| Aim: To determine specificity and sensitivity of OCT-A in detecting choroidal neovascular lesions (CNV) in eyes with suspected nAMD. Setting: Al Mashreq Eye Center, in the period between Jul-2021 to Nov-2021. Methods: A prospective, comparative study included 44 eyes to assess accuracy of OCT-A in the detection of nAMD compared to conventional OCT. Eyes were divided into a study group with nAMD, and a control group with dry AMD. OCT of the central macula was conducted, followed by OCT-A. Results: This study was performed on 25 patients with a mean age of 69.88 ± 8.31 years. The mean BCVA was 0.45 (± 0.31), and that of SE was 0.16 (± 1.52). IOP had a mean of 15.39 (± 3.08). According to SD-OCT criteria; 24 eyes (54.5%) were diagnosed as dry AMD, and 20 eyes (45.5%) with nAMD. Cases of nAMD were subdivided into type-1 (70%), and type-2 (30%). For eyes with type 1, 8 cases (57.1%) had an associated fibrovascular PED. Using OCT-A, 28 eyes were classified as dry AMD, and 16 eyes with nAMD that were differentiated into: Type-1 (6-cases), Type-1 with PED (5-cases) and Type-2 (5-cases). There was no statistically significant difference between OCT and OCT-A regarding percentage of positive cases (p=0.386), and their finding of type-1, type-1 with PED, and type-2 (p=1.000). Conclusion: There was a statistically significant relation in classification agreement between SD-OCT and OCT-A findings (p < /p> | ||
