Superficial Punctate Keratitis

Superficial punctate keratitis (SPK) is multiple punctate epithelial defects on the corneal surface, staining with fluorescein, due to dry eye, viral keratitis (adenovirus/HSV), exposure, or medication toxicity. Clinical: grittiness, photophobia, and punctate stains on slit lamp. Treatment: identify and treat the cause (dry-eye lubricants, antiviral, exposure protection); remove toxic drops; lubricate the ocular surface.

Common Symptoms

Grittiness/photophobia; punctate fluorescein-stained epithelial defects; by cause (dry eye/viral/exposure)

Causes and Pathogenesis

Dry eye/viral/exposure/toxic drops cause punctate epithelial corneal damage.

Treatment

Treat cause; lubricants; antiviral if viral; protect ocular surface; stop toxic drops

Preventive Measures

Treat dry eye; protect ocular surface.
