[Effects of trans-scleral laser cyclo-coagulation on intraocular pressure and visual function in patients with far advanced open-angle glaucoma].

Transscleral diode laser cyclocoagulation was modified so that laser coagulants (20-25 applications) were applied not only to the ciliary crown, but to the flat part of the ciliary body as well. Inflammation modulators forming after coagulation thus enter aqueous humor and the vitreous body and penetrate into the retina and optic disc, causing dilatation of capillaries and stimulating the blood stream in them. Forty patients (40 eyes) with far advanced glaucoma and pronounced concentrical narrowing of the visual field were operated on and observed for 6-12 months postoperation. One month after the intervention intraocular pressure decreased by 9-21 mm Hg and was below 22 mm Hg in 38 eyes; visual acuity increased by 0.1-0.3 in 11 cases; visual field widened in all patients. These results did not appreciably change till the end of the period of observation.
