Primary Outcome Measures:
  • ocular topic antiinflammatory therapy (ketorolac, nepafenac or placebo) applied 3 times a day in the treated eye for a week after selective photocoagulation [ Time Frame: one week after treatment ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • center point thickness using stratus OCT measured in microns [ Time Frame: before treatment, at 24, 48 and 168 hours after treatment ] [ Designated as safety issue: No ]
  • macular volume using stratus OCT measured in cubic millimeters [ Time Frame: before treatment, 24, 48 and 168 hours after treatment ] [ Designated as safety issue: No ]
  • visual capacity under subjective refractive correction measured in decimal equivalent [ Time Frame: before treatment, at 24, 48, 168 hours after treatment ] [ Designated as safety issue: No ]

Estimated Enrollment: 84

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.
