Corneal Endothelial Cell Toxicity Determines Long-Term Outcome After Ocular Exposure to Sulfur Mustard Vapor

Purpose: Ocular exposure to sulfur mustard (SM) vapor causes acute loss of corneal endothelial cells (CECs). Persistent corneal endothelial pathologies are observed in eyes that do not recover from SM exposure, suggesting that endothelial toxicity contributes to mustard gas keratopathy (MGK). Here, we evaluated the contributions of endothelial loss to acute and chronic corneal injuries in SM-exposed eyes. Methods: Rabbit eyes were exposed in...
