RESUMO

Cuando se produce una erosión corneal y fracasa la epitelización corneal surgen los defectos epiteliales corneales persistentes, cuyo tratamiento es un desafío para el oftalmólogo. Es muy frecuente el fracaso del tratamiento convencional por lo que se mantiene el interés en la búsqueda de otros factores de crecimiento para la cicatrización epitelial tales como los colirios de insulina. La insulina es un péptido estrechamente relacionado con el factor de crecimiento similar a la insulina 1. Su mecanismo de acción no es bien comprendido, sin embargo se acepta que es capaz de inducir migración y proliferación de las células epiteliales corneales, por lo que promueve y acelera la reepitelización de defectos epiteliales persistentes refractarios a tratamiento. La ausencia de una presentación comercial de colirio de insulina, hace necesario conocer su estabilidad físicoquímica y microbiológica así como la eficacia, efectividad y seguridad del colirio de insulina a diferentes concentraciones. De ahí la motivación para realizar una revisión de la literatura existente sobre el empleo del colirio de insulina en el tratamiento del defecto epitelial corneal persistente. Se realizó la búsqueda en bases de datos electrónicas como PubMed Central, EBSCO, Clinical Trials.gov, MEDLINE OVID, EMBASE OVID con el objeto de identificar artículos relacionados con el tema(AU)


When corneal erosion occurs and corneal epithelialization fails, persistent corneal epithelial defects arise, whose treatment is a challenge for the ophthalmologist. The failure of conventional treatment is very frequent; therefore, there is still interest in the search for other growth factors for epithelial healing, such as insulin eye drops. Insulin is a peptide closely related to insulin-like growth factor 1. Its mechanism of action is not well understood; however, it is accepted that it is capable of inducing migration and proliferation of corneal epithelial cells, thereby promoting and accelerating reepithelialization of persistent epithelial defects refractory to treatment. The absence of a commercial presentation for insulin eye drops makes it necessary to know its physicochemical and microbiological stability, as well as the efficacy, effectiveness and safety of insulin eye drops at different concentrations; hence the motivation to review the existing literature on the use of insulin eye drops in the treatment of persistent corneal epithelial defects. The search was carried out in electronic databases such as PubMed Central, EBSCO, Clinical Trials.gov, MEDLINE OVID, EMBASE OVID, with the aim of identifying relevant articles related to the topic(AU)

RESUMO

El propósito es identificar a través de una revisión sistemática de la literatura, la evidencia actual frente a la eficacia del tratamiento de la insulina tópica en patologías de la superficie ocular. Se implementó una búsqueda de literatura en bases de datos de indexación médica Medline (Pubmed), Embase y Web Of Science a través de palabras claves como «insulin» AND «córnea» OR «corneal» OR «dry eye» artículos publicados en inglés o español en los últimos once años (2011-2022). Se identificaron nueve artículos con 180 participantes provenientes de Estados Unidos, España, Irlanda, Canadá, Portugal y Malasia, con defectos epiteliales persistentes refractarios y secundarios a vitrectomía, cuya extensión de la lesión fue de 3,75 mm2 hasta 65,47 mm2. La preparación fue disuelta con lágrimas artificiales y la concentración de insulina fue desde 1 UI/ml hasta 100 UI/ml. En todos los casos la resolución del cuadro clínico fue completa con un tiempo de curación desde 2,5 días hasta 60,9 días siendo este último un caso secundario a una quemadura por cáusticos de difícil control. La insulina tópica ha sido efectiva para el tratamiento de defectos epiteliales persistentes; la de acción intermedia y en bajas concentraciones demostró menor tiempo de resolución, en úlceras neurotróficas y secundarias a vitrectomías (AU)


The purpose is to identify, through a systematic literature review, the current evidence regarding the effectiveness of topical insulin treatment in ocular surface pathologies. A literature search was implemented in Medline (Pubmed), Embase and Web Of Science medical indexing databases by using keywords such as “insulin” AND “cornea” OR “corneal” OR “dry eye” in published papers in English or Spanish within the last eleven years (2011-2022). Nine papers were identified with 180 participants from the United States, Spain, Ireland, Canada, Portugal and Malaysia, with persistent refractory epithelial defects and secondary to vitrectomy, whose extension of the lesion was from 3.75 mm2 to 65.47 mm2. The preparation was dissolved with artificial tears and the insulin concentration ranged from 1 IU/ml to 100 IU/ml. In all cases, the resolution of the clinical picture was complete with a healing time from 2.5 days to 60.9 days, the latter being a secondary case to a difficult-to-control caustic burn. Topical insulin has been effective for the treatment of persistent epithelial defects. The intermediate action and low concentrations showed a shorter resolution time in neurotrophic ulcers and induced during vitreoretinal surgery (AU)

RESUMO

En los últimos años, múltiples investigaciones han mostrado la participación de los factores de crecimiento en la regeneración de diferentes tejidos, lo que ha llevado a la utilización de los derivados hemáticos. Se considera este tratamiento una herramienta viable y efectiva para favorecer la epitelización en enfermedades de la superficie ocular. Es necesario encontrar una terapia eficaz en las alteraciones de la superficie ocular rebeldes a tratamientos convencionales. El objetivo del estudio es demostrar que la terapia celular es una novedosa disciplina científica a aplicar en nuestro medio. Se presentan tres casos atendidos en el servicio de córnea del Instituto Cubano de Oftalmología "Ramón Pando Ferrer" con enfermedades de la superficie ocular. Caso clínico 1, paciente con úlcera corneal bacteriana grave que evolucionó a adelgazamiento en los 360°. Caso clínico 2, paciente con diagnóstico de melting corneal post de displasia conjuntival. Caso clínico 3, paciente con defecto epitelial post úlcera corneal. En los tres casos, se indicó plasma rico en plaquetas como único tratamiento, con una duración variable según respuesta al tratamiento. En todos los casos se logró regeneración epitelial en menor tiempo y rápida mejoría de las manifestaciones clínicas. No presentaron complicaciones, los pacientes mejoraron la agudeza visual tras lograr la cicatrización corneal. Es una terapia eficaz y de fácil obtención. Tiene impacto en la calidad de vida del paciente, con rápida reincorporación laboral y social, por lo que reduce los gastos sociales y económicos por tiempo de enfermedad y recuperación(AU)


In recent years, multiple investigations have shown the participation of growth factors in the regeneration of different tissues, which has led to the use of hematic derivatives. This treatment is considered a viable and effective tool to promote epithelialization in diseases of the ocular surface. It is necessary to find an effective therapy in alterations of the ocular surface that are resistant to conventional treatments, the objective of the study being to show cell therapy as a novel scientific discipline to be applied in our environment. Three cases treated in the cornea service of the Cuban Institute of Ophthalmology "Ramón Pando Ferrer" with diseases of the ocular surface are presented. Clinical case 1, patient with severe bacterial corneal ulcer that progressed to 360° thinning. Clinical case 2, patient diagnosed with corneal melting after conjunctival dysplasia and clinical case 3, patient with epithelial defect post corneal ulcer. In all three cases, platelet-rich plasma (PRP) was indicated as the only treatment, with a variable duration depending on the response to treatment. In all cases, the following was achieved: epithelial regeneration in less time and rapid improvement of clinical manifestations, no complications, patients improved visual acuity at the end of achieving corneal healing. Is an effective and easily obtained therapy. It has an impact on the patient's quality of life, with rapid work and social reintegration, thus reducing social and economic expenses due to illness and recovery time(AU)

RESUMO

Las queratitis infecciosas (QI) son una de las causas más comunes de ceguera a nivel mundial, especialmente en países en vías de desarrollo, y puede llegar a representar del 5,1 al 32,3% de todas las indicaciones de queratoplastia penetrante. Sin embargo, realizar una queratoplastia terapéutica «en caliente» está asociado con una mayor incidencia de recurrencia de la QI y rechazo del injerto. El tratamiento estándar incluye antimicrobianos (ATM) de amplio espectro y, una vez identificado el patógeno causante y el antibiograma, continuar con un tratamiento dirigido, según la sensibilidad del germen. La aparición de cepas multirresistentes a los ATM está aumentando progresivamente a un ritmo alarmante en los últimos tiempos. Asimismo, la diversidad de los microorganismos causantes (bacterias, hongos, parásitos, virus) dificulta en ocasiones la realización de un diagnóstico clínico correcto, retrasando el inicio de un tratamiento efectivo. Se estima que solo un 50% de los ojos tendrá un buen resultado visual si se retrasa la terapia. En definitiva, todos estos factores hacen que sea muy importante la identificación de alternativas al tratamiento ATM. Por las propiedades ATM del cromóforo fotoactivado (riboflavina) y la luz ultravioleta de longitud de onda 200-400nm, utilizada en múltiples aplicaciones médicas y no médicas para la desinfección, se ha propuesto el cromóforo fotoactivado para el cross-linking corneal en el tratamiento de las QI, como una herramienta adicional en el arsenal terapéutico de las QI. Debe diferenciarse del cross-linking empleado para el manejo del queratocono progresivo. El objetivo de esta revisión es actualizar la evidencia disponible sobre la eficacia y seguridad del cromóforo fotoactivado para el cross-linking en las QI (AU)


Infectious keratitis (IK) is one of the most common causes of monocular blindness worldwide, especially in developing countries, and may account for 5.1 to 32.3% of all indications for penetrating keratoplasty (PK). However, performing a therapeutic PK on a “hot eye” is associated with a higher incidence of IK recurrence and graft rejection. Standard treatment includes antimicrobials (ATM) and, once the causative pathogen has been identified, must be continued with targeted treatment, depending on antibiogram sensitivity. However, appearance of multiresistant strains to ATM is progressively increasing at an alarming rate. Besides that, the diversity of the causative microorganisms (bacteria, fungi, parasites, viruses) may hinder the clinical diagnosis and secondarily the proper treatment from the beginning. It is estimated that only 50% of eyes will have a good visual result if the correct therapy is delayed. All these factors make the identification of alternatives to ATM treatment of paramount importance. Due to the ATM properties of photoactivated chromophore (riboflavin) and ultraviolet light of wavelength 200-400nm, used in multiple medical and non-medical applications for disinfection, photoactivated chromophore for corneal cross-linking (CXL) of IK, as an addition to the therapeutic arsenal for the management of IK has been proposed. It must be differentiated from CXL used for the management of progressive keratoconus. The objective of this review is to update the available evidence on the efficacy and safety of photoactivated chromophore for corneal CXL in IKs (AU)

RESUMO

Infectious keratitis (IK) is one of the most common causes of monocular blindness worldwide, especially in developing countries and may account for 5.1%-32.3% of all indications for penetrating keratoplasty (PK). However, performing a therapeutic PK on a "hot eye" is associated with a higher incidence of IK recurrence and graft rejection. Standard treatment includes antimicrobials (ATM) and, once the causative pathogen has been identified, must be continued with targeted treatment, depending on antibiogram sensitivity. However, appearance of multiresistant strains to ATM is progressively increasing at an alarming rate. Besides that, the diversity of the causative microorganisms (bacteria, fungi, parasites, viruses) may hinder the clinical diagnosis and secondarily the proper treatment from the beginning. It is estimated that only 50% of eyes will have a good visual result if the correct therapy is delayed. All these factors make the identification of alternatives to ATM treatment of paramount importance. Due to the ATM properties of photoactivated chromophore (riboflavin, RB) and ultraviolet (UV) light of wavelength (λ) 200-400 nanometers (nm), used in multiple medical and non-medical applications for disinfection, photoactivated chromophore for corneal cross-linking (CXL) of IK (PACK-CXL), as an addition to the therapeutic arsenal for the management of IK has been proposed. It must be differentiated from CXL used for the management of progressive keratoconus (KC). The objective of this review is to update the available evidence on the efficacy and safety of PACK-CXL in IKs.

RESUMO

Se realizó una revisión bibliográfica exhaustiva sobre la anatomía de la córnea, a fin de profundizar en los principales factores predisponentes de la úlcera corneal, sus causas, cuadro clínico, evolución, complicaciones y tratamiento. Se analizó conceptualmente la enfermedad y se propuso incluir en su concepto el método clínico como premisa. Actualmente, en la provincia de Santiago de Cuba, la curación de estas úlceras constituye un problema de salud a resolver, puesto que los tratamientos convencionales no siempre permiten una evolución estable de los pacientes diagnosticados, razón por la cual surge la necesidad de buscar medicamentos y alternativas terapéuticas para tratar a dichos pacientes.


An exhaustive literature review on the cornea anatomy was carried out in order to deepen in the main predisposing factors of the corneal ulcer, their causes, clinical picture, clinical course, complications and treatment. The disease was conceptually analyzed and it was suggested to include in its concept the clinical method as premise. At the moment, in Santiago de Cuba province, the cure of these ulcers constitutes a health problem to solve, since the conventional treatments not always allow a stable clinical course of the diagnosed patients, reason why there is a necessity of searching medicines and therapeutic alternatives to treat them.

Para la validación estadística se utilizó prueba Chi-cuadrado. Resultados: La edad promedio de los pacientes fue de 54,1 años, el 62,5 % eran hombres. Predominó el trauma ocular (63,3 %) en el sexo masculino y enfermedades oculares (44,4 %) en el femenino. La mejoría de los signos fue más representativa a los 14 días. Se logró resultados satisfactorios en el 100 % de los pacientes con microorganismos grampositivos. El 10,4 % presentó perforación corneal. Conclusiones: La ozonoterapia es una terapia válida como tratamiento en la úlcera corneal grave de etiología bacteriana y responde a la búsqueda de alternativas para pacientes con resistencia a los tratamientos antibacterianos que se ofertan en el cuadro básico de salud.


ABSTRACT Introduction: Spontaneous evolution or poorly treated cases of corneal ulcer carry the risk of extension of the infection, with severe visual impairment and damage to the structural integrity of the eye. Objective: To describe the clinical-epidemiological characteristics of patients with severe bacterial corneal ulcer treated with local ozone therapy as an adjunct to the standard protocol treatment. Method: An observational, descriptive and cross-sectional study was carried out on 48 patients admitted to the Ophthalmology service of the Hospital General Docente "Dr. Juan Bruno Zayas Alfonso", from Santiago de Cuba, in the period from January 2017 to December 2019. The study variables were: age, gender, predisposing factors, microorganisms, signs of clinical improvement, treatment results and complications. Chi-square test was used for statistical validation. Results: The average age of the patients was 54.1 years; 62.5% of them were men. Ocular trauma (63.3%) predominated in males, and ocular diseases (44.4%) in females. The improvement of the signs was more common after 14 days. Satisfactory results were achieved in 100% of patients with gram-positive organisms. 10.4% presented corneal perforation. Conclusions: Ozone therapy is valid as a treatment for severe corneal ulcer of bacterial etiology, and responds to the search for alternatives for patients with resistance to the antibacterial treatments that are offered in the basic health system.

RESUMO

Introducción: La úlcera corneal infecciosa es una afección frecuente en la consulta de oftalmología. Su resolución es un problema de salud a resolver, pues los tratamientos convencionales no siempre garantizan una evolución favorable de los casos diagnosticados debido a la resistencia microbiana, por lo que se siguen buscando alternativas terapéuticas. Objetivo: Describir las alternativas de tratamiento en la úlcera corneal infecciosa para minimizar sus secuelas y disminuir la ceguera por esta enfermedad. Desarrollo: La administración tópica de antibióticos de amplio espectro sigue siendo el método preferido para el tratamiento farmacológico de las úlceras corneales infecciosas, a pesar de los informes de fracasos clínicos por la resistencia a los antibióticos, por lo que se investiga acerca del uso de nuevas alternativas terapéuticas que minimicen las secuelas de esta enfermedad.Se realizó una revisión sistemática de la evidencia científica en los últimos diez años en diversos artículos, en los que se constató la aplicación de diferentes sustancias como tratamiento alternativo. Conclusiones: En la úlcera corneal infecciosa el tratamiento protocolizado combinado con sustancias alternativas, que tienen en común una actividad de amplio espectro, resultaría ser ventajoso por ser productos económicos y seguros, que han demostrado un gran poder bactericida. Se propone generalizar el uso de estos compuestos, dada la resistencia de los microorganismos al tratamiento convencional; lo que hace que la úlcera corneal sea un problema de salud a resolver.


Introduction: The infectious corneal ulcer is a frequent disorder in the ophthalmology outpatient department, its solution is a health problem to be solved, as the conventional treatments don't always guarantee a favorable clinical course of the diagnosed cases. Because of the microbial resistance, so that therapeutic alternatives are still looked for. Objective: To describe the treatment alternatives in the infectious corneal ulcer for minimizing their sequelae and to decrease blindness due to this disease. Development: The topical administration of wide spectrum antibiotics continues being the favorite method for the pharmacological treatment of the infectious corneal ulcers, in spite of the clinical failures reports caused by the resistance to antibiotics, that is why the use of new therapeutic alternatives minimizing the sequels of this disease is investigated. Method: A systematic review of the scientific evidence in the last ten years was carried out on several works, in which it was evidenced the use of different substances as alternative treatment. Conclusions: In the infectious corneal ulcer the protocolized treatment combined with alternative substances which have in common a wide spectrum activity would turn out to be advantageous as they are economic and sure products which have demonstrated a great power against bacteria. The use of these compounds could be generalized, given the resistance of organisms to the conventional treatment; what makes the corneal ulcer a health problem to be solved.

RESUMO

RESUMEN Introducción: Las úlceras corneales no se han caracterizado en el Hospital General Docente "Dr. Agostinho Neto" de Guantánamo. Objetivo: Caracterizar la úlcera corneal en pacientes atendidos en el Servicio de Oftalmología de este hospital en el período de enero 2014 a julio 2019. Método: Se realizó un estudio descriptivo, retrospectivo y longitudinal con 40 pacientes. Se estudiaron las variables: sexo, edad, procedencia, ocupación, factores de riesgo, etiología, tratamiento y complicaciones de este tipo de úlcera y las modificaciones de la agudeza visual de acuerdo al tratamiento que se les aplicó. Resultados: El 75,0 % de los pacientes fue del sexo masculino que tenían 65 o más años de edad (47,5 %), procedían de áreas rurales (72,5 %) y realizaban actividades agrícolas (45,0 %). El trauma corneal fue el factor de riesgo más usual (25,0 %). En el 47,5 % la úlcera fue de etiología micótica. El 100 % recibió tratamiento farmacológico, sobre todo con colirio antibiótico fortificado (25,0 %). Se le aplicó tratamiento quirúrgico al 27,5 %, la técnica más común fue el recubrimiento conjuntival (15,0 %). La agudeza visual mejoró en el 75,0 % de los pacientes luego del tratamiento. Conclusiones: En el Hospital General Docente "Dr. Agostinho Neto" la úlcera corneal no es un problema de salud, pero sí determina la agudeza visual de los pacientes afectados, en los que es más común la etiología micótica y la necesidad del uso de colirios fortificados.


ABSTRACT Introduction: Corneal ulcers have not been characterized in the General Teaching Hospital "Dr. Agostinho Neto" from Guantanamo. Objective: To characterize the corneal ulcer in patients treated in the Ophthalmology Service of this hospital in the period from January 2014 to July 2019. Method: A descriptive, retrospective and longitudinal study was carried out with 40 patients. The variables were studied: sex, age, origin, occupation, risk factors, etiology, treatment and complications of this type of ulcer and the modifications of visual acuity according to the treatment applied to them. Results: 75.0% of the patients were male who were 65 years of age or older (47.5%), came from rural areas (72.5%) and carried out agricultural activities (45.0%). Corneal trauma was the most usual risk factor (25.0%). In 47.5% the ulcer was of fungal etiology. 100% received drug treatment, especially with fortified antibiotic eye drops (25.0%). Surgical treatment was applied to 27.5%, the most common technique was the conjunctival lining (15.0%). Visual acuity improved in 75.0% of patients after treatment. Conclusions: In the General Teaching Hospital "Dr. Agostinho Neto" corneal ulcer is not a health problem, but it does determine the visual acuity of affected patients, in which the fungal etiology and the need for the use of fortified eye drops are more common.

RESUMO

RESUMEN Objetivo: Describir los factores predisponentes a la queratoplastia terapéutica en los pacientes con úlcera grave de la córnea. Métodos: Se realizó un estudio descriptivo, transversal, con una muestra de 64 pacientes que fueron operados en el Servicio de Córnea del Instituto Cubano de Oftalmología Ramón Pando Ferrer, de enero del año 2011 a diciembre de 2014. Resultados: La muestra se caracterizó según las variables sociodemográficas edad (promedio de 51,3 ± 2,9); sexo (el 67,2 por ciento correspondió al masculino); y grupos etarios de riesgo (el 83,3 por ciento fueron agricultores y el 74,6 por ciento urbanos). Los traumatismos más frecuentes fueron ocasionados por cuerpos extraños (26,6 por ciento), lentes de contacto (9,4 por ciento) y quemaduras por agentes químicos (6,3 por ciento). Los pacientes recibieron tratamiento en el 82,8 por ciento durante 22,5 ± 4,6 días previos al ingreso y 6,9 días antes de la queratoplastia. Los resultados microbiológicos revelaron un 88,2 por ciento de positividad. Los hongos filamentosos y las bacterias fueron los aislamientos más frecuentes. Conclusiones: El sexo masculino, las labores agrícolas, el tratamiento ambulatorio con un tiempo de duración previo a la queratoplastia entre 18 y 27 días y los hongos filamentosos como agente etiológico se consideran factores de riesgo a queratoplastia terapéutica en las úlceras corneales(AU)


ABSTRACT Objective: Describe the predisposing factors for therapeutic keratoplasty in patients with severe corneal ulcer. Methods: A descriptive cross-sectional study was conducted of a sample of 64 patients admitted to the Cornea Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology from January 2011 to December 2014. Results: The sample was characterized according to the following sociodemographic variables: age (mean of 51.3 ± 2.9); sex (67.2 percent were male), and risk age groups (83.3 percent were farmers and 74.6 percent were urban). The most common traumas were caused by foreign bodies (26.6 percent), contact lenses (9.4 percent) and chemical burns (6.3 percent). 82.8 percent of the patients received treatment during 22.5 ± 4.6 days before admission and 6.9 days before keratoplasty. Microbiological results revealed 88.2 percent positivity. Filamentous fungi and bacteria were the most common isolates. Conclusions: Male sex, farming, outpatient treatment for 18 to 27 days before keratoplasty and filamentous fungi as etiological agents, are considered to be risk factors for therapeutic keratoplasty in corneal ulcers(AU)

RESUMO

Se describe el caso clínico de un paciente de 72 años de edad, con diagnóstico de pénfigo vulgar, quien fue asistido en la consulta de Oftalmología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba porque padecía enrojecimiento ocular, unido a disminución de la visión y secreciones abundantes de aproximadamente 5 días de evolución. En el examen oftalmológico se confirmó la presencia de úlcera corneal bilateral por perforación infecciosa. Se indicó tratamiento con colirios de antibióticos (ceftazidima y amikacina), antiinflamatorio no esteroideo, agentes antihipertensivos y lente de contacto, con lo cual mejoraron las lesiones de ambos ojos. El proceso infeccioso pudo deberse a cierta susceptibilidad a los esteroides e inmunosupresores sistémicos, como terapia asociada al pénfigo vulgar, o al mecanismo autoinmune característico de esta dermatopatía.


The case report of a 72 years patient is described, with diagnosis of pemphigus vulgaris who went to the Ophthalmology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba because he suffered from ocular redness, together with a decrease vision and abundant secretions of approximately 5 days of history. In the ophthalmological examination the presence of bilateral corneal ulcer was confirmed due to infectious perforation. Treatment was indicated with antibiotic eyewashes (ceftazidime and amikacine), non esteroidal anti-inflammatory drugs, antihypertensive agents and contact lens, with which the injuries of both eyes improved. The infectious process could be due to certain susceptibility to the steroids and systemic inmunosupressors, as therapy associated with pemphigus vulgaris, or to the autoinmune mechanism characterizing this dermatopathy.

RESUMO

BACKGROUND: Dematiaceous fungal genus Curvularia is a causal agent of keratitis, onychomycosis, and skin infections. In 2014, using DNA sequencing techniques, five new species, including Curvularia hominis, were described. In this article, a report is presented on the first clinical case of C.hominis infection in Spain. It concerns a corneal ulcer caused by this recently described species. CASE REPORT: A 46 year-old male patient with a corneal ulcer in his left eye went to the Emergency Department. Specimens were obtained from the lesion, and the patient was admitted due to the risk of corneal perforation. The fungal culture of the specimens revealed a filamentous fungus that was identified by microscopic examination as Curvulariaspp. Using mass spectrometry (MALDI-TOF) the isolate was identified as Curvularia lunata. To confirm the identification, the isolate was sent to the National Centre of Microbiology in Spain, where ITS region sequencing was performed, and it was finally identified as C.hominis. The patient received voriconazole and progressed favourably. To repair the corneal damage, the patient received an amniotic membrane transplantation. CONCLUSIONS: C.hominis should be considered a causal agent of keratitis and sequencing techniques are now necessary for species-level identification of Curvularia isolates. This is the first case report in Spain caused by this species.

RESUMO

CLINICAL CASE: A 51 year-old immunocompetent male was referred due to presenting with a large corneal ulcer with hypopyon in the right eye. Topical amphotericin B, fluconazole and moxifloxacin, as well as oral itraconazole were initially indicated. Following the report of mycotic structures on staining, topical natamycin was started. The result of the culture was reported two weeks later as, Scedosporium apiospermum (S. apiospermum), and topical voriconazole was then added. The response to treatment was very slow, and took five weeks after receiving triple therapy (natamycin, voriconazole and fluconazole) and one dose of intrastromal voriconazole, for the hypopyon to disappear. The final outcome was successful, achieving healing of the ulcer. The patient is waiting for a corneal transplant. DISCUSSION: A microbiological study is essential in patients in whom fungal keratitis is suspected. The treatment of choice against S. apiospermum is with voriconazole, but the combination of various antifungal agents may be required.

RESUMO

Introducción: la úlcera corneal es una inflamación supurada que puede tener múltiples etiologías y manifestaciones clínicas. Es una entidad potencialmente grave que amenaza la visión del paciente y puede causar ceguera. Objetivos: describir los fundamentos teóricos que sustentan el uso de los colirios fortificados en el tratamiento de la úlcera grave de la córnea, identificar las variables clínico epidemiológicas del grupo de estudio, establecer el diagnóstico clínico y etiológico de la úlcera corneal y evaluar la evolución de la enfermedad y la incidencia de complicaciones. Materiales y métodos: se realizó una investigación descriptiva, transversal, en el período entre enero del 2015 y enero del 2016. Se tuvo en consideración los pacientes con diagnóstico de úlcera grave de la córnea que ingresaron en el centro hospitalario .La muestra estuvo conformada por 23 pacientes con diagnóstico de úlcera grave de la córnea. Resultados: de los 23 pacientes diagnosticados la úlcera grave de la córnea predominó en el sexo masculino y mayores de 60 años de edad. Predominó la etiología bacteriana y la úlcera central profunda. Dentro de los factores de riesgo ocular los resultados señalan como principal factor el trauma ocular (56,5%), el uso de antibiótico tópico y sistémico por tiempo prolongado. Todos los pacientes recibieron tratamiento tópico con colirio fortificado, entre las complicaciones se presentó el descematocele en un 30,4 % de los casos. Conclusiones: La fundamentación teórica de los colirios fortificados y los resultados obtenidos en esta investigación, demuestran la eficacia del uso en la úlcera grave de la córnea (AU).


Introduction: the corneal ulcer is a suppurated inflammation that may have several etiologies and clinical manifestations. It is a potentially serious entity endangering the patient´s vision and could cause blindness. Objective: to describe the theoretical fundaments supporting the use of fortified eye drops in the treatment of severe corneal ulcer; to identify the clinic-epidemiological variables of the studied group; to arrive to the clinical and etiological diagnosis of the corneal ulcer and to assess disease evolution and complications incidence. Materials and methods: a descriptive, cross-sectional research was carried out in the period from January 2015 to January 2016. The patients diagnosed with severe corneal ulcer who were admitted in the hospital were taken into consideration. The sample was formed by 23 patients diagnosed with severe corneal ulcer. Results: among the 23 patients diagnosed with severe corneal ulcer predominated male sex and people aged more than 60 years. The bacterial etiology and deep central ulcer predominated. As for the ocular risk factors, the results show ocular trauma as main factor (56.5 %) and the use of systemic and topical antibiotic for a long time. All the patients were topically treated with fortified eye drops. Descematocele was found among the complications in 30.4 % of the cases. Conclusions: the theoretical fundament of the fortified eye drops and the results obtained in this research show the efficacy of their use in the severe corneal ulcer (AU).

RESUMO

La queratitis por herpes simple es una de las causas más importantes de ceguera por infección corneal. El virus permanece latente en el huésped humano después de la infección primaria y puede ser reactivado por muchos factores, como traumatismos, estrés, exposición al sol, procesos que cursen con fiebre asociada, procedimientos quirúrgicos, entre otros. Una vez activado, se traslada a través del nervio trigémino hacia la córnea y causa la infección recurrente, la cual produce cicatrización corneal. Clínicamente, la membrana amniótica usada como sustituto de la membrana basal ha sido aplicada satisfactoriamente para el manejo de defectos epiteliales persistentes con o sin ulceración. Además, se ha descrito que el trasplante de membrana amniótica de múltiples capas es útil para el tratamiento de úlceras corneales profundas, descemetoceles y perforaciones corneales pequeñas. El presente reporte describe un caso de queratitis por herpes simple tratado con membrana amniótica con el que se obtuvo una agudeza visual buena y ausencia de queratitis recurrente durante dos años


Herpes simplex keratitis is one of the leading causes of infectious corneal blindness in the world. It remains latent in the human host after the primary infection and can be reactivated by many factors. When activated, it travels along the trigeminal nerve to the cornea, and causes recurrent infection which leads to corneal scarring. Clinically, preserved AM used as a basement membrane substitute has been applied successfully for the management of persistent epithelial defects with and without ulcerations. Furthermore, multilayered AMT has been described to be useful for the treatment of deep corneal ulcers, descemetoceles, and small corneal perforations. This report describes a case of herpes simplex keratitis treated by amniotic membrane transplantation that resulted in high visual acuity and the absence of keratitis recurrent during two years

RESUMO

OBJECTIVE: To study the relationship between treatment with diode laser transscleral cyclophotocoagulation and development a neurotrophic keratitis due to the damage of the sensitive corneal innervation. METHODS: A study was conducted on 5 eyes of 5 patients who were treated with diode laser transscleral cyclophotocoagulation and soon developed neurotrophic ulcers. Personal characteristics of the patients were collected, as well as refraction and risk factors for corneal hypoesthesia, and the parameters of the laser used in the surgery. RESULTS: It was found that the 5 patients had predisposing factors of corneal hypoesthesia prior to surgery (chronic use of topical beta blockers, surgery with corneal incisions, diabetes mellitus, or corneal dystrophies); however none had developed neurotrophic keratitis until the cyclophotocoagulation was performed. It also showed that 4 of them were highly myopic, and they all were treated with high laser parameters (with an average of 2880 mW for 3s at an average surface of 275°), triggering neurotrophic ulcers between 10 and 35 days after surgery. CONCLUSION: Neurotrophic keratitis is a rare complication that can occur after diode laser transscleral cyclophotocoagulation, secondary to the damage of the long ciliary nerves. The emergence of this disorder can be triggered by the existence of previous risk factors, including high myopia, thus it is important to respect the recommended treatment parameters to prevent the development of this disorder.

RESUMO

El empleo de lentes de contacto se ha incrementado a nivel mundial. En la actualidad su uso no se restringe solamente a la corrección óptica, sino que se utilizan con fines terapéuticos, ya que generan comodidad y estética en múltiples afecciones oculares. Es de esperar el creciente aumento de las complicaciones relacionadas con el uso de estos, por ser la queratitis bacteriana potencialmente grave y devastadora para el globo ocular. Se realizó una revisión bibliográfica acerca de las úlceras corneales en portadores de lentes de contacto con el objetivo de describir su epidemiología y las formas de prevenir esta complicación(AU)


The use of contact lenses has increased worldwide. Their current uses comprise optical correction as well as therapeutic purposes since they bring comfortableness and esthetics in a number of ocular diseases. It is expected that contact lenses-related complications will grow because bacterial keratitis is potentially severe and devastating for the eyeball. A literature review on the presence of corneal ulcers in contact lens wearers was made to describe the epidemiology and the ways of preventing this complication(AU)
