Cilioretinal Artery Obstruction

Study on Clinical Profile of Patients With Retinal Vein Occlusion

“…According to literature, incidence of rubeosis is 20% among CRVO. 11,12 Among ischaemic eyes, rubeosis with or without NVG occur in 45 to 80% and this usually develops by 4-7 months of the occlusion. Neovascularisation of optic disc or retina is a rare complication but has been reported in 24% of ischaemic CRVO.…”

Hemiretinal arterial supply by the cilioretinal artery

“…This occurs as three clinical variants, Brown et al 3 (1) Isolated cilioretinal artery obstruction (40%). This has a good prognosis with 90% of eyes returning to 6/12 vision and 60% to 6/6.…”

Recentemente, tem sido descrita a associação combinada de oclusão da ACR e NOIA, relacionada com overdose de sildefanil citrato (31) (Viagra Pfizer Pharmaceuticals, New York, NY) e em casos de displasia fibromuscular da artéria renal com hipertensão arterial secundária (32) .…”
