| Abstract | ||
| Background: Optical coherence tomography angiography (OCTA) is a new safe imaging technique that uses motion contrast imaging to high-resolution volumetric blood stream information to produce angiographic pictures in a matter of seconds. Objectives: We aimed to identify different patterns and types of CNV by OCTA and the relationship between these patterns and activity of CNV. Patients and Methods: Fifty eyes of 50 patients presented with CNV had a regular diagnostic evaluation that included FA and/or OCT. Suspected cases with CNV underwent scanning by OCTA in this study. Patients with media opacity or bad image quality had been excluded. Results: In 80% of patients, there is a statistically significant correlation between the patterns of CNV and its activity (P-value =0.0001). Conclusion: OCTA is a critical technique for better characterizing the various forms and patterns of CNV, as well as the link between these patterns and CNV activity. | ||
