To describe unique findings on anterior segment optical coherence tomography (AS-OCT) in patients with Thygeson’s superficial punctate keratitis (SPK).
The charts of all patients diagnosed with Thygeson’s SPK at the UC Davis Eye Center were analyzed. Patients who had AS-OCT and slit lamp photos performed were identified and images were obtained and analyzed.
Three patients were identified. All patients had classic signs and symptoms consistent with Thygeson’s SPK as determined by a fellowship-trained Cornea specialist. Images from the patient’s slit lamp photos were carefully aligned with the AS-OCT images from each patient. All three patients demonstrated hyperreflective epithelial and subepithelial deposits on AS-OCT which corresponded to the areas of SPK seen on imaging. These deposits could also be clearly seen as elevated above the rest of the corneal surface on AS-OCT.
There appear to be characteristic findings on anterior segment optical coherence tomography (AS-OCT) of Thygeson’s SPK. AS-OCT can therefore be an useful aid in diagnosing these patients.
