Endophthalmitis caused by Streptococcus pneumoniae
Abstract
PURPOSE: To investigate clinical settings, management strategies, antibiotic sensitivities, and visual acuity outcomes of endophthalmitis caused by Streptococcus pneumoniae.
DESIGN: Retrospective, observational case series.
METHODS: Records were reviewed of all patients with culture-positive endophthalmitis caused by Streptococcus pneumoniae treated at the Bascom Palmer Eye Institute between January 1, 1989 and December 31, 2003.
MAIN OUTCOME MEASURES: Visual acuity and antibiotic sensitivities.
RESULTS: Twenty-seven eyes of 27 patients met study inclusion criteria. The median follow-up was 7 months (range, 3 months to 10 years). Clinical settings included acute postoperative (10 eyes), corneal stitch abscess (5), corneal ulcer (3), bleb-associated (4), post-trauma (3), and endogenous (2). Eighteen cases (67%) were acute-onset (less than 3 weeks from event), with a median interval between event and presentation of endophthalmitis of 5 days (range, 1 day to 16 days). Nine cases (33%) were delayed-onset (median, 27 months; range, 3 to 121 months). Initial visual acuity was hand motions or better in 11 cases (41%). Initial therapeutic procedures included vitreous tap and injection of intravitreal antibiotics in 15 eyes (56%), pars plana vitrectomy and injection of intravitreal antibiotics in 10 eyes (37%), and evisceration in 2 eyes (7%). Seventeen (68%) of 25 eyes received intravitreal dexamethasone. Twelve patients (48%) received additional doses of intraocular antibiotics,…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 27 participants or records.
