| Abstract | ||
| Background: to date, fundus fluorescein angiography (FFA), remains the gold standard for the diagnosis of choroidal neovascular membrane (CNV). Optical coherence tomography angiography (OCTA) is a new imaging modality that allows a clear, depth-resolved visualization of the retinal vascular structures. Aim of the Work: to evaluate the role of OCTA in diagnosis of CNV in patients with age-related macular degeneration (AMD). Patients and Methods: this study enrolled 32 patients (40 eyes), including 20 patients (20 eyes) with wet AMD and 12 patients (20 eyes) with dry AMD. All patients underwent swept-source optical coherence tomography (SS-OCT), swept-source OCTA, and fundus fluorescein angiography (FFA). OCTA was used to evaluate neovascular networks in terms of their type, location and extent of visualization. Sensitivity and specificity of the method were assessed separately in a group of 20 CNV eyes and 20 dry AMD based on FFA diagnosis as the gold standard. Results: sensitivity and specificity of en face OCTA were 95% and 100% respectively. Both Sensitivity and specificity of structural OCT were 100%. Conclusion: OCTA enables diagnosis of both classic and occult choroidal neovascularization in patients with AMD. The method has high sensitivity and specificity. | ||
