Challenging course of endophthalmitis with corneal ulcer following cataract surgery: successful management and visual rehabilitation / Caso desafiador de endoftalmite com úlcera corneal após cirurgia de catarata: manejo bem-sucedido e reabilitação visual

ABSTRACT The objective of this case report was to share the successful management of severe endophthalmitis, aiming at ocular integrity and visual acuity. A 73-year-old man presented with visual acuity of 20/30 in the right eye and 20/200 in the left eye. On the 21st day postoperatively after phacoemulsification in the left eye, he developed symptoms of endophthalmitis, including ocular discomfort, blurred vision, and whitish discharge. Despite negative cultures, his condition worsened, resulting in corneal perforation on the 31st day. Conjunctival flap and penetrating keratoplasty were performed. Currently, the patient maintains a visual acuity of 20/40 in the left eye, with a healthy graft and no signs of failure. Despite the complications, careful follow-up and timely interventions successfully preserved his vision. The use of conjunctival flap during the inflammatory phase was crucial to maintaining ocular integrity. This underscores the importance of different approaches in complex ocular complications, including alternative strategies for ocular protection during active inflammation.

RESUMO O objetivo deste relato de caso foi compartilhar o manejo bem-sucedido de uma grave endoftalmite, visando à integridade ocular e à acuidade visual. Um homem de 73 anos apresentou acuidade visual de 20/30 no olho direito e 20/200 no olho esquerdo. No 21° dia pós-operatório de facoemulsificação em olho esquerdo, ele desenvolveu sintomas de endoftalmite, incluindo desconforto ocular, visão embaçada e secreção esbranquiçada. Apesar de culturas negativas, sua condição piorou, resultando em perfuração corneal no 31° dia. A cobertura conjuntival e a ceratoplastia penetrante foram realizadas. Atualmente, o paciente mantém acuidade visual de 20/40 no olho esquerdo, com enxerto saudável e sem sinais de falha. Apesar das complicações, o acompanhamento cuidadoso e as intervenções oportunas preservaram a visão com sucesso. O uso de cobertura conjuntival durante a fase inflamatória foi crucial para manter a integridade ocular. Isso destaca a importância de diferentes abordagens em complicações oculares complexas, incluindo estratégias alternativas para proteção ocular durante a inflamação ativa.

Efectividad del moxifloxacino intracameral profiláctico para reducir la endoftalmitis posterior a cirugía de cataratas en población chilena / Effectiveness of prophylactic intracameral moxifloxacin to reduce endophthalmitis after cataract surgery

BACKGROUND: Endophthalmitis is a serious infectious complication of cataract surgery, which may lead to vision loss. Aim: To evaluate the effectiveness of intracameral moxifloxacin in reducing endophthalmitis after cataract surgery in Chilean patients. MATERIAL AND METHODS: We reviewed all phacoemulsification surgeries performed between 2012 and 2020 at a public hospital. The use of intraoperative intracameral moxifloxacin and possible surgical complications were recorded. In patients with postoperative endophthalmitis, we reviewed their risk factors and clinical characteristics. RESULTS: In the study, 22,869 phacoemulsification surgeries were registered, with an annual average of 2,541. The use of prophylactic intracameral moxifloxacin started progressively in 2014. In 2018 it was used in 88% of the surgeries. Fifteen eyes evolved with postoperative endophthalmitis, but none of these surgeries used intracameral moxifloxacin. Five and seven cases occurred in 2012 and 2013, respectively. There was a trend favoring moxifloxacin use, as a preventive measure for endophthalmitis, but the difference between groups was not significant (p = 0.56). In the group with endophthalmitis, 33.3% of the eyes were from patients with type 2 diabetes mellitus, in 13.3% there was rupture of the posterior capsule and 60% of the eyes corresponded to female patients. Since 2018 there is no record of endophthalmitis after cataract surgery performed in this center. Conclusions: Intracameral moxifloxacin showed a tendency to reduce the frequency of endophthalmitis after phacoemulsification surgery, but a longer observation period is required to reach statistical significance, due to the low frequency of this complication.

Efectividad de la antibioticoterapia sistémica precoz en pacientes con endoftalmitis postraumática / Effectiveness of the early systemic antibiotic therapy in patients with postraumatic endophthalmitis

Introducción: La endoftalmitis postraumática se define como una marcada inflamación de los fluidos y tejidos de las cavidades intraoculares, provocada por la invasión y replicación de microorganismos después de un traumatismo ocular a globo abierto, lo cual puede ocasionar la pérdida de la visión. Objetivo: Evaluar la efectividad de la terapia antibiótica sistémica precoz en pacientes con endoftalmitis postraumática. Métodos: Se efectuó un estudio cuasiexperimental de 72 pacientes con traumatismo ocular a globo abierto, ingresados en el Centro Oftalmológico del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, desde enero del 2017 hasta mayo del 2019. Se realizó un muestreo aleatorio simple; los pacientes se distribuyeron en 2 grupos: uno de control con 28 integrantes, a los cuales se le administró el tratamiento farmacológico habitual y otro de estudio con 44, quienes además de lo anterior recibieron terapia antibiótica sistémica. Resultados: Predominaron los pacientes masculinos, con edades entre 45 y 54 años (29,5 %); 72,7 % no mostraron antecedentes personales de interés y el trauma ocular ocurrió con más frecuencia en un ambiente rural (77,8 %). La zona 1 fue la más afectada (65,3 %); en 39,3 % de los pacientes la evolución del trauma fue menor de 6 horas, pero en el grupo que no recibió la terapéutica sistémica precoz y presentó endoftalmitis (10,7 %) este tiempo fue mayor, la reparación ocurrió tardíamente. Conclusiones: La terapia antibiótica sistémica precoz fue efectiva en la mayoría de los pacientes que recibieron este tratamiento contra la endoftalmitis postraumática.

Introduction: Postraumatic endophthalmitis is defined as a marked inflammation of the fluids and tissues of the intraocular cavities, caused by the invasion and replication of microorganisms after an ocular traumatism on open globe, that can cause loss of the vision. Objective: To evaluate the effectiveness of the early systemic antibiotic therapy in patients with postraumatic endophthalmitis. Method: A quasi-experiment study of 72 patients with ocular traumatism on open globe was carried out, they were admitted in the Ophthalmologic Center of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from January, 2017 to May, 2019. A simple random sampling was carried out; patients were distributed in 2 groups: one of control with 28 members, that received the habitual pharmacological treatment and a study group with 44 members who received systemic antibiotic therapy besides the above-mentioned. Results: Male patients prevailed, aged between 45 and 54 years (29.5 %); 72.7 % didn't show personal history of interest and the ocular trauma happened with more frequency in a rural atmosphere (77.8 %). The area 1 was the most affected (65.3 %); in 39.3 % of the patients the clínical course of trauma was less than 6 hours, but in the group that didn't receive the early systemic therapy and presented endophthalmitis (10,7 %) this time was higher, the repair happened belatedly. Conclusions: The early systemic antibiotic therapy was effective in most of the patients that received this treatment against the postraumatic endophthalmitis.

Characterization and distribution of viridans group streptococci isolated from infectious endophthalmitis and keratitis / Caracterização e distribuição de estreptococos do grupo viridans isolados de endoftalmite infecciosa e ceratite

ABSTRACT Purpose: The aims of this study were to characterize alpha-hemolytic streptococci among isolates from cases of infectious endophthalmitis and keratitis and to determine their distributions. Methods: The sample included 27 and 35 nonduplicated isolates of alpha-hemolytic streptococci recovered from patients with infectious endophthalmitis (2002-2013) and keratitis (2008-2013), respectively. Isolates were identified by the optochin susceptibility and bile solubility tests, using a biochemical identification system. The minimum inhibitory concentration was determined by the broth microdilution method. Molecular identification was performed by analyses of three constitutive genes and the complementary multilocus sequence. The molecular epidemiology of Streptococcus pneumoniae was investigated using multilocus sequence typing, and the presence of the capsular polysaccharide-encoding gene was assessed using conventional polymerase chain reaction. Outcomes were evaluated using the patients' medical records. Results: Phenotypic tests differentiated S. pneumoniae from other alpha-hemolytic streptococci, consistent with later molecular identifications. Streptococcus oralis was significantly prevalent among the endophthalmitis isolates, as was S. pneumoniae in the keratitis isolates. High levels of susceptibility to antibiotics were observed, including vancomycin, cephalosporins, and fluoroquinolones. High genetic variability was detected among the 19 S. pneumoniae strains, with 15 predicted to be encapsulated. The medical records of patients with infectious endophthalmitis were reviewed (n=15/27; 56%), and final visual acuity was assessed in 12 cases (44%). Many patients progressed to a final visual acuity state of "no light perception" (6/12; 50%), "light perception" (3/12; 25%), or "hand motion" (1/12; 8%). The medical records of patients with infectious keratitis were also reviewed (n=24/35; 69%), and final visual acuity was assessed in 18 cases (51%). Similarly, most patients progressed to a final visual acuity state of "no light perception" (6/18; 33%), "light perception" (1/18; 6%), or "hand motion" (6/18; 33%). Overall, the majority of patients progressed to a final visual acuity state of "no light perception" (12/30), "light perception" (4/30), or "hand motion" (7/30). Conclusions: The distribution of alpha-hemolytic streptococci in ocular infections suggested the presence of a species-specific tissue tropism. The prognoses of patients with ocular streptococcal infections were highly unfavorable, and antibiotic resistance did not contribute to the unfavorable clinical progressions and poor outcomes.

RESUMO Objetivo: O objetivo deste estudo foi caracterizar os estreptococos alfa-hemolíticos isolados de endoftalmite infecciosa e ceratite e determinar sua distribuição. Métodos: A amostra incluiu 27 e 35 isolados não-duplicados de estreptococos alfa-hemolíticos recuperados de pacientes com endoftalmite infecciosa (2002-2013) e ceratite (2008-2013), respectivamente. Os isolados foram identificados pelos testes de suscetibilidade à optoquina e bile solubilidade, utilizando um sistema de identificação bioquímica. A concentração inibitória mínima foi determinada pelo método de microdiluição em caldo. A identificação molecular foi realizada pela análise de três genes constitutivos e análise complementar de sequências multilocus. A epidemiologia molecular do Streptococcus pneumoniae foi investigada por tipagem de sequência multilocus, e a presença do gene codificador do polissacarídeo capsular foi avaliada por reação em cadeia da polymerase convencional. Os resultados foram avaliados utilizando os prontuários médicos dos pacientes. Resultados: Os testes fenotípicos diferenciaram S. pneumoniae dos outros estreptococos alpha-hemolíticos, consistentes com identificações moleculares posteriores. S. oralis foi significativamente prevalente entre os isolados de endoftalmite, assim como S. pneumoniae nos isolados de ceratite. Foram observados altos níveis de suscetibilidade a antibióticos, incluindo vancomicina, cefalosporinas e fluoroquinolonas. Alta variabilidade genética foi detectada entre as 19 cepas de S. pneumoniae, com 15 previstas para serem encapsuladas. Os prontuários médicos dos pacientes com endoftalmite infecciosa foram revisados (n=15/27; 56%), e a acuidade visual final foi avaliada em 12 casos (44%). Muitos pacientes evoluiram para um estado final de acuidade visual de "sem percepção luminosa" (6/12; 50%), "percepção luminosa" (3/12; 25%) ou "movimentos de mãos" (1/12; 8%). Também foram revisados os prontuários médicos dos pacientes com ceratite infecciosa (n=24/35; 69%), e a acuidade visual final foi avaliada em 18 casos (51%). Da mesma foram, a maioria dos pacientes evoluiu para um estado final de acuidade visual de "sem percepção luminosa" (6/18; 33%), "percepção luminosa" (1/18; 6%) ou "movimentos de mãos" (6/18; 33%). No geral, a maioria dos pacientes evoluiu para um estado final de acuidade visual de "sem percepção luminosa" (12/30), "percepção luminosa" (4/30) ou "movimentos de mãos" (7/30). Conclusões: A distribuição de estreptococos alfa-hemolíticos nas infecções oculares sugeriu a presença de um tropismo de tecido específico da espécie. Os prognósticos dos pacientes com infeções oculares por estreptococos foram altamente desfavoráveis e a resistência a antibióticos contribuiu não para as progressões clínicas des­favoráveis e os maus resultados.

Endogenous endophthalmitis due to Kingella Kingae infectious endocarditis / Endoftalmite endógena por endocardite infecciosa devido a Kingella Kingae

Abstract This report presents a rare case of endogenous endophthalmitis due to Kingella kingae infectious endocarditis. Endogenous endophthalmitis is a rare condition that has a systemic underlying cause, with hematogenic dissemination of a pathogen that will eventually reach and infect the eye. In this article, we present a case of a 54-year-old woman with fever, chills and decreased visual acuity and pain in the right eye. The slit-lamp exam showed conjunctival injection, anterior chamber reaction with a great amount of fibrinous material obscuring her visual axis. Ultrasound echography revealed profuse exudates and scarce membranous formation in the posterior segment. Blood culture was positive for Kingella kingae, and the patient was treated with intravenous ceftriaxone, along with topic dexamethasone and mydriatic. After 15 days of intravenous antibiotic therapy, the patient exhibited best visual acuity of 20/60. Endogenous endophthalmitis is an ocular emergency that demands quick diagnosis and aggressive intervention in order to preserve vision. Therefore, it is important to recognize its signs and symptoms with no retard.

Resumo O presente relato apresenta um raro caso de endoftalmite endógena por endocardite devido à Kingella kingae. Endoftalmite endógena é uma doença pouco comum com uma causa sistêmica subjacente. A disseminação hematogênica de um microrganismo infeccioso leva à infecção ocular. Nesse artigo, apresentamos o caso de uma mulher com 54 anos, febre, calafrios, baixa da acuidade visual e dor em olho direito. Ao exame na lâmpada de fenda apresentava injeção conjuntival, reação de câmara anterior e acúmulo de fibrina no eixo visual. Ultrassonografia revelou exsudatos profusos e escassa formação membranosa em segmento posterior.A hemocultura foi positiva para Kingella kingae e a paciente foi tratada com ceftriaxone venoso conjuntamente com dexametasona e midriático tópicos. Após 15 dias de terapia antibiótica endovenosa, a paciente apresentou acuidade visual corrigida de 20/60. Endoftalmite endógena é uma emergência ocular que demanda rápido diagnóstico e intervenção agressiva para preservar a visão. Portanto, é importante o reconhecimento precoce dos sinais e sintomas.

Endoftalmite fúngica bilateral endógena / Bilateral endogenous fungal endophthalmitis

Resumo É apresentado o caso de uma paciente do sexo feminino, 77 anos, internada por pielonefrite e tratada com antibóticos de amplo espectro, tendo desenvolvido endoftalmite endógena bilateral presumida por Candida. Foi submetida à vitrectomia via pars plana e injeção intravítrea de anfotericina B, além de voriconazol oral. São abordados, ainda, os aspectos clínicos da endoftalmite endógena por meio de revisão da literatura.

Abstract A 77 year-old female patient suffering from pyelonephritis developed bilateral endogenous endophthalmitis presumed by Candida after have been treated with global spectrum antibiotics. Early vitrectomy and intravitreal amphotericin B injection were performed, in addition to oral voriconazole. Clinical aspects of endogenous endophthalmitis are also pointed out by a literature review.

Successful treatment of fungal endophthalmitis using intravitreal caspofungin / O primeiro relato de caspofungina intravítrea no tratamento de endoftalmite fúngica

ABSTRACT Fungal endophthalmitis is a rare condition often associated with poor prognosis. We present a case of postoperative acute fungal endophthalmitis caused by the yeast-like fungus Stephanoascus ciferrii (Candida ciferrii). The fungus was resistant to fluconazole, voriconazole, and amphotericin B but susceptible to caspofungin. Because the degree of vitreal penetration of caspofungin after its intravenous administration is unclear, we performed multiple intravitreal injections, first with 50 µg/0.1 ml and then with 250 µg/0.1 ml caspofungin. Despite the recurrence of symptoms, intravitreal injection of caspofungin finally abolished the inflammation and achieved ambulatory vision that persisted until 1 year of follow-up. To our knowledge, this is the first report of S. ciferrii endophthalmitis and its successful treatment with intravitreal caspofungin.

RESUMO Endoftalmite fúngica é uma ocorrência rara, muitas vezes associada com mau prog nóstico. Apresentamos um caso de endoftalmite fúngica aguda pós-operatória causada por fungo de levedura incomum, Stephanoascus ciferrii (Candida ciferrii). O fungo foi resistente ao fluconazol, ao voriconazol e à anfotericina B e susceptível à caspofun gina. Dado que a penetração vítrea da caspofungina após administração intravenosa não é clara, optou-se por realizar múltiplas injecções intravítreas, primeiro de 50 µg e depois de 250 µg de caspofungina, e finalmente obteve-se a resolução da inflamação e a visão recuperada foi mantida por pelo menos um ano após o ocorrido. No nosso conhecimento, este é o primeiro relato de endoftalmite por Stephanoascus ciferrii e o primeiro relato de endoftalmite fúngica tratada com sucesso com caspofungina intravítrea.

Endoftalmitis posvitrectomía por Pseudomona aeruginosa / Post-vitrectomy endophthalmitis caused by Pseudomona aeruginosa

Se describe el caso de un paciente varón de 22 años, miope, sometido a vitrectomía pars plana 23 G en ojo único (valioso), por desprendimiento de retina regmatógeno. A las 24 horas presentó pérdida de visión, dolor, signos inflamatorios en globo y anejos oculares. Acudió al Servicio de Emergencias, donde se decidió su ingreso hospitalario para la toma de muestra y la aplicación de inyección intravítrea de vancomicina (1 mg/0,1 mL) y ceftazidima (2 mg/0,1 mL), con lo que mostró mejoría clínica. El estudio microbiológico reportó Pseudomona aeruginosa sensible a la ceftazidima y a la ciprofloxacina. La mejor visualización fundoscópica al quinto día posintravítrea permitió observar depósitos blanquecinos en la interfaz aceite de silicona-retina, y se decidió la extracción de aceite por incisiones mixtas 23 g y 20 g (infusión, endoiluminación y extracción respectivamente), lavado de cámara anterior, cámara vítrea, reposición de aceite de silicón y segunda dosis de ceftazidima, con evolución posoperatoria favorable. Se dio el alta una semana después, con la retina aplicada y una mejor visión corregida de 0,1(AU)

This is the report about a male 22 years-old myopic patient who underwent a pars plana 23 G vitrectomy in one eye (valuable) due to regmatogen retinal detachment. Twenty four hours after the surgery, he presented with vision loss, pain, eye bulb inflammation and ocular adnexa. He went to the emergency service where it was decided to admitted him to the hospital for sample taking and application of intravitreal injection of vancomycin (1 mg/0,1 mL) and ceftazidime (2 mg/0,1 mL) which brought about clinical improvement. The microbiological test reported the presence of ceftazidime and ciprofloxacine-susceptible Pseudomona aeruginosa. The fundus oculi performed five days after vitrectomy allowed observing whitish deports in the silicon oil/retina interface, so it was decided to remove the oil by making mixed incisions of 23 and 20 g (infusion, endoilumination and extraction, respectively), washing the anterior chamber, the vitreal chamber, returning the silicon oil and a second dosage of ceftazidime, all of which caused favorable postoperative progress. One week later, he was discharged from the hospital with replaced retina and better corrected vision of 0.1(AU)

Endoftalmite fúngica endógena bilateral secundária a pielonefrite obstrutiva / Bilateral endogenous fungal endophthalmitis secondary obstructive pyelonephritis

RESUMO Os autores relatam um caso de endoftalmite fúngica endógena bilateral ocorrida após nefrostomia descompressiva decorrente de pielonefrite obstrutiva secundária a nefrolitíase tratada, inicialmente, com injeção intravítrea de voriconazol (100 ìg/0.1 ml) porém evoluiu sem resposta terapêutica sendo necessária a vitrectomia posterior (23G).

ABSTRACT The authors report a case of bilateral endogenous fungal endophthalmitis occurred after decompression nephrostomy due to secondary obstructive pyelonephritis the treated nephrolithiasis initially with intravitreal voriconazole (100 mg / 0.1 ml) but evolved without therapeutic response requiring the posterior vitrectomy (23G).

Toxic anterior segment syndrome following deep anterior lamellar keratoplasty / Síndrome tóxica do segmento anterior após transplante lamelar anterior profundo

ABSTRACT We present the case of a 31-year-old patient with toxic anterior segment syndrome (TASS) that developed after undergoing deep anterior lamellar keratoplasty (DALK). She had keratoconus, and despite wearing hard contact lenses for many years in the left eye, her vision had deteriorated; therefore, DALK was performed on this eye. The preoperative visual acuity (VA) was finger counting at 3 m. Routine DALK was performed using the "big-bubble" technique. The corneal entry incision was hydrated at the end of the surgery, which was terminated by air injection into the anterior chamber. On postoperative day 1, VA was at the level of hand movements, and the cornea was edematous. Topical high-dose dexamethasone and oral steroids were initiated considering the diagnosis of TASS. Subsequently, the patient's VA increased, and the corneal edema decreased. We believe that the use of re-sterilized cannulas may have been the likely cause of TASS. Although DALK can be performed without interfering with the anterior chamber, one should keep in mind that TASS may occur in response to the solution used to hydrate the incision site and the air injected into the anterior chamber.

RESUMO Apresentamos o relato de uma paciente com 31 anos de idade, que desenvolveu síndrome tóxica do segmento anterior (TASS) após o procedimento de transplante lamelar anterior profundo (DALK). Ela apresentava ceratocone e, apesar de ter usado lentes de contato rígidas por muitos anos no olho esquerdo, apresentou deterioração da visão nesse olho que foi submetido a procedimento DALK. A acuidade visual (VA) era de conta dedos a três metros. O procedimento DALK de rotina foi realizado utilizando técnica de bolha grande (Big Bubble). A incisão de entrada da córnea foi hidratada ao final da cirurgia que foi terminada com a injeção de ar na câmara anterior. No primeiro dia de pós-operatório a VA era de percepção de movimentos da mão e a córnea estava edemaciada. Dexametasona tópica em alta dose e esteróides orais foram iniciadas ao se considerar o diagnóstico de TASS. Acreditamos que o uso de cânulas reesterilizadas podem ter sido a causa provável da TASS. A VA melhorou e o edema da córnea do diminuiu durante a evolução. Embora o procedimento DALK foi realizado sem interferir com câmara anterior, deve-se ter em mente que TASS pode ocorrer com a solução utilizada para hidratar o local da incisão e o ar injetado na câmara anterior.

DRESS syndrome in ophthalmic patients / Síndrome DRESS em pacientes oftalmológicos

ABSTRACT Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially fatal adverse drug reaction associated with skin rash, fever, eosinophilia, and multiple organ injury. A number of pharmacological agents are known to cause DRESS syndrome such as allopurinol, anticonvulsants, vancomycin, trimethoprime-sulfamethoxazole, and pyrimethamine-sulfadiazine. Here, we describe two patients who developed DRESS syndrome during ocular treatment. The first case was being treated for late postoperative endophthalmitis with topical antibiotics, intravenous cephalothin, meropenem, and intravitreal injection of vancomycin and ceftazidime before symptoms developed. We were unable to identify the causal drug owing to the large number of medications concurrently administered. The second case presented with DRESS syndrome symptoms during ocular toxoplasmosis treatment. In this case, a clearer association with pyrimethamine-sulfadiazine was observed. As a result of the regular prescription of pharmacological agents associated with DRESS syndrome, ophthalmologists should be aware of the potentially serious complications of DRESS syndrome.

RESUMO Síndrome DRESS (drug reaction with eosinophilia and systemic symptoms) é uma reação adversa a medicamentos rara e potencialmente fatal, associada à rash cutâneo, febre, eosinofilia e lesão de múltiplos órgãos. Algumas drogas podem desencadeá-la, como: alopurinol, anticonvulsivantes, vancomicina, sulfametoxazol-trimetoprim, sulfadiazina-pirimetamina, entre outras. Descrevemos dois casos que desenvolverem DRESS síndrome durante tratamento ocular. O primeiro caso apresentou os sintomas durante tratamento para endoftalmite pós-operatória tardia com antibióticos tópicos, cefalotina e meropenem intravenosos e injeção intravítrea de vancomicina e ceftazidima; não podemos identificar a droga causadora, pois múltiplas medicações foram utilizadas. O segundo caso desenvolveu os sintomas durante tratamento clássico para toxoplasmose ocular, então a associação com sulfadiazina-pirimetamina foi mais clara. Como muitos oftalmologistas prescrevem regularmente drogas que podem desencadear a síndrome DRESS, esse diagnóstico deve ser lembrado já que pode levar a sérias complicações.

Sucessfull management of bilateral presumed Candida endogenous endophtalmitis following pancreatitis / Tratamento bem sucedido de caso de endoftalmite endógena bilateral presumida por Candida pós pancreatite

ABSTRACT Endogenous endophthalmitis is a rare, and frequently devastating, ophthalmic disease. It occurs mostly in immunocompromised patients, or those with diabetes mellitus, cancer or intravenous drugs users. Candida infection is the most common cause of endogenous endophthalmitis. Ocular candidiasis develops within days to weeks of fungemia. The association of treatment for pancreatitis with endophthalmitis is unusual. Treatment with broad-spectrum antibiotics and total parenteral nutrition may explain endogenous endophthalmitis. We report the case of a patient with pancreatitis treated with broad-spectrum antibiotics and total parenteral nutrition who developed bilateral presumed Candida endogenous endophthalmitis that was successfully treated with vitrectomy and intravitreal amphotericin B.

RESUMO Endoftalmite endógena é uma condição oftalmológica rara e frequentemente devastadora. Ocorre principalmente em pacientes imunocomprometidos, diabéticos, com neoplasias ou usuários de drogas intravenosas. Infecção por Candida é a causa mais comum de endoftalmite endógena. A candidíase ocular ocorre de dias a semanas após a fungemia. A associação de endoftalmite e o tratamento para pancreatite é rara. O tratamento com antibióticos de amplo espectro e alimentação parenteral total podem explicar uma endoftalmite endógena. Neste estudo, reportamos o caso de um paciente com pancreatite tratado com antibióticos de amplo espectro e alimentação parenteral total que desenvolveu endoftalmite endógena bilateral presumida por Candida que foi tratado com sucesso com vitrectomia e injeção intravítrea de amfotericina B.

Postoperative fungal endophthalmitis caused by Trichosporon asahii treated with voriconazole / Endoftalmite fúngica pós-operatória causada por Trichosporon asahii tratada com voriconazol

ABSTRACTPostoperative fungal endophthalmitis is a rare but devastating complication of cataract surgery. Vitrectomy and intravitreal amphotericin B injection as well as administration of systemic antifungal agents have been suggested as optimal treatments for fungal endophthalmitis. However, this therapy may fail to eliminate fungal species resistant to current antifungal agents. The saprophytic fungus Trichosporon asahii is frequently observed as a cause of endogenous endophthalmitis in immunosuppressed patients. We report a case of postoperative endophthalmitis caused by T. asahii, resistant to amphotericin B. To the best of our knowledge, this is the first report of T. asahii endophthalmitis successfully treated with intravitreal and systemic voriconazole, pars plana vitrectomy, and removal of the intraocular lens and entire lens capsule.

RESUMOEndoftalmite fúngica pós-operatória é uma complicação rara mas devastadora da cirurgia de catarata. A vitrectomia e injeção intravítrea de anfotericina B, bem como agentes fungicidas sistêmicos, têm sido sugeridos como tratamentos ideais para endoftalmite fúngica. No entanto, esta terapia pode falhar em erradicar as espécies de fungos resistentes aos agentes antifúngicos atuais. Uma dessas espécies de fungos é o fungo saprófita,Trichosporon asahii, que é frequentemente observada, como causa de endoftalmite endógena, em pacientes imunodeprimidos. Relatamos um caso de endoftalmite pós-operatória causada porT. asahii que é resistente a anfotericina B. Ao nosso conhecimento, este é o primeiro relato de endoftalmite porT. asahii tratado com sucesso com voriconazol intravítreo e sistêmico, vitrectomia viapars plana, e remoção da lente intraocular e saco capsular.

Recent Clinical Manifestation and Prognosis of Fungal Endophthalmitis: A 7-Year Experience at a Tertiary Referral Center in Korea

This study analyzed the recent causes, prognosis, and treatment strategies for fungal endophthalmitis. A retrospective review of patients who were diagnosed with fungal endophthalmitis at our center was conducted. The fungal organisms isolated from each patient and the visual prognosis according to the route of infection and treatment method were analyzed. A total of 40 eyes from 30 patients with fungal endophthalmitis were included in this study. Candida species were the most common causative organisms in 35 of 40 eyes. Endogenous and exogenous endophthalmitis were observed in 33 and 7 eyes, respectively. Pre- and post-treatment best-corrected visual acuity (BCVA) was not significantly different between endogenous endophthalmitis and exogenous endophthalmitis. The 40 eyes were treated using the following modalities: intravitreal antifungal agent injection with intravenous antifungal agent (16 eyes), vitrectomy with intravenous antifungal agent (14 eyes), intravenous antifungal agent alone (9 eyes), and evisceration (1 eye). Post-treatment BCVA only significantly improved after treatment in the vitrectomy group. Candida species were the most common cause of fungal endophthalmitis, irrespective of the route of infection. The visual prognosis of fungal endophthalmitis was generally poor. In conclusion, if the general condition of the patient tolerates a surgical procedure, prompt vitrectomy and intravitreal injection of antifungal agents can improve visual acuity.

Del total de bacterias Gram positivas, 1,1 %, 0 %, 1,1 %, 16,9 %, 29,3 % y 85 % fue resistente a imipenem, moxifloxacina, gatifloxacina, levofloxacina, ciprofloxacina y tobramicina, respectivamente, mientras que la resistencia a estos mismos fármacos se presentó, respectivamente, en 0 %, 8,3 %, 0 %, 0 %, 18,2 % y 27,3 % de las bacterias Gram negativas. Los porcentajes de resistencia de los estafilococos positivos para coagulasa resistentes a la meticilina fueron 0 %, 0 %, 0 %, 7 %, 17 % y 100 %, respectivamente, y los porcentajes de los estafilococos negativos para coagulasa resistentes a la meticilina fueron 3 %, 0 %, 0 %, 24 %, 44 % y 100 %, respectivamente. Los porcentajes de resistencia bacteriana globales (tanto para bacterias Gram positivas como para Gram negativas) a imipenem, moxifloxacina, gatifloxacina, levofloxacina, ciprofloxacina y tobramicina fueron 1 %, 1 %, 1 %, 15,1 %, 28 % y 64,5 %, respectivamente. Conclusiones. Los niveles de resistencia bacteriana para imipenem, moxifloxacina y gatifloxacina fueron menores que para levofloxacina, ciprofloxacina y tobramicina. Los niveles de resistencia para la tobramicina fueron muy altos, lo que pone en duda su utilidad clínica en las infecciones oculares en nuestro medio.

Introduction: Bacterial resistance is critical for the selection of antibiotics in the treatment of infections, so it is vital to know its current status in our geographical area. Objective: To determine in vitro antibiotic susceptibility of bacterial isolates obtained from keratitis and intraocular infections. Materials and methods: A retrospective study of microbiological tests in Fundación Oftalmológica de Santander (FOSCAL) was carried out between June, 2011, and January, 2012. Results: A total of 92 samples were examined and 110 bacteria, 27 fungi and 12 free-living amoebae were identified. Polymicrobial infections constituted 50% of the total; 1.1%, 0%, 1.1%, 16.9%, 29.3% and 85% of Gram-positive bacteria were resistant to imipenem, moxifloxacin, gatifloxacin, levofloxacin, ciprofloxacin and tobramycin, respectively, while 0%, 8.3%, 0%, 0%, 18.2% and 27.3% of Gram-negative bacteria were resistant to imipenem, moxifloxacin, gatifloxacin, levofloxacin, ciprofloxacin and tobramycin, respectively. For methicillin-resistant coagulase-positive staphylococci, resistance percentages to imipenem, moxifloxacin, gatifloxacin, levofloxacin, ciprofloxacin and tobramycin were 0%, 0%, 0%, 7%, 17% and 100%, respectively. For methicillin-resistant coagulase-negative staphylococci, resistance percentages to imipenem, moxifloxacin, gatifloxacin, levofloxacin, ciprofloxacin and tobramycin were 3%, 0%, 0%, 24%, 44% and 100%, respectively. Overall bacterial resistance to imipenem, moxifloxacin, gatifloxacin, levofloxacin, ciprofloxacin and tobramycin, for both Gram-positive and Gram-negative, was 1%, 1%, 1%, 15.1%, 28% and 64.5%, respectively. Conclusions: The levels of bacterial resistance to imipenem, moxifloxacin and gatifloxacin were lower than for levofloxacin, ciprofloxacin and tobramycin. The levels of resistance to tobramycin were very high, which calls into question its usefulness in this region of our country.

Endoftalmitis endógenas: revisión de una serie de casos y revaloración de una entidad ocular grave / Endogenous endophthalmitis: case report and brief review of a serious ocular disease

Endogenous endophthalmitis (EE) is a prevalent but serious disease. Our aim was to describe cases of EE, with emphasis in the risk factors and the improvement of the prognosis. Methods: A review of EE cases was done between 1996-2011 in a secondary care hospital in Spain. The reported variables were: comorbidities, isolated microorganisms, susceptibility to antimicrobial treatment and visual prognosis. Results: 9 cases of EE were analyzed. All had some underlying disease, diabetes mellitus being the most frequent. Seven of the nine cases had a history of eye injury. Extraocular source of infection was identified in 7 cases, with predominantly gastrointestinal disease. Most microorganisms were isolated from blood cultures. The visual prognosis was unfavorable in five patients and was associated with virulent microorganisms and delayed treatment. Conclusions: EE is a rare disease that involve immunocompromised patients with ophthalmic disease. To improve prognosis, appropriate diagnosis and early treatment is require. Therefore, we recommend funduscopy examination in patients with sepsis, risk factors and prior history of ocular disease.

La endoftalmitis endógena (EE) es una patología poco prevalente aunque grave. Nuestro objetivo es describir los casos de EE diagnosticados en un hospital secundario español, con particular atención a los factores de riesgo y la posible mejora del pronóstico. Material y Métodos: Revisamos las historias clínicas de los pacientes diagnosticados de EE entre 1996-2011. Las variables recogidas fueron: co-morbilidades, microorganismo/s aislados y su susceptibilidad a los antimicrobianos, tratamiento administrado y pronóstico visual. Resultados: Se estudiaron nueve casos de EE. Todos presentaban alguna enfermedad de base, siendo diabetes mellitus la más frecuente. Siete de los nueve casos presentaron antecedentes de lesión ocular. La probable fuente extraocular se identificó en siete casos, predominando el foco gastrointestinal. La mayoría de microorganismos se aisló de hemocultivos. El pronóstico visual fue desfavorable en cinco pacientes, asociándose a microorganismos virulentos y al retraso terapéutico. Conclusiones: La EE es una enfermedad inusual que afecta a pacientes con inmunidad disminuida y antecedentes oftalmológicos. Para mejorar el pronóstico se requiere un diagnóstico acertado y un tratamiento precoz, todo un reto para médicos clínicos y microbiólogos. Por ello, recomendamos realizar un fondo de ojo a los pacientes con sepsis, factores de riesgo de EE y antecedentes de patología ocular.

Management of post-operative Nocardia endophthalmitis.

Post-operative Nocardia endophthalmitis has an aggressive course and poor visual prognosis. It often masquerades as severe post-operative uveitis or toxic anterior segment syndrome due to the absence of vitreous involvement resulting in a delay in diagnosis. The poor prognosis in Nocardia endophthalmitis is due to severe intra-ocular inflammation which may lead to phthisis. Therefore, treatment with corticosteroids after appropriate antibiotics have been initiated may improve the outcome. This is an interventional case report highlighting the typical features of Nocardia endophthalmitis, which when diagnosed early and managed medically with antibiotics and steroids, resulted in an excellent visual outcome in our patient.
