Ethical permission for this case report was obtained from the Nethradhama Eye Hospital institutional review board. A 40-year-old man, clerk by occupation, came with symptoms of pain, photophobia, watering, and blurring of vision in his right eye over a 2-month duration. He was in good general health and had no history of any systemic diseases, recent ocular trauma, ocular surgery, and contact lens use. He was diagnosed elsewhere with a nonhealing corneal ulcer and was on topical fluoroquinolone and antifungal fluconazole eyedrops. However, his condition showed no improvement. His earlier reports showed a positive Mantoux test with induration of 18 mm done 1 month previously, normal blood sugar levels, and seronegativity for HIV and hepatitis B and C virus. TB Gold test was negative. Upon presentation, best-corrected visual acuity was 0.48 logMAR in the right eye and 0.00 logMAR in the left eye. Slit lamp biomicroscopy in the right eye revealed a paracentral 3x3 mm horizontally oval corneal ulcer at the 5-7 o'clock meridian inferiorly 2 mm away from the limbus with underlying stromal edema (Figure 1). Corneal sensations over the ulcer were normal. Circumcorneal congestion was present. There were no satellite lesions. It was a whitish dry-looking ulcer. Anterior chamber showed mild reaction with 1+ cells and no hypopyon. The ulcer stained positively with fluorescein. The right pupil was reacting sluggishly to light in view of prior use of homatropine eyedrops that the patient had stopped using 1 week previously. Fundus showed mild vitreous haze with no focal retinal or choroidal pathology. Intraocular pressure was 18 mmHg on noncontact tonometry. The lacrimal sac bilaterally showed no regurgitation on pressure, and syringing showed patent lacrimal passage. B-scan ultrasonography was done. It was essentially normal with no evidence of scleritis. Systemic examination revealed no lymphadenopathy and clear respiratory system. Scraping was done with a number 15 blade and sent for microbiological examination. Gram staining revealed Gram-positive, irregular stain and forms of M. chelonae. ZN staining revealed acid-fast bacilli - red magenta rods typical of M. chelonae. Further culture on Lowenstein-Jensen media at 1 week revealed characteristic M. chelonae colonies - circular, smooth, and pale cream. The microorganism was identified based on its phenotypic characteristics, such as pigmentation of colonies growing in the darkness on Lowenstein-Jensen media - white, cream pigment production (nonchromogenic). Iron reuptake test was negative. Identification to species level was achieved on the basis of the growth characteristics, including growth in <7 days, growth at 37 C, failure of growth in the presence of 5% sodium chloride, pigment production, and positive catalase test. The patient was started on topical fortified amikacin (50 mg/mL) and tobramycin (14 mg/mL), and the symptoms resolved rapidly, with no presence of anterior chamber cells, and the ulcer healed in 3 weeks (Figure 2) with best-corrected visual acuity improving to 0.18 logMAR at 1 month posttreatment. The patient is on constant follow-up to look for any recurrence of infection. Written informed consent for the information to be used in this case report was obtained from the patient.
