Corneal perforation in undiagnosed Sjögren's syndrome following topical NSAID and steroid drops post routine cataract extraction

Abstract

A 74-year-old man presented with a progressive decrease in visual acuity and foreign body sensation in his right eye 8 days post uncomplicated phacoemulsification cataract surgery and intraocular lens insertion. The patient had been placed on a perioperative cataract regimen which consisted of G. Maxitrol (dexamethasone, polymyxin B sulfate, neomycin sulfate) four times a day and G. Yellox twice daily (bromfenac, a non-steroidal anti-inflammatory) for 2 weeks. On examination, he had a corneal ulcer and stromal thinning in his right eye which progressed to a full thickness perforation 12 hours later. The patient required a full thickness tectonic corneal transplant. Direct questioning revealed that this patient had both dry mouth and eyes. Serology revealed that the patient was positive for rheumatoid factor and for anti-Ro and anti-La antibodies. A parotid gland biopsy revealed significant lymphocytic infiltrate consistent with Sjögren's syndrome.
