- Clinical features:
- Symptoms include ocular discomfort, foreign body sensation,
tearing, photophobia and conjunctival hyperemia.
- Signs:
- Single or multiple, 1-2 mm corneal infiltrates with minimal
overlying epithelium disruption
- Infiltrates are usually located superiorly and parallel
to the limbus with an area of clear cornea between the infiltrate
and the limbus.
- May occur secondary to:
- Contact lens wear as a consequence of corneal hypoxia
- Immune response (hypersensitivity) to preservatives
in contact lens care products
- Management:
- Treatment options include cessation of contact lens wear, topical
antibiotics and/or topical corticosteroids.
- Corneal scrapings for stains and cultures should be considered
with larger infiltrates complicated with epithelial defect, anterior
chamber inflammation and ocular pain.
