Keratitis

Keratitis is inflammation of the cornea, infective (bacterial/viral/fungal) or noninfectious (autoimmune/exposure/neurotrophic). Clinical: pain, photophobia, lacrimation, redness, and blurred vision, with corneal infiltrate/epithelial defect on slit lamp. It may progress to ulceration/perforation. Treatment: urgent ophthalmology; identify etiology (culture/stain/PCR); targeted topical antibiotics/antivirals/antifungals; cycloplegics; manage underlying cause; corneal transplant if scarring/perforation.
