Abstract
Three patients developed cellulitis and skin necrosis following fluorescein dye estravasation. This experience prompted a survey of the Macula Society membership to determine whether this complication of fluorescein angiography is as rare as the paucity of cases in the literature suggests. In addition, the manufacturer was asked to reexamine the dye lot to determine whether an impurity had been introduced unintentionally during the manufacturing process. No impurity was found in the dye lots tested. The survey disclosed only nine additional cases of skin necrosis, leading to the conclusion that skin necrosis probably represents a rare, idiosyncratic reaction. Although fluorescein angiography remains a safe procedure, efforts should be directed toward prevention of dye extravasation. When extravasation does occur, prompt and proper medical attention with close follow-up study may minimize the likelihood of skin necrosis.
