Purpose:
|
To evaluate the retinal thickness changes in normal eyes and in diabetic macular edema after meal.
|
|
Methods:
|
In this prospective nonrandomized study, retinal thickness of diabetic patients with clinically significant macular edema (CSME) and normal subjects were measured after 7 hours of fasting and repeated 2 hours after breakfast.
|
|
Results:
|
Thirty six eyes of 20 diabetic patients and 38 eyes of 19 normal subjects were evaluated. In normal subjects, the mean central subfield thickness (CST) and maximum retinal thickness (MRT) measurements were statistically similar before and after meal (both P=0.9). In diabetic eyes, the mean CST and MRT significantly decreased after meal (mean change of -10.3±14.3 µm and -13.1±12.7 µm, respectively, P<0.001). A decrease in CST and MRT values was found in 23 (63.8%) and 28 (77.7%) eyes, respectively, and no eye had an increase in retinal thickness measurements. Significant correlation was found between CST and MRT change and fasting thickness measurements (P=0.001 and P=0.01, respectively) and intraretinal cystic spaces (P=0.001 and P=0.03, respectively). Mean MRT change was significantly higher in the presence of subretinal fluid (P=0.01).

|
Conclusion:
|
Retinal thickness changes after meal should be considered in the management of the patients with CSME.
