ABSTRACT

Purpose: To describe a case of microsporidial stromal keratitis with endophthalmitis in an immunocompetent patient.Methods: Case reportResults: A 58-year-old HIV-negative man presented with stromal keratitis in his right eye. The patient demonstrated subsequent vitritis, multifocal retinitis and arteritis, and macular edema with recurrent vitreous hemorrhage after therapeutic keratoplasty. Numerous microsporidial spores were detected in corneal tissues by modified trichrome stain. Both corneal tissues and vitreous sample of the affected eye showed positive results by polymerase chain reaction targeting the microsporidial small subunit rRNA gene whose sequences belonged to Vittaforma corneae. Post-keratoplasty and vitrectomy, his best-corrected visual acuity was hand motion due to pale optic disc.Conclusion: Endophthalmitis can be a consequence of microsporidial stromal keratitis in an immunocompetent host. Early recognition and prompt treatment should be considered in patients diagnosed with microsporidial keratitis presenting with mild vitritis, retinitis, and recurrent vitreous hemorrhage.
