'Valve trabeculotomy' in glaucoma.

The surgical technique of "valve trabeculotomy" includes preparing the superficial and the inner limboscleral flaps while the midscleral lamina is excised. The operation was performed on 100 glaucomatous eyes of 82 patients. Postoperative complications included hyphema in 11 cases, mild iridocyclitis in four eyes, and choroidal detachment in six cases. Three to four weeks after surgery, the intraocular pressure was controlled (less than or equal to 21 mm Hg) in 96 eyes by surgery alone and in three eyes by surgery and medication. In 11 to 30 months (mean, 18 months) 95 eyes of 77 patients were examined. The IOP was controlled in 84 eyes by surgery alone and in five eyes by surgery and medication.
