Résumé
Forty aphakic eyes, with secondary pupillary membranes, underwent pars plana membranectomy and YAG laser discission randomly. Visual improvement was similar in both the groups. IOP remained low for a week in pars-plana membranectomy while it transiently increased following YAG laser discission Complications like anterior chamber reaction, corneal edema and CME were more after pars plana membranectomy than in YAG laser discission. In membranes thicker than 1.2 mm, only pars plana membranectomy is recommended.

Argon laser iridoplasty was performed in 40 eyes of 33 patients of primary angle closure glaucoma. There were 12 male and 21 female patients. The mean ages of the male and female patients were 51 years and 48.4 years respectively. Forty eyes were divided into two groups. Group I consisted of ten eyes of subacute angle closure glaucoma and group II included thirty eyes of chronic angle closure glaucoma. Argon laser iridoplasty was performed with Coherent 9000 model using laser settings of spot size 200 micron, duration 0.2 second and power 0.7 watt. A total of 80 spots were applied over 360 degree circumference. The intraocular pressure control (below 22 mm Hg) was achieved after iridoplasty in all the eyes (100%) in group I, where as in group II the intraocular pressure was controlled in 70% eyes. The follow up period varied from 3 months to one year with a mean of eight months. The success rate with iridoplasty was directly related to the extent of peripheral anterior synechiae, optic disc cupping and presence of visual field changes.

Conjunctival sacs of seventy one leprosy patients, paramedical and medical personnel working in a leprosy home were cultured. None of these eyes had any pathology in the outer eye. Surprisingly, 46.2% of the eyes which showed a positive culture carried accepted pathogens; Staphylococcus aureus being the commonest. Determining the preoperative bacterial flora and their elimination before undertaking intraocular surgery is recommended.
