Abstract
Purpose:
To describe unique findings on anterior segment optical coherence tomography (AS-OCT) in patients with Thygeson’s superficial punctate keratitis (SPK).
Methods:
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.
Results:
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.
Conclusions:
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.
