PURPOSE: To evaluate and compare the clinical and angiographic characteristics of retinal vein occlusion (RVO) in glaucomatous and non-glaucomatous eyes with unilateral RVO in the fellow eye. METHODS: Twenty-one glaucomatous eyes (GL group) and 25 age-matched non-glaucomatous eyes (non-GL group) with unilateral RVO in the fellow eye were included in this study. Fluorescein angiographic images were assessed in both groups by 3 retina specialists in order to determine the RVO occlusion site. The occlusion site was divided into 2 types: arteriovenous (AV)-crossing and non-AV-crossing (optic cup or optic nerve sited). The clinical characteristics and prevalence of AV-crossing and non-AV-crossing RVO were compared between the 2 groups. RESULTS: The mean baseline intraocular pressures of the RVO eye and the fellow eye did not differ between the 2 groups (RVO eye: 14.3 ± 2.5 mmHg [non-GL group], 15.5 ± 3.9 mmHg [GL group], p = 0.217; fellow eye: 14.4 ± 2.5 mmHg [non-GL group], 15.7 ± 3.7 mmHg [GL group], p = 0.148). The prevalence of systemic disease did not differ between the 2 groups (e.g., diabetes mellitus and hypertension, p = 0.802 and 0.873, respectively). AV-crossing RVO was significantly more frequent in the non-GL group (19 eyes; 76%) than in the GL group (4 eyes, 19%, p < 0.001). CONCLUSIONS: Non-AV-crossing RVO, i.e., optic cup- or optic nerve-sited RVO, is more frequently associated with glaucomatous changes in the fellow eye. Therefore, this type of RVO should be monitored more carefully for indications of glaucoma in the fellow eye.
