<p><strong>Purpose</strong>: to investigate hypotensive efficiency of new surgical intervention at terminal primary and neovascular glaucoma.<br /><strong>Methods</strong>. 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 <strong>months.</strong><br /><strong>Results:</strong> 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.<br /><strong>Conclusion</strong>: 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.</p>
