Unfortunately, RVO is a potent blinding disease having a prevalence of " ~ " 0.5 percent. It’s the 2nd commonest vascular retinal disease following DR.
Recent investigation tools in CRVO include FA and OCT. OCTA is the novel emergent approach to assess retinal vasculature without using a fluorescein dye. OCTA depends on the use of the moving RBCs within the retinal vasculature and put them into Algorism generating a 3D multi-layered retinal vasculature imaging.
This study aimed to correlate findings of OCTA, OCT and FA in cases suffering CRVO. This was a cross sectional study, including 20 eyes of 20 patients with CRVO detected by retinal specialist; each case was investigated by Topcon FA camera, Zeiss Cirrus 6000 HD OCT and Zeiss Angioplex OCT Angiography. Any case suffering other systemic or retinal diseases or previous retinal surgeries was excluded. Two retina specialists were asked to evaluate blindly the FA, OCT and OCTA images.
FAZ assessment in FA, OCTA at level of SCP in CRVO revealed excellent agreement, whereas in between FA and OCTA at level of DCP exhibited poor agreement. This was because earlier involvement of ischemia in DRL and presence of eodema.
OCTA measurements of PD and VD were compared to measurements in normal people, The difference in full VD & PD were statistically significant. There was a significant reduction in full VD & PD in cases of CRVO compared to group of normal people within the same age group.
In this study, we also used Image J for FAZ measurement in comparison with Zeiss software; results were nearl
