Objective:

To identify the proportion of eyes with recurrence of diabetic macular edema, six months after focal photocoagulation.

Method:

Non-experimental, analytical, cross-sectional and prospective study in patients with diabetic macular edema treated with focal photocoagulation. The proportion and 95% confidence intervals (95% CI) of eyes with recurrence of edema were identified; the distribution of anatomical variables and visual acuity was compared between eyes with and without recurrence, using Mann-Whitney's U.

Results:

145 eyes were evaluated, and only 10 (95%CI: 2.8-11) had a recurrence. Center point thickness and center field thickness means were higher in eyes with recurrence than in eyes without it, but the difference of change mean betwwen groups was not statistically significant.

Conclusion:

The proportion of recurrent diabetic macular edema recurrence six months after successful focal photocoagulation was lower than the one reported for other treatments of diabetic macular edema, and by recent studies that used photocoagulation.
