Mihalache A, Patil NS, Popovic MM, Sedrak P, Kertes PJ, Muni RH. Tap and inject of intravitreal antibiotics versus pars plana vitrectomy for post-cataract surgery endophthalmitis: a meta-analysis. CANADIAN JOURNAL OF OPHTHALMOLOGY 2024; 59:73-78. [PMID: 36803934 DOI: 10.1016/j.jcjo.2023.01.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 11/28/2022] [Accepted: 01/24/2023] [Indexed: 02/18/2023]
Abstract
BACKGROUND The efficacy and safety of initial tap and inject (T/I) compared with pars plana vitrectomy (PPV) for acute postoperative bacterial endophthalmitis following cataract surgery is unclear. Understanding the comparative safety and efficacy of initial T/I and initial PPV can provide context for treatment decision making in this setting. METHODS A systematic literature search was performed on Ovid MEDLINE, EMBASE, and the Cochrane Library from January 1990 to January 2021. Comparative studies reporting on final best-corrected visual acuity (BCVA) following initial T/I or PPV in patients with infectious endophthalmitis secondary to cataract surgery were included. Cochrane's Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I) was used to evaluate the risk of bias, and GRADE criteria were used to assess certainty of evidence. A random-effects model was used for meta-analysis. RESULTS Seven nonrandomized studies reporting on 188 eyes at baseline were included in this meta-analysis. Initial T/I achieved a significantly better BCVA at last study observation than initial PPV (weighted mean difference [WMD] = -0.61 logMAR; 95% CI, -1.19 to -0.03; p = 0.04; I2 = 89%; n = 7 studies; GRADE = very low). The incidence of enucleation was similar between initial T/I and initial PPV (risk ratio [RR] = 0.73; 95% CI, 0.09-6.25; p = 0.78; I2 = 4%; n = 2 studies; GRADE = very low). The risk of retinal detachment was similar between treatment modalities (RR = 0.29; 95% CI, 0.01-5.94; p = 0.42; I2 = 52%; n = 2 studies; GRADE = very low). CONCLUSIONS The quality of evidence in this setting is limited. T/I had a significantly better BCVA at last study observation than initial PPV. Safety profiles were similar between T/I and PPV.

Literature- and Experience-Based Consensus for Acute Post-operative Endophthalmitis and Endogenous Endophthalmitis in Taiwan. Ophthalmol Ther 2024; 13:1-19. [PMID: 37934385 PMCID: PMC10776529 DOI: 10.1007/s40123-023-00835-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Accepted: 10/06/2023] [Indexed: 11/08/2023] Open
Abstract
Clinical practices on acute post-operative and endogenous endophthalmitis (EnE) are highly variable among clinicians due to a lack of up-to-date, high-quality evidential support. An expert consensus is thus much needed. A panel consisting of ten retinal specialists in Taiwan was organized. They evaluated relevant literature and developed key questions regarding acute post-operative and EnE that are cardinal for practice but yet to have conclusive evidence. The panel then attempted to reach consensus on all the key questions accordingly. There were eight key questions proposed and their respective consensus statements were summarized as follows: Gram staining and culture are still the standard procedures for the diagnosis of endophthalmitis. Vitrectomy is recommended to be performed earlier than the timing proposed by the Endophthalmitis Vitrectomy Study (EVS). Routine intracameral antibiotic injection for post-cataract surgery endophthalmitis prophylaxis is not recommended because of potential compounding error hazards and a lack of support from high-quality studies. Routine fundus examination is recommended for all patients with pyogenic liver abscess. In EnE, vitrectomy is recommended if diffused and dense vitritis is present, or if the disease progresses. These consensus statements may work as handy guidance or reference for clinical practices of acute post-operative and EnE.

Abstract
Objective: To compare the incidence of postoperative endophthalmitis after eventful cataract surgery i.e. posterior capsular rupture, in patients managed with anterior vitrectomy and intra ocular lens implantation intraoperatively to patients managed with anterior vitrectomy and intraocular lens implantation two weeks after the posterior capsule rupture. Methods: This comparative study was conducted at Layton Rahamatullah Benevolent Trust, Free Base Eye Hospital Korangi, Karachi from February 2017 to December 2018. The study included two groups, group A had patients with intra ocular lens implanted after posterior capsule rupture intraoperatively, while Group B had patients with intra ocular lens implanted after two weeks of initial surgery. Incidence rate of post-operative endophthalmitis was compared between two groups, which happened within six weeks after intra ocular lens implantation surgery. Results: Total number of cataract surgeries that were performed during the study was 37,969. Incidence of postoperative endophthalmitis was 0.0019%. The study enrolled patients with complicated cataract surgeries that were 3508 (0.09%). Out of which incidence of post-operative endophthalmitis that occurred in group A was 0.007% and group B was 0.002%. (p value <0.05). The study also found that complicated extracapsular cataract extraction with intraocular lens implantation had more cases of endophthalmitis compared to phacoemulsification with intraocular lens. Conclusion: This study showed that management of posterior capsular rupture through anterior vitrectomy and secondary intraocular lens implantation after two weeks has less chances of postoperative endophthalmitis.

Abstract
OBJECTIVE To explored 6-month longitudinal changes in conjunctival colonisation and antibiotic resistance profiles of coagulase-negative Staphylococcus (CNS) after cataract surgery with 1 month tobramycin treatment. DESIGN Prospective cohort study between 1 August 2012, and 31 July 2013. SETTING A single medical centre in Taiwan. PARTICIPANTS A total of 128 Taiwanese patients with 46.9% of male participants. INTERVENTIONS Samples from the conjunctival sacs of both operation (OP) and non-OP eyes were obtained separately before cataract surgery and at 1, 3 and 6 months after surgery. Tobramycin (0.3%) treatment was applied four times daily for 1 month postoperatively. MAIN OUTCOME MEASURE Identification of CNS isolates and their antibiotic susceptibility by using disk diffusion or E-test. RESULTS CNS was detected in 24.2% of patients at baseline. During postoperative follow-up, the CNS colonisation rate did not decrease in either eye but showed an increasing trend in the OP eyes at 1 month (p=0.06). The colonisation rate showed no significant difference between the OP and non-OP eyes from baseline to a specific follow-up. We observed a significant increase (p<0.05) in resistance to tobramycin at 1 month and to ciprofloxacin at 3 months in the OP eyes and to trimethoprim/sulfamethoxazole at 1 month and 3 months and to oxacillin at 6 months in the non-OP eyes. CONCLUSIONS During the 6-month postoperative follow-up, 0.3% tobramycin administration failed to reduce CNS colonisation but increased resistance to several antibiotics. Postoperative antibiotic treatment may be replaced by other evidence-endorsed prophylactic routines.

Abstract
OBJECTIVE This study aimed to investigate the rates, types, and risk factors of surgical site infection (SSI) following spinal surgery using data from a Korean SSI surveillance system that included diagnoses made by surgeons. METHODS This was a prospective observational study of patients who underwent spinal surgeries at 42 hospitals in South Korea from January 2017 to December 2017. The procedures included spinal fusion, laminectomy, discectomy, and corpectomy. Univariate and multivariate logistic regression analyses were performed. RESULTS Of the 3080 cases included, 30 showed infection, and the overall SSI rate was 1.0% (an incidence of 1.2% in spinal fusion and 0.6% in laminectomy). Deep incisional infections were the most common type of SSIs (46.7%). Gram-positive bacteria caused 80% of the infections, and coagulase-negative staphylococci, including Staphylococcus epidermidis, accounted for 58% of the grampositive bacteria. A longer preoperative hospital stay was significantly associated with the incidence of SSI after both spinal fusion and laminectomy (p=0.013, p<0.001). A combined operation also was associated with SSI after laminectomy (p=0.032). CONCLUSION An SSI surveillance system is important for the accurate analysis of SSI. The incidence of SSI after spinal surgery assessed by a national surveillance system was 1.0%. Additional data collection will be needed in future studies to analyze SSI in spinal surgery.

Abstract
PURPOSE The aim of the study was to evaluate the bacterial contamination level of contact surfaces on slit lamps and the grip areas of lenses. METHODS Within unannounced audits, two regions of the slit lamps (headrest and joystick), indirect ophthalmoscopy devices, and ultrasound probes were obtained with rayon-tipped swab. Non-contact lenses used for indirect fundoscopy were pressed on RODAC (Replicate Organism Detection and Counting) plates. One hundred and eighty-one surfaces were sampled. The total number of colony-forming units was assessed and bacterial species were identified. Spa-typing and antimicrobial susceptibility testing were performed from Staphylococcus aureus isolates. RESULTS Among the total bacterial isolates from ophthalmological equipment (lenses: 51 of 78, slit lamps: 43 of 88, ophthalmoscopy helmets: 3 of 8, ultrasound probes: 2 of 7), coagulase-negative staphylococci (CNS) was most frequently found, followed by Micrococcus spp. (lenses vs. slit lamps: P < 0.001 and P = 0.01, respectively). The bacterial contamination of lenses (76%) was significantly higher than that of slit lamps (54%) (P < 0.003). A significantly higher contamination with CNS was observed on lenses from residents vs. from consultants (78% vs. 35%, P = 0.01). A total of seven different spa-types of S. aureus were isolated. No correlation was found between S. aureus contamination of different ophthalmological equipments (Spearman's rank correlation coefficient, ρ = 0.04, P = 0.75). Methicillin-resistant S. aureus was not detected. CONCLUSION Bacterial species of the normal skin flora were isolated from the ophthalmological equipment. The bacterial contamination of the portable devices was significantly higher than that of slit lamps. Therefore, proper hygiene of the mobile instruments should be monitored in order to prevent transmission of bacteria in residents and consultants.

Abstract
Purpose To evaluate the treatment outcomes of patients with post cataract surgery endophthalmitis in our tertiary referral center. Methods In this prospective study, patients with presumed post cataract surgery endophthalmitis were treated based on the modified endophthalmitis vitrectomy study (EVS) guidelines and followed for at least three months. Visual and anatomical outcomes were assessed in the last follow-up visit. Results A total of 46 eyes with presumed post cataract surgery endophthalmitis were admitted to our hospital, of which 3 eyes with initial visual acuity of no light perception (NLP) and severe inflammation underwent primary evisceration. Forty-three patients were included to this study and followed up for at least three months. Culture results were positive in 51.2% of cases and streptococcus viridans was the most frequent isolated organism. Pars plana vitrectomy was performed in 16 eyes as primary treatment, and intravitreal antibiotic injection was done in 27 eyes. Re-treatment with pars plana vitrectomy was required in 15 eyes (34.9%). Best corrected visual acuity (BCVA) at final visit was 20/40 or better in 12 eyes (27.9%), between 20/200 to 20/40 in 17 eyes (39.5%), and worse than 20/200 in 14 eyes (32.6%). Evisceration was done in one eye (2.3%), and retinal detachment happened in 4 eyes (9.3%). Conclusions The visual outcomes of post cataract surgery endophthalmitis are generally poor. Our results in this study were comparable with many previous studies from other referral centers, however, unlike many reports, streptococcus viridans was the most common isolate in our study.

Abstract
PURPOSE In this study, we investigated the associations between conjunctival (co) and intraocular (io) swabs and their implications for the contamination rates of organ-cultured corneas. METHODS A total of 4177 swabs from 1054 corneas of 527 donors were acquired from the conjunctiva, after disinfection with 5% polyvinylpyrrolidone-iodine solution, and also from the anterior chamber after corneoscleral trepanation (io). Samples were incubated at 22.5 ± 2.5°C and 32.5 ± 2.5°C in thioglycollate broth for 14 days. Donor corneas were cultured in a closed system at 31°C. Microbial differentiation was performed for positive cultures. RESULTS A higher temperature (32.5°C) and the intraocular swab retrieving localization led to significantly higher swab positive rates (32.5°C versus 22.5°C, odds 1.65, p < 0.0001; io versus co, odds 1,53, p < 0.0001). Death-to-collection time and laterality (left or right eye) had no significant influence on swab positivity. The cause of death significantly influenced the positive rates (p < 0.0001). Detection at 32.5°C occurred significantly earlier than at 22.5°C (p < 0.0001). The overall comparison of detected species showed no significant differences in the variety between intraocular and conjunctival swabs. During the study period, six contaminations of organ-cultured corneas occurred: four times Pseudomonas aeruginosa and once each Candida albicans and Staphylococcus hominis were found. Swap results and cornea contaminations were not significantly correlated. CONCLUSIONS Co and io swabs show high microbial colonization rates, even after standard disinfection. Io swabs generally reproduce the co microbial range, most likely due to a mobilization and diversion of microorganisms during the trepanation procedure. Swab results do not yield a valuable tool to predict contaminations of organ-cultured corneas.

Abstract
PURPOSE To review antibiotic resistance associated with S. aureus endophthalmitis and the virulence of S. aureus. METHODS Review of the current and prospective approaches for treating S. aureus endophthalmitis. RESULTS Bacterial endophthalmitis remains to be a major threat for vision. S. aureus endophthalmitis specifically, carries a poor visual prognosis making early diagnosis and treatment crucial. Methicillin resistant Staphylococcus aureus (MRSA) endophthalmitis represents a significant number of S. aureus endophthalmitis cases. MRSA with reduced susceptibility to glycopeptide antibiotics such as vancomycin (vancomycin intermediate S. aureus, VISA) have also emerged in the ocular infections, and there has been a rise in S. aureus resistance to new and old generation fluoroquinolones that are commonly used for prophylaxis after intravitreal injections and intraocular surgeries. CONCLUSIONS With the rise in the number of penetrating procedures in the ophthalmology practice and the parallel rise in antibiotic resistance, prophylaxis and awareness of the antimicrobial resistance profiles remain crucial and the identification of novel antimicrobials is essential.

Abstract
Endophthalmitis is one of the most feared complications after cataract surgery. The aim of this systematic review was to evaluate the effect of intracameral and topical antibiotics on the prevention of endophthalmitis after cataract surgery. A systematic literature review in the MEDLINE, CINAHL, Cochrane Library and EMBASE databases revealed one randomized trial and 17 observational studies concerning the prophylactic effect of intracameral antibiotic administration on the rate of endophthalmitis after cataract surgery. The effect of topical antibiotics on endophthalmitis rate was reported by one randomized trial and one observational study. The quality and design of the included studies were analysed using the Cochrane risk of bias tool. The quality of the evidence was evaluated using the GRADE approach. We found high-to-moderate quality evidence for a marked reduction in the risk of endophthalmitis with the use of intracameral antibiotic administration of cefazolin, cefuroxime and moxifloxacin, whereas no effect was found with the use of topical antibiotics or intracameral vancomycin. Endophthalmitis occurred on average in one of 2855 surgeries when intracameral antibiotics were used compared to one of 485 surgeries when intracameral antibiotics were not used. The relative risk (95% CI) of endophthalmitis was reduced to 0.12 (0.08; 0.18) when intracameral antibiotics were used. The difference was highly significant (p < 0.00001). Intracameral antibiotic therapy is the best choice for preventing endophthalmitis after cataract surgery. We did not find evidence to conclude that topical antibiotic therapy prevents endophthalmitis.

Abstract
PURPOSE To define global transcriptional responses of Staphylococcus aureus and its codY mutant (CodY is a transcription regulator of virulence and metabolic genes in response to branched-chain amino acids) when growing in bovine aqueous (AH) and vitreous humor (VH) in vitro, and to investigate the impact of codY deletion on S. aureus virulence in a novel murine anterior chamber (AC) infection model. METHODS For the in vitro model, differential transcriptomic gene expression of S. aureus and its codY mutant grown in chemically defined medium (CDM), AH, and VH was analyzed. Furthermore, the strains were inoculated into the AC of mice. Changes in bacterial growth, electroretinography and inflammation scores were monitored. RESULTS Bovine AH and VH provide sufficient nutrition for S. aureus growth in vitro. Transcriptome analysis identified 72 unique open reading frames differentially regulated ≥10-fold between CDM, AH, and VH. In the AC model, we found comparable growth of the codY mutant and wild type strains in vivo. Average inflammation scores and retinal function were significantly worse for codY mutant-infected eyes at 24 h post-infection. CONCLUSION Our in vitro bovine AH and VH models identified likely nutrient sources for S. aureus in the ocular milieu. The in vivo model suggests that control of branched-chain amino acid availability has therapeutic potential in limiting S. aureus endophthalmitis severity.

Abstract
PURPOSE Evidence of the transmission of disease via donor ocular tissue has been demonstrated for adenocarcinoma, rabies, hepatitis B virus, cytomegalovirus, herpes simplex virus, Creutzfeldt-Jakob disease, and a variety of bacterial and fungal infections. METHODS Although there is no evidence to date of disease transmission for HIV infection, syphilis, hepatitis C, hepatitis A, tuberculosis, HTLV-1 and -2 infection, active leprosy, active typhoid, smallpox, and active malaria, these entities remain contraindications for transplantation for all eye banks nationally and internationally. The potential sources of contamination include infected donors, during the process of removing tissue from cadaveric donors, the processing environment, and contaminated supplies and reagents used during processing. The transmissions of Herpes simplex virus and HSV via corneal graft have been shown to be responsible for primary graft failure. HSV-1 may also be an important cause of PFG. RESULTS The long latency period of some diseases, the emergence of new infectious disease, and the reemergence of others emphasize the need for long-term record maintenance and effective tracing capabilities. CONCLUSIONS The standardization of definitions for adverse events and reactions will be necessary to support the prevention and transmission of disease. International classification of a unique identification system for donors will be increasingly important for vigilance and traceability in cross-national exportation of human cells, tissues, and cellular- and tissue-based products. Opportunities for continuous improvement exist as does the need for constant vigilance and surveillance.

Abstract
Purpose: The purpose of this study was to investigate the causative organisms, the clinical characteristics, visual outcomes, and the incidence of acute endophthalmitis after cataract surgery. Materials and Methods: In this retrospective study, a chart review was performed for patients treated in a tertiary referral center for acute endophthalmitis after cataract surgery from January 2005 to December 2009. During the study period, 62 additional patients with acute postoperative endophthalmitis were referred to and treated in this center. Therefore the cohort comprised 70 patients (8 of whom underwent cataract surgery at our center, and 62 who were referred). Demographic, clinical, and laboratory data were analyzed. The primary outcome measure was final visual acuity. P<0.05 indicated statistical significance Results: During the study period, 7737 cataract surgeries were performed in this center. Eight (0.10%) of 7737 eyes developed acute postoperative endophthalmitis. Subgroup analysis indicated that extracapsular cataract extraction was associated with a fourfold higher risk of endophthalmitis compared with phacoemulsification. We found better initial visual acuity (VA) (≥ hand motion) (P<0.001) and negative cultures (P=0.021) were independently associated with a more favorable visual outcome. Patients with relative afferent papillary defect (RAPD) were associated with lower initial VA (P<0.001) and worse visual outcome (P=0.001). Positive microbial cultures were found for 33 (42.9%) cases. Staphylococcus aureus was the most common organism isolated. Positive cultures were more frequently found in patients with RAPD. The “gram-positive coagulase-negative” and “no growth” groups had the best visual outcome. Associated keratitis and avoiding intraocular steroids were associated with the risk of evisceration. Conclusion: The visual outcome after endophthalmitis was generally poor and only one eighth of the eyes achieved a final corrected visual acuity of ≥20/200. Therefore, better treatment strategies are warranted. Immediate treatment is essential and the role of primary vitrectomy requires further investigation. In addition, RAPD, as an objective test, may complement VA for predicting the prognosis and planning the course of treatment.

Abstract
PURPOSE To evaluate the efficacy of adding either linezolid or daptomycin to Optisol-GS donor storage medium in reducing methicillin-resistant Staphylococcus aureus (MRSA) contamination of donor corneas. METHODS Optisol-GS was supplemented with either linezolid at 2×, 4×, or 10× minimum inhibitory concentration (MIC) or daptomycin and calcium at 5× or 50× MIC. Unsupplemented control groups were also used. Gentamicin-sensitive and gentamicin-resistant isolates of MRSA were added, and vials were refrigerated for 48 hours followed by sampling for viable colony counts immediately upon removal from refrigeration and after warming to room temperature for 3 hours. Safety studies of Optisol-GS supplemented with 50× MIC daptomycin and calcium were performed by evaluating the central corneal thickness and endothelial cell density of the donor cornea. Stability of daptomycin in Optisol-GS at storage was also tested. RESULTS No added benefit was observed with linezolid supplementation to Optisol-GS against gentamicin-sensitive MRSA, with reduction in viable colony counts by >90% in all groups. No benefit was observed with linezolid supplementation against gentamicin-resistant MRSA, with the majority of inocula remaining viable in all groups. Viable counts of gentamicin-sensitive MRSA and gentamicin-resistant MRSA were effectively reduced with both 5× MIC and 50× MIC daptomycin supplementation. 50× MIC daptomycin-supplemented Optisol-GS had no appreciable effect on the central corneal thickness or endothelial cell density of the donor cornea and was stable at storage for 14 days. CONCLUSIONS The addition of daptomycin to Optisol-GS significantly increases the anti-MRSA activity of the medium without any apparent negative effects on donor corneal tissue.

Abstract
PURPOSE To determine by microbiological examinations the rate of conjunctiva and corneoscleral rim contamination of cadaver donor tissues. METHODS A prospective review of culture results for 98 cadaver donor conjunctival swabs [mean age 76.4 ± 12.9 years (±SD)]. Transplant patients were evaluated both before and after disinfection with gentamicin. Individual parameters evaluated included detection rates of bacteria, variety of detected bacteria, time interval from donor death to tissue harvest and age of donors. RESULTS Before disinfection, 60 out of 98 conjunctival swabs exhibited microbial growth, while only 36 out of 98 exhibited growth after disinfection (p = 0.0006). Longer intervals between death and tissue harvest were associated with higher positive microbial growth rates. Prior to disinfection, culture-positive donors (74.1 ± 13.6 years) were significantly younger than culture-negative donors (79.8 ± 10.8 years) (p = 0.024). Positive donor rim cultures were noted in 2 out of the 22 corneal transplantations. Microorganisms isolated from the corneal grafts matched those found in the conjunctiva. CONCLUSIONS It is recommended that the corneoscleral buttons be removed as soon as possible. Cultures of conjunctival swabs collected from donors after disinfection may be useful in determining treatment for postoperative infections occurring after corneal transplantation.

Abstract
OBJECTIVE The aim of the study was to assess the functional results and long-term visual prognosis in patients treated for acute endophthalmitis (AE). DESIGN Observational clinical series. PARTICIPANTS Evaluation of 120 eyes of 114 patients with AE treated between 1991 and 2004. METHODS This retrospective institutional analysis included 120 eyes of 114 patients (52 male, 68 female) with AE and a minimum follow-up of half a year. The patients had a mean follow-up of 23 months (6-135 months) and a mean age of 61 years (8 months-94 years) at the time of treatment. Treatment included intraocular injection of antibiotics alone (n = 18, 15%) and vitrectomy combined with intraocular and topical postoperative antibiotics (n = 85, 70%). RESULTS The most frequent complications were vitreous or retinal hemorrhages (n = 17, 14%), retinal detachment (n = 17, 14%), choroidal detachment (n = 3, 3%), secondary glaucoma (n = 7, 6%), and recurrent endophthalmitis (n = 3, 3%). Four eyes had to be enucleated because of recurrent and uncontrollable infection. Positive microbiological results were achieved in 67 of 88 specimens (76%). The most common isolate was Staphylococcus. At the end of follow-up, visual acuity was reduced (more than 2 lines) in 18 eyes (15%), stable in 22 (18%), and improved (more than 2 lines) in 72 eyes (60%). CONCLUSIONS AE is a rare but severe disease with a potentially deleterious outcome in affected eyes. In our series, 78% of all eyes had stable or improved postoperative visual acuity following various treatment regimens, depending on the severity of each case.

Abstract
PURPOSE The aim of this study is to determine if postoperative endophthalmitis adversely affects quality of life after cataract surgery. METHODS We compared quality of life in patients who developed endophthalmitis after cataract surgery between 1 January and 31 December 2003 with those who had uncomplicated surgery. The National Eye Institute VFQ-25 (VFQ-25) and EuroQol EQ-5D (EQ-5D) questionnaires and time trade-off utility scores were used to compare self-perceived general health and vision-related quality of life between groups. Linear regression was used to model differences between groups after adjusting for age, gender and visual acuity in the better eye. RESULTS Nineteen postoperative endophthalmitis cases were compared with 30 who had uncomplicated cataract surgery. Following surgery the mean composite VFQ-25 score was 13.5% (95% confidence interval [CI]: 6.0-26.4, P < 0.01) lower in endophthalmitis cases. Endophthalmitis patients reported significantly lower (P < 0.05) general vision, near vision, peripheral vision, mental health and role difficulties subscales scores after adjusting for age, sex and visual acuity. No significant differences were found in other subscales. Mean time trade-off utility and all EQ-5D scores were similar except for mobility (95% CI: 0.04-0.68, P < 0.05). CONCLUSIONS Endophthalmitis after cataract surgery negatively impacts on self-perceived vision-related quality of life, resulting in poorer psychological well-being and ability to maintain a role in daily life.

Abstract
PURPOSE To report a large, consecutive series of endophthalmitis of all causes managed at a tertiary referral retina center. METHODS Retrospective chart review of all cases diagnosed with endophthalmitis that received reatment and follow-up between January 2000 and January 2005. RESULTS A total of 67 patients were diagnosed with endophthalmitis. The most common cause was postoperative endopthalmitis after cataract surgery. Initial management was vitreous needle biopsy with intravitreal antimicrobial injection in a majority of cases (79%). Vitreous cultures were positive in 32 eyes (44.4%); the most common isolate was coagulase negative Staphylococci. Final visual acuity was improved in 61% of patients. More than a third (38%) had vision worse than count fingers. Twenty-eight eyes (39%) needed pars plana vitrectomy for secondary complications as a consequence of endophthalmitis. CONCLUSIONS Cataract surgery remains the most common cause of endophthalmitis in this large tertiary referral retina center. Endophthalmitis resolved with vitreous needle biopsy and intravitreal injections in more than half of the cases. However, more than a third of patients required additional vitreoretinal surgery for secondary complications. More than a third of patients had nonfunctional vision after the resolution of endophthalmitis, which highlights the severity of this condition in the current expanding era of office-based intravitreal pharmacotherapy for retinal diseases.
