Fig. 18 Panretinal photocoagulation with elevated intraocular pressure. A. Elevated intraocular pressure was noted in the first few hours following scatter laser photocoagulation of the proliferative diabetic retinopathy. B. Four days later the same patient noted blurred vision and was found to have peripheral choroidal detachments, a closed peripheral angle, and intraocular pressure of 35 mm Hg. Treatment with cycloplegics, topical corticosteroids, timolol maleate, and acetazolamide produced a rapid drop in pressure. The choroidal detachments resolved completely in 10 days.
