Abstract

Aim: To study IOP changes in patients undergoing PRP for PDR.

Method: 60 eyes with PDR, in our prospective, observational study. After assessment of vision, IOP, fundus & gonioscopy, patients were treated with PRP. After PRP, IOP recorded at 30 minutes, 1-hour & 2-hours. Gonioscopy & IOP recordings done on Day 1,1-week,1-month & 3-months post-PRP.

Results: Mean IOP (mm Hg) at 30 minutes, 1-hour, 2-hours, 1-day, 1-week, 1-month & 3-months post-PRP were 14.5 ± 3.2, 18.03 ± 2.89, 18.5 ± 2.26, 17.93 ± 2.52, 15.53 ± 2.61, 14.9 ± 2.59, 14.7 ± 2.52 & 14.63 ± 2.69 respectively. Significant increase (p<0.05) at 30 minutes,1-hour,2-hours & 1-day compared to pre-PRP IOP noted. Subsequent post-PRP IOP was not significantly different. Conclusion: An initial transient rise in IOP was noted for few hours post-PRP. This increase in IOP, if significant can cause glaucomatous change over a long period.
