Abstract
BACKGROUND: Compared to steroids non-steroidal anti-inflammatory drugs offer comparable anti-inflammatory action without ocular side-effects. AIM: To compare the anti-inflammatory effect and effect on IOP (Goldmann) of topical diclofenac 0.1% with dexamethasone 0.1% after strabismus surgery. DESIGN: Prospective, randomized, double-blind, single-center, clinical trial. MATERIALS AND METHODS:Forty-three cases of constant horizontal strabismus, qualifying for standard uniocular recession-resection surgery on two horizontal rectus muscles were randomized to either the dexamethasone or diclofenac group. They were excluded if they had previous ocular surgery, recently used anti-inflammatory drugs and had a neurological, systemic or an ocular inflammatory condition. In addition all received ciprofloxacin 0.3% four times daily. Assessment was done on the first postoperative day and at two and four weeks. The inflammatory characteristics graded from nil (0) to severe (3) were: discomfort, chemosis, injection, discharge and drop-intolerance. Their sum provided the total inflammatory score (TIS). RESULTS:Dexamethasone group (n=21) was comparable in age, gender, preoperative IOP, strabismus, anesthesia administered and baseline IOP, to diclofenac (n=22). There were no significant differences in the inflammatory characteristics and TIS. The dexamethasone group had IOP significantly higher at two weeks (95% CI 0.17 to 3.25) and four weeks (95% CI 1.09 to 4.24) compared to diclofenac group and the net change of IOP at four weeks (95% CI 0.60 to 3.14). Compared to the baseline IOP. CONCLUSION:Topical diclofenac is comparable to dexamethasone in providing anti-inflammatory and analgesic effect with the advantage of significantly lesser IOP rise and should be preferred after strabismus surgery.
