid operation alone in cases of iris neovascularization has not been successful in controlling the concomitant or ensuing neovascular glaucoma. When more severe symptoms of carotid occlusion occur, such as transient ischemic attacks or visual loss, it may be too late to reverse the damage of neovascular glaucoma. In this case report, early detection of the iris neovascularization, goniophotocoagulation, and carotid operation were successful in the prevention of neovascular glaucoma and blindness.

Fifty-three patients with typical and reticular degenerative retinoschisis were evaluated. They demonstrated a corrected visual acuity of 20/20 except when some independent and unrelated ophthalmic condition was present. With a special protocol of test procedures, macular function in nine degenerative retinoschisis patients was found not significantly different from macular function in nine control patients. Macular function prognosis associated with degenerative retinoschisis is favorable, and implications for differential diagnosis are presented.

One hundred seventy-five consecutive and unselected patients with retinal detachment were treated with a scleral buckling procedure without inducing a thermal adhesion. In 143 (82%) of these patients reattachment was successful after one operation. In 32 patients (18%) reattachment was not initially successful. These failures resulted from buckle malposition, periretinal proliferation, new or missed breaks, and the inability to close giant tears. Fifteen of the 32 reattached after subsequent scleral buckling without thermal adhesion. Final success was achieved, therefore, in 158 (90%) of the original group of 175 cases. We concluded that a chorioretinal scar might have prevented initial failure only in those cases of buckle malposition. The high incidence (17, [10%]) of periretinal proliferation, accounting for all of our final failures, did not concur with or support previous impressions indicating a causal relationship between thermal treatment and proliferative complications.
