Aguirre-Balsalobre,F.E.; Coloma-González,I.T.; Mengual-Verdú,E.N.;
Archivos de la Sociedad Espa?ola de Oftalmología , 2006, DOI: 10.4321/S0365-66912006000100008
Abstract: clinical case: the case of a three-year-old patient with neurofibromatosis type i is presented. ophthalmologic evaluation revealed, by means of magnetic resonance imaging, the presence of a silent glioma in the optic nerve of the left eye. discussion: neurofibromatosis-1 can present in multiple ways to the ophthalmologist, with a glioma of the optic nerve being one of the most frequent central nervous system presentations in this illness. generally the glioma affects the optic chiasm and its course is indolent, with conservative management and close monitoring usually being advised until progression is defined.

Abstract: Caso clínico: Se presenta el caso de una paciente de tres a os de edad con neurofibromatosis tipo 1. La exploración oftalmológica reveló, mediante resonancia nuclear magnética, la presencia de un glioma de curso silente en el nervio óptico del ojo izquierdo. Discusión: La neurofibromatosis-1 produce múltiples manifestaciones en el campo oftalmológico, siendo los gliomas de la vía óptica los tumores del sistema nervioso central más frecuentes en la enfermedad. Por lo general suelen afectar al quiasma y su curso suele ser indolente, aceptándose un tratamiento conservador con seguimiento estrecho hasta que se detecte progresión.

Abstract: Introducción: El botulismo es poco frecuente en la actualidad. La toxina botulínica produce una parálisis muscular progresiva que puede producir la muerte del paciente por parada de los músculos respiratorios. Caso clínico: Dos pacientes hermanos, adictos a la cocaína, acudieron al Servicio de Urgencias por disminución de la agudeza visual cercana, con midriasis bilateral. A los dos días presentaban, además, ptosis palpebral, disfunción asimétrica de la motilidad ocular extrínseca, y vómito. Discusión: Ante la presencia de una parálisis de la acomodación con una midriasis bilateral que responde a pilocarpina, se debe considerar el botulismo como una posible etiología. Introduction: Botulism is currently an uncommon disease in which the botulinum toxin causes a progressive muscular paralysis that can lead to the death due to a failure of respiratory muscles. Clinical case: Two brothers, both addicted to cocaine, came to the casualty department because of a decrease of near visual acuity and bilateral mydriasis. Two days later, they developed eyelid ptosis, asymmetric dysfunction of the extraocular muscles and vomiting. Discussion: The presence of a paralysis of accommodation, with bilateral mydriasis that reacts to pilocarpine, makes it necessary to consider botulism as a possible cause.

Abstract: Objetivo: Evaluar la reducción del astigmatismo corneal preexistente en la cirugía de catarata mediante incisiones limbares relajantes (ILRs). Método: Estudio prospectivo de dos grupos de pacientes (tratamiento y control) con astigmatismo prequirúrgico ≥1D. Los 30 pacientes del grupo control fueron sometidos a facoemulsificación por incisión temporal en córnea clara y los 32 pacientes del grupo tratamiento a ILRs junto a facoemulsificación por incisión temporal en córnea clara. Se usó el test de Holladay para valorar la eficacia del tratamiento. Asimismo, presentamos un peque o estudio de la prevalencia y distribución del astigmatismo en nuestra población de trabajo. Resultados: El seguimiento promedio de los 62 pacientes fue de 3 meses, con un cambio astigmático medio a los 3 meses de -0.55D (-0,75 a -0,35) en el grupo tratamiento y de 0.04D (-0,3 a 0,3) en el grupo control (p<,000). Conclusiones: Las ILRs son un método sencillo y efectivo para conseguir reducir el astigmatismo previo durante la cirugía de catarata y con ello la dependencia de gafa.

Abstract: Introducción: La enfermedad de Graves es una enfermedad de base autoinmune en la cual existe una infiltración por linfocitos activados en el tejido retroorbitario. Estos linfocitos activados se caracterizan por aumentar la expresión de receptores de somatostatina en su superficie que median la respuesta inflamatoria. Objetivo: Valorar la efectividad de la gammagrafía con 111In-octreótido en la identificación de actividad orbitaria en la Enfermedad de Graves y valorar qué pacientes son subsidiarios de recibir tratamiento con análogos de la somatostatina, así como su evolución con el tratamiento, según un protocolo establecido con el Servicio de Medicina Nuclear. Métodos: Se estudió un grupo de dieciocho pacientes con oftalmopatía tiroidea sintomática de dos meses a cuatro a os de evolución. Se les inyectó 6 mCi de 111In-octreótido vía endovenosa siendo estudiados mediante SPECT a las cuatro y veinticuatro horas. Cuatro enfermos, todos en fase activa, mostraron captación orbitaria, por lo que fueron tratados con lanreotida 60 mg cada quince días. Se controló a estos pacientes a los tres meses con un nuevo estudio clínico-gammagráfico. Resultados: En nuestra serie, de los cuatro pacientes que presentaron receptores, todos ellos con evolución menor de dieciséis meses, tres respondieron bien al tratamiento según la valoración posterior. Conclusión: La gammagrafía con octreótido es un procedimiento útil que diferencia las fases activas, subsidiarias de tratamiento inmunosupresor, en pacientes con oftalmopatía tiroidea. El tratamiento con análogos de la somatostatina fue eficaz en nuestra serie. Introduction: Graves’ disease, which has an autoimmune basis, is associated with the infiltration of activated lymphocytes into the retrobulbar tissues of the eye. These activated lymphocytes express somatostatin receptors on their surface which mediate the inflammatory response. Objective: To evaluate the efficiency of 111In-Octreotide scintigraphy in the identification of orbital activity in Graves’ disease and the usefulness of treatment with a somatostatin analogue, based on a pre-established protocol within the Nuclear Medicine Department. Methods: We studied a group of eighteen patients with symptomatic Graves’ ophthalmopathy of between two months and four years duration. We injected 6 mCi of 111In-Octreotide parenterally, and performed scintigraphy four and twenty-four hours later. Four patients, all in the active phase, showed orbital somatostatin receptors, for which they were treated with lanreotide 60 mg every fifteen days for three months. Patients were rev

Abstract: case report: the effect of a somatostatin analogue in a patient with graves? ophthalmopathy is presented, including data on the dose requirements and the results of therapy. discussion: there are few effective options for the management of graves? ophthalmopathy, a cell-mediated immune co-morbidity of thyroid disease. somatostatin analogues inhibit lymphocyte proliferation and activation, and accumulate in the orbital tissue during the active ophthalmopathy. because of this, such therapy is able to inactivate the ophthalmopathy without complications occurring.
