Zusammenfassung:Background Optical coherence tomography angiography (OCTA) is a sophisticated ophthalmic imaging technique, enables us to obtain images of blood vessels and blood flow at different levels of the retina and choroid without the use of contrast. Therefore, its potential application could be useful in the early detection of retinal vascular and macular pathologies and to recognize the pathogenesis of various ophthalmic diseases. Aim In this study, OCTA was utilized to detect the macular changes in eyes with high myopia. Patients and methods This cross-sectional study was carried out at the Department of Ophthalmology of Menoufia University Hospital according to the Helsinki Declaration and the Code of Ethics for Human Research of the World Medical Association and after obtaining approval of the institutional review board (IRB) 10/2022 OPHT 32. A total of 152 eyes of the study participants were included in this study and were divided into group A, which includes 76 eyes of highly myopic participants (>-6 D), and group B includes 76 eyes of nonmyopic (emmetropic) participants. Result In our study, there was a high statistically significant difference between the studied groups as regards axial length. In group A, it was 27.26±0.74 mm, while in group B, it was 23.14±0.73 mm (P
