A 65 years old man presented with complaints of pain, redness, and diminution of vision in the left eye for the past 1 month following trauma with vegetative matter. The best-corrected visual acuity (BCVA) of the left eye was counting fingers close to the face. Slit-lamp examination revealed a 7*6 mm corneal abscess with central perforation with iris incarceration and pseudocornea formation, surrounded by stromal infiltrates [Figure 1]a.

On investigation, the patient had no systemic illness and was seronegative. A clinical diagnosis of perforated fungal keratitis was made. Therapeutic keratoplasty was performed using a Cornisol—preserved donor cornea.
After surgery, the patient received a combination of topical (5% natamycin, 1% voriconazole 1 hourly) and oral antifungal (Tab Ketoconazole 200 mg BD) therapy for 6 weeks.
Host corneal button culture on Sabouraud's dextrose agar (SDA) revealed white-colored growth which later turned wooly yellowish-green, progressing to dark green color with rapidly diffusing dark red pigment. Slide mounted with Lactophenol cotton blue demonstrated brush-like conidial heads [Figure 2].

The sample was also cultured on Brain Heart Infusion Agar (BHIA) showing the mold-to-yeast conversion, which is diagnostic of P. marneffei.
At 1-year follow-up [Figure 1]b, the cornea was clear and BCVA was 20/80.
| Discussion|| |
P. marneffei keratitis is an opportunistic infection, associated with immunocompromised states, especially with acquired immunodeficiency syndrome (AIDS).
There are very few cases of Penicillium keratitis reported in the literature [Table 1]. No information is available on differences in P. marneffei induced keratitis in an immunocompetent or immunocompromised host. Vyawahare et al. reported P. marneffei keratitis, with punched-out margins and no satellite lesions, in an immunocompetent farmer. He was treated with amphotericin B 0.15% and natamycin 5% topically. In a case reported by Arora et al. of a 12-year-old patient, diagnosed as shield ulcer, Penicillium was isolated from the infiltrate, which was deep stromal.
Our patient presented with a corneal abscess and perforation. He underwent therapeutic penetrating keratoplasty and is doing well. Although P. marneffei keratitis is rare in immunocompetent individuals, we emphasize the need for complete microbiological evaluation for proper diagnosis and appropriate treatment.
