Lens induced glaucoma – Clinical profile and prognosis in tertiary care centre

Abstract

Conditions in which cataractous lens and abnormalities of lens leads to elevated intra ocular pressure have been termed as Lens induced glaucoma (LIG). Objective of our study was to know the clinical profile of patients, describe management and visual outcome in lens induced glaucoma. Hospital based prospective study conducted on 40 patients of LIG from November 2016 to October 2018 attending the outpatient department of Ophthalmology at Minto Ophthalmic Hospital, Bangalore Medical College and Research Institute. After taking informed consent, detail history, detailed examination, IOP by Applanation tonometry, Gonioscopy, examination of posterior segment, patients diagnosed as lens induced glaucoma admitted and managed with medical and surgical treatment. Post operative day 1 visual acuity and IOP recorded and followed up on day 8 and 6 weeks for above. Data analyzed with descriptive statistics and chi square test. In our study mean age of presentation in phacomorphic glaucoma is 67.25 ± 6.58 years and phacolytic glaucoma mean age was 64.10years ± 9.78. Female to male ratio being 1.8 : 1. Phacomorphic glaucoma was found in 57% and phacolytic glaucoma in 43%. Mean IOP at presentation was 42.6mmHg ±5.36. Most of them underwent SICS + PCIOL (52.5%). Study showed that most of them had better visual acuity at the end of 6 weeks. Final IOP was 15.8 mmHg± 1.78.Our study demonstrated that lens induced glaucoma is still a challenging complication of cataract which can be prevented by early treatment of cataract. SICS is still gold standard that effectively controls IOP and gives better visual outcome.
