Purpose:
To compare standard and frequent topical steroids for postsurgical macular edema (ME).
Design:
Randomized clinical trial.
Methods:
Subjects with postsurgical ME stratified into post-cataract surgery ME (PCSME) and post-other surgery ME (POSME) were randomized to ketorolac 4 times a day (qid) + 1% prednisolone acetate (PA) every hour while awake (q1hWA, Group 1) or qid (Group 2). Mean change from baseline best-corrected visual acuity (BCVA) was determined at week 12, after which group 2 subjects with persistent edema were crossed over to PA q1hWA.
Results:
Twenty-two subjects (13 PCSME and 9 POSME) were randomized to Group 1 and 20 (12 PCSME and 8 POSME) to Group 2. At week 12, change from baseline BCVA (ETDRS letters) in Group 1 vs 2 was +11.6 vs +8.5 (P = .32) and for subgroups was +10.6 vs +7.8 (P = .23) for PCSME and +13.1 vs +9.4 (P = .47) for POSME. Mean change from baseline central subfield thickness (CST, μm) at week 12 in Group 1 vs 2 was -100.8 vs -63.9 (P = .30). Mean change from baseline intraocular pressure was +2.6 vs +1.7 mm Hg (P = .52). Eight subjects in Group 2 with residual ME at week 12 were switched to PA q1hWA and at week 24, the mean changes from week 12 BCVA and CST were +7.0 letters (P = .01) and -108.25 μm (P = .04).
Conclusions:
Our data suggest that patients with postsurgical ME should initially be treated with ketorolac and PA qid, but if edema does not resolve after 12 weeks, a switch to ketorolac qid and PA q1hWA may provide benefit.
