Clinical Case:
A 48-year-old woman with persistent superotemporal scotomas and photopsias for 2 months, and depigmented zones in the retina of both eyes with a trizonal pattern on multimodal imaging. Brain magnetic resonance imaging, positron emission tomography, antiretinal antibodies, immunological, infectious and tumor markers tests were negative, thus acute zonal occult outer retinopathy was diagnosed. Patient was treated with adalimumab. Nevertheless, 19 months later symptoms increased, and progression was detected on optic coherence tomography angiography, as well as in Humphrey visual field test and electroretinogram, thus, mycophenolate mofetil was added showing improvement and stabilization of the disease in a 4-year follow-up.
Discussion:
Optic coherence tomography angiography may be a potential tool to monitor progression and response to treatment in addition to other imaging modalities in acute zonal occult outer retinopathy, and the combination of adalimumab and mycophenolate may be useful in recurrent disease.
