Differential Diagnoses
Conjunctivitis
Corneal Ulceration and Ulcerative
Keratitis
Iritis and Uveitis
Other Problems to Be Considered
Dry eye syndrome - Poor tear lake or a decreased tear break-up time
Blepharitis - Erythema, telangiectasias, and crusting of the eyelid margins
Trauma - Can occur from relatively mild trauma, such as chronic eye rubbing
Exposure keratopathy - Poor eyelid closure with failure to cover the entire globe
Topical drug toxicity - Neomycin, tobramycin, or drops with preservatives, including artificial tears
Contact lens–related disorder - Chemical toxicity, tight-lens syndrome, contact lens overwearing syndrome, or giant papillary conjunctivitis
Thygeson SPK - Bilateral, recurrent SPK without conjunctival injection
Foreign body under the upper eyelid - Typically linear SPK with fine scratches arranged vertically
Trichiasis and/or distichiasis - Eyelashes rubbing on the cornea
Entropion or ectropion - superior or inferior SPK
Floppy lid syndrome - Extremely loose lids that pull away from the eye very easily
Associated retinopathy - Sun-gazer retinopathy associated with UV keratitis, seen particularly in psychiatric patients who stare directly into the sun
Workup
Procedures
- Perform standard slit lamp examination with fluorescein.
