Herpes simplex virus bullous keratitis misdiagnosed as a case of pseudophakic bullous keratopathy with secondary glaucoma: an unusual presentation

Abstract

Abstract Purpose To report an unusual case of herpetic bullous keratitis misdiagnosed as a case of pseudophakic bullous keratopathy with secondary glaucoma. Results A retrospective analysis of the case record of a 60-year-old man who had earlier undergone bilateral cataract surgery, was done. He presented with a complaint of decrease in vision in the right eye of 20 days duration. On examination, cornea showed epithelial bullae all over the surface with stromal and epithelial edema. Intraocular pressure was 30 mm of Hg in RE. He was treated with anti-glaucoma medications. Two dendritic lesions were seen in the cornea during a subsequent visit four days later. Virological investigations confirmed a diagnosis of Herpes simplex keratitis. He was treated with topical acyclovir. Conclusions This case highlights the fact that herpes simplex keratitis can present initially as a more diffuse corneal stromal and epithelial edema with epithelial bullae mimicking bullous keratopathy. Herpetic bullous keratitis, although unusual, should be considered in the differential diagnosis under such circumstances.
