The purpose of this study is to determine the efficacy of ocular topic antiinflammatory therapy (sodic nepafenac at 0. 1% or ketorolac at 0. 5%) to treat center point thickness secondary to selective photocoagulation in diabetics with clinically significant macular edema.

Clinical Details

Official title: Efficacy of Topic Antiinflammatory Therapy Treatment in Center Point Thickness Secondary to Selective Photocoagulation in Diabetic Macular Edema

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver), Primary Purpose: Treatment

Primary outcome: ocular topic antiinflammatory therapy (ketorolac, nepafenac or placebo) applied 3 times a day in the treated eye for a week after selective photocoagulation

Secondary outcome:

center point thickness using stratus OCT measured in microns

macular volume using stratus OCT measured in cubic millimeters

visual capacity under subjective refractive correction measured in decimal equivalent

Detailed description: Selective photocoagulation is the standard treatment for clinically significant macular edema. This treatment decreased the incidence of moderate visual loss in the long term. Nonetheless, in the first six weeks after treatment it is induced, probably because an exacerbation of macular edema secondary to treatment. An inflammatory response has been reported after selective photocoagulation. Therefore, antiinflammatory therapy like ketorolac or nepafenac could be useful to manage center point thickness secondary to selective photocoagulation in diabetics with macular edema.
