epidemiology of ocular gunshot injuries in Cairo University Hospitals

This work is a retrospective survey of the files of ophthalmic emergency cases admitted to Cairo University Hospitals in the years 1989 and 1990, they were 2398 cases. Out of these, there were 67 cases [2.79%] of ocular gunshot injury, 81.6% of them were under thirty and sixty percent came in the 10- < 20 years group. The male female ration was 3.47:1. There were no seasonal peaks of admission. The type of gunshot could be identified in 30 cases; 16 were injured with airgun pellets, 12 with shotgun pellets and 2 with bullets. The type of injury, initial visual acuity and clinical presentation were studied. The high incidence of airgun and shotgun injuries calls for prevention

Glaucoma a clinico-experimental study of the effect of interaction of some anti-glaucoma drugs on the intraocular pressure

Many drugs are used in the management of glaucoma, each exerting its effect through a certain mechanism. The interaction of two or more of these drugs administered concomittently is of importance to the ophthalmologist. Such interaction may reduce the intraocular pressure [IOP], or may antagonize the intended therapeutic effect of any of them. The effect of pilocarpine, timolol, eserine and diamox, each alone and in different combinations was studied clinically in 149 eyes of chronic simple glaucoma, and experimentally in albino rabbits. The results showed that pilocarpine remains the most effective and safest topical drug for prolonged use in open angle glaucoma. The use of timolol is accompanied by two phenomena "the short term escape" and the "long term drift". Combining it with another drug after one year of its use is essential to keep its efficiency. Pilocarpine-acetazolamide is the most effective combination in reducing IOP compared to all other combinations
