Purpose: To describe an extrafoveal presentation of focal choroidal excavation and corresponding imaging findings. Methods: Retrospective case report. Patients: Single patient with diagnosis of extrafoveal focal choroidal excavation. Results: A 28-year-old man was referred for evaluation of a suspicious lesion in his right posterior fundus. Functional examination demonstrated best-corrected visual acuity of 20/40 in the right eye and 20/20 in the left eye. Ophthalmoscopy exam and fundus photography revealed a yellowish lesion superior to the fovea of the right eye. The lesion was hyperfluorescent on fundus autofluorescence imaging and late phase fluorescein angiography demonstrated staining of the lesion without leakage. Optical coherence tomography (OCT) of the lesion was consistent with focal choroidal excavation. Five months after presentation, the patient's vision, exam, and imaging remained stable. Discussion: Focal choroidal excavation is a recently recognized clinical entity that is often incidentally found, and presents asymptomatic or with mildly decreased visual acuity in the affected eye. It has characteristic findings on optical coherence tomography (OCT) that can be used to distinguish it from other retinal lesions that may appear similar on ophthalmoscopy. We present the case of an uncommon extrafoveal presentation of FCE at a relatively young age, which may represent either a congenital abnormality or the sequelae of an unidentified chronic process. While most FCE remain stable, patients are often followed for lesion progression and the possibility of choroidal vascular pathology which might necessitate intervention.
