Abstract:

Objective To estimate the ability of OCTA in detecting choroiodal neovascularization (CNV) secondary to pathologic myopia and to assess the ability of OCTA in assessment of the activity of CNV compared to fundus fluorescein angiography (FFA). Design Diagnostic method evaluation. Participants 40 eyes with clinical diagnosis of CNV secondary to pathologic myopia in Beijing Tongren Eye Center. Methods All the eyes underwent FFA and OCTA respectively. The diagnosis of CNV and the judgment of CNV activity were compared between FFA and OCTA. Main Outcome Measures The sensitivity and specificity of OCTA, and Kappa value. Results The sensitivity and specificity of OCTA for choroidal neovascularization secondary to pathologic myopia were 96.7% and 100% respectively. The agreement for grading of CNV activity between OCTA and FFA was moderate (Kappa=0.502, P<0.001). Conclusion  OCTA demonstrate high sensitivity and specificity for detection of CNV secondary to pathological myopia, while with a moderate ability of grading CNV activity.
