Optical Coherence Tomography Angiography (OCTA) information content in the diagnosis of type 1 choroidal neovascularization combined with pigment epithelium detachment

Purpose of the study is to determine the reliability of OCT angiography in the diagnosis of type 1 choroidal neovascularization (CNV) in wet age-related macular degeneration depending on the height of pigment epithelium detachment (PED).Material and methods. The study included 82 patients (114 eyes)...

description Purpose of the study is to determine the reliability of OCT angiography in the diagnosis of type 1 choroidal neovascularization (CNV) in wet age-related macular degeneration depending on the height of pigment epithelium detachment (PED).Material and methods. The study included 82 patients (114 eyes) with confirmed type 1 CNV, who were examined using spectral OCT and OCTA. The patients were divided into two groups depending on PED height: group 1 consisted of 69 eyes with PED height less than 300 μm, while group 2 (45 eyes) had PED height of more than 300 μm. A separate comparative analysis of the visualization of pathological vessels was made in a group of untreated patients (56 eyes) and a group of patients (58 eyes) treated with angiogenesis inhibitors.Results. In group 1 with a PED height less than 300 μm (167.0 ± 60.4 μm) OCTA detected blood flow along abnormal vessels in 100 % of cases. In group 2 with a PED height above 300 μm (484.7 ± 131.9 μm) CNV vessels were visualized in 24.4 % of eyes. The PED height of patients after intravitreal injections of angiogenesis inhibitors (IVI IA) ranged from 38 to 683 μm (221 ± 133 μm). According to OCTA visualization of type 1 CNV vasculature was noted in 55 eyes (94.8 %). In patients who received no antiangiogenic therapy, with a PED height 59 - 800 μm (238 ± 149 μm) CNV was visualized in 41 % of cases (23 eyes).Conclusion. OCTA showed high reliability in the diagnosis of type 1 CNV with low PED. This method was significantly less informative when the height of the neovascular PED exceeded 300 μm, with the exception of PED after IVI IA.
