Iris epithelium detachment - An uncommon complication of Nd:YAG laser capsulotomy.

Purpose: To report a case of iris epithelium detachment following Nd:YAG laser capsulotomy.

Observations: We describe the case of an 81 year old woman who developed hyphema and detachment of the iris epithelium following standard Nd:YAG laser capsulotomy. The detachment was readily visualized using anterior segment OCT.

Lack of effect of nitroglycerin on the diameter response of larger retinal arterioles in normal persons during hypoxia.

Purpose: Retinal hypoxia with consequent changes in blood flow play a role in a number of vision-threatening diseases, such as diabetic retinopathy. Previous studies have shown that the inhibition of nitric oxide synthase (NOS) and cyclooxygenase (COX) products are involved in the diameter regulation of the retinal vessels during hypoxia. Therefore, the aim of the present study was to examine the effects of an NO donor combined with COX inhibition on the diameter regulation of retinal vessels during hypoxia in normal persons.
