Toxic Keratopathy with Bi-layer Corneal Calcific Infiltrates Caused by Proparacaine Abuse—A Case Report

Abstract

This case describes a 27-year-old man who was seen in the emergency department for an epithelial defect and subsequently developed worsening visual acuity. His vision loss was attributed to proparacaine abuse that was unresponsive to medical management. After receiving penetrating keratoplasties in both eyes, histopathology demonstrated both superficial and deep calcific infiltrates, which have not previously been described in the setting of proparacaine toxicity.Copyright © Touch Medical Media 2020.
