Isolated corneal involvement by Lichen Planus - multi-modal evaluation

Abstract

Purpose To describe a case of ocular Lichen Planus, successfully managed using a multimodal evaulation, including Anterior Segment OCT (AS-OCT). Observations A female patient in her forties with a history of cutaneous Lichen Planus presents with blurred vision and burning eye sensation. Anterior segment evaluation revealed bilateral punctate keratitis, stromal haze and subepithelial pigmented dots. AS-OCT was pivotal for diagnosis, showing anterior stromal hyperreflective dots. A diagnosis of ocular Lichen Planus was estabilished and the patient was treated with topical hydrocortisone, with complete subsidence of the complaints. Conclusions and Importance Ocular Lichen Planus can present as isolated corneal involvement independent from severe cicatrizing conjunctivitis. Appropriate and timely treatment can prevent irreversible ocular surface disease. Ophthalmologists should be aware of Lichenoid Tissue Reaction (LTR) disorders, especially in patients with relentless blepharitis and/or ocular surface disease.
