Combined Branch Retinal Artery and Central Retinal Vein Obstruction

Simultaneous central retinal vein and retinal artery branch occlusions in two patients with homocystinaemia

“…[1][2][3][4][5] Branch retinal artery obstruction is again a rare event, even less common than central retinal artery obstruction overall. Branch retinal artery obstruction is, however, more prevalent than central retinal artery obstruction in young patients as our cases.…”

“…2,12 Simultaneous occlusion of the central retinal vein and central retinal artery or a cilioretinal artery are well-defined clinical entities. [1][2][3]12 Although they share many common underlying associations, simultaneous occlusion of central retinal vein and branch retinal artery obstruction is a rarely described occurrence. [1][2][3]12 The largest group of patients reported in the literature was of seven cases.…”

“…[1][2][3]12 Although they share many common underlying associations, simultaneous occlusion of central retinal vein and branch retinal artery obstruction is a rarely described occurrence. [1][2][3]12 The largest group of patients reported in the literature was of seven cases. 1 Only three of these reported cases were young and underlying optic neuritis was present in these three cases.…”

“…More than 90% of cases occur in people older than the age of 50 years and as many as 70% of patients have arterial hypertension, cardiovascular atherosclerotic disease, or diabetes mellitus. [1][2] Simultaneous occlusion of central retinal vein and artery is much rare in young adults, and information regarding risk factors in this group is scant. [1][2][3][4][5] Elevated plasma homocysteine is a recently recognized vascular risk factor for thrombosis and vascular diseases.…”

“…[1][2] Simultaneous occlusion of central retinal vein and artery is much rare in young adults, and information regarding risk factors in this group is scant. [1][2][3][4][5] Elevated plasma homocysteine is a recently recognized vascular risk factor for thrombosis and vascular diseases. [6][7] It is also shown to be a significant risk factor for retinal vascular occlusions.…”
