Thygeson’s superficial punctate keratitis

Thygeson's superficial punctate keratitis (TSPK) is a chronic, bilateral epithelial keratitis. Dr Philips Thygeson first reported TSPK in 1950. Although the etiology of TSPK remains unknown, it has been reported to be associated with viral and autoimmune pathologies. The disease course is characterized by exacerbations and remissions. The classical finding on slit lamp examination is the presence of distinctive coarse, raised, oval-shaped corneal epithelium lesions. Patients commonly present with ocular irritation and rarely with reduced visual acuity. Topical corticosteroids are the mainstay of treatment. Other less commonly used treatments included topical cyclosporine, contact lenses and corneal laser.
