Optical coherence tomography (OCT) is a new imaging technique,
which can provide cross sectional images of the retina with high
resolution. The aim of this work is to compare OCT versus fundus
fluorescein angiography (WA) in cases of branch retinal vein occlusion.
Fifteen eyes of fifteen patients having unilateral branch retinal vein
occlusions were selected. OCT and WA were performed to all cases and
findings in both techniques were compared.
In both FFA and OCT, four eyes had no cystoid macular edema or sub
retinal fluid while six eyes showed cystoid macular edema-Three eyes
showed small cystic spaces in OCT which could not be detected with
WA. Subretinal fluid was observed in OCT but not in FFA in five eyes.
Three of these eyes had both cystoid macular edema and subretinal fluid
while two eyes showed subretthal fluid alone .
This work showed that OCT was superior to FFA in detecting small
intraretinal cystic spaces and subretinal fluid in cases of branch retinal
vein occlusion. |
