ABSTRACT
Objective To assess the consistency of diagnostic results using optical coherence tomography angiography (OCTA) and fundus fluorescein angiography (FFA) in the central retinal vein occlusion (CRVO).Methods This is a retrospective case series of 26 eyes of 26 patients with CRVO.There were 10 females (10 eyes) and 16 males (16 eyes).The mean age was (49.19±10.50) years.The mean course of the disease was (27.81± 21.60) days.Simultaneous OCTA and FFA were performed in all patients using 7-standard field of Early Treatment Diabetic Retinopathy Study (ETDRS) to evaluate the microaneurysms,nonperfused areas,optical disc/retinal neovascularization and maeular edema.The consistency was evaluated using weighted Kappa statistic values.Kappa≥0.76,consistency is excellent;0.60≤Kappa<0.75,consistency is good;0.40≤Kappa<0.60,consistency is general;Kappa<0.40,consistency is poor.Results Based on OCTA,microaneurysms were found in 23 eyes,nonperfused areas in 16 eyes,optical disc/retinal neovascularization in 8 eyes and macular edema in 21 eyes.Based on FFA,23 eyes were diagnosed to have microaneurysms,14 eyes have nonperfused area,8 eyes have optical disc/retinal neovascularization,22 eyes have macular edema.The consistency was excellent for microaneurysms and optical disc/retinal neovascularization (Kappa=0.772,0.766;P<0.01),good for nonperfused areas and macular edema (Kappa =0.703,0.600,P< 0v01).Conclusion There is high consistency between OCTA and FFA in the diagnosis of microaneurysms,macular edema,nonperfused areas and optical disc/retinal neovascularization in CRVO patients.
