ABSTRACT

CASO CLÍNICO: Mujer de 78 años que se presenta con una tumoración corneal no pigmentada y vascularizada en ojo izquierdo de dos meses de evolución y sin antecedentes oftalmológicos. Se realizó exéresis y estudio histopatológico con diagnóstico de nevus melanocítico atípico limbar. DISCUSIÓN: La pigmentación corneal procede, en la mayoría de los casos, de la extensión de lesiones de conjuntiva y limbo, o de la migración de sus melanocitos tras una agresión corneal previa. Debemos realizar biopsia y estudio anatomopatológico puesto que, aunque debemos descartar enfermedad precancerosa y maligna (melanosis adquirida primaria y melanoma conjuntival), también existen condiciones benignas como el caso que nos ocupa


CASE REPORT: A 78-year-old-woman presented with a corneal non-pigmented vascularised tumour of her left eye, of 2 months onset, but with no previous ocular disorders. Surgical excision was performed, and the histopathological study showed the lesion to be an atypical melanocytic nevus of the limbus. DISCUSSION: Corneal pigmented lesions tend to occur as a result of conjunctival or sclerocorneal limbus lesions spreading or arising de novo from melanocytic cells that have migrated following corneal injury. A biopsy should be carried out to type and distinguish benign lesions (nevus) from pre-malignant or malignant lesions (primary acquired melanosis or conjunctival melanoma)

ABSTRACT

Caso clínico: Mujer de 60 años que acudió de urgencia por pérdida súbita de visión en ojo izquierdo. El estudio fundoscópico mostró desprendimiento de retina exudativo. En la anamnesis refería disnea de un año de evolución y edemas periféricos. El estudio sistémico reveló la existencia de hipertensión pulmonar recibiendo tratamiento diurético (furosemida). El desprendimiento se resolvió a las 48h. Estudios posteriores determinaron una hipertensión pulmonar primaria. Discusión: El desprendimiento de retina exudativo puede ser el primer signo clínico de una enfermedad grave como la hipertensión pulmonar primaria. El oftalmólogo puede ser el primero en detectar esta enfermedad (AU)


Case report: A 60 year old woman who was seen in the emergency department due to sudden loss of vision in left eye. The fundoscopy study showed exudative retinal detachment. The patient referred to dyspnea and peripheral edema of one year duration during the anamnesis. The systematic study revealed the existence of pulmonary hypertension, and she was given diuretic treatment (furosemide). After 48h the detachment was resolved. Subsequent studies identified a primary pulmonary hypertension. Discussion: Exudative retinal detachment can be the first clinical sign of a serious disease like primary pulmonary hypertension. The ophthalmologist can be the first to detect this disease (AU)

ABSTRACT

Objetivo: Conocer la prevalencia de retinopatía diabética (RD) y evaluar nuestra experiencia en cribado RD en un estudio llevado a cabo entre el Servicio de Oftalmología del Hospital General Universitario de Alicante y el Departamento 19 de Atención Primaria de Alicante mediante la utilización de retinografías con cámara no midriática y telemedicina. Métodos: Estudio descriptivo transversal de 2.435 pacientes diabéticos desde el 1 de febrero de 2006 hasta el 1 de febrero de 2009, obteniéndose tres retinografías de 45° en ambos ojos de cada pacientes mediante cámara no midriática que son enviadas al Servicio de Oftalmología por la intranet del Hospital, donde son valoradas por dos oftalmólogos expertos en retina que emiten un informe individualizado de cada paciente. Resultados: La prevalencia de retinopatía diabética fue del 17,90%. De ellos un 80,73% presentaban RD no proliferativa leve y moderada, y un 12,16% RD no proliferativa severa y 2,29% RD proliferativa y 4,82% maculopatía diabética asociada a algún grado de retinopatía. En 41 pacientes (1,69%) las retinografías obtenidas no fueron valorables. Conclusiones: Destacamos las ventajas de la teleoftalmología en el cribado de pacientes diabéticos al permitir un diagnóstico y tratamiento precoces, y mejorar el circuito de comunicación entre atención primaria y especializada(AU)


Objective: To determine the prevalence of diabetic retinopathy (DR) and evaluate our experience in DR screening in a study carried out between the Ophthalmology Department of the University General Hospital of Alicante and Department 19 Primary Care of Alicante by using a non-retinal mydriatic camera and telemedicine. Material and methods: A descriptive, cross-sectional study was conducted on 2,435 diabetic patients from 1 February 2006 to 1 February 2009. Three 45° retinographies of both eyes of each patient were obtained and sent to the Department of Ophthalmology via the hospital intranet. These were then evaluated by 2 ophthalmologists, experts in the retina, with each issuing an individualized report for each patient. Results: The prevalence of DR was 17.90%, with 80.73% of them having mild-moderate proliferative DR, 12.16% severe non-proliferative DR, 2.29% proliferative DR, and 4.82% with diabetic maculopathy associated with any level of retinopathy. The retinographies were considered low quality in 41 patients (1.69%). Conclusions: We highlight the benefits of the tele-ophthalmology in screening diabetic patients to enable early diagnosis and treatment, and improving the circuit of communication between primary and specialist care(AU)

ABSTRACT

OBJECTIVE: The purification of commercially prepared triamcinolone acetonide is important in order to avoid the potential toxic side-effects of the solvent benzyl alcohol. We present a new technique for preparation of pure triamcinolone acetonide by dissolving the powder in sterile distilled water with no additional solvents. As the triamcinolone powder is relatively insoluble in water, we describe the sterile method used for the preparation and control of this suspension. MATERIALS AND METHODS: The triamcinolone acetonide is prepared in our hospital pharmacy, under optimum sterile conditions, and then packaged in a primary vial, sealed and sterilized in an autoclave at 121°C. This vial contains an individual dose of 4mg/0.1ml. RESULTS: A final dose for an intravitreal administration of 3.77mg/0.1ml triamcinolone acetonide was obtained using high pressure liquid chromatography (HPLC). The chemical, physical and microbiological stability allows the solution to be kept at a temperature of 2-8°C for 6 months. CONCLUSIONS: A rapid method is presented for preparing triamcinolone acetonide in pure state without preservatives in a concentration near the standard dose and under optimum sterile conditions.

ABSTRACT

Objetivo: La purificación del preparado comercial de triamcinolona acetónido disponible es importante para evitar el efecto potencialmente tóxico del disolvente alcohol bencílico. Presentamos una nueva técnica de preparación de triamcinolona en polvo, a partir de su forma pura, sin disolventes y diluida con agua destilada estéril. Dada su escasa solubilidad en aguase describe cómo preparar y controlar dicha suspensión. Material y método: El acetónido de triamcinolona es preparado por el Servicio de Farmacia del Hospital, en condiciones de máxima esterilidad, bajo campana de flujo laminar. La suspensión de triamcinolona es envasada en un vial primario, capsulado y posteriormente esterilizado en autoclave a 121 ◦C. Del vial primario se obtienen dosis individualizadas de 4 mg/0,1 ml. Resultados: Se obtiene la dosis real administrada (3,77 mg/0,1 ml) mediante cuantificación de triamcinolona por cromatografía líquida de alta resolución (HPLC). La estabilidad física, química y microbiológica conservando el vial entre 2-8◦ se mantiene a los 6 meses. Conclusión: Se presenta un método de preparación de triamcinolona en estado puro, obteniendo una concentración muy próxima a la dosis óptima, evitando el uso de disolventes y con máxima garantía de esterilidad(AU)

ABSTRACT

Objetivo: Valorar los resultados quirúrgicos a largo plazo de la trabeculotomía-trabeculectomía combinada (TTC) como tratamiento preferente del glaucoma congénito primario. Métodos: Se seleccionaron 22 ojos de 14 pacientes consecutivos con glaucoma congénito primario en los que se empleó la TTC como procedimiento inicial entre 1981 y 2005. Se introdujo en una base de datos la información relacionada con la historia familiar, edad de inicio del glaucoma, síntomas y signos, integridad corneal, presión intraocular (PIO), gonioscopia, cirugía, complicaciones postoperatorias, agudeza visual, defecto de refracción, microscopia endotelial, longitud axial, campos visuales y estado final de la papila. El resultado de la presión intraocular fue evaluado usando el análisis de supervivencia Kaplan-Meier. Resultados: Las probabilidades acumuladas de éxito después de realizar una TTC como procedimiento inicial fueron del 95,5% a los 12 meses y del 78,2% a los 24 meses, manteniéndose esta proporción durante 15 años de seguimiento. Cuatro ojos (18,1%) requirieron más de un procedimiento debido a una PIO elevada persistente. Las complicaciones postoperatorias fueron raras. Al final del seguimiento, de 12 ojos de 8 pacientes cooperadores, la mejor agudeza visual corregida fue igual o mayor de 0,5 en el 75% (9 ojos). Conclusiones: La TTC como cirugía primaria ofrece una alta eficacia a largo plazo en el control de la PIO sin tratamiento farmacológico, mostrando mínimas complicaciones quirúrgicas y una baja incidencia de reintervenciones


Purpose: To evaluate the long-term outcome of trabeculotomy-trabeculectomy as the primary surgical treatment for primary congenital glaucoma. Methods: Twenty-two eyes of 14 consecutive patients with primary congenital glaucoma who underwent combined trabeculotomy-trabeculectomy as the initial procedure between 1981 and 2005 were selected for review. Records of ocular family history, age at onset of glaucoma, symptoms and signs, corneal integrity, intraocular pressure (IOP), gonioscopy, surgery, postoperative complications, visual acuity, refractive error, endothelial microscopy, axial length, visual fields and final status of the optic nerve head were entered into a computer database. The outcome, in terms of IOP obtained, was evaluated using Kaplan-Meier survival analysis. Results: Cumulative probabilities of success, after performing combined trabeculotomy-trabeculectomy as the initial operative procedure, were 95.5% after 12 months and 78.2% after 24 months, with this rate being maintained during 15 years of follow-up. Four eyes (18.1%) required more than one operative procedure because of persistent raised IOP. Postoperative complications were rare. At the time of the last follow-up, of 12 eyes from 8 co-operative patients, the final best spectacle-corrected visual acuity was 0.5 (20/40) or better, in 75% (9 eyes). Conclusion: Combined trabeculotomy-trabeculectomy as the primary surgical procedure offers long-term high efficacy in the control of IOP without medical treatment, is rarely associated with surgical complications, and a low need for re-operations (Arch Soc Esp Oftalmol 2008; 83: 479-486)

ABSTRACT

CASE REPORT: A 13-year-old female presented as an emergency, complaining of loss of vision during the last three months. On examination she had bilateral posterior subcapsular cataracts with snowflake opacities and a blood glucose of 731 mg/dl with ketoacidosis. DISCUSSION: True diabetic cataracts should be differentiated from other lens opacities in diabetics. The latter, identical to senile cataracts, are very common but appear earlier in diabetic patients and are not considered true diabetic cataracts (which are rare). Although true diabetic cataracts are infrequent, the appearance of lens opacities in young patients should alert the ophthalmologist to the existence of diabetes mellitus.

ABSTRACT

Caso clínico: Niña de 13 años que acude a urgencias por pérdida de visión de 3 meses de evolución. En la exploración presentaba cataratas subcapsulares posteriores en ambos ojos con opacidades aisladas en copo de nieve y glucemia de 731 mg/dl con cetoacidosis. Discusión: Hay que diferenciar la verdadera catarata diabética de las opacidades cristalinianas en los diabéticos. Estas últimas son muy frecuentes, tienen idénticas características a las seniles, son más tempranas y no deberían considerarse cataratas diabéticas. Aunque la verdadera catarata diabética es rara, la aparición de opacidades cristalinianas en jóvenes debe alertar al oftalmólogo de la posibilidad de una Diabetes Mellitus (AU)

ABSTRACT

Objetivo: Valorar la correlación entre las variaciones en la sensibilidad de contacto y la función trófica del epitelio corneal del ojo de conejo, tras la denervación periférica que originan heridas circulares (trepanaciones) en la córnea, similares a las realizadas durante las queratoplastias penetrantes en humanos. Métodos: El estudio incluyó 40 ojos de conejo, de los que en 12 fueron practicadas trepanaciones completas con rotación del botón corneal (TCR) y en otros 12, trepanaciones parciales que afectaron al menos dos terceras partes del espesor total de la córnea (TSR). Los 16 ojos restantes no fueron intervenidos y sirvieron como controles. La sensibilidad y trofismo epiteliales fueron evaluados tres meses después de las queratoplastias experimentales. La sensibilidad mecánica fue explorada con el estesiómetro de Cochet y Bonnet (filamento de nylon n.º 12). La función trófica se valoró calculando la velocidad de reepitelización de desepitelizaciones producidas en la superficie de la córnea mediante la aplicación de un papel impregnado en n-heptanol. Resultados: A los tres meses de la intervención, la sensibilidad de contacto en el centro de las córneas intervenidas registraba variaciones muy importantes (umbrales mecánicos: 240ñ0 mg/S en las TCR y 179ñ20 mg/S en las TSR, vs 88ñ10 mg/S en los ojos control, p<0,001 en ambos casos). En cambio, la capacidad de las córneas trepanadas para regenerar las lesiones practicadas en su epitelio fue similar a la de los ojos controles, no intervenidos. Tampoco se encontraron diferencias en la función reepitelizadora al comparar las córneas con trepanaciones completas con las de trepanación de espesor parcial. Conclusiones: Los resultados obtenidos sugieren que el epitelio de las córneas trasplantadas no debe presentar problemas en su mantenimiento trófico, a pesar de la profunda hipoestesia que habitualmente se registra en su superficie. La trascendencia clínica de este hallazgo nos obliga a profundizar en las bases anatómicas, fisiológicas y bioquímicas de esta interacción entre neuronas y epitelio corneal (AU)
