Isolated retinal cotton wool spot after coronary angiography

ABSTRACT

Visual symptoms after coronary angiography are rarely encountered and mostly related to contrast induced transient cortical blindness or retinal artery occlusions. We report an intriguing case of a 50-year-old woman, who presented with vision deterioration in her right eye 12 h after coronary angiography for cardiac palpitation.
