Proptosis aguda como primera manifestación de un carcinoma de pulmón / Acute proptosis as first symptom of a lung carcinoma

Objetivo/Método: Presentamos el caso de un paciente de 57 años que acudió de urgencia a nuestro servicio refiriendo una clínica de proptosis aguda en el ojo derecho, fiebre y acusado malestar general. Tras realizar el estudio clínico, oftalmológico y radiológico correspondiente, se demostró la presencia de una tumoración intraorbitaria extraconal como causa del exoftalmos. Resultados/Conclusiones: Las pruebas complementarias oportunas revelaron la existencia de un carcinoma microcítico de pulmón como causa de la metástasis que afectaba a la órbita derecha. Destacamos la excelente respuesta a la quimioterapia tanto del tumor primario pulmonar como de la metástasis orbitaria (AU)

[Acute proptosis as first symptom of a lung carcinoma]. / Proptosis aguda como primera manifestación de un carcinoma de pulmón.

PURPOSE/METHOD: We present the case of a 57-year-old patient who was visited in our ophthalmology department complaining of acute right ocular proptosis, fever and malaise. The clinical, ophthalmic and radiologic examination showed the presence of an extraconal orbital tumor as the cause of this exophthalmos. RESULTS/CONCLUSION: Further complementary studies revealed a small cell carcinoma of the lung metastatic to the right orbit. We report the excellent response to chemotherapy both of the primary lung neoplasm and the orbital metastasis.

[Contrast vision in patients with aphakia and pseudophakia]. / Etude sur la vision de contraste chez les aphakes et les pseudophakes.

A study was carried out on contrast vision in 26 aphakic patients (48 operated eyes) and 37 pseudophakic patients (37 operated eyes); in some cases an intraocular PMMA lens had been implanted, in others an IOGEL (polimacon) had been implanted. The level of sensitivity to contrast in both cases was found to be lower than expected by the Vistech company for aphakics. At the same time a comparative study was carried out of the results obtained for sharpness of vision in aphakic and pseudophakic patients, with the traditional tests of Snellen (long sightedness) and Parinaud (short sightedness) and those obtained with the Contrast Sensitivity Test System (VCTS-6500 for long sightedness and VCTS-6000 for short sightedness). The former tests were found to overestimate the visual results. Corrected aphakia was found to affect the sensitivity to contrast more than in pseudophakic cases. Nevertheless no significant differences were found between contrast vision in eyes with PMMA lens implantation and eyes with IOGEL (polimacon) lens implantation. Summing up, alterations in the sensitivity to contrast undetected by the simple measurement of visual sharpness were found.

[Influence of topical administration of diclofenac on the reduction of intraocular pressure induced by timolol in healthy subjects]. / Influence de l'administration topique de diclofénac sur la réduction de la pression intraoculaire produite par le timolol chez des sujets sains.

The presence or absence of an interaction between topical diclofenac (nonsteroidal antiinflammatory agent) and topical timolol (beta-blocker) was studied in 37 eyes. We instilled one drop of diclofenac several times into the patient's right eye and one drop of timolol into the same eye. We measured intraocular pressure in both eyes twice and compared the results in both eyes with the baseline intraocular pressure and with the pressure after administration of diclofenac alone and timolol alone. The joint use of both drugs did not modify the decrease in the ocular pressure induced by timolol. We can therefore use timolol and diclofenac together when a combination of antiinflammatory and beta-blocker agents is required.

Diclofenac sódico versus dexametasona en el pretratamiento de la trabeculoplastía con láser de argón / Diclofenac sodium vs dexametasone therapy before argon laser trabeculoplasty

Realizamos un estudio prospectivo, randomizado y doble ciego en 40 pacientes, para comparar la influencia que la administración tópica de un nuevo inhibidor de la síntesis de prostaglandinas -el diclofenac sódico al 0,1%- podría tener en el curso postoperatorio de ojos con glaucoma de ángulo abierto que fueron sometidos a una trabeculoplastia con láser de argón. No hallamos diferencias estadísticamente significativas entre los dos grupos en cuanto al incremento inmediato de la presión intraocular y la respuesta inflamatoria postoperatoria que siguieron a la laserterapia. Sin embargo, pensamos que el colirio de diclofenac sódico al 0,1% es útil como agente antiinflamatorio tópico después de la trabeculoplastia, por carecer de los efectos secundarios de los corticosteroides

[A new case of Cohen's syndrome]. / Une nouvelle observation du syndrome de Cohen.

We report a detailed description of ocular alterations, especially uveal coloboma, as shown in a patient with Cohen's syndrome. We also report new lesions, not previously described in the revised bibliography: lens and optic head colobomas, hyaloid artery and anterior "vasculosa lentis" tunica vestige. The most characteristic ocular alterations previously described in the bibliography are eyelid antimongoloid fissures, strabismus and myopia.
