ABSTRACT
This report is on a 45-year-old male patient without underlying disease who presented with a Burkholderia pseudomallei-caused keratoscleritis in his right eye. Slit-lamp examination revealed multiple, indistinct corneal infiltrations with subconjunctival/scleral abscesses. Corneal tissue culture was positive for B. pseudomallei and confirmed by mass spectrometry. The patient was treated with fortified ceftazidime, fortified gentamicin eyedrops, and intravenous ceftazidime injection. Penetrating keratoplasty, including intracameral ceftazidime injections, was undertaken due to corneal lesion worsening. Scleral debridement with subconjunctival ceftazidime injections were undertaken due to the progression of the scleral abscess. After 2 months, the corneal and scleral lesions were inactive, and the systemic and topical antibiotics were tapered. This is the first case report of B. pseudomallei-caused keratoscleritis with photography. The patient was seen in an endemic geographical area with multiple corneal infiltrations and subconjunctival/scleral abscess. Systemic and topical antibiotics accompanied with surgery should be considered.

PURPOSE: To describe the findings of anterior segment optical coherence tomography (AS-OCT) in patients with microsporidial keratoconjunctivitis. METHODS: The observational study included 13 eyes from 13 patients. Slit-lamp photography and AS-OCT were performed using the Swept source OCT before corneal scraping. All cases were positive for Gram-chromotrope (modified trichrome) staining for Microsporidia spp. RESULTS: Three significant AS-OCT findings were observed. First, hyperreflective dots were limited to the epithelial layers of the cornea, and second, there were no extensions into the stromal layer in all cases. Last, hyperreflective dots slightly raised above the epithelial surface were observed in most cases (12/13%, 92.3%). CONCLUSIONS: AS-OCT represents an alternative, noninvasive tool to diagnose microsporidial keratoconjunctivitis, especially if corneal scraping is not possible.
