Effects of Nd-Yag laser vitreolysis on lens and vitreous prostaglandins in the rabbit eye.

Abstract

This study concerns the quantitative modifications of the prostaglandins, PGF alpha e PGE2, in the vitreous and in the lens following the application of Nd-Yag Laser. Five minutes after the Yag-laser treatment, an increase of PGF1 alpha concentration of PGE2 decreased in the lens and increased in the vitreous. These changes, similar to those occurring in the aqueous humor, may be related to the activation of specific enzymatic pathways of prostaglandin synthesis.
