Abstract
INTRODUCTION: In the developing nations, one of the leading causes of secondary glaucoma is Lens induced Glaucoma due to hyper mature cataract. A steady improvement in life expectancy rate and population explosion, increase the backlog of untreated cataract. LIG increases the pre-operative and post-operative morbidity compared to simple uncomplicated cataract. Irrespective of the surgical intervention visual outcome are affected to some extent and the prognosis guarded. Hence timely intervention is important in achieving good results. The importance of patient education, early diagnosis of cataract, and treatment of all cases of cataract before they go for complications necessitates the need for this study. AIM OF THE STUDY: To assess the final visual outcome in different types of lens induced glaucoma after surgical management. OBJECTIVES: To study the various modes of presentation of different lens induced glaucoma. To assess the factors influencing the final visual outcome. MATERIALS AND METHODS: This cross sectional observational study was undertaken to study the different types of LIG. This study included 98 patients with various types of lens induced glaucomas. The patients were followed up from the time of admission and surgery till 4 weeks post-operatively. The factors influencing the final visual outcome were analysed. RESULTS: In our study, with mean age of the patients presenting with LIG being 63.78±8.88 years. The most common type of LIG in our study is phacomorphic glaucoma which accounts to 58.16% The fellow eye had good visual acuity of 6/6-6/12 in 53.06%.In our study 64.29% of cases presented within seven days of onset of symptoms. Most patients underwent small incision cataract surgery with PCIOL implantation in the bag (88.77%). In our study good visual outcome of 6/6 to 6/12 was observed in 45.92% and poor visual outcome <6/60 was observed in 12.24% cases. When the age of the patient is compared between the groups of good and poor visual outcome there is a statistical significant correlation with the p value of 0.031.The best corrected visual acuity when compared with duration of symptoms the p value was found to be less than 0.01% which shows there is a strong statistical association between BCVA and duration of symptoms. CONCLUSION: The majority of patients had good vision in the other eye so neglected the affected eye and this resulted in the development of lens induced glaucoma. When the patients presented late after the development of the symptoms of lens induced glaucoma, the visual outcome is poor even after cataract surgery in some cases and hence patient education and screening for cataract is essential. Surgery is the definitive treatment in cases of lens induced glaucoma and the visual outcome after surgery is good when the patient presents early.
