Abstract
Clinical case

A 77-year-old patient had uneventful cataract surgery in the right eye under peribulbar anaesthesia. The next day, a severe and progressive eyelid swelling was noted, caused by an unknown allergic reaction to povidone–iodine. The allergic signs dissapeared by the fifth day, but amaurosis and a cherry-red spot were detected. Doppler ultrasound and CT angiography confirmed an 80% ipsilateral internal carotid artery stenosis.

Discussion

Retinal vascular occlusion after orbital loco-regional anaesthesia is rare. When this complication occurs, carotid disease, and local or systemic factors, should be evaluated.

Keywords:
Retinal artery occlusion
Phacoemulsification
Anaesthesia
Carotid stenosis
Hypersensitivity
Povidone–iodine
Resumen
Caso clínico

Paciente de 77 años, intervenido de catarata en ojo derecho bajo anestesia peribulbar, sin complicaciones. Al día siguiente presenta edema palpebral severo con empeoramiento progresivo, secundario a reacción alérgica no conocida a la povidona yodada. A los 5 días presenta una resolución del cuadro alérgico, detectándose amaurosis y mancha rojo cereza. El eco-Doppler de troncos supraaórticos y el angio-TAC confirman una estenosis del 80% de la arteria carótida interna ipsilateral.

Discusión

Las oclusiones vasculares retinianas constituyen una complicación infrecuente de la anestesia loco-regional orbitaria. Su aparición obliga a descartar causas subyacentes, como enfermedad carotídea, así como a reflexionar sobre los factores locales o sistémicos que han colaborado en su aparición.
