ABSTRACT

OBJECTIVE: To evaluate the relationship between the microbiological results of the vitreous humor and those of foreign body specimens in patients with intraocular foreign body (IOFB). METHODS: Seventy-one patients with an IOFB were included in this descriptive prospective case series. All patients underwent immediate IOFB removal. Vitreous sampling was performed during vitrectomy. Foreign bodies were placed directly into culture media for microbiological study. RESULTS: Thirteen (18.3%) patients developed endophthalmitis. The results of microbiological analysis of IOFB and vitreous humor specimens were negative in nine patients and positive in four. Fifty-eight (81.6%) patients with an IOFB had no evidence of endophthalmitis. Among them, seven patients showed positive microbiological results of foreign bodies with no manifestations of endophthalmitis. In five patients, a Staphylococcus epidermidis strain was observed in the culture of the IOFB specimen. Two patients had only positive smear test results of their vitreous humor specimen. CONCLUSION: A correlation appears to be present between the microbiological results of the vitreous humor and IOFB specimens in patients with clinical findings of endophthalmitis but not in patients with a pure IOFB without clinical features of endophthalmitis. This may justify early use of intravitreal and intravenous antibiotics before the development of endophthalmitis.

ABSTRACT

PURPOSE: To report the laboratory findings, management strategies, and visual outcomes of culture-proven exogenous fungal endophthalmitis in North China. METHODS: The microbiological and treatment records of patients with culture-positive exogenous fungal endophthalmitis who visited the Affiliated Hospital of Qingdao University from January 2012 to December 2016 were reviewed. RESULTS: A total of 39 eyes (39 patients) were identified over a 5-year period. Exogenous fungal endophthalmitis was associated with penetrating trauma in 22 eyes (56.4%), fungal keratitis in 15 eyes (38.5%), and intraocular surgery in 2 eyes (5.1%). Hyphae were found in 29 of 37 smear samples (78.4%) by direct microscopic examination. Fungal pathogens cultured from 39 samples were identified as 10 genera and 15 species. Filamentous fungi (molds) accounted for 94.9% (37 samples), including Fusarium (19, 48.7%) and Aspergillus (11, 28.2%). Most keratitis cases were caused by Fusarium (11 of 15; 73.3 %). Aspergillus was isolated from nine penetrating ocular trauma cases (9 of 22; 40.9%). Three eyes receiving evisceration had fungal and bacteria coinfection (3 of 39, 7.7%) with Aspergillus and Bacillus. At least, one surgical intervention was performed in all 39 eyes and 28 (71.8%) eyes underwent two or more procedures, including surgeries and intraocular injections. Twenty-nine patients received intraocular antifungal therapy with amphotericin B and/or voriconazole. Visual acuity at discharge from the hospital was significantly better than the initial visual acuity (p < 0.001). Final vision of 20/400 or better was achieved in 22 (56.4%) eyes. CONCLUSIONS: This study highlighted the differences between clinical categories of exogenous fungal endophthalmitis. Trauma was the major etiological factor. Molds were the most common pathogens, with Fusarium ranking first, followed by Aspergillus. Fungal and bacterial coinfection mostly occurred after metal penetrating trauma, and Bacillus was the primary bacterial pathogen. Coinfection may be one reason of evisceration. Immediate intravitreal antifungal therapy combined with vitrectomy was effective for exogenous fungal endophthalmitis. Amphotericin B and voriconazole were commonly used antifungal agents.

ABSTRACT

BACKGROUND: Localized `and disseminated Nocardia farcinica infection is frequently reported in immunocompromised patients. However, orbital nocardiosis is rare, and, to our knowledge, traumatic orbital nocardiosis that affects the brain has never been described. Here, we report a case of traumatic orbital and intracranial N. farcinica infection in an immunocompetent patient. CASE PRESENTATION: A 35-year-old man, who was immunocompetent, to the best of our knowledge and as per the absence of immunodeficiency symptoms, with orbital trauma caused by the penetration of a rotten bamboo branch developed lesions in the orbit and brain. Subsequently, he underwent debridement and received broad-spectrum antibiotic therapy, but orbital infection occurred, with drainage of pus through the sinus tract. The patient then underwent endoscope-assisted local debridement. Bacterial culture of the sinusal pus was positive for N. farcinica, and a combined intracranial infection had developed. The disease was treated effectively by trimethoprim-sulfamethoxazole and ceftriaxone sodium therapy. The patient remained infection free and without complications at the 14-month follow-up. CONCLUSIONS: Traumatic orbital and intracranial infection caused by N. farcinica is a rare infectious disease, and atypical presentations easily lead to misdiagnosis. When a patient presents with an atypical orbital infection that is unresponsive to empirical broad-spectrum antibiotics, along with suspicious neurologic symptoms, Nocardia infection should be considered. Identification by bacterial culture is the gold standard. Complete local debridement and appropriate antibiotic treatment are keys to the treatment of the disease.

ABSTRACT

BACKGROUND: We present a case of post-traumatic endophthalmitis with relatively good prognosis caused by Gordonia sputi, which, to our knowledge is the first case in the literature. CASE PRESENTATION: A 24 year old man, who underwent an intraocular foreign body extraction half a month before presentation in the left eye, was referred to us complaining of blurred vision and slight pain for 5 days. His first presentation showed moderate intracameral and intravitreous purulent inflammation with a best corrected vision of counting fingers. After gram staining of the intravitreous samples revealed a gram-positive bacilli infection, a combination of amikacin and vancomycin was initially injected intravitreously. The left eye kept stable for three days but deteriorated on the 4th day. On the 5th day after presentation conventional culture characterized the bacterium as an Actinomyces sp. while 16S ribosomal RNA gene sequencing confirmed it as Gordonia sputi. Thereby a complete pars plana vitrectomy combined with lensectomy and silicone oil tamponade was performed. During the surgery an intraocular irrigation with penicillin G was adopted, followed by administration of intravenous penicillin G twice one day for a week. A relatively normal fundus with slight intracameral inflammation was observed a week after the operation, and the best corrected vision recovered to 0.15. One year later his vision remained 0.1. CONCLUSION: Gordonia sputi should be taken into consideration in patients with post-traumatic endophthalmitis especially due to foreign body penetration. Compared to conventional laboratories, molecular methods are recommended for an accurate diagnosis. A comprehensive strategy of antimicrobial agents and vitrectomy may render a satisfactory result.

ABSTRACT

BACKGROUND: Pediatric infectious endophthalmitis is a serious sight-threatening disease for children. The purpose of this study was to investigate the etiology, microbiological spectrum, and visual outcomes of infectious endophthalmitis in children at a single institution in China. METHODS: It is a retrospective study of the medical records of all patients under 14 years of age with histories of infectious endophthalmitis, treated at a single institution from January 1, 2009 to January 1, 2015. The clinical characteristics, etiology, microbiological spectrum, and management, as well as the visual outcomes, were analyzed. The Kappa test and Chi-square test were used in the statistical evaluation. RESULTS: A total of 271 children were identified, with a mean age of 5.61 ± 2.93 years (range 5 months to 14 years). Ocular trauma (94.8%) and previous ocular surgery (3.0%) were the most common etiologies. Overall, 147 (54.2%) cases had positive cultures, and 176 organisms were isolated from these patients. A single species was isolated in 120 (81.6%) cases, with multiple organisms in 27 (18.4%) cases, and the most commonly identified organisms were coagulase-negative Staphylococcus and Streptococcus species, comprising 29.5% and 26.8% of the isolates, respectively. Moreover, of 176 isolates, 142 (80.8%) were Gram-positive organisms, 23 (13.0%) were Gram-negative organisms, and 11 (6.2%) were fungi. The final visual outcomes were 20/200 or better in 66 (24.4%) eyes, counting fingers to 20/200 in 34 (12.5%), hand motions in 30 (11.1%), light perception in 33 (12.2%), no light perception in 32 (11.8%), and 9 (3.3%) eyes were enucleated or eviscerated. The visual outcomes were not available in 67 (24.7%) patients. CONCLUSIONS: Penetrating ocular trauma is the most frequent cause of pediatric endophthalmitis in China. Streptococcus and Staphylococcus species are the most commonly identified organisms in exogenous pediatric endophthalmitis whereas Fusarium species are commonly seen in endogenous endophthalmitis. In this research, in spite of aggressive management with antibiotics and vitrectomy, the visual prognosis was found to be generally poor.

ABSTRACT

BACKGROUND: To identify the etiology, pars plana vitrectomy results, culture results, and visual outcome of endophthalmitis in the pediatric age group. METHODS: Fifteen eyes of 15 consecutive pediatric patients who were treated and followed up for endophthalmitis between July 2011 and December 2012 were included in this study. Combined pars plana vitrectomy and intravitreal norvancomycin plus ceftazidime injection was performed on all 15 eyes. The vitreous samples were obtained by a standard pars plana vitrectomy. The specimens were sent to microbiology facility for gram staining, culturing, and sensitivity testing. RESULTS: The mean age of the patients was 5.3 ± 2.8 years (3-10 years). The mean follow-up time was 9.7 ± 1.5 months (7-12 months). Preoperatively, the visual acuities of the patients were as follows: light perception (n = 7), hand movements (n = 4), and counting fingers from 30 cm (n = 1), and these values were not available in three patients (n = 3). Postoperatively, the final best corrected visual acuity was 20/200 or better in six (40 %), counting of fingers in four (26.7 %), light perception to hand movements in two (13.3 %), and no light perception in one (6.7 %), with results being unavailable for two patients. Positive culture results were obtained from ten eyes (66.7 %). A single species was isolated in eight eyes, and multiple organisms were isolated in two eyes. CONCLUSIONS: Penetrating ocular trauma was the most common cause of pediatric endophthalmitis in this consecutive series of endophthalmitis. Staphylococci and Streptococcus species were the most common isolated organisms. Patients with multiple organisms had poor visual recovery. Visual outcomes were poor in this series in spite of vitrectomy being performed immediately on all patients.

ABSTRACT

PURPOSE: The purpose of this study was to describe clinical features, risk factors, causative organisms, treatment options, and outcomes of post-traumatic endophthalmitis in children and adolescents. METHODS: Retrospective interventional case series. Case records of 143 consecutive eyes presenting with post-traumatic endophthalmitis between 1997 and 2007 were reviewed. Univariate and multivariate analysis were done to analyze factors associated with adverse outcomes. RESULTS: Mean age at presentation was 9.2 years (median 8 years, range: 2 months to 18 years). Broomstick and hypodermic needle were most common causes for injuries. Common presenting features were cataract (n=51), hypopyon (n=45) and retinal detachment (n=29). Corneal abscess (n=21; OR: 5, CI: 1.4-18.7) and retinal detachment (n=29, OR: 5, CI: 1.6-11.3) were independent risk factors for poor outcome (P=0.04 and 0.012, respectively). Gram-positive bacteria were isolated in 54% (n=31) of culture-positive cases. Forty-nine (34%) patients had ambulatory vision at final visit. Patients who received treatment within 24 h were 3.6 and 9 times more likely to have better anatomical outcome than those treated at 2-7 days, or >7 days, respectively (P=0.0001). Patients undergoing early vitrectomy were 27 times more likely to have better outcome (P=0.0001). CONCLUSION: Post-traumatic endophthalmitis in children is more common in boys <10 years of age and most often caused by injury with organic matter. Corneal abscess and retinal detachment are associated with poor outcome. E. fecalis is the most common causative organism. Early vitrectomy results in better outcomes.

ABSTRACT

Post-traumatic endophthalmitis (PTE) is an uncommon sequela of open globe injuries. In cases involving an intraocular foreign body (IOFB), the risk of PTE increases by up to four-fold. Typically, presentation occurs in the acute timeframe. Only three reported cases of delayed-onset PTE currently exist in the literature (two cases caused by Proprionibacterium acnes and one by Phaeoacremonium parasiticum, a fungal pathogen). We describe a case of delayed-onset post-traumatic endophthalmitis (PTE) caused by Lysinibacillus spp., an organism not previously reported in the ophthalmic literature.

ABSTRACT

Post-traumatic endophthalmitis comprises 25-30% of all endophthalmitis cases. Post-traumatic endophthalmitis is an important clinical condition that may have serious anatomical and functional consequences. The type of pathogenic microorganism, nature of the injury, the presence of a foreign body, and the geographical region in which the trauma occurred are all important factors influencing both treatment and prognosis. Unlike postoperative endophthalmitis, there is not a confirmed treatment protocol recommended by the Endophthalmitis-Vitrectomy Study Group in traumatic cases. In this study, we examine the incidence, risk factors, diagnosis, microbiological features, and treatment principles of post-traumatic endophthalmitis in order to guide clinicians who often encounter eye trauma related to this potential complication.

ABSTRACT

PURPOSE: To determine whether penetrating scleral or corneal injury can enhance intraocular penetration of systemic moxifloxacin, vancomycin, and ceftazidime. METHODS: Thirty rabbits were divided into 3 groups for each antibiotic and then further subdivided to receive either scleral or corneal injury to the right eye. The left eye served as a control. Intravenous antibiotics were given following injury, and eyes were subsequently enucleated. Vitreous antibiotic concentration was determined by high-performance liquid chromatography analysis. Plasma concentration was measured for comparison. RESULTS: Intravitreal moxifloxacin concentration was unchanged by injury. Minimum inhibitory concentration (MIC90) was achieved in the vitreous against the most common gram-positive endophthalmitis-causing organisms. Intravitreal vancomycin levels were not enhanced by injury and did not reach the MIC90 for gram-positive organisms commonly causing intraocular infection. Intravitreal ceftazidime was increased in the injured eyes, 67% and 73% higher in scleral and corneal injury eyes. It reached MIC90 of many gram-negative bacteria. CONCLUSIONS: Intravitreal antibiotic penetration of systemic antibiotics with or without penetrating ocular injury varies depending on the antibiotic. For prevention or treatment of gram-positive-bacteria-causing endophthalmitis, intravitreal vancomycin is necessary and provides the most reliable coverage. Systemic ceftazidime can be used for many gram-negative bacteria, but intravitreal injection is recommended for better coverage, especially for more-potent organisms. Systemic moxifloxacin can be considered for most gram-positive and -negative infections due to its excellent intraocular penetration and broad coverage, but the patient's previous history of its topical use and increasing resistance patterns must be considered.

ABSTRACT

PURPOSE: To profile the etiology, clinical outcomes and drug sensitivity patterns in endophthalmitis caused by Acinetobacter baumanni. METHODS: Retrospective analysis of all the cases of Acinetobacter baumanni endophthalmitis presenting to tertiary referral care ophthalmic hospital in Eastern India from January 2009 to December 2011 were done. RESULTS: A total of four cases were included in the study. Out of the four cases one was post traumatic and the rest were post cataract surgery. All the cases underwent vitreoretinal surgical intervention followed by intravitreal antibiotics. A. Baumanni was isolated from vitreous in all the cases. Among all the drugs tested bacteria were found sensitive to ciprofloxacin (100 %) whereas all tested resistant to ceftazidime. Out of the four cases one had to be eviscerated, another developed retinal detachment post vitrectomy, one was phthisical at final followup, and only one patient achieved a vision of 20/200 with clear media and attached retina at final visit. CONCLUSION: A. Baumanni is a very rare cause of endophthalmitis with poor visual and anatomical outcomes. Ciprofloxacin should be considered as first the line intravitreal antibiotic.

ABSTRACT

PURPOSE: Study the clinical and microbiological characteristics and the prognostic factors of post-traumatic endophthalmitis. METHODS: Seventeen eyes were included between 2004 and 2010, with clinical and microbiological data collected prospectively. Conventional cultures and panbacterial PCR were performed on aqueous and vitreous samples. RESULTS: Clinical signs of endophthalmitis were observed soon after trauma (1.5 ± 2.5 days). Laceration with an intraocular foreign body (IOFB) was noted in 53% of the patients. At admission, all patients had aqueous humour (71%) and/or vitreous (53%) samples. Fifteen patients (88%) underwent a pars plana vitrectomy. Bacteria were identified in 77% of the cases: Staphylococcus epidermidis (n = 5), Streptococcus (n = 4), Bacillus (n = 2), Pseudomonas stuzeri (n = 1), and Streptococcus salivarius and Gemella haemolysans (multibacterial infection, n = 1). Progression toward phthisis was observed in 35% of the cases; 41% of the patients recuperated visual acuity (VA) ≥20/40. A good final visual prognosis (≥20/40) was significantly associated with initial VA better than light perception (0% versus 70%, p = 0.01) and absence of pupillary fibrin membrane (80% versus 20%, p = 0.05). There was no correlation between visual prognosis and age, the type of laceration (corneal or scleral) or presence of an IOFB. We found a statistical trend toward an association between bacterial virulence and poor final VA. CONCLUSION: This series showed that better final VA outcomes were associated with initial VA better than light perception, S. epidermidis or culture-negative cases and absence of retinal detachment during the clinical course.

ABSTRACT

PURPOSE: To report the occurrence of periorbital infections in 3 children treated with the tissue adhesive 2-octyl cyanoacrylate (Dermabond) after traumatic periorbital laceration. METHODS: We retrospectively reviewed the records of consecutive patients referred to Vanderbilt Children's Hospital for the treatment of periorbital infections to identify cases associated with the use of Dermabond. The clinical features and outcomes of each case were reviewed. We performed a meta-analysis of published cases to identify any association of tissue adhesive with wound infection rate. RESULTS: The review identified 3 patients, all of whom were younger than 3 years of age and developed cellulitis within 24 hours of wound closure. Broad-spectrum intravenous antibiotic therapy was started in less than 3 hours in all cases. Cultures were obtained in 2 of the 3 cases; both grew Streptococcus pyogenes. Two cases required surgical intervention, including one with necrotizing fasciitis. In the meta-analysis, the wound infection rate was 1.8% in tissue adhesive closure and 0.3% in standard wound closure (odds ratio 6.0; 95% confidence interval 0.7-50.3, P = 0.06). CONCLUSIONS: The development of periorbital cellulitis after the closure of periorbital lacerations with Dermabond should alert the physician to the possibility of periorbital infection, including necrotizing fasciitis. The literature review suggests a trend toward an increased infection rate with tissue adhesive closure. We propose that ineffective wound sterilization before tissue adhesive wound closure may be a contributing factor.

ABSTRACT

INTRODUCTION: Endophthalmitis is the most dreaded complication of ocular trauma and knowledge of the microbial contaminants is essential to start empirical antibiotic therapy. PURPOSE: To determine incidence of contamination after open globe injuries (OGI) in our setup and to identify the spectrum of microorganisms contaminating open globe injuries. MATERIAL AND METHODS: A prospective study including 50 consecutive eyes of open globe injury over a period of two years was conducted. Intra-operatively, 4 - 5 samples were taken from the inferior conjunctival sac and anterior chamber at the beginning and end of the open globe injury repair. Any abscised tissue or foreign body was also sent for culture sensitivity. A vitreous tap was taken from eyes with posterior segment trauma with signs of endophthalmitis. RESULTS: Microbial cultures were positive in13 eyes (26 %). The microbial spectrum included Aspergillus species in 45.6 %, Alternaria in 15.2 %, Curvularia in 15.2 %, Staphylococcus aureus in 7.6 %, Bacillus species in 7.6 %, and Streptococcus pneumoniae in 7.6 %. Of these 13 eyes, nine eyes developed clinically evident frank endophthalmitis during follow-up. Overall, endophthalmitis developed in 20 eyes (40 %). There was a significant association between the initial contamination and development of endophthalmitis (p less than 0.05). 53 % of culture positive cases achieved ambulatory vision compared to 73 % of culture-negative cases. CONCLUSION: Initial contamination was seen in 26 % of OGI cases. Aspergillus (fungus) was the commonest contaminant. There was a strong correlation between the initial contamination and development of endophthalmitis. Culture-negative cases had a trend towards better final visual outcome than culture-positive cases. Close follow up of cases showing contamination following OGI is recommended.

ABSTRACT

BACKGROUND AND OBJECTIVE: The authors investigate clinical settings, antibiotic susceptibility and resistance patterns, and visual outcomes associated with endophthalmitis caused by Stenotrophomonas maltophilia. PATIENTS AND METHODS: Records of six patients with S. maltophilia endophthalmitis between January 1, 1998, and December 31, 2007, were reviewed. RESULTS: Clinical settings included post-trauma (2 eyes), post-cataract extraction (2 eyes), post-keratoplasty with keratitis (1 eye), and post-vitreous lavage (1 eye). Presenting visual acuity ranged from counting fingers to no light perception. Final visual acuity ranged from 10/20 to no light perception. Initial treatment included pars plana vitrectomy in 4 eyes and tap in 2 eyes. Most isolates were susceptible to fluoroquinolones (ciprofloxacin, levofloxacin, or moxifloxacin) and sulfamethoxazole-trimethoprim; however, they were resistant to ceftazidime and aminoglycosides. CONCLUSION: S. maltophilia is an uncommon causative agent of endophthalmitis and is resistant to commonly used antibiotics, such as ceftazidime and aminoglycosides. Based on in vitro antibiotic susceptibility testing, sulfamethoxazole-trimethoprim and new-generation fluoroquinolones may be preferable in the treatment of endophthalmitis caused by S. maltophilia.

ABSTRACT

PURPOSE: Our aim was to evaluate the incidence, risk factors, pathogens, use of systemic and intravitreal antibiotics, and outcome of traumatic endophthalmitis after open globe injury with retained intraocular foreign body (RIOFB). METHODS: Patients with open globe injury and RIOFB complicated by endophthalmitis were enrolled and retrospectively studied in Taiwan over a 20-year-period from 1981 to 2002. RESULTS: There were 125 patients, who sustained open globe injury and RIOFB, which required surgical management. In 15 patients (12%) traumatic endophthalmitis was identified. Thirteen (87%) of these 15 cases had signs of endophthalmitis at their initial presentation. The patients' mean age was 41 years; all of them were male. Invading micro-organisms were isolated in 8 patients, and the positive culture rate was 53%. Gram-negative bacteria were the most commonly isolated organisms in 6 patients and 1 eye with multiple organisms. One eye with culture-proven Bacillus cereus had a very fulminant course and ended with phthisis bulbi. All 15 patients received topical and systemic intravenous antibiotic treatment; 9 eyes (60%) were given intravitreal antibiotic injection with broad-spectrum combined vancomycin and ceftazidime in 5 eyes. Pars plana vitrectomy was performed in 9 patients, with successful removal of RIOFB. The final visual acuity improved in 8 patients (53.5%), was unchanged in 1 (6.7%) and worse in 6 (40.0%). Five patients (33%) got a visual outcome of 6/60 or better. There were also 5 patients (33%) with a poor outcome of no light perception. Eleven (73%) of 15 patients had treatment delayed for >24 h after injury, and 5 out of these 11 patients had a very poor visual outcome (1 hand motion, 4 no light perception). Delay of presentation for >24 h after injury was associated with a tendency to increased risk of endophthalmitis [11/71 (15.5%) vs. 4/54 (7.4%)]. CONCLUSIONS: Early intravitreal antibiotics and prompt vitrectomy to remove the contaminating IOFB may salvage useful vision in some patients with traumatic endophthalmitis with RIOFB. Delay of treatment for >24 h was associated with increased risk of traumatic endophthalmitis.

ABSTRACT

BACKGROUND: Many cases of post-operative and posttraumatic endophthalmitis are being managed at the Khyber Institute of Ophthalmic Medical Sciences, Peshawar in Pakistan but no study has been done to ascertain the magnitude of the disease and to also evaluate the visual outcome after management. METHODS: The case notes of 39 patients diagnosed with posttraumatic and postoperative endophthalmitis between May 2006 and April 2007 were analyzed and clinical characteristics obtained were documented and tabulated. RESULTS: During the study period, 2474 patients were admitted in both the male and female wards. Of these, 39 (1.6%) had endophthalmitis due to surgical and traumatic complications. In all, 6 (12.4%) patients had evisceration, while 21 (53.8%) patients who had topical antibiotics consisting of ofloxacin, 0.1% corticosteroids, fortified cetazoline and 1% atropine along with intravitreal antibiotics, a combination of 0.1 mg vancomycin and 0.4 mg amikacin, were discharged home with a visual acuity of counting fingers to light perception. CONCLUSION: Endophthalmitis is a serious ocular complication of open globe injury and intraocular surgery. The frequency in this center has been noted to be very high as compared to other places. Its management is very challenging and often leads to devastating structural and functional damage to the eye; causing severe frustration to both the patient and the attending physician. Efforts must be made to prevent the condition.
