The corneal swab examined constructive for orthopoxvirus (Opox) by the real-time polymerase chain response (RT-PCR) assay. The affected person was subsequently prescribed 600 mg of tecovirimat (TPOXX) orally two occasions a day, along with topical ocular trifluridine.
One week of therapy with tecovirimat improved the affected person’s keratitis and ulceration. Nonetheless, his imaginative and prescient and photophobia didn’t enhance, even after finishing a 30-day course of those drugs.
