Angular Sign of Henle Fiber Layer Hyperreflectivity in Purtscher and Purtscher like Retinopathy.

Angular Sign of Henle Fiber Layer Hyperreflectivity (ASHH) is a marker of Henle Fibre layer ischemia. Our aim is to describe ASHH as a novel OCT sign in Purtscher and Purtscher like retinopathy. Here we present 3 Cases, one classical Purtscher Retinopathy and 2 Purtscher like Retinopathy who had ASHH on SD OCT imaging. Modalities like Colour fundus photography, cross-sectional OCT, OCT angiography (OCTA) and fluorescein angiography were used. Presence ASHH in Purtscher Retinopathy and Purtscher like retinopathy points towards a deep capillary plexus insult and has prognostic implications.
