ABSTRACT
We report the case of a young man with a 20-year history of insulin-dependent diabetes mellitus, proliferative diabetic retinopathy OD, and uveitis OS. None of the common reported causes contributing to this difference between eyes was present. No features of diabetic retinopathy appeared OS after a follow-up of 36 months. This is the first case, to our knowledge, in which uveitis appeared to be associated with an asymmetric presentation in diabetes.

The modification of corneal sensitivity, accommodation, pupillary diameter and endothelial cell density after argon versus krypton panretinal photocoagulation were studied prospectively in 88 eyes of 64 diabetic patients with proliferative diabetic retinopathy, randomized for one of the two laser treatments. In both groups a marked internal ophthalmoplegia and reduction of corneal sensitivity occurred after laser photocoagulation. At no time, 2, 90 and 180 days after PRP, were these parameters significantly different. Endothelial cell loss was non significantly greater in the krypton group. The results indicated that the side effects commonly observed on the anterior segment after PRP are comparable using argon or krypton lasers.

To evaluate the effectiveness of contact delivery systems, we treated 23 eyes with uncontrolled intraocular pressure using a continuous wave Nd:YAG laser delivered by a fiber optic. With the fiber's tip perpendicular to the surface of the conjunctiva, 1.5 mm from the corneal limbus, we applied 16 laser spots of 2 J/second energy. Patients were followed for at least 6 months (mean, 8.6 +/- 2.4 months). The mean pressure decreased from a pretreatment value of 43.7 mm Hg to a posttreatment value of 24.7 mm Hg (P = 0.000). A total of 66.6% of the treated eyes achieved a pressure on last follow-up visit of 25 mm Hg or less. Pain decreased in all the patients treated (P less than .005). Complications were minimal.
