Abstract

International audience; PURPOSE:To report the incidence of acute postoperative endophthalmitis (POE) after cataract surgery from 2005 to 2014 in France.DESIGN:Cohort study.PARTICIPANTS:Patients undergoing operation for cataract surgery by phacoemulsification and presenting acute POE.METHODS:We identified acute POE occurring within 6 weeks after phacoemulsification cataract surgery and the use of intracameral antibiotic injection during the surgical procedure by means of billing codes from a national database.MAIN OUTCOME MEASURES:Incidence of acute POE.RESULTS:From January 2005 to December 2014, 6 371 242 eyes in 3 983 525 patients underwent phacoemulsification cataract surgery. The incidence of acute POE after phacoemulsification decreased from 0.145% to 0.053% during this 10-year period; the unadjusted incidence rate ratio (IRR) (95% confidence interval) was 0.37 (0.32-0.42; P < 0.001). In multivariate analysis, intracameral antibiotic injection was associated with a lower risk of acute POE 0.53 (0.50-0.57; P < 0.001), whereas intraoperative posterior capsule rupture, combined surgery, and gender (male) were associated with a higher risk of acute POE: 5.24 (4.11-6.68), 1.77 (1.53-2.05), and 1.48 (1.40-1.56) (P < 0.001), respectively.CONCLUSIONS:Access to a national database allowed us to observe a decrease in acute POE after phacoemulsification cataract surgery from 2005 to 2014. Within the same period, the use of intracameral antibiotics during the surgical procedures increased.

Abstract

We present three unrelated post-cataract surgery endophthalmitis cases caused by Rhizobium radiobacter , hospitalized in three different hospitals. Early diagnosis was obtained in two cases by bacterial DNA detection in vitreous samples. All patients recovered from infection, but pars plana vitrectomy was needed in two patients due to rapid clinical deterioration.

Abstract

EA MERS CT3 Enjeu 3; International audience; PURPOSE: To correlate the initial ocular presentation with bacterial identification in 100 patients with acute postcataract endophthalmitis. METHODS: This was a prospective multicenter study. Demographic data, medical history, and the initial eye examination data were recorded on a standardized form. The relationship between bacterial identification and clinical factors at baseline was studied using univariate and multivariate analyses. RESULTS: One hundred patients were admitted to the hospital with a median delay of 6 days after cataract surgery. The main symptoms were loss of vision (94.9%) and pain (75.5%). Major clinical signs were hypopyon (72%), pupillary fibrin membrane (77.5%), and loss of fundus visibility (90%). Baseline factors significantly associated with microbiologic identification were as follows: diabetes mellitus, a shorter delay of onset, initial visual acuity limited to light perception, higher intraocular pressure, chemosis, pupillary fibrin membrane, loss of the red reflex, and reduced fundus visibility. As compared with other bacteria, the identification of Streptococcus species (n = 19) was more frequently associated with male gender, diabetes mellitus, initial visual acuity limited to light perception, and pain. The Staphylococcus aureus and Staphylococcus lugdunensis group (n = 14) differed from other coagulase-negative Staphylococcus groups (n = 33) in that those patients had greater hypopyon height. CONCLUSION: The baseline features of acute endophthalmitis after cataract surgery in the era of phacoemulsification are similar to those reported in the Endophthalmitis Vitrectomy Study 15 years ago and differ according to the bacterial species. The association between the clinical signs and the microbiologic identification suggests that initial characteristics other than visual acuity may be useful in identifying patients presumed to be infected with a virulent species.

Abstract

Purpose This study was designed to compare the diagnostic yield of microbiological analysis performed on diluted and undiluted vitreous samples from pars plana vitrectomy (PPV) in patients with acute postcataract endophthalmitis. Design Cohort study, evaluation of diagnostic test or technology. Participants Patients with acute postcataract endophthalmitis ( Methods Undiluted and diluted vitreous samples were taken from 34 consecutive patients at the beginning of PPV as part of the multicenter prospective study of the French Institutional Endophthalmitis Study (FRIENDS) group. Vitrectomy was performed after 1 (n = 12) or 2 (n = 22) intravitreous antibiotic injections. McNemar's nonparametric test was used to compare culture and polymerase chain reaction (PCR) results between diluted and undiluted samples. Main Outcome Measures Rate of positivity of conventional culture (brain heart infusion broth) and eubacterial PCR tests from undiluted and diluted vitreous samples. Results The microbiological analysis of both undiluted and diluted vitreous samples detected and identified a bacterial pathogen in 26 out of 34 cases (76.4%). The analysis of undiluted and diluted vitreous at the time of PPV, using eubacterial PCR and conventional culture, gave similar results ( P = 0.99; McNemar test). However, eubacterial PCR was more sensitive than culture in detecting bacteria in vitreous at the time of PPV (76% vs 6%; P = 0.001; McNemar test). The difference in sensitivity between the 2 techniques was primarily associated with false-negative culture results for undiluted samples (2/3 of cases), mainly for coagulase-negative staphylococci. Conclusions The microbiological results obtained combining PCR and culture techniques were similar for diluted vitreous and undiluted vitreous analysis. When eubacterial PCR is available, sampling diluted vitreous, an easier procedure, may replace sampling undiluted vitreous.

Abstract

International audience; PURPOSE: To report the clinical presentation and outcome of delayed-onset endophthalmitis caused by Moraxella species and to evaluate the eubacterial polymerase chain reaction (PCR) in aqueous humor samples for the microbiologic diagnosis. PATIENTS AND METHODS: Seven patients with bleb-related delayed onset-endophthalmitis caused by Moraxella were included in a prospective multicenter study (FRIENDS group, 2004 to 2005). Eubacterial PCR followed by direct sequencing and conventional cultures were carried out on aqueous humor samples taken before the first intravitreal antibiotic injection and on vitreous samples taken during pars plana vitrectomy. RESULTS: All cases were postoperative (5 after filtering surgery and 2 inadvertent filtering blebs). The mean delay of onset of endophthalmitis was 41.3 months+/-30.4 (SD) (range, 2.4 to 84.8) after surgery. Initial visual acuity was limited to light perception for 3 patients, hand motions for 2 patients, count fingers for 1 patient, and 20/125 for 1 patient. Functional recovery was variable with final visual acuity ranging from no light perception to 20/25. The eubacterial PCR carried out on aqueous humor provided microbiologic identification in all cases, whereas the cultures were negative in 6 of 7 cases. The eubacterial PCR performed on vitreous samples of 3 vitrectomized patients, after 2 intravitreal injections of antibiotics, identified Moraxella in 2 patients, whereas cultures were negative in all cases. CONCLUSIONS: Delayed-onset endophthalmitis caused by Moraxella occurs predominantly after a bleb-related infection. PCR is a more sensitive technique for the microbiologic diagnosis in this context than conventional culture.

Abstract

Acute postoperative endophthalmitis caused by Staphylococcus lugdunensis is infrequently reported in clinical studies. Five cases of acute postcataract surgery endophthalmitis caused by S. lugdunensis were taken from a multicenter prospective study conducted in four university-affiliated hospitals in France (2004 to 2005). These cases were characterized by severe ocular inflammation occurring with a mean delay of 7.6 days after cataract surgery, severe visual loss (hand motions or less in three cases), and dense infiltration of the vitreous. Each of these patients was initially treated by using a standard protocol with intravitreal (vancomycin and ceftazidime), systemic, and topical antibiotics. Given the severity of the endophthalmitis, even though bacteria were sensitive to intravitreal antibiotics, pars plana vitrectomy was needed in four cases. The final visual prognosis was complicated by severe retinal detachment in three cases. The microbiological diagnosis was reached by using conventional cultures with specific biochemical tests and eubacterial PCR amplification followed by direct sequencing.
