Abstract
Purpose
To compare the choroidal thickness of a branch retinal vein occlusion (BRVO) lesion and that of other areas in the eyes.
Methods
Patients who visited the Ophthalmologic Clinic of Inje University Sanggye Paik Hospital for BRVO between March 2015 and October 2015 were reviewed retrospectively. We performed basic ophthalmologic exam and enhanced depth imaging optical coherence tomography in 48 eyes of 24 patients with BRVO. The choroidal thickness was compared in a total of 4 places, the branch retinal vein occlusion lesion, the symmetric site in the same eye, and the equivalent sites in the fellow eye by paired t-test. All measurements were performed by 2 independent observers.

Figure 1.
Method of measuring the choroidal thickness. Cross sectional image centered in macula (blue circle) was taken in the enhanced depth imaging mode with suprerior branch retinal vein occlusion (BRVO) in left eye. Black arrow points the lesion in BRVO. White arrow points the symmetrical site to lesion in BRVO. Black arrowhead points the equivalent site to lesion in fellow eye, and white arrowhead points the equivalent site of symmetrical site to lesion in fellow eye. Choroidal thickness was measured in 3 points (red circles) of each site. And the average choroidal thickness was calculated.
