Mortality in Patients with Branch Retinal Vein Occlusion

In this study of 329 patients with BRVO, we found no significant difference in mortality between patients and the background population. An association between BRVO and cardiovascular/cerebrovascular risk factors has previously been documented in cross-sectional studies. The contrasting outcome in this longitudinal study may have been influenced by interventions instituted after the diagnosis of BRVO was made and by preferential survival before the diagnosis of BRVO of the more fit patients with the necessary precursor condition of having arteriovenous nicking, which is more prevalent in subjects with diabetes and hypertension.
