[Combined occlusion of central retinal vein].

Combined occlusion of central retinal vein and cilioretinal artery represents 40% of all cilioretinal artery occlusions. Pathogenesis of this uncommon occlusion remains controversial. We present three cases id combined vascular occlusion that were diagnosed at our department from 2003 until 2008. Our patients, all productive age, had undergone complete clinical examinations and investigations to determine the cause of this condition. One patient had been diagnosed to have heterozygous form of protrombine mutation. Curious is also possible connection of vascular occlusion and application of anti-Hepatitis A and B vaccine.
