A PRESSURE LOWERING EFFECT OF RETINAL XENON PHOTOCOAGULATION IN NORMOTENSIVE DIABETIC EYES

Abstract
In 10 diabetic patients with normal intraocular pressures, the effect of monocular panretinal Xe photocoagulation was recorded with the applanating suction cup tonograph applied bilaterally. One month after the treatment, the photocoagulated eyes showed a statistically significant average decrease in pressure of approximately 3 mmHg (P < 0.001) when compared to the untreated fellow eye. The decreases were of similar magnitude (approximately 25%) to those after photocoagulation in neovascular glaucoma.
