Combined surgical intervention at terminal glaucoma

Abstract

Purpose: to investigate hypotensive efficiency of new surgical intervention at terminal primary and neovascular glaucoma.Methods. Operation has been executed on 35 eyes of 35 patients with terminal primary (23 eyes) and secondary (12 eyes) neo- vascular glaucoma. A fornix based conjunctival flap was prepared in inferior part of a limbus. 1.5 mm transparent scleral incision 3 mm from limbus was performed. Goniocyclodialysis with spatula was carrying out. then 0.3 ml of viscoelastic solution was entered in cyclodialysis cleft. On sclera put cryoapplications, located in two ranks (on 6 in everyone). the period of postoperative follow-up has averaged 15.6±1.3 months.Results: In 1 month IOP did not exceed 25 mm hg and the painful syndrome has been stopped in all cases. In 1 year after operation normalization IOP took place on 27 eyes (77.2%), from them on 8 was local hypotensive therapy added. With 8 patients (22.8%) IOP instillation of 2 preparations remained at level of 28-30 mm Hg, however the painful syndrome was absent.Conclusion: Long-term hypotensive effect of new operation is reached at the expense of the double mechanism: reduction of production of aqueous humor for the account cryopexy of ciliary body and improvements aqueous outflow for formations cyclodialysis cleft.
