    Abstract:
    PURPOSE: To evaluate the agreement between multimodal imaging-MI (fluorescein angiography, indocyanine green angiography, optical coherence tomography) and optical coherence tomography angiography (OCTA) in the detection of choroidal neovascularization (CNV) in patients with pigment epithelial detachment with subretinal/intraretinal fluid (PED+F) compared to patients with PED without subretinal/intraretinal fluid (PED-F). METHODS: Twenty-two eyes of 15 patients were divided into two groups (PED+F and PED-F). All patients underwent MI and OCTA with manual and automatic segmentation. MI findings were compared to OCTA findings and then analysed. RESULTS: In the PED+F group (10 eyes), all studied eyes demonstrated CNV in MI. In manual segmentation OCTA assessment, 9 of 10 eyes (90%) were detected with CNV. When evaluated by automatic segmentation, 8 of 10 eyes (80%) revealed the presence of CNV. In the PED-F (12 eyes) group, all eyes did not demonstrate CNV in MI and OCTA evaluations, either by manual or automatic segmentation. The agreement between MI and OCTA shows concordance (k: 0.908; 95% CI, 0.491-1.000); the evaluation of the agreement between the automatic and manual segmentation also shows concordance (k: 0.904; 95% CI, 0.488-1.000). CONCLUSION: The solid agreement between the multimodal imaging regarding the ability of OCTA to identify possible initial CNV in a patient with PED-F was observed. Accuracy was 95.45%. In addition, the agreement between manual and automatic segmentation to identify CNV on OCTA was also shown.
