Long-term results of modified trabeculectomy with supramid implant for neovascular glaucoma

Sixteen patients with neovascular glaucoma and residual visual function underwent modified trabeculectomy, including insertion of a Supramid sheet under the scleral flap. After 1 to 8.5 years of follow-up the intraocular pressure was substantially reduced in 12 patients and was maintained at 22 mm Hg or less in 10. Four patients were able to discontinue their medical therapy, and in 10 others it was considerably reduced. Functional filtering blebs were obtained in 12 patients. Visual acuity was about the same after surgery as before surgery in 8 of the 12; among the 4 others, visual loss was attributed to progressive cataracts in 2 and to macular degeneration in 2.
