RÉSUMÉ

We report a case of a 46-year-old female who developed infectious crystalline keratopathy (ICK) after Descemet's stripping endothelial keratoplasty (DSEK). She underwent DSEK for pseudophakic corneal edema in her left eye. Ten weeks after the procedure, the patient presented with complaints of blurred vision, redness in eye, and ocular pain. Slit lamp examination revealed white nonsuppurative branching deep stromal infiltrate. Microscopic examination of the Gram-stained smear showed gram-positive cocci. Streptococcus viridans was isolated on cultures. Isolated organism was sensitive to linezolid. Based on antibiotic sensitivity report, fortified linezolid (0.2%) eye drop was started on hourly basis. After 10 weeks of topical fortified linezolid (0.2%) therapy, complete resolution of infiltrate with significant corneal scarring and vascularization was seen. Infectious crystalline keratopathy can occur after DSEK.

RÉSUMÉ

The purpose of the study was to report a case of ulcerative keratitis caused by an unusual algae Prototheca wickerhamii in a diabetic patient. This study design was a case report. A 46-year-old male, who was a known diabetic for 3 years, had an injury to the left cornea with the sparks of fire from wielding at work that developed into an ulcerative keratitis over a period of next 3 months as the patient was not on any medication. Corneal scraping culture report and Vitek 2 system investigation result confirmed it to be a P. wickerhamii infection. The patient was started on intensive topical 1% voriconazole and 5% natamycin for 1 month and with no improvement subsequently underwent penetrating keratoplasty. No recurrence of infection postoperatively was noted. This opportunistic algae rarely known to cause human eye infections is so far reported in either patients with severe systemic immunosuppression causing posterior segment eye involvement or as postcorneal surgery infections. We report an ulcerative keratitis by P. wickerhamii in a diabetic patient post corneal trauma with no prior ocular surgery.
