Superficial punctate keratitis (SPK), also described as punctate epithelial keratitis (PEK) is a sign of mild neurotrophic keratitis (NK) If left undiagnosed, NK can progress from mild to moderate to severe and may ultimately lead to profound vision loss. "Within approximately 24 hours, these vesicles coalesce to form the classic dendrite that most ophthalmologists recognize." They represent areas of epithelial cell loss and therefore stain positively with fluorescein. Retrospective study of in vivo confocal microscopy (IVCM) in 160 eyes from 160 patients with T2DM diagnosed with CPE due to a single cause. Prior to a clinical examination, serologies may be useful in understanding whether the patient is in the active or inflammatory phase of disease. Slit lamp exam typically shows conjunctival injection, chemosis, and punctate staining of the corneal epithelium with fluorescein dye. Also, does punctate keratitis go away? Patients with oculopharyngeal dystrophy did not develop PEE.
