Punctate epithelial erosions (PEE) secondary to exposure keratopathy

Contributor: Jesse Vislisel, MD

Photographer: Stefani Karakas, CRA

Punctate epithelial erosions (PEE) are evidence of ocular surface dryness. They represent areas of epithelial cell loss and therefore stain positively with fluorescein. The distribution of the PEE can provide information regarding the underlying etiology. Inferior PEE, as seen in this photograph, can be secondary to exposure, chronic blepharitis, or trichiasis. This patient previously underwent multiple eyelid surgeries resulting in exposure keratopathy.
