We read with great interest the comments made by Dr Gass concerning
our recent paper. Dr Gass is a recognized authority on acute outer retinal
dysfunction, and his thoughts on the etiology, clinical features, and classification
of these conditions are of utmost importance. His observations help to emphasize
some of the difficulty that has arisen regarding the classification of these
patients. He expresses concerns about the inclusion criteria of our study
and our conclusions that the entity of acute idiopathic blind spot enlargement
(AIBSE) is different from the other forms of acute outer retinal dysfunction.
