We read with great interest the article by Yeh et al1 that analyzed fundus autofluorescence (FAF) in white dot syndromes (WDS).
The patients were categorized into 3 groups on the basis of the presence of hypoautofluorescence in the fovea (central 1500 μm surrounding the foveola): normal FAF signal (no hypoautofluorescence), hypoautofluorescence affecting less than 50% (minimal), and hypoautofluorescence occupying 50% or more of the fovea (predominant).
