Carotid Cavernous Fistula with Central Retinal Vein Occlusion

Purpose: To report a rare case of slow progression carotid cavernous fistula (CCF) with central retinal vein occlusion (CRVO).Case summary: A 66-year-old man presented conjunctival injection and proptosis in the right eye. Best-corrected visual acuity was 0.8 0.5 left eye, respectively, vessel enlargement subconjunctival hemorrhage were observed eye on slit lamp examination. Due to suspicion CCF, computed tomography, tomography angiography, magnetic resonance imaging, angiography performed. These analyses showed no vascular abnormalities associated arteriovenous shunt, so patient followed up closely. About 1 month later, his engorgement became severe CRVO derived from venous stasis by CCF occurred, transfemoral cerebral performed diagnosis made. Intravitreal anti-vascular endothelial growth factor for CRVO, best corrected improved 1.0 eye.Conclusions: Slowly progressing can be accompanied intraocular disease, such as appropriate through detailed evaluation is important treatment.
