A 41-year-old woman who is a carrier of human T-lymphotropic virus 1 (HTLV-1) experienced a decrease in the vision of her left eye in 2002. A large, deep, pale, slightly thickened lesion with brown pigment (Figure 1A) and lobular leakage hyperfluorescence and punctate hypofluorescence (Figure 1B and C) developed in June 2002. Some lesions fused 1 week later (Figure 1D-F). Six weeks after symptom onset, visual acuity in the left eye improved to 20/20. The lesions showed pigment proliferation (Figure 1G) and leakage resolved (Figure 1H); however, peculiar hypofluorescence developed (Figure 1I). Six months after symptom onset, brown pigment proliferation, subretinal fibrosis, and peripheral pigmentary streaks developed (Figure 2). Visual acuity remained 20/20 OS at the last follow-up visit in 2006.
