[Injurious effects on the rhesus monkey eye from dye laser iridotomy].
8 normal rhesus monkeys were performed dye laser iridotomy in one eye and iridectomy surgery in the other. Another 7 normal rhesus monkeys were performed dye laser iridotomy in one eye and ruby laser iridotomy in the other. The protein content and the number of white blood cells in the aqueous humor, the intraocular pressure, and the ultrastructural changes in the pars plicata of the ciliary body and iris were observed after the operation. It was demonstrated that the intercellular space of the endothelium of the blood vessels in the iris might, like the intercellular space of the non-pigment epithelium in the pars plicata of the ciliary body, be the site of the blood-aqueous barrier of the eye. It was also shown that among these three modalities, dye laser iridotomy was the best, which induced the least injury to the blood-aqueous barrier with the shortest time for recovery and the least inflammatory reactions in the anterior segment of the eye.
