Composite drainage in glaucoma surgery

Полный текст:


PURPOSE. To assess the hypotensive effectiveness, frequency and nature of intra- and postoperative complications in patients with various clinical manifestations of refractory glaucoma.

MATERIALS AND METHODS. The study included 196 patients (196 eyes) with various forms, stages and clinical manifestations of glaucoma. There were 142 patients with primary glaucoma, among them 120 with open-angle glaucoma and 22 with angle-closure glaucoma. Among the patients with primary glaucoma, 85 had pseudophakia (77 with openangle and 8 with angle-closure forms); 57 had a native lens (43 with open-angle and 14 with angle-closure forms of the disease). Secondary glaucoma was presented mainly by patients with neovascular (21) and postuveal (16) glaucoma. The intraocular pressure (IOP) level in the group as a whole ranged from 16 to 50 mm Hg (on average 30.1±2.6 mm Hg). In all presented cases of surgical intervention, the Glautex drainage was used, which is a bioresorbable composite biomaterial based on polylactic acid (polylactide) and polyethylene glycol (manufactured by “HiBiTech”, Russia). Standard methods of patient examination were used. RESULTS.In patients with POAG, the IOP averaged 13.7± 4.7 mm Hg one week after surgery and 16.1±3 mm Hg 12 months after surgery. The absolute success of the operation was noted in 71 patients with POAG (59.2%); the relative hypotensive effect — in 85.8%. In primary angle-closure glaucoma, the same indicators were 47.6 and 61.1%, respectively. In the group of patients with neovascular and postuveal glaucoma, the hypotensive effect was as expected lower and amounted to 42.8 and 50.0%, respectively. The restart of therapy at different periods of observation was done in 78.3%. Complications, their frequency and nature, noted by us in the operated patients, could be attributed to those typical for fistulizing operations in refractory glaucoma. The most common complication was ciliochoroidal detachment, which was seen in all groups, but percentage-wise was more common in patients with PACG, neovascular and postuveal glaucoma.

CONCLUSION. Composite drainage based on polylactic acid (polylactide) and polyethylene glycol (glautex) is an effective and safe solution to the issue of surgical treatment of glaucoma. The antihypertensive effectiveness of the Glautex drainage implant depends on the severity of the glaucomatous process and the timeliness of the surgical intervention. The frequency and nature of complications depends on the degree of refractoriness of glaucoma, initial clinical characteristics of the process, and patients' multimorbidity.
