To assess the history, clinical course, and response to treatment of 14 patients with a bleb infection (blebitis) following glaucoma surgery.
A university referral center in Atlanta, Ga. Patients: Fourteen patients developed a bleb infection that ranged from 1 month to 22 years after glaucoma surgery. Infections were characterized by pain, a whitened bleb surrounded by intense conjunctival injection, marked anterior chamber reaction (hypopyon in six eyes), and a clear vitreous. Before infection, most blebs were described as thin. The results of Seidel's test were positive in six patients, and most patients had a low intraocular pressure without the use of any glaucoma medication.
Treatment consisted of hospitalization, intravenous antibiotic therapy, and hourly topical fortified cefazolin sodium and gentamicin sulfate.
The visual acuity in most patients improved to the level before the bleb infection, with only three eyes losing 2 or more lines of vision.
Bleb infection without vitreous involvement (blebitis) may be a precursor of endophthalmitis. With aggressive treatment, bleb infection appears to have a much better prognosis for visual recovery than endophthalmitis.
