A STUDY ON INCIDENCE OF ACUTE INTRAOCULAR PRESSURE ELEVATION IN DIABETIC PATIENTS TREATED WITH LASER PHOTOCOAGULATION IN TERTIARY CARE HOSPITAL.
Abstract
AIM: This study was undertaken to determine the acute changes in IOP following laser photocoagulation used in the treatment of diabetic retinopathy.
METHODS AND METHODOLOGY: This study was conducted at the Department of Ophthalmology, Chalmeda Ananda Rao Institute Of Medical Sciences from July 2017 to June 2018 . This study was intended to see the onset and duration of intraocular pressure spikes in diabetic retinopathy patients after green laser photocoagulation.
RESULTS: Out of 45 patients, 6 patients had severe non proliferative diabetic retinopathy with maculopathy, 39 having proliferative DR. Out of 6 NPDR patients, 3 (50%) developed immediate post laser angle closure (Schaffer's grade 1) which persisted for 3 days and other 3 had shown no change in angle structure. Out of 39 PDR patients, 12(30.7%) had post laser angle closure.These results are clinically and statistically significant.Overall 33.33% of patients showed raised intraocular pressure following PRP.
CONCLUSION:The present study clearly shows that after extensive laser photocoagulation in diabetic retinopathy patients, elevation in IOP may appear immediately or 1-2 hours or 1-2 days later and this last for 2-3 days
