Evaluation of choroidal vascular structure in patients with retinal vein occlusion
Abstract
Aims: To evaluate the posterior segment structures and choroidal vascularity of the eye in patients with retinal vein occlusion (RVO) using enhanced depth imaging optical coherence tomography (Edi-OCT).
Methods: Twenty-nine treatment-naïve patients with RVO (17 males, 12 females) were examined by EDI-OCT. Subfoveal choroid tickness and choroidal vascularity index (CVI) were used to compare the structural characteristics of the choroid with the eyes of twenty-nine age, and gender-matched controls. EDI-OCT images were binarised using ImageJ program.
Results: Best corrected visual acuity was significantly lower in the affected eyes compared to control group (p=<0.001). Central macular thickness, subfoveal choroidal thickness, choroid stromal area, and total choroid area were found to be significantly higher in the patient group (p=<0.05). CVI was significantly lower in the patient group and no significant difference was found between the groups in terms of intraocular pressure values (p>0.05).
Conclusion: RVO causes significant edema in the choroid stromal area without any change in the choroid lumen area. This structural changes in the choroid evaluated by EDI-OCT, a non-invasive examination, may be used in the diagnosis and follow-up of RVO.
