To the Editor.—
In their recent reply to Dr Stewart's1 letter to the editor (October 1987), Dr Wehr and colleagues2 erred in their citation of their own second reference by the omission of my name as an author.3 As clearly stated in the "Methods" section of that initial report on seasonal affective disorder and light therapy, I made the initial observations on the seasonal disorder and the initial treatments with light. Since that time, I have gone on to treat over 200 patients with the seasonal disorder. As a result of my experience,4 I support Dr Stewart's comments in part: (1) Light therapy is not particularly effective for the majority of my patients with the seasonal disorder. Only approximately 15% of these patients respond to light, and these patients are those who are only mildly ill and have had few or no hospitalizations for their disorder.
