N/A Macular edema caused by diabetes. Intervention 1: First group: patients undergo macular laser treatment without OCT-A. Laser specifications include yellow wavelength duration: 0.1 and power between 80 to 150 and spot size 50 micrometers, which is done at intervals of one spot in edematous areas. The goal is to change the color light to light gray in the laser areas. Intervention 2: Second group: After performing the OCT-A and locating the microaneurysms, laser therapy is performed. In this group, we use the yellow wavelength with duration: 0.1 and spot size: 50 micrometers with an intensity between 80 and 150 in the areas of microaneurysms. Light gray is present at the site of microaneurysms. Patients are followed up three times after the laser, at two-month intervals, including BCVA measurements and OCT. After collecting the data, they are analyzed and statistically analyzed.
