The purpose of this article is to report a case in which a double hemispheric retinal vein occlusion (HSRVO) occurred in the same eye, involving firstly the superior half and later the inferior half of the retina. A 63-year-old woman with ill-controlled hypertension had been diagnosed with central retinal vein occlusion in the right eye in January 1998. The patient had a HSRVO of the superior hemiretina in November 2003, and a HSRVO of the inferior hemiretina in August 2005. The patient underwent a complete work-up, but the only detected risk factor was hypertension. Bearing in mind the absence of an effective treatment able to reduce both the incidence and the recurrence of retinal vein occlusion, detection and control of the risk factors, such as hypertension, is essential. We should make every effort to improve the compliance of our patients in controlling general diseases all their lives.
