Abstract
Diabetic macular edema is the most common cause of visual loss resulting from diabetic retinopathy. It poses a real challenge in its diagnosis and management owing to the high financial impact it has on health care systems worldwide.
The present study was conducted on a total of 30 eyes of 21 subjects who attended the ophthalmology department outpatient clinic at Alexandria Main University Hospital with aiming to compare between the three different imaging modalities FFA, OCT and OCTA in diagnosis of Diabetic Macular Edema regarding the appearance of macular edema, Foveal Avascular Zone and distribution of MAs related to macular edema.
All patients in this study were subjected to standard ophthalmological examination with emphasis on best corrected visual acuity (BCVA), anterior segment examination using slit lamp biomicroscope, fundus examination after full pupillary dilation and retinal imaging with FA using Topcon Retinal camera, OCT imaging using (Spectralis; Heidelberg Engineering, Heidelberg, Germany) and OCTA imaging using (Cirrus HD-OCT; Carl Zeiss Meditec, Dublin, CA, USA).
The age of the patients ranged from 40 years to 76 years at the time of diagnosis of diabetic macular edema. (mean, 55.77 years± 8.61).
On examining the eyes 43.3% (13 eyes) were on left side and 56.7% (17 eyes) were right side.
