Purpose: To discuss the features of an artifact on optical coherence tomography angiography (OCTA), termed "pupil vignetting artifact," and describe how it may masquerade as true chorioretinal pathology.
Design: This was a retrospective, observational case series.
Methods: The authors studied 12 eyes at a vitreoretinal clinic in Eastern India, reviewing a dark shadow such as an artifact on OCTA images.
Purpose: Angular sign of Henle fiber layer hyperreflectivity is a marker of Henle fibre layer ischemia. Our aim is to describe angular sign of Henle fiber layer hyperreflectivity as a novel optical coherence tomography sign in Purtscher and Purtscher-like retinopathy.
Methods: Here, we present three cases, one classical Purtscher retinopathy and two Purtscher-like retinopathy who had angular sign of Henle fiber layer hyperreflectivity on spectral domain optical coherence tomography imaging.
Background: The present study compared clinical features and outcomes of central serous chorioretinopathy (CSC) with and without pachychoroid.
Methods: It was a retrospective, longitudinal, record-based study which included eyes with CSC. Patients underwent spectral domain optical coherence tomography and differentiated between pachychoroid and non-pachychoroid groups.
