Role of prophylactic intravitreal antibiotics in open globe injuries

PURPOSE: To determine the efficacy of prophylactic intravitreal antibiotics in reducing the incidence of endophthalmitis after trauma. METHODS: This was a prospective, randomised, case control study of 70 consecutive patients with open globe injury. The patients were prospectively randomised into group I (32 eyes) and group II (38 eyes). Group I patients were given prophylactic intravitreal injection of vancomycin 1 mg and ceftazidime 2.25 mg at the conclusion of primary repair. Group II patients were not given prophylactic intravitreal antibiotics. All the patients received intravenous ciprofloxacin. RESULTS: The incidence of endophthalmitis was higher in group II (7 of 38 eyes; 18.42%) compared to group I (2 of 32 eyes; 6.25%). Both the patients who developed endophthalmitis despite prophylactic intravitreal antibiotics in group I had an initially undetected intraocular foreign body (eyelash) in the vitreous cavity. CONCLUSIONS: Prophylactic intravitreal broad spectrum antibiotic injection decreases the risk of post-traumatic endophthalmitis.

Vitrectomy for the treatment of posttraumatic endophthalmitis

AIM: To evaluate the efficacy of vitrectomy in combination with intravitreal dexamethasone and vancomycin perfusion in the management of severe posttraumatic endophthalmitis. · METHODS: Thirty eyes of 30 cases diagnosed as posttraumatic infectious endophthalmitis were analyzed retrospectively from April 2004 to April 2006. All the patients underwent vitrectomy in combination with intravitreal drugs perfusion and were followed up for 12 to 24 weeks. The visual acuity, traumatic causes and microorganisms culture were analyzed. · RESULTS: There are significant reduction in inflammation at 3 months after surgery. Infectious symptoms were completely controlled in 97% of the cases(29/30). Final visual acuity were improved in 93% of cases (28/30). Among traumatic causes, foreign body is the most common cause (57%). Staphylococcus aureus is the commonest microorganism. · CONCLUSION: Vitrectomy in combination with intravitreal dexamethasone and vancomycin perfusion is the most effective method in the treatment of severe posttraumatic endophthalmitis.     

Pars plana vitrectomy with or without silicone oil endotamponade in post-traumatic endophthalmitis

BACKGROUND: Results of core vitrectomy in post-traumatic endophthalmitis are poor. Our initial results of complete vitrectomy with primary silicone oil endotamponade were promising. A comparative study of this procedure with conventional core vitrectomy was therefore carried out. METHODS: A prospective randomized controlled study of 24 consecutive cases of post-traumatic endophthalmitis was conducted. Patients were randomized into two groups in the absence of clinical improvement after primary tap and treatment with intravitreal vancomycin and amikacin: group 1 consisted of patients who underwent core vitrectomy alone, group 2 of patients who underwent complete vitrectomy with silicone oil endotamponade. All patients included in the study received intravenous antibiotics and underwent lensectomy. Patients were followed up 1, 2, 4 and 12 weeks postoperatively. In all patients of group 2, silicone oil was removed 6 weeks after primary surgery. The mean duration of follow-up was 112+/-55 days. RESULTS: Vision of 20/400 or better was obtained in 58.33% of cases (14/24). Visual acuity of only one patient in group 1 was >or=20/200, compared with that of 58.3% of patients (7/12) in group 2 ( P=0.02). Intra-operative retinal breaks were found in 50% (6/12) of the patients belonging to group 1, but did not affect the final visual outcome. In group 1, 33.33% (4/12) developed rhegmatogenous retinal detachment in the immediate post-operative period. Only one of these patients had useful final visual outcome after resurgery. CONCLUSION: Complete vitrectomy with primary silicone oil endotamponade is a useful treatment modality which improves the anatomical and functional results in post-traumatic endophthalmitis.     

Acute postoperative endophthalmitis by Gemella haemolysans

Endophthalmitis is a rare and serious post-surgical complication. We report a case of acute postoperative endophthalmitis after an uneventful cataract surgery caused by a commensal organism, Gemella haemolysans. The patient was successfully treated with vitrectomy and intravitreal antibiotics like vancomycin, along with topical cefazolin.     

Group B Streptococcus endogenous endophthalmitis : case reports and review of the literature

PURPOSE: To report five cases of group B Streptococcus endogenous endophthalmitis (GBSEE) and to review the literature. DESIGN: Retrospective, noncomparative, interventional case series and literature review. PATIENTS: All patients with this condition treated at the Singapore National Eye Centre from 1994 through 2001. INTERVENTIONS: Core or complete vitrectomy and intravitreal and systemic antibiotics. METHODS: A review of the systemic and ocular characteristics and treatment. MAIN OUTCOME MEASURE: Visual outcome. RESULTS: Group B Streptococcus endogenous endophthalmitis developed in four patients after the onset of septic arthritis and in one patient with cervical epidural abscess after acupuncture, presenting as a diffuse endophthalmitis. Group B Streptococcus was isolated in the blood, vitreous, and joints. Despite the use of high-dose intravenous antibiotics within 72 hours of ocular presentation, intravitreal antibiotic injection, and vitrectomy (two eyes), all eyes lost light perception and became phthisical. A survey of the literature revealed that GBSEE is rare and that 17 cases have been reported since 1985. For purposes of analysis, four of these cases were excluded because of inadequate details and our five cases were included. Group B Streptococcus endogenous endophthalmitis was found to arise from hematogenous spread from cutaneous sites of infection (16.7%), pharyngitis (11.1%), and pneumonia (11.1%). Septic arthritis (38.9%) and endocarditis (33.3%) were concomitant sites of infection along with endophthalmitis. The septic arthritis typically involved multiple joints. Four patients (22.2%) had diabetes mellitus and three had other underlying predisposing illness. Although most patients received intravenous (83.3%) and intravitreal (55.6%) antibiotics and four eyes underwent therapeutic vitrectomy, useful vision was preserved in only four eyes. Two patients died of sepsis. CONCLUSIONS: Group B Streptococcus endogenous endophthalmitis is a devastating condition often associated with septic arthritis. The visual prognosis is poor, despite therapy.

Therapeutic strategy in delayed postoperative endophtalmitis: a report on 15 cases

PURPOSE: To report the treatment strategies and visual acuity outcomes of chronic postoperative endophthalmitis. MATERIAL: and methods: The authors reviewed the records of 15 patients presenting 3 or more weeks after cataract surgery with intraocular inflammation and treated at Bicêtre Hospital from 1992 to 1998. Group I included 6 consecutive patients treated with vitrectomy and intravitreal antibiotic injection (vancomycin and cefazolin). Group II included 9 consecutive patients treated with intravitreal antibiotic injection (vancomycin and ceftazidime) and irrigation of the capsular bag (vancomycin). The minimum follow-up period was 1 year. RESULTS: In group I, 2 patients had recurrent inflammation. In these patients, the capsular bag and the intraocular implant were removed. In 1 patient there was culture-proven Corynebacterium and in 1 patient a Staphylococcus epidermidis was found. Final visual acuity was 20/40 or better in 5 patients and 20/100 in 1 patient. Visual acuity improved in all cases. In group II no recurrence was seen in the 12-20 months of follow-up. In 2 patients there was proven Staphylococcus epidermidis and in one patient Propionibacterium acnes was found. Final visual acuity was 20/40 or more in 3 patients, 20/100 or more in 4 patients and less than 20/200 in 2 patients. Visual acuity improved in 8 cases. CONCLUSIONS: Intravitreal antibiotic injection with vitrectomy and intravitreal antibiotic injection with antibiotic irrigation of the capsular bag are both effective in the treatment of delayed chronic postoperative endophthalmitis; however, with the second approach, there is minimal surgical trauma and the intraocular implant is retained.     

Spectrum of signs,symptoms, and treatment in amphotericin B–resistant Trichosporon endophthalmitis: A series of ten cases of post–cataract surgery cluster endophthalmitis

Purpose:The aim of this study was to present the signs, symptoms, management, and outcome of a series of cases of cluster endophthalmitis caused by a multi-drug resistant fungus, Trichosporon.Methods:This was a retrospective, non-randomized, consecutive interventional case series. Ten cases of postoperative endophthalmitis operated by a surgeon on three consecutive operation theater (OT) days presented 3–5 months after their surgery. All cases were microbiologically confirmed. The pathogen was found to be resistant to most antifungals, including amphotericin B. The cases had a latent period of around 45 days. Management of endophthalmitis included intravitreal injections, anterior chamber (AC) lavage, Pars Plana vitrectomy (PPV), posterior capsulotomy, IOL, and capsular bag removal. Multiple intravitreal injections were required due to recurrence of infections after initial improvement with voriconazole injections.Results:Structural integrity was maintained and infection-free status was achieved in all the eyes. The presenting vision ranged from 6/60 to PL (perception of light). Seven out of 10 had improvement in their final vision over the presenting vision. Final outcome of four patients had vision of 6/24 or better, 4 patients had vision in the range of 2/60 to 6/36 and 2 patients had PL.Conclusion:Trichosporon can cause devasting infections even in the immunocompetent, especially in association with implants and catheters. Triazoles form the mainstay of treatment of Trichosporon infection due to the high susceptibility of the organism in vitro. A regimen including voriconazole and amphotericin B may prove to be the most effective. This is the first report of an outbreak of cluster endophthalmitis caused by Trichosporon.     

Assessment of a standard treatment protocol on visual outcome following presumed bacterial endophthalmitis

AIMS—The aim of this prospective study was, firstly, to judge the effect of early aggressive treatment with a standardised regimen of high dose broad spectrum intraocular and systemic antibiotics on visual outcome and, secondly, to assess the sensitivity of isolated organisms to the treatment regimen utilised.
METHODS—Thirty two consecutive patients presenting with presumed bacterial endophthalmitis were treated and completed follow up. In every case, intraocular sampling was undertaken and treatment with intraocular vancomycin, amikacin, and systemic ciprofloxacin was commenced immediately, followed by systemic steroids 1 day later.
RESULTS—In 69% of patients vision improved with 47% achieving a final visual acuity of 6/36 or better and 31% achieving 6/12 or better. Of the intraocular samples taken from post-surgical and post-traumatic cases, 10/27 (37%) and 3/5 (60%) were culture positive, respectively. All the bacteria isolated were sensitive to at least one of the three antibiotics used.
CONCLUSIONS—The study demonstrated that the combination of vancomycin, amikacin, and ciprofloxacin is adequate as a standard regimen for the treatment of most patients with suspected bacterial endophthalmitis. The prognosis for a good visual outcome, however, remains poor with 15/27 (55%) post-surgical and 2/5 (40%) post-traumatic cases achieving a final acuity of 6/60 or less.

Clinical profile,visual outcome and root cause analysis of post-operative cluster endophthalmitis due to Burkholderia cepacia complex

Purpose:To present varied clinical presentations, surveillance reports, and final visual outcomes of a rare outbreak of cluster endophthalmitis caused by gram-negative, opportunistic bacilli, Burkholderia cepacia complex (Bcc).Methods:Details of five patients who developed postoperative cluster endophthalmitis were collected. For each patient, an undiluted vitreous sample was collected during vitreous tap. Bacterial culture from the vitreous sample in each case had grown Bcc. Surveillance investigations for root cause analysis (RCA) were performed in the operating room (OR), admission, and day-care wards to localize the source.Results:Four patients had undergone phacoemulsification surgery, and one patient had undergone penetrating keratoplasty. Each patient received an initial dose of empiric intravitreal ceftazidime and vancomycin. The organism isolated in each case was sensitive to ceftazidime, cotrimoxazole, and meropenem and resistant to other antibiotics. Core vitrectomy was done after 48–60 hours in four patients along with intravitreal imipenem injection. One patient did not provide consent for core vitrectomy and subsequently developed phthisis bulbi. Three patients had subsequent recurrences. Two patients had a final BCVA of 20/60, two had BCVA better than 20/200, while one patient had no perception of light. None of the surveillance samples from the OR complex could isolate Burkholderia.Conclusion:Extensive OR surveillance should be done to identify the potential source of infection. However, the source may not be identifiable in few instances like in our case. Longer follow-up is recommended in cases of Bcc endophthalmitis due to the persistent nature of the infection.     

Successful treatment of postoperative fungal endophthalmitis using intravitreal and intracameral voriconazole

AIM: The aim of this study was to describe 3 cases of postoperative fungal endophthalmitis successfully treated with anterior chamber washout, pars plana vitrectomy, and intracameral and intravitreal voriconazole injection. RESULTS: Three (3) patients from a single retina center in India developed culture-proven fungal endophthalmitis after cataract surgery in 1 eye. All patients underwent anterior chamber washout, pars plana vitrectomy, and intracameral and intravitreal voriconazole injections intraoperatively. All cases demonstrated substantial improvement in vision and intraocular inflammation after surgery. CONCLUSIONS: The combination of anterior chamber washout, pars plana vitrectomy, and intracameral and intravitreal voriconazole injection is a viable therapeutic option in cases of fungal endophthalmitis.

Intravitreal dexamethasone in exogenous bacterial endophthalmitis: results of a prospective randomised study

AIM: To evaluate the efficacy of intravitreal dexamethasone co-administered with intravitreal antibiotics along with vitrectomy in the management of exogenous bacterial endophthalmitis. METHODS: In a prospective randomised clinical trial, 63 patients (63 eyes) with suspected bacterial endophthalmitis (postoperative and post-traumatic) were treated with vitrectomy and intravitreal antibiotics and randomised to intravitreal dexamethasone (IOAB with = 29 eyes) and no dexamethasone (IOAB without = 34 eyes). Inflammation score (IS) and visual acuity were measured by two masked observers before surgery, and at 1, 4, and 12 weeks after surgery in both the groups. RESULTS: There was significant reduction (p <0.0001) in IS at 1, 4, and 12 weeks after the surgery in the "IOAB with" group; there was temporary but significant increase (p <0.01) in IS at 1 week in the "IOAB without" group, before decline (p <0.001) of IS at 4 and 12 weeks. The magnitude and relative percentage change in IS between the two groups were found to be significant at 1 (p <0.0001), and 4 (p <0.01) weeks, and not at 12 weeks. The visual acuity at 12 weeks was comparable in both the IOAB with and IOAB without groups. CONCLUSION: Intravitreal dexamethasone helps in early reduction of inflammation in exogenous bacterial endophthalmitis, but has no independent influence on the visual outcome. In selected patients with endophthalmitis where oral corticosteroids cannot be given for medical reasons intravitreal corticosteroids could be beneficial; in other situations they could be complementary to oral corticosteroid therapy.

Clinical profile and outcome in Bacillus endophthalmitis

OBJECTIVE: To study the clinical presentation, microscopic and organismal culture correlation of vitreous, and species-specific outcome in Bacillus endophthalmitis DESIGN: Retrospective noncomparative case series. INTERVENTION: Thirty-one culture proven Bacillus endophthalmitis patients between January 1991 and February 1998 underwent vitrectomy and intravitreal antibiotic injection. Lensectomy was combined when considered essential, and on a few occasions intravitreal dexamethasone was added. The patients also received topical and systemic antibiotics. The undiluted vitreous biopsy was the source for microbiologic evaluation (microscopy and culture sensitivity). MAIN OUTCOME MEASURES: The duration of symptoms, the presenting visual acuity, and influence of intravitreal dexamethasone with intravitreal antibiotics were examined for any statistical correlation with the final visual acuity. RESULTS: Trauma was the major cause of infection. Vitreous biopsy microscopy demonstrated gram-positive bacillus in 28 of 31 cases, and polymicrobial infection was seen in 12 instances. All Bacillus species were sensitive to gentamicin, followed by vancomycin and ciprofloxacin. Clinical treatment within 7 days of symptoms, use of intravitreal vancomycin, and absence of polymicrobial infection were associated with better visual outcome. CONCLUSIONS: With appropriate treatment that essentially consists of vitrectomy and intravitreal antibiotics, patients with Bacillus endophthalmitis are likely to benefit in many instances. Gram-positive bacilli detected on vitreous microscopy should be empirically treated as Bacillus species unless otherwise proved.
