A Clinical Study of Lens Induced Glaucoma

Abstract

Background and aims: There is an ever-increasing backlog of cataract due to the population explosion, increased life expectancy, and low productivity in terms of utilization of the available surgical services. The present study has endeavoured to determine the characteristics, risk factors, and their consequences on postoperative visual outcome, intraocular pressure (IOP), including optic disc changes in LIGs.Materials and methods: This prospective hospital-based study includes a total number of 80 cases of lens induced glaucoma patients who were clinically examined to diagnose the type of LIG. All aspects of the lens induced glaucoma’s namely, the age, sex incidence, complaints and their duration, clinical features of various forms of lens induced glaucoma’s, pre-operative management, surgical procedures done and post-operative follow up have been recorded. Results: The total number of cases studied were 80, of which 52 were female and 28 were male showing that occurrence of LIG is more common in females . Numbers of cases were more in the age group of 60- 75 years showing lens induced glaucoma is a condition of old age. Most common type was found to be phacomorphic type of lens induced glaucoma. The occurrence of phacoanaphylactic glaucoma and glaucoma due to subluxation of lens. BCVA at 6 weeks post operatively was 6/18 or better in 57.5% patients. Visual outcome bears a definite relationship with the duration of symptoms. BCVA of 6/6-6/18 in 77.6% of cases was attained in patients with duration of symptoms of less than one week. The postoperative IOP was within normal limits in 87.5% of patients. Conclusion: Despite the widespread availability of cataract surgical treatments, inadequate health education and a lack of awareness of symptoms and disease were identified to be the primary causes of LIG. There is need for public health education regarding the need of timely surgery for a better visual prognosis.
