A Clinical Study on the Incidence and Visual Outcome after Surgical Management of Lens-Induced Glaucoma

Abstract

Aims and Objectives: To determine 1) the incidence of lens-induced glaucoma. 2) the more prevalent type of LIG. and 3) Visual outcome following surgical management of LIG. Material and Methods: 50 patients of lens-induced glaucoma, who presented in OPD of Regional Institute of Ophthalmology, were included in the study. All patients were admitted and managed in indoor wards. Informed and written consents were taken. A detailed history and a thorough ocular examination was done. Surgical correction was done by SICS or Phacoemulsification or triple procedures operations. Results: A standardized proforma was used to compile data and it was analyzed statistically using Chi-square test and Probability value. The incidence of LIG was found to be 0.174 among all OPD attendees. Phacomorphic glaucoma (58%) was found to be the highest followed by phacolytic glaucoma (32%). No significant association with respect to sex and age of the cases was found. The presenting symptoms varied in severity and were directly proportional to the degree of rise of IOP. 38% of cases in our study achieved best corrected visual acuity of 6/9 and 28% achieved 6/12 acuity at the end of 6 weeks. Visual outcome was found to be better for cases with early detection and treatment. Conclusion: The mainstay to prevent and treat LIG is early diagnosis and treatment of cataract. Delayed treatment of LIG may result in poor visual outcome. Keywords: LIG, IOP, Phacomorphic glaucoma, Phacolytic glaucoma, SICS, Phacoemulsification.
