Macular thickness measurement in clinically significant macular edema before and after meal

To evaluate the macular thickness changes in diabetic macular edema after meal.
In this prospective case series, macular thicknesses of diabetic patients with clinically significant macular edema (CSME) were measured after 7 h of fasting and repeated 2 h after breakfast.
Thirty six eyes of 20 diabetic patients were evaluated. The mean central subfield thickness (CST) and maximum retinal thickness (MRT) significantly decreased after meal (mean change of
10.3 ± 14.3 mm and
13.1 ± 12.7 mm, respectively, both P Retinal thickness measurements may change after meal. So, fasting state of diabetic patient should be considered in measurement of macular thickness of patients with CSME.
