RESUMO
CASE REPORT: We present the case of a patient who underwent photodynamic therapy (PDT) for adult-onset foveomacular vitelliform dystrophy (AFVD) at another clinic, having been misdiagnosed as having a choroidal neovascular membrane. Two years post-treatment, the patient had severe central visual loss and showed angiographic signs of choroidal hypoperfusion. DISCUSSION: AFVD is a rare clinical entity, usually having a fair visual prognosis, although some cases may show episodes of severe visual loss during their clinical course. Optical coherence tomography (OCT) is valuable in revealing the distinct images of AFVD from the features of a choroidal neovascular membrane. PDT using verteporfin may have negative long term effects if used in patients with AFVD.
