Visual acuities (VA) at baseline and final visit were recorded. Foveal thickness, based on optical coherence tomography, was also recorded.Results: Six eyes of 5 patients were included in this study. Median initial Snellen vision was 20/100 (range, 20/40–20/400). After a mean of 210 days (range, 182–259), median final VA was 20/75 (range, 20/40–20/400). Four eyes gained vision and two eyes maintained vision. Mean pre-treatment vision was 0.78 logMAR and final VA was 0.67 logMAR, for a statistically significant improvement (p < 0.05). Mean initial foveal thickness was 417 microns (range, 286–599). After a mean of 178 days (range, 91–259), mean foveal thickness was 267 microns (range, 158–423), showing a statistically significant improvement (p < 0.05). Each eye had an improvement in foveal thickness.Conclusion: The results from these 6 eyes suggest that nepafenac 0.1% may have activity against diabetic macular edema and warrants further investigation.Keywords: diabetes, diabetic macular edema, inflammation, macular edema, nepafenac, NSAID
