Abstract Purpose:Visual snow is characterized by persistent sensation of falling snow over the total visual area. In addition to migraine and tinnitus, anxiety or depression is an associated feature. Diagnosis is based on persistent photophobia, palinopia, entopsia, and impaired night vision for more than 3 months. We report a case of visual snow syndrome associated with psychological stress.

Case:A 25-year-old male visited us for advice. He remained jobless for 2 years after graduating a university. He had started seeing sandstorm since 3 months before. He felt persistent after-image and photophobia. He thought that his tinnitus had increased recently. No migraine was present.

Findings and Clinical Course:He was free of ophthalmological or neurological abnormalities. Wide-range assessment of vision-related essential skills(WAVES)showed normal eye-and-hand coordination, while he showed marked decline in visual perception. He was followed up for 12 months without medication. He has been doing well without difficulty in daily life.

Conclusion:Visual snow in the present case appears to have originated in visual cognitive function following stress in daily life.
