A Case of Acute Zonal Occult Outer Retinopathy in which Oct en Face Imaging Was Useful for Diagnosis and Follow-up

Acta Med Okayama. 2023 Aug;77(4):433-437. doi: 10.18926/AMO/65756.

Abstract

A 23-year-old woman presented with a 1-month history of visual abnormalities in her right eye. A visual field test revealed temporal abnormalities in the right eye. Optical coherence tomography revealed an indistinct ellipsoid zone (EZ) on the B-scan image and hyporeflective areas in the EZ layer on the en face image in the right eye. We diagnosed the patient with acute zonal occult outer retinopathy. Visual field tests and B-scan images improved to almost normal at 6 months, but hyporeflective areas remained on the en face images. Thus, en face images may be more sensitive at detecting abnormalities in the outer retina than other modalities.

Keywords: acute zonal occult outer retinopathy; ellipsoid zone; en face image; optical coherence tomography.
