The course of response to focal/grid photocoagulation for diabetic macular edema.

ABSTRACT:

Purpose

The purpose of this study was to determine whether eyes with center-involved diabetic macular edema, treated with focal/grid photocoagulation, in which there is a reduction in central subfield thickness (CST) measured with optical coherence tomography after 16 weeks, will continue to improve if retreatment is deferred.

Methods

This is a prospective, multicenter, observational, single-group focal/grid photocoagulation study of 122 eyes with center-involved diabetic macular edema (optical coherence tomography CST > or =250 microm). At the 16-week visit and continuing every 8 weeks, eyes were assessed for retreatment and additional laser treatment was deferred if the visual acuity letter score improved > or =5 letters or optical coherence tomography CST decreased > or =
