Abstract
Purpose:
This study is done to evaluate diabetic macular edema using optical
coherence tomography angiography & compare it with the findings of fundus
fluresceine angiography
Patients & Methods:
This prospective, non-interventional study that was done on 34 eyes of 30
patients with Diabetic Macular Edema (DME). we captured images using Optical
Coherence Tomography Angiography (OCTA) using AgioPLEX with capturing
images of the FAZ area of each eye on the level of Superficial & deep capillary
layers .OCTA scan patterns of 3 mm × 3 mm and 6 × 6 mm centered at the macula
were performed comparing with FA images which are aligned to the OCTA
images using retinal vascular landmarks and cropped to the corresponding
dimensions (3 mm × 3 mm or 6 mm × 6 mm) to facilitate comparison and analysis.
The studied eyes were classified according to severity of macular oedema into Five
groups: Focal,Diffuse spongy,Diffuse cystoid,Mixed and Ischemic
Results:
Our results showed among 30patients 10 of them are males & 20 of
them are females.
Comparison between S OCTA & D OCTA in FAZ area showed no
statistical significance, while the comparison between FA & S OCTA
Summary & Conclusion
81
showed only a statistical significance difference within the ischemic
group (p=0.023).
With regard to micro aneurysmal count, the comparison between S
OCTA & D OCTA hadn`t any statistical significance difference,
however the comparison between FA & S OCTA had statistical
significance difference within the focal group (p=0.003).
In Conclusion:
OCTA is better in evaluation of FAZ area measurement than FA
in DME,while FA is better in microaneurysm counting than OCTA .
