Multimodal imaging of acute fovealitis with angular sign of Henle fiber layer hyperreflectivity (ASHH): Report of a case and review of the literature

Abstract

Acute retinal pigment epitheliitis (ARPE) is a rare and transient macular disorder that was first described by Krill and Deutman in 1972. Later, Gerardo Ledesma-Gil and Spaide described a novel disease named acute fovealitis in 2022. According to them, this entity was different from ARPE on the basis of distinct features found in high-resolution optical coherence tomography (OCT) imaging. Angular sign of Henle fiber layer hyperreflectivity (ASHH) is a newly described terminology that is caused by an acute insult to photoreceptor compartments. In this article, we report a case that has both the ophthalmoscopic and OCT features of acute fovealitis as described in the literature, with the presence of ASHH in the acute stage, which resolves on its own rapidly along with the symptoms without any intervention.
