Neovascular glaucoma after intracapsular and extracapsular cataract extraction in diabetic patients

A retrospective study of the rate of development of neovascular glaucoma after cataract extraction in 242 eyes of 186 diabetic patients identified neovascular glaucoma in 13 of 146 eyes (8.9%) after intracapsular extraction, in two of 17 eyes (11.8%) after extracapsular extraction with primary capsulotomy, and in zero of 53 eyes after extracapsular extraction without capsulotomy. The incidence of neovascular glaucoma was significantly lower in patients who underwent extracapsular extraction with preservation of an intact posterior capsule than in those undergoing intracapsular cataract extraction (P less than .01) or extracapsular cataract extraction with primary capsulotomy (P less than .05).
