[PMID: 38489503 DOI: 10.1080/09273948.2024.2322026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 02/12/2024] [Accepted: 02/17/2024] [Indexed: 03/17/2024]
Abstract
PURPOSE We aimed to compare the visual outcomes after pars plana vitrectomy (PPV) versus tap and inject (T&I) in fungal endophthalmitis (FE) reported in the literature and to compare the findings from the literature with data from a reference centre. METHODS We performed a systematic review and meta-analysis of studies reporting the use of PPV versus T&I in FE. We also performed a retrospective review of the clinical records of patients with endophthalmitis from a reference centre in Colombia. RESULTS We included 13 studies with 334 eyes; 53.59% received PPV and 46.4% received T&I. The overall relative risk of improving ≥ 2 lines in PPV versus T&I was 0.98 (95% confidence interval [CI] 0.80-1.22; p = 0.88) with a mean difference of final visual acuity of 0.26 (95% CI 0.12-0.63; p = 0.18). There were no significant differences in subgroup analysis. Data from the reference centre included 32 endophthalmitis cases, 15.6% of which had a fungal aetiology (80% received PPV and 20% T&I). There were no significant differences in the subgroup analysis. CONCLUSIONS Based on the findings from the literature and the reference centre, T&I is noninferior to PPV. This is the first meta-analysis in the literature evaluating these effects in FE. It is necessary to execute new prospective randomised controlled studies in patients with endophthalmitis.

Abstract
PURPOSE To report a case of endogenous endophthalmitis caused by the dematiaceous fungus Cladophialophora devriesii. METHODS Observational case report and literature review. CASE PRESENTATION A 73-year-old female with a history of chronic obstructive pulmonary disease presented with a red and painful left eye. Examination revealed anterior segment inflammation and vitritis, indicative of endophthalmitis. She underwent core vitrectomy and intravitreal injection of vancomycin and amphotericin B. The vitreous sample showed inflammatory cells and fungal hyphae, and systemic amphotericin B and itraconazole were commenced for fungal endophthalmitis. Targeted amplification of the sample for bacterial DNA (V2-V3 region of 16 S rDNA) was negative, but fungal DNA targets (ITS1 and ITS2) were present, and their sequences were consistent with Cladophialophora devriesii. Phenotypic characterisation and sequencing of ITS1 and ITS2, carried out on cultured fungus from the sample, also revealed Cladophialophora devriesii. She received repeated intravitreal injections of voriconazole, and based on the antifungal susceptibility results, her systemic medication was changed to posaconazole. After 12 months, the eye showed no signs of inflammation, and posaconazole therapy was discontinued. After 3 months without antifungal medication, the inflammation recurred, and she was restarted on antifungal therapy for an additional 20 months. Another recurrence occurred 3 months after discontinuation of treatment, and a repeat vitreous sample confirmed the presence of Cladophialophora devriesii. She was started on isavuconazole, but developed seclusio pupillae and painful secondary glaucoma. Due to the duration and severity of the infection, the eye was enucleated. Histopathology revealed persistent fungal elements at the ciliary processes and the posterior lens surface. CONCLUSIONS This second reported case of endogenous endophthalmitis caused by Cladophialophora devriesii illustrates the role of vitreous sampling and molecular methods in diagnosis and treatment of fungal endophthalmitis. Despite early diagnosis and prolonged local and systemic antifungal therapy, it was not possible to achieve long-term control of the fungal infection.

Abstract
AIMS The aims of this study are to investigate the etiology, microbiological spectrum, and risk factors associated with visual outcomes of fungal endophthalmitis (FE) in a tertiary eye specialty hospital in Shanghai, China. METHODS This was a retrospective, single-center case series. The clinical characteristics, etiology, microbiological spectrum, and management, as well as the visual outcomes, were analyzed. Logistic regression was used to analyze the factors related to visual outcomes. RESULTS This study involved 102 eyes of 92 patients with FE, including 63 males (66.3%). The mean age was 44.4 ± 19.8 years. The most common etiology of FE was trauma (56.5%). The predominant fungal species isolated were Aspergillus spp. (31/93, 33.3%). Pars plana vitrectomy (PPV) and intravitreal antifungal agents was performed initially in 86 (84.3%) and 83 (81.4%) eyes, respectively. Only 35 (34.3%) eyes achieved final best corrected visual acuity (BCVA) of 20/400 or better. Ten (9.8%) eyes had a final BCVA of light perception or worse, and five (4.9%) had to be enucleated. The factors determining better visual outcomes included initial visual acuity better than finger-counting (FC) (odds ratio (OR) 5.811, p = 0.036), the absence of corneal infiltrate (OR 10.131, p = 0.002), and Candida species infection (OR 6.325, p = 0.011). CONCLUSIONS Early diagnosis of FE and a timely vitrectomy, combined with an intravitreal injection of an antifungal drug, can mitigate the devastating results of intraocular fungal infection. Not being infected by Aspergillus spp., an initial BCVA that was no worse than FC, and the absence of corneal involvement were related to better visual prognosis.

Abstract
Endophthalmitis refers to inflammation involving internal ocular structures, including the anterior and posterior eye segments, associated with infectious agents, most commonly bacteria and fungi. This review focuses on endophthalmitis caused by fungi. Medical and surgical management are the two main treatment modalities for fungal endophthalmitis, with medical management utilizing systemic or intravitreal antifungals. The use of systemic or intravitreal corticosteroids as an adjuvant treatment to dampen the severity of inflammation is controversial. Based on the pathobiology of fungal endophthalmitis as well as the mechanism of action of corticosteroids, it was hypothesized that corticosteroids affected the immune response against fungal infection. In vitro studies mostly carried out during the 1980s showed that dexamethasone plays a role in the suppression of phagocytosis of yeasts and demonstrated the facilitation of yeast proliferation by dexamethasone. In vivo studies analysis was compromised entirely of retrospective studies describing steroid use in fungal endophthalmitis, with the outcomes of the patients in these studies varying greatly and often being anecdotally noted, thus difficult to discern any definitive results. Given the limited clinical data and the heterogeneity of the existing studies, additional experimentation human studies with clinical trials or observations over more extended periods analyzing the effect of systemic and intravitreal corticosteroids in fungal endophthalmitis are needed before definitive conclusions can be drawn.

Abstract
Infectious endophthalmitis is a severe intraocular infection caused by bacteria, or less commonly by fungi. It can occur after penetrating eye procedures, trauma, or the spread of infection from contiguous structures or via emboli from distant organs. Because of the time-critical nature of the treatment, endophthalmitis is treated with the clinical diagnosis and modified by the microbiological report of the intraocular contents. The current strategy for managing endophthalmitis relies on pre-clinical literature, case series, and one large multi-center randomized clinical trial on post-cataract surgery endophthalmitis. Culture-susceptibility of the microorganisms from undiluted vitreous guides the definitive treatment in non-responsive cases. Strategies to reduce the incidence of endophthalmitis after penetrating eye procedures have been developed concurrently with refined means of treatment. Despite these advances, outcomes remain poor for many patients. Although consensus articles have been published on managing endophthalmitis, treatment patterns vary, and controversies remain. These include (1) the use of newer methods for early and precise microbiological diagnosis; (2) the choice of intravitreal antibiotics; (3) the need for systemic therapy; (4) early and complete vitrectomy. Here, we review the current consensus and address controversies in diagnosing and managing endophthalmitis. This review is intended to familiarize physicians and ophthalmologists with different aspects of endophthalmitis management to make informed decisions.

Abstract
We describe a case of exogenous cryptococcal endophthalmitis without central nervous system (CNS) involvement or systemic infection in an immunocompetent patient. An 82-year-old male with hypertension, hyperlipidemia, type 2 diabetes mellitus, and primary open-angle glaucoma with a history of left eye trabeculectomy presented with 3 months of worsening left eye pain and redness. Vitreous cultures resulted as Cryptococcus, prompting treatment with intravitreal amphotericin and further investigation. Systemic workup was unrevealing for an endogenous source, CNS involvement, or immunocompromising conditions. He was treated with an aggressive regimen of systemic antifungals, leading to subjective improvements in clinical exam and in vision.

Abstract
Purpose: To report a case of Aspergillus terreus endophthalmitis associated with systemic immunosuppression and an intraocular steroid implant in a patient with sarcoidosis. Methods: A case report was evaluated and a literature review performed. Results: A patient with a history of pulmonary and ocular sarcoidosis presented with new-onset uveitis and was treated for presumed sarcoid flare with oral prednisone and an intravitreal dexamethasone implant before developing worsening vision. She was ultimately diagnosed with A terreus endophthalmitis. Despite both systemic and local antifungals, the visual acuity at the most recent follow-up was no light perception without pain or active inflammation. No definitive source of the fungal disease had been identified. Conclusions: Endophthalmitis resulting from A terreus is associated with poor outcomes. Given the ability of fungal endophthalmitis to mimic other causes of uveitis, one must maintain a high suspicion in patients with any degree of immunosuppression.

Abstract
This report describes a rare case of a fungal iris granulomatous lesion in a 67-year-old female who underwent cataract surgery in the left eye and, one month later, developed culture-positive postoperative Aspergillus endophthalmitis. On initial presentation in the emergency room, slit-lamp examination of the left eye revealed subconjunctival hemorrhage, 360-degree subconjunctival hemorrhage, mild corneal edema with Descemet's folds, a deep anterior chamber with a fibrinous reaction causing pupillary membrane formation, and an in situ intraocular lens with no view of the fundus. A bright-scan (B-scan) ultrasound revealed mild vitreous opacities with a vitreal membrane, shallow choroidal detachment, and no significant retinal and choroid layer thickening. The patient was admitted into the anterior segment division for anterior chamber (AC) tap culture and AC washout for suspected retained cortical matter removal, intracameral antibiotics (vancomycin and ceftazidime), and IOL explantation in the left eye. The initial aqueous tap culture had no growth. Nine days later, repeat aqueous tap and pupillary membrane cultures were positive for Aspergillus spp. Intravitreal voriconazole was administered along with topical natamycin and amphotericin B eye drops. There was a resolution of the clinical picture, and three weeks later a rebound occurred, for which AC washout, pars plana vitrectomy (PPV), capsulectomy, and intravitreal vancomycin, ceftazidime, and voriconazole were given. A week later, the patient developed a fungal granuloma behind the iris, which was successfully managed with an AC washout, removal of the granuloma, and repeated intravitreal and intracameral voriconazole administration. The best-corrected visual acuity (BCVA) during the last visit was 20/80 in the affected eye, with a plan for a secondary IOL implant. Endophthalmitis is a rare but serious intraocular infection, with fungal endophthalmitis having a lower prevalence than bacterial endophthalmitis, which explains the lack of well-established guidelines for diagnosing and managing exogenous fungal endophthalmitis. This case highlights the rare presentation of post-cataract Aspergillus endophthalmitis with a fungal iris granuloma and demonstrates how the chronicity of this infection, along with surgical manipulation, may accelerate the seeding of these organisms into the anterior chamber structures.

Abstract
INTRODUCTION We describe the case of a postoperative fungal endophthalmitis caused by Wickerhamomyces anomalus, an opportunistic yeast common in nature but rare as a causative agent in ocular infections. This would be the second reported case of W. anomalus endophthalmitis. CASE REPORT A patient came to our hospital with a dense hemovitreous caused by an inadvertent ocular perforation and retinal detachment during a cataract surgery. In the days following the first vitreoretinal surgery a chronic postoperative endophthalmitis was evidenced. Only after several surgeries as well as intravitreal antibiotics and sample takings, Wickerhamomyces was detected. The treatment with oral voriconazole and an intraocular lens extraction controlled the infection. DISCUSSION Wickerhamomyces anomalus, despite not being particularly aggressive in our case, was resistant to various consequent vitreoretinal surgeries. The unresponsiveness to treatment led us to contemplate the fungal etiology, and fortunately the cultures were positive for this yeast. In conjunction to antifungal therapy, it is possible that the IOL explantation played an important role in the treatment. CONCLUSION A high index of suspicion must be held in cases of fungal endophthalmitis. Both IOL explantation and oral antifungal therapy are useful treatment options in cases of W. anomalus endophthalmitis.

Abstract
Ocular fungal infections annually affect more than one million individuals worldwide. The management of these infections is problematic, mainly due to the limited availability of effective antifungal agents. Thus, ocular infections are increasingly recognized as important causes of morbidity and blindness, especially keratitis and endophthalmitis. Thus, this review aims to demonstrate the importance of fungal eye infections through the description of the main related aspects, with emphasis on the treatment of these infections. For this purpose, a search for scientific articles was conducted in databases, such as Medline, published from 2000 onwards, addressing important aspects involving fungal eye infections. In addition, this work highlighted the limited therapeutic arsenal available and the severity associated with these infections. Thus, highlighting the importance of constantly updating knowledge about these pathologies, as it contributes to agility in choosing the available and most appropriate therapeutic alternatives, aiming at positive and minimally harmful results for that particular patient.

Abstract
Importance Fungal endophthalmitis caused by contaminated medical products is extremely rare; it follows an intractable clinical course with a poor visual prognosis. Objective To report the epidemiologic and clinical features and treatment outcomes of a nationwide fungal endophthalmitis outbreak after cataract surgery as a result of contaminated viscoelastic agents in South Korea. Design, Setting, and Participants This was a retrospective case series analysis of clinical data from multiple institutions in South Korea conducted from September 1, 2020, to October 31, 2021. Data were collected through nationwide surveys in May and October 2021 from the 100 members of the Korean Retinal Society. Patients were diagnosed with fungal endophthalmitis resulting from the use of the viscoelastic material sodium hyaluronate (Unial [Unimed Pharmaceutical Inc]). Data were analyzed from November 1, 2021, to May 30, 2022. Main Outcomes and Measures The clinical features and causative species were identified, and treatment outcomes were analyzed for patients who underwent 6 months of follow-up. Results The fungal endophthalmitis outbreak developed between September 1, 2020, and June 30, 2021, and peaked in November 2020. An official investigation by the Korea Disease Control and Prevention Agency confirmed contamination of viscoelastic material. All 281 eyes of 265 patients (mean [SD] age, 65.4 [10.8] years; 153 female individuals [57.7%]) were diagnosed with fungal endophthalmitis, based on clinical examinations and supportive culture results. The mean (SD) time period between cataract surgery and diagnosis was 24.7 (17.3) days. Patients exhibited characteristic clinical features of fungal endophthalmitis, including vitreous opacity (212 of 281 [75.4%]), infiltration into the intraocular lens (143 of 281 [50.9%]), and ciliary infiltration (55 of 281 [19.6%]). Cultures were performed in 260 eyes, and fungal presence was confirmed in 103 eyes (39.6%). Among them, Fusarium species were identified in 89 eyes (86.4%). Among the 228 eyes included in the treatment outcome analysis, the mean (SD) best-corrected visual acuity improved from 0.78 (0.74) logMAR (Snellen equivalent, 20/120 [7.3 lines]) to 0.36 (0.49) logMAR (Snellen equivalent, 20/45 [4.9 lines]) at 6 months. Furthermore, disease remission with no signs of fungal endophthalmitis (or cells in the anterior chamber milder than grade 1) was noted in 214 eyes (93.9%). Conclusions and Relevance This was a retrospectively reviewed case series of a fungal endophthalmitis outbreak resulting from contaminated viscoelastic material. Findings of this case series study support the potential benefit of prompt, aggressive surgical intervention that may reduce treatment burden and improve prognosis of fungal endophthalmitis caused by contaminated medical products.

Abstract
OBJECTIVES To analyze the epidemiologic features, culture positivity, the fungal spectrum of different sites of ocular infection in North China over 20 years from 2001 to 2020. METHODS 11, 635 patients suspected of ocular fungal infection were reviewed. The demographic profile, fungal positive culture rate among different sites, the distribution, and trends of main pathogens among cornea and intraocular fluid were analyzed. RESULTS Among 11, 635 samples, the positive culture rate of ocular fungal infection was 23.6%. Most of samples (83.1%) were from cornea, and their culture positivity was 26.9%. Fungal keratitis occurred more often during the harvesting season (October to December; 34.0%) than in other seasons (average: 22.0%). Fusarium sp. (53.2%), Aspergillus sp. (15.9%) and Alternaria sp. (12.5%) were the most common fungal species of ocular mycotic infections in the past two decades in north China. 2562 organisms were identified from cornea, of which 1443 (56.3%) were Fusarium sp., 403 (15.7%) and 329 (12.8%) were Aspergillus sp., and Alternaria sp., respectively. Of the 120 fungi isolated from the intraocular fluid, the most common was Aspergillus sp. (33.3%), followed by Fusarium sp. (24.2%) and Candida sp. (15.0%). CONCLUSIONS Fusarium sp., Aspergillus sp. and Alternaria sp. were the most common organisms in cases of fungal keratitis, while Aspergillus sp., Fusarium sp. and Candida sp. were the most frequent isolates for fungal endophthalmitis.

Abstract
Purpose: To report six cases of exogenous fungal endophthalmitis developed after cataract surgery.Case summary: Over about 1 month, eight patients were referred to our hospital under suspicion of fungal endophthalmitis arose after cataract surgery. We performed vitrectomy and intraocular lens removal. We intraoperatively sampled the anterior chamber, vitreous cavity, or intraocular lens surface, and performed staining and culture tests. Before the culture test results were available, we commenced empirical treatment under suspicion of fungal endophthalmitis (based on the clinical features). Five eyes were male and three female (eight eyes of eight patients); the mean patient age was 64 years. The time from cataract surgery to the commencement of appropriate treatment ranged from 13 to 36 days (average 28 days). The culture tests revealed Fusarium species in six of the eight patients. At the 1-month postoperative follow-up of these six patients, the best-corrected visual acuities were 20/20 (one eye), 20/40 (two eyes), 20/50 (one eye), and 20/100 (two eyes).Conclusions: Fungal endophthalmitis is very rare after cataract surgery but is associated with poor visual prognosis and requires long-term treatment. If fungal endophthalmitis is suspected, aggressive treatment with an appropriate selection of medication is important.

Abstract
Fungal endophthalmitis is one of the leading causes of vision loss worldwide. Post-operative and traumatic injuries are major contributing factors resulting in ocular fungal infections in healthy and, more importantly, immunocompromised individuals. Among the fungal pathogens, the Aspergillus species, Aspergillus fumigatus, continues to be more prevalent in fungal endophthalmitis patients. However, due to overlapping clinical symptoms with other endophthalmitis etiology, fungal endophthalmitis pose a challenge in its diagnosis and treatment. Hence, it is critical to understand its pathobiology to develop and deploy proper therapeutic interventions for combating Aspergillus infections. This review highlights the different modes of Aspergillus transmission and the host immune response during endophthalmitis. Additionally, we discuss recent advancements in the diagnosis of fungal endophthalmitis. Finally, we comprehensively summarize various antifungal regimens and surgical options for the treatment of Aspergillus endophthalmitis.

Abstract
PURPOSE To report the clinical profile and treatment outcomes of patients with culture-positive Acremonium keratitis. METHODS This is a retrospective observational study. Medical records of all patients treated in a tertiary eye hospital for culture positive infective keratitis from March 2016 to February 2021 were screened, of which those positive for Acremonium species on fungal culture were reviewed. Demographic details, clinical presentation, clinical course, treatment given, total follow-up duration, time taken for ulcer to heal, scar size, and final visual acuity in the last follow-up were recorded. RESULTS Fifty three cases of fungal keratitis caused by Acremonium species were identified, 22 females and 31 males, with average age of 46.39±18.64 years. The mean duration of symptoms being 54.47±50 days. Only five patients had a history of trauma with vegetative matter. Clinical presentation of patients showed a large number of variations, with 2 patients presenting as peripheral ulcerative keratitis and 1 with epithelial plaque. The mean visual acuity of patients at presentation was 2.43±0.46 logMAR units. Thirty-three of 53 patients presented with perforated corneal ulcer and underwent penetrating keratoplasty; 20 patients were medically managed on topical voriconazole 1%, natamycin 5%, and oral voriconazole. The mean duration of healing of epithelial defect was 95±60.62 days (range 60-165 days). CONCLUSION Acremonium keratitis has a long and indolent course. A prolonged combination therapy of natamycin and voriconazole seems to be effective in the management. A delay in the diagnosis of Acremonium keratitis often leads to clinical worsening requiring keratoplasty.

Abstract
We report three cases of refractory chronic endophthalmitis after cataract surgery presenting to a referral center, and with repeated negative cultures. Initial treatment consisted of intravitreal and systemic antibiotics, with partial improvement. After subsequent worsening, pars plana vitrectomy, intraocular lens explantation and en bloc capsulectomy were performed. Histopathological examination revealed multiple filamentous fungal structures, sequestered between anterior/posterior lens capsule in all cases. Chronic postoperative fungal endophthalmitis may manifest with negative cultures possibly associated with sequestration of the microorganism into the capsular bag. Careful histopathological examination of lens capsule in these cases may be essential for a definite diagnosis.

Abstract
The focus of the current review is multi-fold and compares the diversity and abundance of fungi on the ocular surface by the conventional culture-based method with the more sensitive, high throughput, culture-independent NGS method. The aim is to highlight the existence of a core ocular mycobiome and explore the transition of the ocular fungal microbiota from the normal eye to the diseased eye. PubMed, Google Scholar and Medline were used to search for publications and reviews related to cultivable fungi and the mycobiome of the normal and diseased eye. The conventional cultivable approach and the NGS approach confirm that the eye has its own mycobiome and several confounding factors (age, gender, ethnicity etc.) influence the mycobiome. Further, dysbiosis in the mycobiome appears to be associated with ocular diseases and thus impacts the health of the human eye. Considering that the mycobiome of the eye is influenced by several confounding factors and also varies with respect to the disease status of the eye there is a need to extensively explore the mycobiome under different physiological conditions, different ethnicities, geographical regions etc. Such studies would unravel the diversity and abundance of the mycobiomes and contribute to our understanding of ocular health. Research focused on ocular mycobiomes may eventually help to build a targeted and individualized treatment.

Abstract
Endophthalmitis is a serious ophthalmologic condition involving purulent inflammation of the intraocular spaces. The underlying etiology of infectious endophthalmitis is typically bacterial or fungal. The mechanism of entry into the eye is either exogenous, involving seeding of an infectious source from outside the eye (e.g., trauma or surgical complications), or endogenous, involving transit of an infectious source to the eye via the bloodstream. The most common organism for fungal endophthalmitis is Candida albicans. The most common clinical manifestation of fungal endophthalmitis is vision loss, but other signs of inflammation and infection are frequently present. Fungal endophthalmitis is a clinical diagnosis, which can be supported by vitreous, aqueous, or blood cultures. Treatment involves systemic and intravitreal antifungal medications as well as possible pars plana vitrectomy. In this review, we examine these essential elements of understanding fungal endophthalmitis as a clinically relevant entity, which threatens patients’ vision.

Abstract
Background The goals of this work were to report the demographic characteristics of patients with clinically diagnosed endophthalmitis with or without intraocular foreign bodies (IOFBs) and to analyze the causative microorganisms. Methods A retrospective analysis was conducted on 1257 patients with clinically diagnosed posttraumatic endophthalmitis who were admitted to Zhongshan Ophthalmic Center between January 1, 2013, and August 31, 2020. Results Of the 1257 patients with clinically diagnosed posttraumatic endophthalmitis, 452 (36.0%) patients had IOFBs. Male dominance was more common among the patients with IOFBs than the patients without IOFBs. The average age of the patients with IOFBs was older than that of the patients without IOFBs. The most common microbial pathogens in these two groups were Gram-positive cocci and Gram-negative bacilli. Gram-positive bacilli were more common in the patients with IOFBs than in those without IOFBs (17.9 vs. 9.4%), and Bacillus spp. accounted for 12.6 and 5.5%, respectively. Fungi were less abundant in the patients with IOFBs than in those without IOFBs (8.0 vs. 15.6%). Conclusions Patients with IOFBs were mostly male and older than those without IOFBs. Gram-positive bacilli were more common and fungi were less common in patients with IOFBs than in those without IOFBs.

Abstract
This study aimed to investigate the efficacy of intravitreal povidone-iodine (PI) administration for the treatment of Candida albicans endophthalmitis. Forty New Zealand white rabbits were divided into four groups (n = 10 per group). After the induction of endophthalmitis using Candida albicans, groups A, B, and C received single intravitreal injections of 0.035 mg voriconazole, 0.3 mg PI, and their combination, respectively. Rabbits that were administered sham injections were in group D as controls. Fundus photography, vitreous culture, electroretinography (ERG), and histologic examinations of the retina were conducted on day 7. The anterior chamber flare (grade 0 to 4), severity of iritis (grade 0 to 4), and vitreous opacity (grade 0 to 3) were scored. Candida albicans was cultured in the vitreous sample. On day 7, the vitreous opacities were found in all groups. Compared to that in group D, groups A, B, and C showed a lower score for flare (p < 0.001) and iritis (p < 0.001) and less fungal growth in the vitreous culture (n = 2, 1, 1, and 10 in groups A, B, C, and D, respectively; p < 0.001). Furthermore, ERG and histologic findings demonstrated less affected a- and b-waves and damaged retinal tissues in groups A, B, and C. However, these findings were not different among groups A, B, and C. PI significantly improved Candida albicans endophthalmitis, and the effect was comparable that of the voriconazole, although some vitreous opacities remained. No synergistic effect of the combination of PI and voriconazole was observed. Intravitreal PI may be useful to treat Candida albicans endophthalmitis.

Abstract
Trichophyton species is a dermatophytic fungus commonly found in the skin, nails, hair, and other organic matters such as palm trees and soil. We report a rare case of a 23-year-old man who had a penetrating injury to the eye from the leaves of a palm tree and subsequently developed exogenous endophthalmitis. Culture from the vitreous tap revealed Trichophyton sp as the causative organism. Early vitrectomy and adequate intravitreal injection of amphotericin B resulted in good visual outcomes in an otherwise blinding condition. This is the first reported case of exogenous endophthalmitis secondary to Trichophyton species. Early diagnosis and prompt treatment may help improve visual outcomes.

Abstract
Purpose: To analyse clinico-microbiological profile, antimicrobial susceptibilities, and visual prognostic factors in post-traumatic endophthalmitis (PTE).Methods: Retrospective clinico-microbiological data analysis for five years (2014-18). Prognostic factors for visual outcomes were analysed by multivariate logistic regression analysis.Results: Four hundred and eighteen patients with clinically diagnosed PTE were analysed. Culture positivity was found in 46.7% samples (44.5% vitreous, 83.3% non-vitreous). Pathogens isolated were Gram positive cocci (GPC, 49.3%, good susceptibility to vancomycin/cefazolin), Gram negative bacilli (GNB, 28.1%, <90% susceptibility to all antibiotics and 25.8% multidrug resistance), Gram positive bacilli (13.1%) and fungi (9.5%). Poor visual prognosis was associated with culture positivity, fungal or polymicrobial PTE, poor view of fundus and presence of membranes on ultrasound scans.Conclusion: GPC and GNB are the predominant pathogens in PTE, with GNB most commonly multidrug resistant. Culture positivity, polymicrobial and fungal PTE, poor view of fundus and vitreous membranes are markers of poor visual outcome.

Abstract
Purpose: To identify the bacterial and fungal pathogens in ocular samples of clinically suspected endophthalmitis patients by conventional culture methods and 16S and 28S rDNA gene sequencing respectively. Methods: A total of 88 patients with clinically suspected endophthalmitis were included in this study. Under sterile operating conditions, a vitreous fluid (0.1-0.2 ml) was obtained by pars plana vitrectomy procedure. The samples were processed for conventional microbiology methods and PCR. PCR targeting 16S rDNA gene for bacteria and 28S rDNA gene for fungus were performed individually using the MightyAmp DNA Polymerase Ver. 2 (TaKaRa China) kit. The PCR amplified samples were sequenced and aligned using CLUSTAL-W tool. The phylogenetic tree was constructed by Neighborhood joining along with the reference sequences downloaded from NCBI database using MEGA X software. Results: 67 Post-operative, 12 Endogenous and 9 traumatic endophthalmitis patients were included as study subjects. By the direct culturing bacterial growth was observed in 17 samples and fungal growth in three samples. PCR was positive for all the culture positive samples, in addition 14 were positive in culture negative samples. The predominant species identified in gram-positive bacteria were Staphylococcus spp., and Pseudomonas spp. in the gram-negative group. Both PCR and culture identified only three samples positive for fungal pathogens which were identified as Aspergillus fumigatus, Candida albicans, and Exerohilum rostratum. Conclusions: PCR based molecular diagnosis is more sensitive than the conventional gold standard culture methods in endophthalmitis. Bacterial pathogens were found to be the predominant in causing endophthalmitis than fungal pathogens.

Abstract
Exogenous fungal endophthalmitis (EXFE) represents a rare complication after penetrating ocular trauma of previously unresolved keratitis or iatrogenic infections, following intraocular surgery such as cataract surgery. The usual latency period between intraocular inoculation and presentation of symptoms from fungal endophthalmitis is several weeks to months as delayed-onset endophthalmitis. Aspergillus spp., is the most common causative mould pathogen implicated in this ocular infection and early diagnosis and prompt antimicrobial treatment, concomitantly in most cases with expert surgical attention, reduce unfavorable complications and increase the possibility of eye function preservation. Topical, intravitreal and systemic antifungal molecules are the mainstay of a medical approach to the disease and azoles, polyenes and in particular cases echinocandins are the pharmacological classes most commonly used in clinical practice. This review discusses pharmacokinetics and pharmacodynamic of antifungal agents in their principal modes of administration with a focus on their ability to achieve high drug concentration in the vitreous and ocular tissues.

Abstract
Background To evaluate the effect and prognostic factors of vitrectomy combined with intravitreal antifungal therapy for posttraumatic fungal endophthalmitis in Eastern China. Methods We retrospectively reviewed the medical records of patients who developed fungal endophthalmitis after penetrating ocular trauma at an ophthalmic center in Eastern China. All patients underwent vitrectomy and intravitreal injection of antifungal drugs. Results Thirty-five patients (35 eyes) were included. Twelve eyes suffered plant trauma, 17 eyes metal trauma, and 6 eyes other trauma. The culture results for all 35 eyes showed filamentous fungi, including Aspergillus in 26 eyes (74.3%). Twenty-three eyes underwent vitrectomy once and 12 eyes were treated twice. Four eyes were iridectomized because of a fungal lesion behind the iris. Fungal endophthalmitis was effectively controlled in 33 eyes (94.3%), whereas 2 eyes were ultimately enucleated. Visual acuity was significantly better after treatment than before treatment (P = 0.0006). According to the preoperative vision, the affected eyes were divided into two groups: group 1A (light perception) and group 1B (better than light perception). The final visual acuity in group 1B was significantly better than that in group 1A (P = 0.0289). Conclusions Vitrectomy combined with intravitreal antifungal therapy is an effective treatment for posttraumatic fungal endophthalmitis. Preoperative visual acuity is a significant factor affecting the prognosis of visual acuity.

Abstract
PURPOSE: The aim of this study is to report the anatomical and functional outcome, microbiology profile and treatment used for endophthalmitis in Oman. DESIGN: The study design involves retrospective descriptive multicenter study. METHODS: Demographic and clinical data of patients diagnosed with endophthalmitis over a period of 9 years were collected in three tertiary hospitals in Oman. RESULTS: A total of 50 endophthalmitis cases were included in the study. Exogenous endophthalmitis was diagnosed in 48 cases, whereas 2 cases were endogenous endophthalmitis. Culture-positive cases constituted 16 cases (32%) out of these, 12 cases were Gram-positive, 3 cases were Gram-negative and one case had a positive fungal culture. Immediate first-line treatment was vitreous tap and inject in 33 eyes and vitrectomy in 13 eyes. In 45 eyes in which the visual acuity (VA) was recorded; VA after treatment improved in 22 eyes (49%), remained the same in 16 eyes (36%) and worsened in 7 eyes (16%). CONCLUSION: Although endophthalmitis is rare, it is a devastating ocular emergency. Early diagnosis and prompt intervention are crucial in management. Awareness among the patients undergoing intraocular surgeries about this rare condition is very crucial. Moreover, frontline health-care providers must be aware and critical if they encounter patients with suspicion of endophthalmitis as early recognition, prompt referral, and timely treatment are the key for better visual prognosis. Finally, establishing a National Endophthalmitis Registry is recommended as it will help analyze the incidence, treatment instituted and the outcome of this condition across Oman.

Abstract
This is a literature review of 31 case series of endogenous endophthalmitis (EE) published in the last ten years, identified from a literature search of several databases (PubMed, EMBASE, and the Cochrane Library). While diabetes mellitus and malignancies remain the most frequently associated medical conditions, intravenous drug use is a significant risk factor (especially in the last years, in studies from Western countries). Ophthalmologic screening is recommended for candidaemia, but not in patients with sepsis of other aetiologies (however, the physician treating patients with sepsis must be well aware of EE). The most frequent Gram-positive microorganisms that cause EE are Staphylococcus and Streptococcus; the most frequent Gram-negative organism is Pseudomonas, and yeasts, probably Candida, usually cause fungal infections. In all-cause EE, prognostic factors of better visual outcomes are initial VA better than counting fingers, performing a pars plana vitrectomy (PPV), performing an intravitreal injection within the first 24 hours after clinical diagnosis, and the presence of a focal type of EE. In endogenous fungal endophthalmitis, more than 1/4 of patients have bilateral involvement. Blood samples have a low rate of positivity. Yeasts remain the most prevalent cause. Many authors report using azoles and echinocandins for systemic therapy (and voriconazole for intravitreal injections). Although PPV was performed in small proportions of eyes, the anatomical success rate is quite high. Klebsiella pneumoniae is an important cause of EE in Southeast Asia (and probably an emergent etiology in other regions), which is frequently associated with diabetes. There is a robust association with pyogenic liver abscess (PLA) (but in up to half of the cases, the diagnosis of EE precedes that of PLA). Blood cultures have a high diagnostic yield, while vitreous samples have a low yield. K. pneumoniae may carry antibiotic resistance. Anatomical and functional success rates are small, but they may be improved with PPV.

Abstract
IMPORTANCE Fungal endophthalmitis is an uncommon and serious intraocular infection, often with poor outcomes. This study examines the trend in this disease over 20 years, to inform clinician decision-making and optimize patient outcomes. BACKGROUND Due to infrequent presentation of fungal endophthalmitis, there is limited understanding to formulate a standardized approach to management. DESIGN A prospective case series over the period January 1, 1999 to December 31, 2018. PARTICIPANTS Patients with clinically diagnosed fungal endophthalmitis managed at the Royal Victorian Eye and Ear Hospital, Melbourne, Australia. METHODS Review of the Victorian Endophthalmitis Registry for endophthalmitis episode of each patient. MAIN OUTCOME MEASURES Patient demographics, co-morbidities, visual acuity (VA) at presentation, aetiology, treatment, microbiology results and final VA outcome. RESULTS Eighty-four cases of fungal endophthalmitis were identified over the study period with a median age of 43.5 years [IQR 30.8-63.0]. Then, 65.5% (n = 55) of patients were male; 81.0% (n = 68) of these cases were secondary to endogenous causes, of which 55.9% were associated with intravenous drug use (IVDU). Among the exogenous causes, penetrating eye injury (56.3%) was the most common aetiological factor. Thirty-nine patients (46.4%) grew Candida species from ocular fluid specimens, all of which were sensitive to fluconazole. CONCLUSION AND RELEVANCE Our case series provides important insights into fungal endophthalmitis-a high degree of suspicion for fungal endophthalmitis in patients with history of IVDU, and relatively good outlook for vision when Candida is the causative organism. This should allow institutions to implement a standardized management strategy based on evidence.

Abstract
Background To report a case of lenticular infection caused by Aspergillus, which was diagnosed 13 weeks after traumatic corneal laceration. Case presentation A 60-year-old woman presented with traumatic corneal laceration including anterior lens capsule rupture and traumatic cataract after being hit with a chestnut in the right eye. There were multiple injuries due to tiny thorns of the chestnut, including the conjunctiva, sclera, cornea, and anterior lens capsule. But no visible foreign body was detected by slit-lamp examination. Topical corticosteroid was prescribed to resolve the conjunctival inflammation induced by the thorns of chestnut, which could have caused persistent irritation. As conjunctival injection and edema being decreased during outpatient clinical follow-up, embedded conjunctival foreign body was detected and surgically removed (1st surgery). Approximately 10 weeks after the trauma, severe inflammation of the anterior segment accompanied with hypopyon developed suddenly and at the same time embedded scleral foreign body was revealed. After removal of scleral foreign body (2nd surgery), unspecified mold species was cultured from the scleral foreign body in SDA (Sabouraud dextrose agar) plate. Suspicious corneal foreign body was removed as 3rd surgery and phacoemulsification of traumatic cataract was planned as 4th surgery. Aspergillus was finally detected from removed anterior capsule and fibrotic membrane during the operation. Fungal infection resolved successfully after administration of topical (1% voriconazole and 5% natamycin) and systemic (fluconazole) antifungal agents and phacoemulsification of traumatic cataract. Conclusion Chestnut thorns can damage multiple ocular tissues simultaneously. Lens capsular rupture could result in fungal inoculation and lead to delayed lenticular fungal infection with complicated cataract formation. In cases of ocular trauma due to organic substances such as thorns and branches, the possibility of fungal infection should be considered.

Abstract
PURPOSE The aim of this study was to describe the clinical presentations, management and factors determining outcomes of Aspergillus endophthalmitis. DESIGN Retrospective, interventional, multicentric case series. METHODS The study included 91 eyes of 91 patients with culture-proven Aspergillus endophthalmitis. Anterior chamber fluid and/or vitreous and/or intraocular lens were submitted for microbiological evaluation in all cases. The data analysis included patient demography, clinical presentations, interventions, and final treatment outcomes. The main outcome measures were the final visual acuity and the globe salvation. The factors determining better visual and/or anatomical outcomes were analyzed. RESULTS The mean age of the patients was 39.71 ± 20.16 years (median 40 years, range 3-76 years). By etiology, the primary event before the endophthalmitis was trauma (42; 46.15%) eyes, cataract surgery (acute-onset: 30; 32.96% and delayed-onset: 6; 6.59%) eyes, endogenous (10; 10.98%) eyes, and cornea surgery (3; 3.29%) eyes. The mean follow up was 5.78 ± 6.74 months (median 3, range 0.5-40 months). The odds of a favorable visual outcome were presenting vision > hand motions [odds ratio (OR) = 3.33, P = 0.02], absence of corneal infiltrate (OR = 5.4, P = 0.03), vitrectomy instead of a vitreous tap only (OR = 4.26, P = 0.03), administration of intravitreal voriconazole (OR = 3.63, P = 0.02), and absence of fungal elements on primary microscopy (OR = 3.42, P = 0.02). CONCLUSIONS Early vitrectomy and intravitreal voriconazole yielded better anatomic and functional outcomes in Aspergillus endophthalmitis. Favorable visual outcome was achieved in a fifth of the eyes and globe was salvaged in two-thirds of the eyes.

Abstract
Fungal endophthalmitis is subsequent to endogenous or exogenous infection and represents an important complication of ocular surgery which may lead to significant visual loss and blindness. The prognosis is poor because of delayed diagnosis and limited availability of effective antifungal drugs with good ocular penetration. Furthermore, the critical issue in diagnosing fungal infection of the eye is microbiological identification of the etiologic agent in clinical samples. Aspergillus is among the most frequent isolated organisms in fungal endophthalmitis. Early diagnosis is essential to prevent severe complications and blindness. Treatments include local, systemic and surgical therapeutic strategies. The purpose of the present review is the analysis of the current procedures adopted to promptly diagnose and treat Aspergillus endophthalmitis.

Abstract
BACKGROUND Fungal endophthalmitis is a sight-threatening disease associated with high morbidity and Aspergillus sp. is the most common causes. Voriconazole (VCZ) and Amphotericin B (AmB) are the most used antifungal drugs, while head-to-head comparison for in vivo intravitreal efficacy is still unknown. This study was aimed to compare the efficacy of both agents against Aspergillus flavus.
METHODS A randomized, masked, controlled-experimental study was conducted on 15 albino New Zealand white rabbits. Endophthalmitis was induced by intravitreal inoculation of Aspergillus flavus. Intravitreal injection was given 24 hours post-inoculation, the rabbits were divided into three groups; 100 μg/0.1 ml VCZ intravitreal injection, 5 μg/0.1 ml AmB, and control. Clinical evaluation of corneal opacity, aqueous cells and flare, and vitreous opacity using Yang’s method of quantification were performed at day 1, 3, 5, 7, and 10 after treatment. Mycology quantitative analysis and histopathological examination were performed at the final evaluation.
RESULTS Clinical evaluation showed improvement of inflammation in the VCZ and AmB treatment groups (Δ score −2.1 [2.8] and −1.0 [3.2]) compared with the control group (Δ score 0.8 [3.1]). Although the VCZ group demonstrated a better clinical response with less inflammation and relatively intact retina structures in the histopathology result. Number of fungal colony was significantly less in AmB group (CFU/0.1 ml, p < 0.05).
CONCLUSIONS Favorable clinical improvement was shown in VCZ group compared to AmB group. Intravitreal VCZ showed a better clinical response tendency for Aspergillus flavus-induced endophthalmitis in rabbits.

Abstract
Despite Aspergillus being the leading cause of exogenous fungal endophthalmitis following traumatic injury to the eye, its pathogenesis is not fully understood. In the current study, we developed a murine model of Aspergillus fumigatus (AF) endophthalmitis and investigated the disease pathobiology. Endophthalmitis was induced by intravitreal injection of Aspergillus spores in immunocompetent and immunocompromised (neutropenic) C57BL/6 mice, and disease severity was assessed by eye exam, fungal burden estimation, and histological examination. Our data showed that AF infection caused a time-dependent increase in corneal haze, opacity, and hypopyon beginning at two days post-infection (DPI). The fungal burden in infected eyes of immunocompetent mice peaked at 2 DPI and declined over 9 DPI. AF-infected neuroretina exhibited induction of innate immune response via upregulation of Toll-like receptors (TLRs) and inflammatory mediators (TNFα, IL-1β, and IL6), and increased polymorphonuclear neutrophil (PMN) infiltration. Histological analysis revealed heavy cellular infiltrates in the vitreous cavity as well as disruption of normal retinal architecture and increased retinal cell death. Neutropenic mice exhibited severe disease pathology with the prolonged fungal burden and increased inflammatory mediators. Our study described the first immunocompetent murine model of exogenous AF endophthalmitis and demonstrated an important role of neutrophils in innate defense against fungal endophthalmitis.

Abstract
Purpose To describe clinical presentations and comparative outcomes of primary versus deferred intraocular lens (IOL) explantation in delayed-onset endophthalmitis. Methods In this retrospective study, a total of 77 eyes of 77 patients that were diagnosed clinically as delayed-onset endophthalmitis and underwent IOL explantation from January 1990 to January 2018 were included undiluted vitreous biopsy and IOL were subjected to microbiologic evaluation. Duration of symptoms, presenting visual acuity, organisms isolated, time to IOL explantation, time to endophthalmitis, resolution after explantation, number of repeat intravitreal injections, and final visual acuity were compared in the primary and the deferred IOL explantation groups. Results There were primary and deferred IOL explantations. Interval between inciting event and endophthalmitis, between onset of symptoms to presentation, total follow-up, complication rate, and final visual acuity was comparable between the two groups. Median time to IOL explantation in the deferred group was 70 days. Between the primary and deferred IOL explantation groups the number of repeat intravitreal injections was 0.58 ± 0.86 and 2.62 ± 1.78 respectively, (P < 0.0001, 95% confidence interval, CI 2.00-2.22); the number of days to resolution after IOL explantation was 35.16 ± 14.26 and 55.5 ± 8.24 respectively, (P < 0.0001, 95% CI 15.22-25.45). Conclusion Early IOL explantation in delayed-onset endophthalmitis causes faster clinical resolution and reduces the number of repeat intravitreal injections. Final visual improvement, however, may be unaffected.

Abstract
Purpose To present a case of fungal endophthalmitis with a novel organism and our management. Observations A 46 year old male presented with delayed-onset acute endophthalmitis 6 weeks after routine phacoemulsification and intraocular lens implantation. Initial treatment with intravitreal antibiotics did not improve his condition. With repeated vitreal taps, the causative organism was eventually identified as a fungus, Pseudozyma aphidis. Treatment with oral and intravitreal voriconazole, as well as pars plana vitrectomy, led to resolution of the endophthalmitis and recovery of vision to 20/25. Conclusions and importance Fungal endophthalmitis is a rare, potentially blinding complication of cataract surgery. We report our approach to this previously unreported organism, that led to an excellent visual outcome. There are no specific guidelines for fungal endophthalmitis. The management approach has to be tailored to the clinical response and emerging laboratory data from the microbiologist. Identification of the organism will require specialist laboratory references that may not be available in all hospitals. Ophthalmologists must work closely with microbiologists in order to ensure an optimal outcome.

Abstract
Purpose To describe the spectrum of bacterial and fungal pathogens in cases of endophthalmitis requiring evisceration and report their antimicrobial susceptibilities. Methods Retrospective, consecutive, and descriptive case series of endophthalmitis that underwent evisceration from January 2004 to December 2017. Vitreous samples from all patients had been investigated for bacteria and fungus using institutional protocol. Bacterial isolates were identified using analytical profile index (API) system until 2010 and Vitek-2 compact system (bioMérieux, France), thereafter. The susceptibility of bacterial isolates to a variety of antibiotics was determined by the Kirby-Bauer disk-diffusion method. Results Of 791 cases reviewed, culture positivity was reported in 388 cases (48.92%). Commonest clinical setting of endophthalmitis necessitating evisceration was post-microbial keratitis (58%), followed by post-trauma and post-cataract surgery (14–15%). The commonest isolate was Streptococcus pneumoniae, seen in 68 samples overall (17.52%). One hundred and eighty-three isolates (47.16%) were gram-positive, 86 (22.16%) were gram-negative, and fungi constituted 137 (35.3%) isolates. Streptococcus pneumoniae was the commonest gram-positive bacterial isolate seen in 68/183 samples (37.15%). Among gram-negative organisms, the commonest was Pseudomonas aeruginosa seen in 47/86 (54.65%). Aspergillus spp. formed the commonest fungal isolate, 58/137 (42.33%). The susceptibility of the gram-positive bacteria was highest with vancomycin, 136/147 (92.51%) and for gram-negative bacteria was seen best with imipenem 24/29 (82.75%). Susceptibility to ceftazidime was 31/61 (50.81%) in 31/61. Conclusion Endophthalmitis due to Pneumococci, Aspergillus, and Pseudomonas can be very fulminant and progress to require evisceration in spite of prompt and appropriate treatment.

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: Fusarium spp. are leading fungal pathogenes in contact lens associated keratitis and may evoke endophthalmitis. Since Fusarium spp. are highly resistant to antifungal drugs, globe integrity is threatened. Case: A woman developed fungal anterior chamber involvement after contact lens associated corneal ulcer formation. She presented with a painful eye with hypopyon and a mass presumably of fungal origin growing on the iris and anterior lens capsule. A biopsy confirmed Fusarium solani. Only multiple lavages of the anterior segment with Amphotericin B achieved convalescence. Conclusion: In the initial stage of contact lens associated keratitis, it is often hard to differentiate between etiology. However, keratitis which are treatment resistant to antibacterials are suspicious for fungal origin. For proper treatment, identification of pathogen is crucial. Due to poor tissue penetration of the lipophilic anti-fungal agents and slow fungal replication rate, multiple lavages of the anterior chamber are often required to handle fungal infections.
