Management of “Lens Induced Glaucoma”-A Clinical Study

Abstract

Aim: To study the incidence of lens induced glaucoma (LIG), various modes of presentation in different types of LIGs and to assess the visual outcome following management of LIGs. Materials And Methods: The present study was conducted on the patients who presented with Lens induced glaucoma in the outpatient department of the Regional Institute of Ophthalmology, Gauhati Medical College & Hospitals, Guwahati during the period September 2014 to August, 2015. Altogether 51 patients presented with lens induced glaucoma during this period of study. All patients were admitted in the ophthalmology department. Informed and written consents were taken. All cases diagnosed as LIG irrespective of age, sex and clinical types were clinically investigated and managed. Results: The data were compiled using a standardized performa and at the end of the study the data was analyzed statistically using the Chi-Square method and the Probability value. Incidence of LIG during the period of study was 0.15 % amongst all OPD attendance. Phacomorphic glaucoma (58.86 %) was higher in incidence compared to Phacolytic glaucoma (33.33 %) followed by 5.82 % of lens particle glaucoma and 3.92 % of glaucoma secondary to lens dislocation. In our study 58.82 % of cases achieved best-corrected visual acuity at the end of final follow up at 6 weeks. 35.29 % cases achieved visual acuity between 6/18-6/60 and 5.88 % regained visual acuity less than 6/60. Conclusion: Early diagnosis and treatment of mature cataract is very important since delayed treatment of LIG may result in poor visual outcome. There is a great need to impart health education to the public about the importance of timely surgery for better visual outcome.
