Abstract
ABSTRACTAims: To outline the different characteristics of glaucomas and to determine the risk factors and their consequences on postoperative visual acuity, intraocular pressure (IOP), and inflammation, including corneal changes and optic disk changes.Settings and designs: Longitudinal prospective study done over a period of 1.5 years in a medical college hospital.Materials and methods: Fifty patients of lens-induced glaucoma (LIG) were included. At presentation, visual acuity, IOP, and inflammation, including corneal changes, were recorded. After medical line of treatment, postoperatively patients were followed up regularly at 2 and 7 weeks interval and the same parameters were evaluated including optic disk changes.Statistical analysis used: Paired t-test, chi-square test wherever applicable with p-value < 0.05 as significant.Results: The mean age of presentation was 60.68 years with female to male ratio of 1.7:1. The best corrected visual acuity(BCVA) of 6/18 or more was found in 54% cases, whereas visual acuity of less than 6/60 was seen in 26% of cases. Visual acuity of 6/12 or better was achieved in 72% (p < 0.01) of cases with symptoms less than 2 weeks and in 59.10% of cases with IOP of less than 35 mm Hg at presentation. The mean IOP in cases with duration of symptoms of 2 to 4 weeks was 40.33 ± 9.36 mm Hg. Optic disk of the affected eye suffered damage in 42% of cases and in 80% of cases with symptoms for more than 2 weeks.Conclusion: Early diagnosis and treatment is beneficial in LIG cases.How to cite this article: Sharanabasamma M, Vaibhav K.

Summary
In India, 62.6% blindness is due to cataract.[1] Lens-induced glaucoma (LIG) is common in India.[2] It is a common condition seen in patients with senile cataracts and is one of the commonest cause of secondary glaucoma, requiring an immediate attention and management to prevent blindness. These are heterogeneous group of disorders which develop through either open-angle or angle-closure mechanisms.[3] Phacolytic glaucoma (PLG) and lens particle glaucoma are types of secondary open-angle glaucomas. Phacoanaphylactic uveitis, termed as lens-induced uveitis, is not truly an anaphylactic reaction but is a granulomatous reaction that can cause open-angle or angle-closure glaucoma or combined open-angle and angle-closure glaucoma.[4]
