Abstract

Purpose: To report the long-term prognosis of a case of infant frosted branch angiitis.<br>Case: A six-year-old boy presented with blurred vision following fever due to streptococcal infection. His best corrected visual acuity（BCVA）was 0.15/0.1（right/left）, and critical flicker frequency was 19 Hz/18 Hz（right/left）, while kinetic Goldmann perimetry revealed central defects. No abnormalities were found in the anterior segment and the ocular media without iridocyclitis. These findings led to the diagnosis of frosted branch angiitis. Although optic neuritis was suspected based on physical examination, no significant findings were noted on magnetic resonance imaging.<br>　The patient was treated with oral corticosteroids. His BCVA improved to 1.2 in both eyes, with a critical flicker frequency of 29 Hz/30 Hz（right/left）, while the central defects disappeared. Although axial myopia was noted 11 years after the onset, there was no recurrence of frosted branch angiitis.<br>Conclusion: Frosted branch angiitis did not recur during a period of 11 years.
