Effect of nepafenac on the foveal profile of glaucomatous patients undergoing phacoemulsification.

PURPOSE: Retrospective, pilot study to determine whether nepafenac treatment pre- and postcataract surgery in glaucoma patients using topical hypotensive agents minimized cystoid macular edema by comparing pre- and postsurgical foveal characteristics, as in some cases these agents cannot be withdrawn and, hypothetically, their inflammatory effect on the fovea could be neutralized by the addition of nepafenac.

METHODS: Patients were divided into two subgroups depending on whether or not topical nepafenac was added to the surgical protocol (NEP = nepafenac group and nNEP = non nepafenac group). All had undergone phacoemulsification and data on pre- and postoperative macular status were recorded.

RESULTS: In the nNEP group, there was a significant increase in foveal thickness (FT) in the first month postoperative visit with respect to the preoperative status (p = 0.006), and this situation did not change at the third postoperative month (p = 0.9411). In the NEP group, the increase in FT was not significant at the first month after surgery (p = 0.056) nor at the final visit (p = 0.268), in contrast to the nNEP group.

CONCLUSION: This study of the possible prophylactic effect of nepafenac on postoperative macular edema supports the results of other studies that confirm subclinical edema post phacoemulsification, and found a significantly lower gradient in the increase in FT in patients treated pre- and postoperatively with nepafenac.
