Management of scleral tears with concurrent intraocular foreign bodies and factors affecting outcomes.

AIM: To report the clinical settings and factors predicting outcomes in scleral tears with concurrent retained intraocular foreign bodies METHODS: All cases with scleral and corneoscleral wounds with retained intraocular foreign bodies (RIOFB) from January 2014 to January 2021 were retrospectively analysed. Favourable anatomic outcome was defined as presence of globe integrity, attached retina, absence of hypotony and active inflammation at last visit. Favourable functional outcome was defined as final visual acuity (VA) > 20/200. RESULTS: Total 139 eyes were included. Mean age was 30.66 ± 13.32 years (median 29 years, IQR 17). Penetrating trauma accounted for 87.1%, rupture for 5.8%, perforation for 7.2%. In 5.8% of the eyes the injury involved zone I extending till Zone II while in 66.9% it involved Zone II and in 27.3% in Zone III. Snellen visual acuity at presentation was logMAR 2.97 ± 1.01 and at last visit was logMAR 2.38 ± 1.45 (p < 0.0001). Time between presentation and repair was 13.93 ± 19.56 h (median 7.6 h, IQR 17.17). Favourable functional outcome was seen in 34.5% eyes and 2/3rd achieved favourable anatomic outcome. Absence of endophthalmitis (OR = 6.25, p = 0.003) and ability to remove the foreign body (OR = 7.05, p = 0.003) were associated with a favourable anatomic outcome. Better presenting Snellen visual acuity (OR = 2.77, p = 0.003), manifest scleral tear (OR = 3.36, p = 0.04), and absence of endophthalmitis (OR = 50, p = 0.0009) were associated with a favourable functional outcome. CONCLUSION: A third of the cases achieved favourable visual outcome while 2/3rd achieved favourable anatomic outcome. Absence of endophthalmitis is an important factor predicting both.

Pyogenic liver abscess complicated with endogenous endophthalmitis caused by Klebsiella pneumoniae: A case report and Literature Review.

OBJECTIVE: Pyogenic liver abscess (PLA) is a common surgical infectious disease caused by various pathogens. Klebsiella pneumoniae is a relatively recent cause, often affecting patients with low immunity. Endogenous endophthalmitis (EE), a rare and serious complication of PLA, may appear with eye symptoms before PLA. By reviewing a case of Klebsiella pneumoniae-induced PLA complicated with EE, we want to summarize the information about the characteristics, causes, and complications of PLA based on the literature review. METHODS: This case report describes a 37-year-old male who had fever high to 39°C for 10 days experienced blurred vision followed by nonlight perception vision. He reported a history of diabetes irregularly taking oral medications and insulin therapy. Imaging examination found a large low-density area in the right lobe of the liver with an unclear border and vague surrounding fat gap. The blood culture was not positive. The culture of the drainage fluid from the liver puncture showed Klebsiella pneumonia. Blood and liver puncture drainage fluid were sent for microbial high-throughput gene detection with next-generation sequencing technology (NGS), which confirmed the diagnosis of Klebsiella pneumoniae-induced PLA complicated with EE. RESULTS: The patient's surgical incision had healed well at discharge, and he could feel light at his left eye. But the patient was lost to follow-up since the third month after discharge. CONCLUSION: By reviewing this case and summarize the information about the characteristics, causes, and complications of PLA based on the literature review, we concluded that it is necessary to promptly perform liver puncture drainage and empirically use antibiotics for patients with PLA, especially those with poor glycemic control, to avoid serious complications such as EE.

Evaluation of Outcomes of Acute Cataract Surgery-Related Endophthalmitis Using a Novel Management Algorithm Based on Presenting Risk Factors.

PURPOSE: Develop treatment algorithm for acute endophthalmitis (AE) following cataract surgery. METHODS: Retrospective single-center, non-randomized interventional study involving patients with AE divided into cohorts according to our novel scoring system, the Acute Cataract surgery-related Endophthalmitis Severity (ACES) score. Total score ≥3 points indicated need for urgent pars plana vitrectomy (PPV; within 24 hours), whereas <3 points indicated urgent PPV was unnecessary. Patients were retrospectively evaluated for visual outcomes based on whether their clinical course followed with or deviated from ACES score recommendations. Main outcome was best-corrected visual acuity (BCVA) at 6-month or longer after treatment. RESULTS: Total of 150 patients were analyzed. Patients whose clinical course followed the ACES score recommendation for immediate surgery had significantly (P < 0.01) better final BCVA (median = 0.18 logMAR, 20/30 Snellen) compared to those that deviated (median = 0.70 logMAR, 20/100 Snellen). For those where the ACES score deemed urgent PPV was unnecessary, no significant (P = 0.19) difference was observed between patients that followed with (median = 0.18 logMAR, 20/30 Snellen) and those that deviated from (median = 0.10 logMAR, 20/25 Snellen) recommendation. CONCLUSIONS: The ACES score may potentially provide critical and updated management guidance at presentation for when to recommend urgent PPV for patients suffering from post-cataract surgery AE.

Acute postoperative endophthalmitis after cataract operation: result of early vitrectomy within 24 hours of presentation.

OBJECTIVES: To evaluate result of early pars plana vitrectomy (PPV) within 24 hours of presentation for acute postoperative endophthalmitis after cataract operation, and to determine factors that predict visual outcome. METHODS: Consecutive patients who developed acute postoperative endophthalmitis within 6 weeks after cataract operation were reviewed. Patients were divided into two groups for analysis: (1) those receiving PPV within 24 hours of presentation (early PPV group), and (2) those receiving initial intravitreal antibiotics only without PPV within 24 hours of presentation (IVA group). RESULTS: Out of 41,411 cataract operations, 22 eyes developed acute postoperative endophthalmitis. Presenting VA was hand-movement or worse in 72.7%. The most common organisms were Staphylococcus (40.9%), Streptococcus (13.6%) and Enterococcus (13.6%). 22.7% of eyes had good final VA ≥ 20/30 and 27.3% had poor final VA < 20/400. Early PPV group had significantly lower rate of requiring additional treatments to control infection (25% versus 80%, P = 0.030), higher rate of retinal detachment (25% versus 0%, P = 0.221) and similar final logMAR VA (1.08 ± 1.08 versus 0.80 ± 0.80, P = 0.489) compared to IVA. Multivariate linear regression analysis showed that worse final VA was significantly associated with Streptococcus (ß = 1.92, P = 0.007) and retinal detachment (ß = 1.72, P = 0.005) but not with early PPV (P = 0.225). CONCLUSION: Early PPV was superior to initial intravitreal antibiotics alone as it required fewer additional treatments to control infection. Visual outcome was similar between early PPV and initial intravitreal antibiotics alone despite high number of poor presenting VA of light-perception in early PPV group. Streptococcal infection and retinal detachment were major poor prognostic factors for vision.

Case Report: Microsporidial Endophthalmitis after Penetrating Eye Trauma.

SIGNIFICANCE: In the recent past, there are increasing publications on microsporidia affecting the cornea in Asian population. However, microsporidia-causing endophthalmitis has been rarely reported. This report intends to draw the attention of eye care professionals to consider microsporidia as a differential diagnosis in cases of keratitis or endophthalmitis after ocular trauma. PURPOSE: The purpose of this study was to report a case of microsporidial endophthalmitis after corneal tear in an otherwise healthy patient. CASE REPORT: A 62-year-old healthy gentleman sustained injury to the left eye cornea with the tip of a soiled and wet screw driver. Two days after the corneal tear suturing, he complained of pain. On examination, circumcorneal congestion with hypopyon of 2 mm in height was present. Vitreous tap and intravitreal antibiotics were injected. Vitreous tap showed microsporidia. Pars plana vitrectomy was performed. His vision improved to 6/12. CONCLUSIONS: Microsporidia are an emerging cause of stromal keratitis. In the recent past, there has been an increase in microsporidial keratitis in both immunocompetent and immunocompromised individuals. History of trauma especially in rainy season and exposure to soil are reported risk factors. This is a case report on microsporidia-causing endophthalmitis after corneal tear repair. Ophthalmologists and optometrists should be aware of the possibility of microsporidia as a potential pathogen causing stromal keratitis or endophthalmitis in a setting of ocular trauma. Early treatment can result in good visual recovery.

[Ophthalmopathologic Aspects of Endophthalmitis]. / Endophthalmitis aus ophthalmopathologischer Sicht.

Endophthalmitis is one of the most severe ophthalmic emergencies. Most patients experience a permanent decrease in visual acuity after the event, but the eye can be preserved in most cases. However, when the eye is enucleated after endophthalmitis, ophthalmopathologic investigation of the globe with respect to the clinical history can provide valuable information regarding the ultimately frustrating course of the disease that can be helpful for the treatment of future patients. Often, valuable aspects also emerge with regard to the therapeutic approach. For example, in therapy-resistant fungal endophthalmitis the necessity of penetrating keratoplasty with a large graft diameter and possibly even removal of the lens including the capsular bag should be stressed. In the following, five enucleated eyes with a different spectrum of endophthalmitis, as well as different potential pathways of exogenous and endogenous endophthalmitis, are illustrated clinically and ophthalmopathologically. In summary, endophthalmitis requires urgent intervention; however, various differential diagnoses must be excluded. Histopathologic examination of enucleated eyes is helpful for understanding the course of the disease and may also have forensic significance.

Treatment of long-term endophthalmitis developing after intraocular lens implantation in children: a retrospective study.

BACKGROUND: To discussed the risk factor and the management of vitrectomy for long-term endophthalmitis developing after intraocular lens (IOL) implantation in children. METHODS: We retrospectively investigated the clinical characteristics and surgical outcomes of long-term endophthalmitis developing after IOL implantation in children. RESULTS: Four eyes of four children were included in the study. The mean time to endophthalmitis development after IOL implantation was 3.0 ± 0.8 years. The corneal or scleral sutures may have been caused the infection. All 4 patients underwent vitrectomy and received intravitreal antibiotics with or without IOL removal. At the last follow-up, the outcomes were satisfactory; the fundus was clear, the retina remained attached, the visual acuity improved, and there were no severe complications. CONCLUSIONS: The use of scleral sutures and the exposure of conceal sutures may induce the onset of long-term endophthalmitis after IOL implantation. Complete vitrectomy and appropriate use of antibiotics are effective in the treatment of long-term endophthalmitis developing after IOL implantation in children.

[Chinese expert consensus on the diagnosis and management of infectious endophthalmitis after ophthalmic surgery (2022)].

Infectious endophthalmitis after ophthalmic surgery refers to postoperative endophthalmitis associated with pathogen infection. The incidence of infectious endophthalmitis after ophthalmic surgery has been reduced, but there are still many controversial issues in its diagnosis, treatment and prevention. The Chinese Vitreo-Retina Society of Chinese Medical Association, together with domestic experts in cataract, trauma and glaucoma, has synthesized all the current research evidences available at home and abroad and reached consensus opinions after careful discussion, in order to provide reference for preventing and managing infectious endophthalmitis after ophthalmic surgery safely and effectively, and thus to improve its cure rate and patients' visual function.

CLINICAL PRESENTATIONS, MICROBIOLOGY, AND FACTORS AFFECTING MANAGEMENT OUTCOMES IN LENS ABSCESS WITH CONCURRENT ENDOPHTHALMITIS.

PURPOSE: To describe the clinical presentations, microbiology, and factors affecting management outcomes in lens abscess with concurrent endophthalmitis. MATERIALS: A retrospective, consecutive, noncomparative series including cases of endophthalmitis with concurrent lens abscess from January 2017 to May 2021. RESULTS: This study included 102 eyes, predominantly male (71.6%). All cases were posttrauma. The mean age noted was 30.47 ± 19.51 years. Presenting vision was logMAR 3.02 ± 0.74 (median 3.5, Snellen 20/63245). A favorable anatomical outcome was seen in 63 eyes (61.8%), while a final favorable functional outcome was seen in 51 eyes (50%). The mean follow-up duration was 10.04 ± 10.87 months (median 4.5). Final vision was logMAR 2.13 ± 1.32 (median 2.7, Snellen 20/10023) (P < 0.0001). The mean follow-up duration was 10.04 ± 10.87 months (median 4.5). Increasing age (OR 1.04, P = 0.02), female sex (OR 7.91, P = 0.007), initial intervention of vitrectomy instead of limited vitreous biopsy (OR 11.72, P = 0.009), and a negative vitreous culture (OR 14.28, P = 0.0004) predicted a favorable anatomical outcome. Absence of a corneal infiltrate (OR 11.11, P = 0.003) and initial intervention of vitrectomy instead of a limited vitreous biopsy (OR 21.96, P < 0.0001) predicted a favorable functional outcome. Culture positivity was seen in 56.9% of the cases. Gram-positive organisms were predominant (n = 41) followed by Gram-negative organisms (n = 12) and fungi (n = 10). CONCLUSION: Lens abscess can present concurrently with traumatic endophthalmitis. Management should involve the complete removal of the crystalline lens along with a pars plana vitrectomy for optimal outcomes.

Retinal Vasculitis and Posterior Pole Preretinal Exudates in Exogenous Bacterial Endophthalmitis: Management and Visual Outcomes.

PURPOSE: To investigate the clinical settings and features, management, and visual outcomes of exogenous bacterial endophthalmitis with retinal vasculitis and posterior pole preretinal exudates. METHODS: Retrospectively reviewed records for 40 eyes of 40 patients. RESULTS: Retinal vasculitis was identified with focal type in eight eyes and diffuse type in 32 eyes. Posterior pole preretinal exudates were identified with discrete type in 23 eyes and condensed type in 17 eyes. Final VA was 20/200 or better in 23 of 40 eyes (57.5%). Multivariate linear regression revealed that condensed posterior pole preretinal exudates (P =.005) and ocular hypertension (P =.012) were the significant independent factors for poor visual outcomes. CONCLUSIONS: Condensed posterior pole preretinal exudates and ocular hypertension are critical prognostic factors for poor visual outcomes.

CLOSTRIDIAL ENDOPHTHALMITIS: CLINICAL PRESENTATIONS, MANAGEMENT OUTCOMES, AND REVIEW OF LITERATURE.

PURPOSE: To describe the clinical presentations, diagnosis and management outcomes of clostridial endophthalmitis, and a review of the previous literature. DESIGN: Retrospective, interventional case series from January 2005 to March 2018 and a literature review. METHODS: The study included seven eyes of seven patients with culture-proven Clostridium sp. endophthalmitis. Identification of Clostridium sp. was confirmed by the VITEK 2 system using the ANC card. When VITEK failed to identify the organism, MALDI-TOF was used. Data regarding demography, clinical presentations, interventions received, and final visual and anatomical outcomes were noted. RESULTSTHE: mean age of the patients was 28.28 ± 22.35 years (median 21 years). By the etiology of infection, 5 (75%) eyes were post-open-globe injury, 1 (12.5%) was post-trabeculectomy, and 1 (12.5%) was postintravitreal injection. The mean follow-up was 9.71 ± 12.03 months, median 6 months. Two samples were positive for Clostridium perfringens, one each for C. subterminale, C. difficile, and C. tertium, and two were unidentified clostridial species. Favorable anatomical outcome was seen in 3/7 eyes (42.85%). Favorable functional outcome was seen in 2/7 eyes (28.57%). These were comparable with the outcomes of the pooled pre-existing literature. There was a trend toward better functional and anatomical outcomes and lesser evisceration/enucleation rates with vitrectomy instead of a vitreous tap, although not statistically significant. All cases showed susceptibility to empirically used intravitreal antibiotic vancomycin. CONCLUSION: Commonest setting of clostridial endophthalmitis is post-open-globe injury. Despite treatment with appropriate antibiotics, the visual and anatomical outcome is unsatisfactory because of high organism virulence. Early vitrectomy may allow for globe salvage and potential vision.

Endogenous Endophthalmitis: A 21-Year Review of Cases at a Tertiary Eye Care Centre.

PURPOSE: Endogenous endophthalmitis is rare and associated with significant morbidity and mortality. The primary objective was to identify causative organisms. Secondary objectives included the determination of systemic risk factors and visual prognostic factors. DESIGN: Retrospective review. METHODS: 78 eyes from 62 subjects over a 21-year period from 1999 to 2020 in Auckland, New Zealand. Parameters assessed included pathologic microbial organism, clinical presentation, treatment, complications, prognostic factors, and visual outcomes. METHODS: Information was collected on microbiology, treatment, visual outcomes, and complications. RESULTS: Median age was 61.6 years and 32 subjects (51.6%) were male. Diabetes was the most common risk factor seen in 24 (38.7%) subjects. 17 subjects (27.4%) presented directly to ophthalmology and 17.4% had an initial misdiagnosis. 49 subjects (79.0%) presented with reduced vision and only 27 (43.5%) presented with pain. Hypopyon was present in 13 eyes (16.7%). Gram-positive bacteria were the most common causative organism seen in 40 (51.3%) eyes, followed by yeast and fungi in 21 (26.9%) eyes, then gram-negative bacteria seen in 17 (21.8%) eyes. Median final BCVA was 6/18. Severe vision loss occurred in 33 (42.3%) eyes and 7 (9.0%) eyes required evisceration or enucleation. Presenting visual acuity was a significant predictor of visual outcome. CONCLUSION: Endogenous endophthalmitis occurred at 1.9 cases per million per year. Ophthalmologists require a high index of suspicion for underlying systemic infection in any subject presenting with ocular inflammation, and need to be aware that endogenous endophthalmitis may present without pain and frequently without hypopyon.

Clinical Presentations and Management Outcomes of Culture-Proven Mixed Bacterial and Fungal Endophthalmitis.

OBJECTIVE: To report the clinical features and management outcomes of mixed fungal and bacterial endophthalmitis. METHODS: Retrospective, consecutive non-comparative case series. Fifteen eyes of 15 patients were included from January 2009 to December 2019 with culture proven mixed fungal and bacterial endophthalmitis. Demography, clinical presentations, interventions received, and final visual and anatomical outcomes were noted. A favorable anatomic outcome was defined as preservation of the globe, absence of hypotony, attached retina, and absence of active inflammation at the last visit. RESULTS: The mean age of patients in this series was 34.2 ± 19.6 years (range: 5-61 years). Male preponderance was found in 14 (93.3%). Eight (53.3%) eyes had open globe injury, 5(33.3%) had postoperative endophthalmitis and one (6.6%) each with endogenous endophthalmitis and post-keratitis. Pars plana vitrectomy was done in eight (53.3%) eyes whereas vitreous tap alone was done in seven (46.7%) eyes. Gram positive cocci (n = 11, 73.3%) were the commonest bacterial isolates (n = 7, 46.6%). Staphylococcus aureus (n = 3, 20%) was the most common bacterial isolate. The commonest fungi were filamentous hyaline fungi (n = 5, 33.3%). An unfavorable visual outcome (VA<20/400) was seen in all the eyes. The mean duration of follow-up was 13 ± 18.3 months. Globe salvage was possible only in five (33.3%) eyes. The bacterial isolates were highly sensitive to all of the tested antibiotics. CONCLUSION: Mixed fungal and bacterial endophthalmitis occur commonly in a setting of open-globe trauma. The presence of fungus concurrently leads to a very poor management outcome even if the bacterial isolate sensitivity is good.

CLINICAL CHARACTERISTICS AND VISUAL OUTCOMES IN ENDOPHTHALMITIS AFTER KERATOPROSTHESIS IMPLANTATION.

PURPOSE: To describe the presentation, microbiology, management, and prognosis of eyes with endophthalmitis after Boston keratoprosthesis implantation. METHODS: Retrospective case series with history, diagnostics, management, and outcomes data in endophthalmitis after keratoprosthesis implantation presenting to a tertiary center between 2009 and 2020. RESULTS: Of 137 keratoprosthesis-implanted eyes, 7 eyes of 7 patients (5%) developed endophthalmitis. On presentation, 6 (86%) reported decreased visual acuity, and only 1 (14%) reported pain. Peripheral corneal ulcers were present in 2 eyes (29%). Seidel testing was negative in all cases. Six eyes (86%) had retroprosthetic membranes. One (14%) underwent initial pars plana vitrectomy with mechanical vitreous biopsy, whereas 6 (86%) received a needle vitreous tap-half of which were dry. Organisms were isolated after vitreous tap in two eyes: Streptococcus intermedius and Mycobacterium abscessus. The mean visual acuity preendophthalmitis, at presentation, and at 6 months were 20/267, 20/5,944, and 20/734, respectively. The visual acuity improved 9.08 ± 11.78 Early Treatment Diabetic Retinopathy Study lines from presentation to 6 months. Six-month visual acuity was correlated with preendophthalmitis visual acuity (r = 0.92, P = 0.003) but not presenting visual acuity (P = 0.838). CONCLUSION: Visual acuity at 6 months is correlated with preendophthalmitis visual acuity, not presenting visual acuity. Endophthalmitis should be considered in the differential diagnosis of painless intraocular inflammation any time after keratoprosthesis implantation, even if Seidel negative.

Fungal Endophthalmitis: Analysis of 730 Consecutive Eyes from 7 Tertiary Eye Care Centers in India.

PURPOSE: To evaluate the clinical and microbiological features of a large cohort with culture-confirmed fungal endophthalmitis across India. DESIGN: Cross-sectional, hospital-based, retrospective medical record review. PARTICIPANTS: Seven large tertiary eye care centers from different regions of India. METHODS: Patient data were pooled from electronic or physical medical records of each participating center. Fellowship-trained vitreoretinal specialists clinically managed all patients, and in-house microbiology laboratories performed all microbiological workups. The clinical and microbiological procedures were broadly uniform across all participating centers. The essential treatment consisted of vitreous surgery as well as intravitreal and systemic therapies with antifungal agents. MAIN OUTCOME MEASURES: Clinical outcome of the causative event and causative fungus. RESULTS: In the period from 2005 to 2020, 7 centers treated 3830 cases of culture-proven endophthalmitis, and of these, 19.1% (n = 730) were cases of culture-confirmed fungal endophthalmitis. It included 46.9% cases of postoperative (87.4% postcataract surgery), 35.6% of traumatic, and 17.5% of endogenous endophthalmitis. The fungi included 39.0% of Aspergillus (high prevalence in central, east, and south zones), 15.1% of Candida (high prevalence in west zone), and 15.9% of Fusarium (high prevalence in north and west zones). The time to symptom development was between 1 week and 4 weeks in more than one third of the patients, except in patients with traumatic endophthalmitis. Less than half of the patients had hypopyon on presentation. The presenting visual acuity (PVA) in most patients was <20/400. Nearly all patients needed vitrectomy and an average of 2 intravitreal injections of antifungal agents. At least 10% of eyes needed therapeutic keratoplasty, and up to 7% of eyes were eviscerated. After treatment, the final (best corrected) visual acuity (FVA) was >20/400 in 30.5% (n = 222) of eyes and >20/40 in 7.9% (n = 58) of eyes, and 12% (n = 88) of eyes lost light perception. A post hoc analysis showed the male sex to be significantly more associated with traumatic endophthalmitis than with postoperative (P < 0.0001) and endogenous (P = 0.001) endophthalmitis, more isolation of Candida species in patients with endogenous endophthalmitis than in those with postoperative (P = 0.004) and traumatic (P < 0.0001) endophthalmitis, better PVA in eyes with Candida species infection (P < 0.0001), and poorer FVA in eyes with Aspergillus species infection. CONCLUSIONS: Fungal endophthalmitis is not uncommon in India. The inclusion of antifungal agents with antibiotics as the first empirical intravitreal therapy before microbiological confirmation should be considered when a fungal infection is suspected.

Analysis of retinal detachment resulted from post-operative endophthalmitis treated with 23G pars Plana Vitrectomy.

BACKGROUND: To evaluate the rate, risk factors, functional outcome and prognosis in eyes with retinal detachment after post-operative endophthalmitis treated with 23G Pars Plana Vitrectomy. METHODS: Electronic patient files from 2009 until 2018 were screened for the presence of an endophthalmitis. Included were 116 eyes of 116 patients. This population was evaluated for the rate of retinal detachment after 23G Pars Plana Vitrectomy for endophthalmitis following cataract surgery or intravitreal injection. The main outcome measures were retinal detachment and visual acuity. RESULTS: The reasons for endophthalmitis were previous cataract surgery in 78 patients and following intravitreal injection in 38 patients. The first clinical evidence of endophthalmitis was present in median 5 days after the triggering intervention. Twenty-five eyes (21.55%) developed a retinal detachment an average of 25 days after endophthalmitis. RD is significantly associated with preoperative visual acuity (p = 0.001). CONCLUSIONS: We emphasize the prognostic role of preoperative visual acuity in RD development of the endophthalmitis treated with 23G Pars Plana Vitrectomy.

Treatment outcomes of acute poptoperative infectious endophthalmitis.

BACKGROUND: Acute postoperative endophthalmitis is one of the most severe complications of modern ophthalmic procedures including cataract surgeries, vitrectomy and intravitreal injection (IVI). We evaluated the treatment outcomes of acute postoperative infectious endophthalmitis. METHODS: In this retrospective study, we collected data from 82 patients with acute infectious endophthalmitis within 6 weeks after intraocular surgeries, including cataract surgeries, vitreoretinal surgeries, and IVI, from January 2010 to December 2019. We analyzed the pre-treatment, treatment-related and post-treatment factors that affected visual outcomes. RESULTS: The mean age was 67.65 ± 9.52 years, the proportion of male patients was 56.1%. The mean baseline vision was 1.92 (Snellen Equivalent SE], counting finger [CF]) ± 0.54 logarithm of the minimum angle of resolution (log MAR) and the mean final vision was 0.71 (SE, 39/200) ± 0.80 logMAR. Visual improvement was significant (P < 0.001). The pre-treatment factors affecting final visual outcomes were diabetes, hemodialysis, baseline vision, signs of vitreous opacity, and different surgeries before endophthalmitis; the treatment-related factors affecting visual outcomes were the choice factors between IVI of antibiotics alone and vitrectomy combined with IVI of antibiotics, and the injection numbers of antibiotics; post-treatment factors affecting visual outcomes were complications such as retinal detachment (RD), glaucoma and macular pucker. Furthermore, prior cataract surgery was associated with a better mean final vision of 0.57 (SE, 54/200) ± 0.67 logMAR while prior vitrectomy resulted in the worst mean final vision of 1.38 (SE, 21/500) ± 0.75 logMAR. CONCLUSIONS: The important factors that affected the final visual prognosis, included diabetes, hemodialysis, baseline vision, severity of vitritis, treatment strategies and complications. The treatment outcomes revealed better final vision in prior cataract surgery than vitrectomy.
