Choroidal Nevus in an Eye with Polypoidal Choroidal Vasculopathy

PURPOSE To report an eye with polypoidal choroidal vasculopathy (PCV) and a choroidal nevus. METHODS This is an observational case report. RESULTS A healthy 69-year-old woman was referred to the Osaka University Hospital with a diagnosis of a macular tumor. She complained of having distorted vision in her left eye. The medical history of the patient was unremarkable. At the initial examination, her best-corrected visual acuity (BCVA) was 20/20 in both eyes, and the intraocular pressure was 18 mm Hg in both eyes. A slit-lamp examination showed no abnormalities in the anterior segment of both eyes and a fundus examination of the left eye showed a slightly elevated juxtafoveal chorioretinal lesion and polyp-like reddish-orange lesions. The juxtafoveal choroidal lesion was located beneath a choroidal neovascularization (CNV). An optical coherence tomography confirmed CNV with pigment epithelial detachment (PED). Fluorescein angiography showed juxtafoveal hyperfluorescence due to CNV. Indocyanine green angiography demonstrated a branching choroidal vascular network that resembled polypoidal lesions. A fundus autofluorescence showed a mosaic pattern and a slight hyperautofluorescence at the CNV. We diagnosed the patient as having PCV. Aflibercept was injected intravitreally because of her PED. After the injection, PED improved and her visual acuity remained stable during the 12-month follow-up period. CONCLUSIONS In cases of PCV, FAF images are helpful in determining the status of the posterior pole. Intravitreal injections of aflibercept can improve PED associated with CNV, and the BCVA will remain stable for at least 12 months.
