Contact Lens Peripheral Ulcer

Also known as: CLPU, contact lens peripheral ulcer, CL peripheral ulcer, contact lens infiltrate, peripheral corneal infiltrate contact lens, sterile corneal infiltrate CL, CL ulcer, contact lens keratitis peripheral

Overview

A sterile inflammatory corneal infiltrate at the peripheral or paracentral cornea associated with contact lens wear. Caused by an immune response to bacterial toxins (typically Staphylococci or Gram-negative organisms) or inflammatory mediators, rather than true infection. Distinct from microbial keratitis: CLPU infiltrates are typically small (< 1mm), peripheral, with minimal or no staining, and occur with lens wear — not a true corneal infection.
