Abstract

Background: Withoptical coherence tomography angiography (OCTA), blood circulation in the retina and choroid may be examined non-invasively by means of motion contrast imaging.
Objective: This study aimed to investigate the usage of OCTA to look at how the blood vessels in the retina of diabetic patients are changed before and after phacoemulsification that didn't go wrong.
Methods: This controlled prospective not randomized study was conducted through the period from February 2021 to February 2022 in Al-Azhar University hospital.
Results: All of the OCTA measurements of the microvasculature were done before, and after one week, one month, and three months following phacoemulsification for cataract. After three months, the average macula thickness (MT) was 329.68 ± 24.56 micrometer, up from 275.48 ± 14.93 micrometer at the start of the research. The SCP% increased significantly from 40.28 ± 1.09 at baseline to 42.34 ± 1.44 at one-month post-operative, to 43.59 ± 1.72 at 3 months post-operative (P< 0.05). This rise was statistically significant (P < 0.05).
Conclusion: According to the findings of our research, OCTA helped to diagnose and keep track of DM patients with early diabetic retinopathy (DR). It gave detailed images and data about microvascular changes in the retinal layers that could not be seen with other investigation tools.
