Clinical study of lens induced glaucoma

Abstract

Background: Lens induced glaucoma is a common occurrence. Secondary glaucoma has been found in 10% of senile cortical cataracts. Ruling out the coexisting primary glaucomas, lens induced glaucomas has been taken up for this interesting study. Objective: To analyze the different mechanisms and clinical features of lens induced gluacomas. Methods: This clinical study included 50 cases of different types of lens induced glaucomas in individuals whose age group varied from 12 to 90 years and both the sexes conducted on the in patients of Ophthalmology department. All the cases of secondary glaucomas suspected to be lens induced were admitted to the wards. Detailed history was ascertained. Previous history of extra-capsular lens extraction in the other eye was carefully noted. Results: Majority of the patients were in the age group of 50-75 years. The incidence of lens induced glaucoma was more among females (68%) than males (32%). Right eye was found to be more commonly affected (58%) than the left eye (38%) and both eyes were involved in 4% of cases.. The majority of the eyes affected had hypermature cataract (44%) followed by mature cataract (34%). Phacomorphic glaucoma caused by intumescent lens has been the major cause contributing to 54% of cases. 27 cases (54%) showed shallow anterior chamber. Conclusion: The incidence of lens induced glaucoma was more among females (68%) than males (32%). Right eye was found to be more commonly affected (58%) than the left eye (38%).Both eyes were involved in 4% of cases. The majority of the eyes affected had hypermature cataract (44%).
