Late progression of visual loss from ocular quinine toxicity

Abstract

C2), making this possibility unlikely. Another cause for flow voids is the low velocity of flow such that it falls under the OCTA decorrelation threshold for detection (less than 0.3 mm/s in this case). This is also unlikely given the clinical setting and significant improvement of signal after treatment using the same machine. One may test this possibility using a custom variable interscan time analysis hardwareÀsoftware framework to detect slower flow.This case signifies the value of multimodal imaging and particularly OCTA not only to diagnose a life-threatening condition but also to utilize this imaging technique to determine the extent of choroidal infiltration at a microscopic level and to monitor the course of ocular disease with restoration of choroidal vascular flow indicating a response to treatment.
