  • Abstract
  • Look Inside

We examined 45 patients who were receiving systemic interferon for 8 to 24 weeks. Retinal vascular lesions were detected in 18 cases. All the 18 cases showed cottonwool spots and 10 cases showed, additionally, retinal hemorrhages. The visual acuity was 0.7 or better in all the cases. These fundus lesions tended to develop after 2 weeks to 5 months after initiation of interferon therapy. They disappeared spontaneously after discontinuation of the therapy.
