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. RESULTS: Choroidal thickness had strong inter-observer correlation. Choroidal thickness of the BRVO lesion was significantly thicker than that in the symmetric site of same eye, the equivalent site of lesion, and the equivalent site of the symmetric site to lesion in the fellow eye. CONCLUSIONS: Choroidal thickness in acute BRVO lesions was thicker than choroidal thickness in other areas of the eyes. It is thought that both hydrostatic pressure and the effects of vascular endothelial growth factor influence choroidal thickness in the acute phase of BRVO.
Key Words: Branch retinal vein occlusion;Choroidal thickness;Spectral domain-optical coherence tomography (SD-OCT)
