Commonly occurring secondary to conditions such as dry eye disease, ocular surface toxicity, contact lens overwear, exposure, or viral infections, it primarily affects the anterior segment of the eye across diverse patient populations

Commonly occurring secondary to conditions such as dry eye disease, ocular surface toxicity, contact lens overwear, exposure, or viral infections, it primarily affects the anterior segment of the eye across diverse patient populations Clinically, affected patients typically present with ocular irritation, foreign body sensation, photophobia, excessive tearing, and intermittent visual blurring

Pathophysiologically, localized micro-epithelial breakdown compromises the corneal barrier, leading to characteristic fine, discrete lesions visible on slit-lamp biomicroscopy that readily take up diagnostic dyes such as sodium fluorescein

Clinically, affected patients typically present with ocular irritation, foreign body sensation, photophobia, excessive tearing, and intermittent visual blurring
