[Modification of sinusotomy].

Sinusotomy modification, developed by the authors, consists in combination of traditional subscleral surgery with posterior cyclo-retraction and the formation of an uveal pouch. This technique was used in the treatment of 28 patients (28 eyes) with primary open-angle glaucoma. Immediate hypotensive effect was achieved in all the patients (in one case surgery was paralleled by pilocarpine instillations). Twenty-four patients were examined in late periods (up to 1 year) after surgery. Ophthalmic tone normalization was achieved in 91.7% of cases (in 83.3% of cases no drug instillations were used). Vision acuity and visual field were unchanged or improved in 87.5 and 95.8% of cases, respectively. No grave complications were recorded.
