PURPOSE The purpose of the study is to determine the efficacy and safety of Mitomycin C (MMC) augmented slit-lamp needle revision of failed filtration surgery. METHODS The authors retrospectively reviewed the charts of 62 patients (62 eyes) (age, 72 +/- 15 years) with failed filtration surgery who underwent needle revision using MMC. A mixture of 0.01 ml(More)
PURPOSE Cataract and glaucoma commonly coexist in elderly patients and present complex treatment options. This study investigates the results of simultaneous treatment of both conditions using phacoemulsification with posterior chamber lens implant and mitomycin-augmented trabeculectomy (combined surgery). METHODS A retrospective analysis was performed of(More)
Eighty-six eyes of 46 patients were studied retrospectively to determine the incidence of posterior synechiae after laser iridectomy. All eyes were dilated and studied with a slit lamp. The incidence of permanent posterior synechiae in the eyes in this study (37%) is much higher than that previously reported. There was a strong positive correlation between(More)
We tested 145 samples of 20 different topical medications for the treatment of glaucoma to determine the average drop size of each preparation. The average drop volumes of different preparations varied between a minimum of 25.1 microliter and a maximum of 56.4 microliter, with an average drop volume of 39.0 microliter. Our findings contradict the common(More)
Krypton red (647.1 nm) or krypton yellow (568.2 nm) laser trabeculoplasty was performed in 15 phakic eyes of 14 patients. After an average follow-up of five months, these patients had an average drop of intraocular pressure of 8.9 mm Hg. In addition, in eight of these patients studied, argon laser trabeculoplasty was performed in the opposite eye. After an(More)
Two patients with talc emboli of the retinal vasculature, both of them intravenous drug abusers, are described. One underwent a pars plana vitrectomy for removal of the vascularized vitreous mass that obscured the retina. The vitreous mass was presumably a result of retinal neovascularization secondary to the talc embolic. Other ocular findings that may be(More)
The following article discusses the outcome of 60 eyes with various forms of glaucoma undergoing resident-performed argon laser trabeculoplasty (ALT). The majority (46/60) of eyes had primary open-angle glaucoma. Decrease in intraocular pressure (IOP) was not as great as reported in the literature. Our results suggest that initially treating 180 degrees of(More)
