ABSTRACT: Haemophilus aphrophilus is a rare cause of ocular infection. It has been reported once as a cause of late-onset endophthalmitis in a patient with an inadvertent bleb after cataract surgery. We present a case of Haemophilus aphrophilus bleb infection after a mitomycin trabeculectomy.
A 56-year-old woman presented with a bleb infection 10 weeks after a mitomycin C augmented trabeculectomy at a University tertiary referral practice of one of the authors (GET). The causative organism was Haemophilus aphrophilus, identified by the Toronto Public Health Laboratory, Ontario, Canada.
The bleb infection resolved following topical, subconjunctival and intravenous antibiotic therapy. A formal bleb revision was required to repair a persistent bleb leak.
Patients who have had trabeculectomies augmented with mitomycin C may be predisposed to bleb infection with unusual organisms. Prompt diagnosis and treatment is necessary to control the infection. Increased awareness and communication with laboratory personnel may increase the isolation of this fastidious organism.

ABSTRACT: A case of infectious crystalline keratopathy in a patient who had undergone trabeculectomy without 5-fluorouracil is described. Chronic low-dose topical steroids were employed. Crystalline keratopathy occurring in this setting has not been previously described. A 73-year-old diabetic women presented with feathery crystal-like corneal infiltrates. These were cultured and treated with antibiotics based on the sensitivities. The cultures showed a nutritional variant of Streptococcus that was difficult to grow on routine culture plates. It was sensitive to vancomycin. Resolution of the infection occurred with topical treatment. Infectious crystalline keratopathy is a rare but classical corneal infection. The microbiological characteristics that give rise to its clinical appearance and laboratory characteristics are discussed. A rationale for diagnosis and treatment is suggested.
