Punctate keratitis is an ocular condition characterized by multifocal, pinpoint inflammation or cell death across the corneal epithelium It affects the ocular surface and commonly arises in patients experiencing dry eye syndrome, contact lens overwear, ocular surface toxicity, ultraviolet exposure, or infectious and inflammatory etiologies

Punctate keratitis is an ocular condition characterized by multifocal, pinpoint inflammation or cell death across the corneal epithelium Pathophysiologically, disruption of the tear film and mechanical or microbial insult cause focal loss of epithelial integrity and cellular infiltration Clinically, it presents with eye irritation, foreign body sensation, photophobia, and scattered, punctate intraepithelial lesions readily identified by diagnostic fluorescein staining
