Screening For Diabetic Macular Edema Among Diabetic Patients Using Optical Coherence Tomography

Screening For Diabetic Macular Edema Among Diabetic Patients In Assiut University Hospital Using Optical Coherence Tomography

Diabetic macular edema is one of the major causes of visual impairment in diabetic retinopathy patients especially in the working age group. The problem is likely to increase in the future with statistics showing a growing number of the diabetic population especially in the Middle East . .

The worldwide prevalence of diabetic macular edema was reported as 6.81% among patients with diabetes. Other research reported that the 10-year incidence of diabetic macular edema was 14% in individuals with type 2 diabetes, and progression to diabetic macular edema occurred in 29% of individuals with type 1 diabetes over 25 years if left untreated . Although diabetic macular edema resolves spontaneously in about 33% to 35% of patients, it tends to be chronic in most patients..Diabetic macular edema can occur at any stage of diabetic retinopathy . The symptoms of diabetic macular range from slight visual blurring to complete blindness if left untreated . Optical coherence tomography is an objective non-invasive method for high-resolution cross-sectional imaging of the retina .

Inclusion Criteria:
