OCT Angiography of peripapillary retina in Primary Open Angle Glaucoma Patients

Background: Primary open-angle glaucoma is the world's second leading cause of irreversible blindness, and there are many ways for its assessment.Aim of the work: To show the importance of OCT Angiography for measuring the density of the radial peripapillary plexus in people who have primary open-angle glaucoma.Patients and Methods: As part of this case-control study, 30 eyes from 19 people with Primary open-angle glaucoma were used as group A. These eyes were split into three groups: mild, moderate, and serious Primary open-angle glaucoma patients. As group B, 30 eyes from 15 healthy controls were used . OCTA was done to both groups from June2023 to October 2023.The study was conducted at out patient clinics of Al-Azhar University Hospitals and Elmataria teaching hospital .Results: Ten men and nine women made up group A. Their average age was 56.75 years, with a standard deviation of 7.88 years. Group B had a mean age of 54.00 ± 9.63, with seven men and 8 women. The whole image density of the optic disc, the inside disc density, the peripapillary density, the hemiperipapillary density, and the nasal, inferior, temporal, and superior peripapillary densities all went down with the seriousness of the disease (p-value <0.001).Conclusion: The findings of this study indicate that quantitative OCTA can assist in the diagnosis of glaucoma by assessing the decrease in radial peripapillary capillary plexus density.
