A 31-year-old Australian resident presented with a 2-week history of painless visual loss in her right eye. Her only overseas travel had been a holiday in Thailand 4 years earlier. Her visual acuity was 20/200 OD and fundoscopy revealed a curvilinear chorioretinal scar that extended from the temporal ora serrata to the right macula where it terminated in a gray, edematous subfoveal lesion (Figure 1). There was no anterior uveitis or vitritis. Fluorescein angiography revealed a classic subfoveal choroidal neovascular membrane (CNVM) (Figure 2). The patient consented to a single treatment of photodynamic therapy with verteporfin in combination with a 4-mg intravitreal injection of triamcinolone acetonide. Three months later, her visual acuity improved to 20/30 with no evidence of extension in the chorioretinal scar. Repeat fluorescein angiography and optical coherence tomography confirmed complete cessation of leakage from the CNVM and resolution of the intraretinal edema and subretinal fluid (Figure 2).
