Anterior segment optical coherence tomography in hyperreflective cysts of fungal keratitis

DOI: 10.37039/1982.8551.20250079

Anterior segment-optical coherence tomography (AS-OCT) imaging provide a range of characteristic patterns that could be used as an additional tool in the diagnosis and management of infectious keratitis.^(,) We describe the AS-OCT findings of a patient with fungal keratitis.

A 65-year-old man with a history of vegetal trauma to his left eye, presented to the emergency room complaining of pain and blurred vision in the right for three weeks. The best corrected visual acuity was 3/10 in the left eye. Biomicroscopic examination showed a conjunctival hyperemia, a large paracentral inferior corneal ulcer, underlaid with stromal infiltrate. A corneal microabscess was detected at 2 o’clock without fluorescein staining. Anterior segment-optical coherence tomography showed the inferior epithelial defect underlaid with a hyper-reflective stromal infiltrate and posterior masking (). The microabcess at 2 o’clock was like a small stromal hyper-reflective cystic space with intact epithelium (). Even though the reflectivity was high, the mask effect was absent.
