No study, however has proven that this method has any prophylactic effect on the prevention of endophthalmitis. Several cases were associated with risk factors for fungal infections, such as malnutrition, long-term corticosteroid inhalation, and diabetes (Huang etal., 2010; Xie etal., 2018; Wang etal., 2019). [ 1] Aggressive therapy and early vitrectomy may be considered in endogenous endophthalmitis caused by virulent pathogens such Pseudomonas aeruginosa and in cases of Klebsiella endophthalmitis. [7, 52] In these circumstances and in the absence of any prospective studies, careful evaluation of each case may be recommended by the treating ophthalmologist. However, facial cellulitis can be a direct or indirect causative infection. [10] Since systemically administered antibiotics do not reach sufficient concentrations in vitreous, intravitreal injections have become the accepted primary route of delivery biotic delivery. Patients having full blown endophthalmitis within days after the surgery often have infection due to Staphylococcus or Streptococcus species or alpha-hemolytic Streptococci species of the viridans group during which vision can be lost over 12 hours if no intervention is undertaken. By Brygida Kwiatkowska and Maria Maliska. Colonies on normal PDA medium and water plate grew slowly, and no conidia were seen. [2, 3] Gram-negative species may account for up to 6% of endophthalmitis cases. Posterior capsulotomy should be performed and pus and the fibrin material need to be aspirated. J. Dermatol. Computed tomography (coronal view) of his brain revealed evidence of septic emboli (c). WebEndophthalmitis symptoms may be severe and include severe eye pain, redness in the white of the eye, extreme sensitivity to bright light, decreased vision, and occasionally swelling of the eyelid. [12]. London, SW7 2QJ, [81, 97, 99] Patients with endogenous endophthalmitis who undergo PPV early in the course of endogenous endophthalmitis may end up with some useful vision. Infections due to some pathogens may be very difficult to treat in patients with diabetes and other systemic conditions (Figure 9). The diagnosis was left eye endophthalmitis and left eye blindness, accompanied with progressive worsening of symptoms and lack of ocular preservation value. Infratentorial subdural effusion: an imaging hint of a first-seen intracerebral corynespora cassiicola infection. Figure3 Colony morphology (A) and conidia (B) on PDA medium containing leaf leachate incubated at 28C for 5 days. One is exogenous endophthalmitis, i.e., the infection travels inside the eye through the outside. Symptoms. [81, 99] Endophthalmitis may occur in patients with candidemia depending on the population studied, especially those with an organ transplant and having a highly immunocompromised status. endophthalmitis In some instances, signs of endophthalmits following ocular surgery or trauma may appear soon. A large amount of flocculent milky white pus was seen in the anterior chamber. To date our community has made over 100 million downloads. Risk of developing endophthalmitis has been reported to be lower with the introduction of injectable IOLs as compared with foldable lenses since injectable lenses avoid the contact with ocular surface. Mycol. WebPseudomonas aeruginosa infections of the eye, ear, urinary tract, gastrointestinal tract, and central nervous system. TASS may also be due to agents stuck to devices that have become denatured, the wrong concentration of antibiotics used in the Basic Saline Solution (BSS) irrigating solution during intraocular surgery, use of drugs containing preservatives, BSS made up at the wrong pH, or ethylene oxide residue left on plastics. Additionally, 80% cases of culture-negative endophthalmitis resulted in a final visual acuity of 20/100 or better. Voriconazole (VRC) and amphotericin B (AMB) were the most frequently used agents against this organism, which resulted in successful treatment outcomes in most cases (Supplementary Table2). Natural substrate potato dextrose agar (PDA) agar medium was prepared using 20g of dry powder of PDA medium (Beijing Tiantan Bio) dissolved in 1,000 ml of supernatant of distilled water soaked in dry leaves (Zhang, 2018). When the fundus view is not possible, imaging studies in the form of ultrasonography and computed tomography should be requested. Other strong predictors for poor visual outcome were initial visual acuity of light perception only, older age, corneal ring ulcers, compromised posterior capsule, abnormal intraocular pressure, presence of RAPD, rubeosis iridis, and absence of the red fundus reflex. Left eye evisceration was performed. Following PPV, intra-vitreal antibiotics are injected. Learn more about Syfovre. Symptoms of endophthalmitis include: eye pain; redness; changes in vision; sensitivity to light; Diagnosis and treatment WebEye pain and redness Decreased vision Trouble looking at bright lights (photophobia), usually sudden onset Causes Acute cases of endophthalmitis are caused by gram-positive (or less frequently gram-negative) bacteria and are most often seen within 6 weeks after surgery or trauma to the eye. Predictors of poor visual outcome included IOFB removal 48 hours or later, posterior location and no PPV at the time of initial surgery (Figure 12). Bleb-related endophthalmitis usually follows a chronic course of infection (Figure 8). If any of these investigations yield a positive result, the case can be classified as a proven case of infective endophthalmitis; otherwise the case should be classified as presumed unproven endophthalmitis. [28, 31] Poor prognosis stems from the presence of more virulent pathogens, presence of mixed infections, traumatic tissue injury and the failure to start prophylactic antibiotics. Genomic insight into pathogenicity of dematiaceous fungus corynespora cassiicola. (London, England: Academic Press Inc.), 315322. Suggested medical treatment in these patients include topical, sub-conjunctival and intra-vitreal injection of antibiotics having broad coverage with consideration for corticosteroids in cases of severe inflammation. - American Academy of Ophthalmology It can occur after a penetrating wound of the eye (either surgical or accidental), bacterial infection, or intraocular foreign [12] The infection may also occur following glaucoma surgery, retina surgery and even following strabismus surgery. doi: 10.12998/wjcc.v10.i11.3490. Over the past several decades, sub-conjunctival antibiotics injection has been advocated as a prophylaxis against infection after most of the intraocular surgeries. See panophthalmitis; vitrectomy. For example, acute suppurative endophthalmitis due to Streptococcus pyogenes may occur days after cataract surgery in which case the patient may present with swollen eyelid, opaque cornea, conjunctival chemosis and significant pain. doi: 10.3109/13693786.2011.553635, Raja, H. A., Miller, A. N., Pearce, C. J., Oberlies, N. H. (2017). Post-operative delayed fungal endophthalmitis; photograph (a) showing sectoral iris infiltration with Aspergillus niger requiring pars-plana vitrectomy, total capsulectomy, total iridectomy and removal of intraocular lens, photograph (b) showing white plaque extending from the upper capsule equator caused by Aspergillus terreus requiring 3 PPVs and intra-viteal Amphotericin B injections and eventual enucleation because of recurrent fungal infection. 32 (4), 101298. doi: 10.1016/j.mycmed.2022.101298, Huang, H. K., Liu, C. E., Liou, J. H., Hsiue, H. C., Hsiao, C. H., Hsueh, P. R. (2010). WebEndophthalmitis signs and symptoms may include: Red eyes. Caspofungin appears to have a very good activity against Candida and Aspergillus species and when administered systemically along with Voriconazole, it has been found to be very effective in treating endophthalmitis caused by these organisms. The patient's ocular condition improved dramatically; however, her VA did not improve. [1, 102] Candida albicans is by far the most frequent cause (75-80% of fungal cases), followed by Aspergillus species. In another large population-based review of United States Medicare beneficiary claims between 1994 and 2001 of 447,627 cataract operations, 1026 cases of presumed endophthalmitis were noted and an increased incidence was associated with the introduction of clear cornea incision. Loss of vision. This large study revealed that culture-positive cases were associated with worse presenting visual acuity, higher presenting intraocular pressure, and worse visual outcomes than culture-negative cases. The use of vitrector may be required in cases of infected vitreous. Z., Boehm, E. W., Burgess, T. I., de Gruyter, J., et al. They are thus the second commonest cause of all cases of endophthalmitis. [19] Conjunctival and corneal swabs are usually not helpful, as the correlation with the microorganisms isolated is very low. These antibiotics are administered topically 4-6 times daily. Effective therapy requires proper identification of the causative organisms and their sensitivity to the desired antifungal agents (Figure 13). Incidence, clinical features, causative organisms, and visual outcomes of delayed-onset pseudophakic endophthalmitis. Webendophthalmitis. endophthalmitis It can occur after a penetrating wound of the eye (either surgical or accidental), bacterial infection, or intraocular foreign bodies. RT-PCR can serve as a rapid and reliable tool to detect viable bacteria causing endophthalmitis. C. cassiicola infections are rare in humans. Some clinical laboratories use DNA sequencing as part of routine protocols for fungal identification. [3] Anti-inflammatory therapy in the form of corticosteroids at the time of intra-vitreal antibiotics can limit the tissue destruction by infiltrating leukocytes due to their cytokines. [82, 83] In advanced cases of fungal endogenous endophthalmitis, one may encounter areas of peri-vascular infiltrates, retinal infarction, hemorrhages and retinal necrosis. Endophthalmitis: Pathogenesis, clinical presentation, management 6 and 13 in Supplementary Table2). [60] If trauma takes place in a rural area, there is more likelihood of infection to be a polymicrobial infection. Streptococcus, Pseudomonas, and Serratia cases were associated with poor presenting view of the fundus and worse visual outcomes than coagulase-negative Staphylococcus and Moraxella cases. [13]. Samples of aqueous and vitreous should be collected from these patients for Gram staining, culture, and Polymerase Chain Reaction (PCR) assay. Endophthalmitis is a serious inner eye infection. (2020). Gene sequence analysis provides a powerful tool for fungal species identification, especially molds that fail to sporulate, which were impossible to speciate. Licensee IntechOpen. Significant eye pain. Intracameral antibiotic use for the prevention of cataract surgery-related endophthalmitis is increasing, but has not been universally adopted. Endophthalmitis is a rare but severe disease in ophthalmology. Background Postoperative endophthalmitis is defined as severe inflammation involving both the anterior and posterior segments of the eye after intraocular surgery. In general, systemic therapy must be continued for several weeks to ensure eradication of the infection. Terbinafine (TBF) was successfully used in two cases (nos. Endophthalmitis vs Uveitis Less common causes of endogenous endophthalmitis include orbital and periorbital cellulitis and in rare cases facial cellulitis. The diagnosis was left eye endophthalmitis and left eye blindness, accompanied with progressive worsening of symptoms and lack of ocular preservation value. Clinical features associated with better visual acuity outcomes included better presenting visual acuity, early presentation to the eye clinics, and isolation of a nonvirulent organism. Recent data for the effectiveness of vitrectomy and intra-vitreal antibiotics to save some vision has been encouraging. Written informed consent was obtained from the participant/patient(s) for the publication of this case report. External photograph of a patients right eye who presented with decreased vision, pain, tearing, redness and photophobia several days after having penetrating trauma to his right eye. doi: 10.1093/mmy/myu033, Schoch, C. L., Crous, P. W., Groenewald, J. Vitreous biopsy should be considered because a culture of the vitreous sample is useful for identifying the responsible bacteria. [1, 13] In the late-onset cases of endophthalmitis, the symptoms are milder and Propionibacterium acnes has been reported to be the cause in majority of cases (Figure 7). The word "endophthalmitis" can be broken down in greek to "interior-eye-inflammation" and is used to describe an infection of the vitreous and/or the aqueous humor within the eye. DNA microarray technique may be useful for genetic screening and identification of microorganisms in cases of suspected infectious endophthalmitis. Evaluation and treatment of acute post-operative bacterial endophthalmitis is initiated when such infection is suspected, generally within few hours of patients presentation. Isolation of any bacterial colonies on direct inoculation of agar plates cultured aerobically or anaerobically may be indicative of culture-positive endophthalmitis. A class-wide phylogenetic assessment of dothideomycetes. If indicated, alternative drugs such as Amikacin (400 ug/0.1 mL), might be considered instead of Ceftazidime. External photograph of a patient with history of cataract surgery who presented with severe conjunctivitis, corneal opacification and vascularization was found to have evidence of endophthalmitis. [61, 64] Both can be given systemically and intra-vitreally. J. Nat. General anesthesia may be indicated in cases of severely inflamed eyes. Other risk factors for the development of post-operative endophthalmitis include canaliculitis, acute and chronic dacryocystitis and anti-glaucoma aqueous drainage devices. Because of the conidia of this train, it is probably more likely to be formed on the medium with dead wood degradation component when cultured in vitro, which provides a methodological reference for the culture of similar strains. . One may need to differentiate between the postoperative endophthalmitis from the less common cases of TASS. For prognostic purposes, endogenous endophthalmitis has been classified based on location (anterior or posterior) and extent (focal or diffuse). In these circumstances, removal of the intraocular lens or exchange to prevent recurrent or persistent endophthalmitis may be necessary. Culture results revealed evidence of Enterococcus faecalis and the eye became rapidly phthisical (c). The most common cause of this condition is a bacterial infection after cataract surgery. Vitreous specimens for culture obtained by vitrectomy have been found to be more sensitive in detecting the causative organism than the vitreous needle biopsy. [88] Immediate vitrectomy is performed in eyes with light-perception-only vision at the initial visit. Alkuraya et al, [106] reported a case of culture-positive endophthalmitis after intra-vitreal injection of bevacizumab (Avastin) in a 51-year-old diabetic women. Intraocular penetration of a dirty or soil-contaminated foreign body requires an emergent intervention. These authors reported successful treatment with intra-vitreal (Vancomycin, Ceftazidime) and intravenous antibiotics (Vancomycin, Meropenem). [20], Depending on location, a wide range of organisms have been shown to cause endogenous endophthalmitis. Endophthalmitis is a medical emergency and can result in vision loss. Intra-vitreal Dexamethasone injection (400 mg/0.1 mL) after vitrectomy may lead to a rapid subsidence of the intraocular inflammation. [7] In the adults, early intervention with PPV has been found to be highly effective, no such data has been proven for cases of pediatric endogenous endophthalmitis. Symptoms vary slightly. Physical examination: There was no light perception in the left eye. [33] Specific eyelid or peri-orbital diseases such as blepharitis, ectropion, entropion and paralytic disorders may enhance the chance of post-operative endophthalmitis. Keywords: ocular infection, Corynespora cassiicola, morphology, pseudospores, drug sensitivities, Citation: Wang Q, Wang L, Lian L, Pu X, Tang L, Li Y and Liu Y (2023) Case report: A case of ocular infection caused by Corynespora cassiicola. [1-3] In severe cases, 3-port PPV is recommended depending on the level of visualization. Farming may increase the risk of ocular exposure to Corynespora by rubbing eyes after contact with vegetation. Additional symptoms vary. According to the Endophthalmitis Vitrectomy Study (EVS), [10] a prospective, randomized clinical trial of post-operative acute endophthalmitis, hypopyon was documented in 75% of the enrolled patients and according to the European Society of Cataract and Refractive Surgeons Endophthalmitis Study (ESCRS), hypopyon was present in 72% of patients having endophthalmitis. [1] In the vast majority of cases of endophthalmitis, inflammation is triggered by an infectious agent. doi: 10.1016/j.jinf.2009.11.002, Looi, H. K., Toh, Y. F., Yew, S. M., Na, S. L., Tan, Y. C., Chong, P. S., et al. 9 and 11 in Supplementary Table2) did not respond well (Yan etal., 2016; Arango-Franco etal., 2018). All authors contributed to the article and approved the submitted version. doi: 10.3767/persoonia.2020.44.11, Dixon, L. J., Schlub, R. L., Pernezny, K., Datnoff, L. E. (2009). In contrast, post-traumatic endophthalmitis occurred in 11% of 204 patients in non-rural districts. [85] No eyes that have suffered posterior, diffuse or panophthalmitis has received any useful vision regardless of management. Symptoms. symptoms While it is suggested that the addition of antibiotics to the irrigating solution may have a protective effect, it has not been possible to reduce the incidence of endophthalmitis in any prospective clinical study. Copyright 2023 Wang, Wang, Lian, Pu, Tang, Li and Liu. Patients having chronic dacryocystitis may harbor multiple micro-organisms which may be resistant to the commonly prescribed post-cataract surgery prophylactic antibiotics. Combined applications of morphological and molecular biology techniques facilitate accurate diagnosis of fungal infections. Endophthalmitis Other bacteria include Staphylococcus species, Streptococci, Coliforms, and Clostridium species. Endophthalmitis MIC values to antifungal agents for this organism were reported in four publications (Supplementary Table3). This is particularly true in children because of the variety of pediatric cases and lack of sufficient experience in diagnosing in this age group. [8, 37] Facial cellulitis is rarely reported as a focus of infection leading to endogenous endophthalmitis. Frontiers | Case report: A case of ocular infection caused by Genome-wide analysis of corynespora cassiicola leaf fall disease putative effectors. Blood cultures may be the most frequent means for establishing the infective cause. No use, distribution or reproduction is permitted which does not comply with these terms. Intra-vitreal Dexamethasone at the time of vitreal biopsy and intra-vitreal antibiotics has been found to be very helpful in minimizing uveal tissue damage. Similar to post-operative endophthalmitis, two thirds of the bacteria in post-traumatic endophthalmitis are Gram-positive and 10% to 15% are Gram-negative. Reaction conditions: pre-denaturation at 94C for 2min; denaturation at 94C for 30 s, annealing at 58C for 30 s, extension at 72C for 90s, cycle number 35; extension at 72C for 7min. The most common endophthalmitis symptoms are: Noninfectious (sterile) endophthalmitis may result from various causes such as retained native lens material after an operation or from toxic agents. Fungal DNA extraction kit (EE101, TransGen Biotech, Beijing, China) was used to extract DNA of the isolates. Amplification and direct sequencing of fungal ribosomal RNA genes for phylogenetics, in PCR protocols: a guide to methods and applications. If not diagnosed early on and therapy initiated, endogenous bacterial endophthalmitis usually leads to total loss of vision. CARD9 mutation linked to corynespora cassiicola infection in a Chinese patient. Contact our London head office or media team here. In May 2023, Frontiers adopted a new reporting platform to be Counter 5 compliant, in line with industry standards. Type of infecting organism may have prognostic effect on the final visual outcome. External photographs of a 13-years-old male who presented one week after trauma to his right eye (a and b). Following intraocular surgery, leak-proof closure of the corneal incision is recommended to limit access of microorganisms to the anterior chamber. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. In their case, the patient presented with decreased vision, redness, and mild pain in her eye 3 days after intra-vitreal injection of Avastin for macular edema due to a branch retinal vein occlusion. Fungal keratitis caused by corynespora cassiicola, a plant pathogen. Delayed involvement of the second eye can occur even in patients already being treated with systemic antibiotics.
