RESUMO

Introducción: Evaluar cuantitativamente el grosor macular y de la capa de fibras nerviosas en pacientes con esclerosis múltiple en relación con la escala expandida del estado de discapacidad (EDSS) con o sin antecedentes previos de neuritis óptica. Métodos: Sesenta y dos pacientes diagnosticados de esclerosis múltiple (53 remitente recidivante y 9 secundariamente progresiva) y 12 libres de enfermedad fueron reclutados para el estudio. Se les realizó una exploración oftalmológica, incluyendo el análisis cuantitativo de la capa de fibras nerviosas retinianas y el grosor macular mediante tomografía óptica de coherencia. Los pacientes fueron clasificados según la escala EDSS en: A: inferior a 1,5; B: entre 1,5 y 3,5, y C: superior a 3,5. Resultados: El grosor medio ± desviación estándar de la capa de fibras nerviosas en los grupos control, A, B y C fue de 103,35 ± 12,62, 99,04 ± 14,35, 93,59 ± 15,41 y 87,36 ± 18,75 μm, respectivamente, con diferencias estadísticamente significativas (p < 0,05). En pacientes sin una historia previa de neuritis, o con un episodio de esta patología entre 3 y 6 meses de evolución o anterior a 6 meses, el grosor medio fue de 99,25 ± 13,71, 93,92 ± 13,30, 80,07 ± 15,91 μm, respectivamente, con diferencias significativas (p < 0,05). El grosor macular medio en el grupo control, A, B y C se situó en 220,01 ± 12,07, 217,78 ± 20,02, 217,68 ± 20,77 y 219,04 ± 24,26 μm, respectivamente. Las diferencias observadas entre grupos no fueron estadísticamente significativas. Conclusiones: El grosor medio de la capa de fibras nerviosas en pacientes con esclerosis múltiple se relaciona con el nivel en la escala EDSS. Los pacientes con historia previa de neuritis óptica cursan con una disminución del grosor de esta capa respecto a aquellos sin antecedentes de neuritis. El grosor macular no se relaciona con el grado de afectación en la EDSS


Introduction: Quantitative assessment of macular and nerve fibre layer thickness in multiple sclerosis patients with regard to expanded disability status scale (EDSS) and presence or absence of previous optic neuritis episodes. Methods: We recruited 62 patients with multiple sclerosis (53 relapsing-remitting and 9 secondary progressive) and 12 disease-free controls. All patients underwent an ophthalmological examination, including quantitative analysis of the nerve fibre layer and macular thickness using optical coherence tomography. Patients were classified according to EDSS as A (lower than 1.5), B (between 1.5 and 3.5), and C (above 3.5). Results: Mean nerve fibre layer thickness in control, A, B, and C groups was 103.35 ± 12.62, 99.04 ± 14.35, 93.59 ± 15.41, and 87.36 ± 18.75 μm respectively, with statistically significant differences (P < .05). In patients with no history of optic neuritis, history of episodes in the last 3 to 6 months, or history longer than 6 months, mean nerve fibre layer thickness was 99.25 ± 13.71, 93.92 ± 13.30 and 80.07 ± 15.91 μm respectively; differences were significant (P < .05). Mean macular thickness in control, A, B, and C groups was 220.01 ± 12.07, 217.78 ± 20.02, 217.68 ± 20.77, and 219.04 ± 24.26 μm respectively. Differences were not statistically significant. Conclusions: The mean retinal nerve fibre layer thickness in multiple sclerosis patients is related to the EDSS level. Patients with previous optic neuritis episodes have a thinner retinal nerve fibre layer than patients with no history of these episodes. Mean macular thickness is not correlated to EDSS leve

RESUMO

Introducción. La carcinomatosis meníngea (CM) es una complicación rara de las neoplasias en estadios avanzados. El 5% de las neoplasiasse presentan como una CM. Clínicamente se manifiestan con diplopía, papiledema y/o déficit visual. Ante su sospecha es necesario la realización de una resonancia magnética nuclear y una punción lumbar para su diagnóstico. Caso clínico. Paciente de 54 años diagnosticado de adenocarcinoma de próstata con oscurecimientos visuales y papiledema como primera manifestación de una carcinomatosis meníngea. Discusión. Se discute como proceder ante un edema de papila bilateral secundario a hipertensión intracraneal. Conclusiones. Se resalta la importancia de considerar la posibilidad de invasión meníngea de una neoplasia, cuando nos encontramos un paciente con déficit neurológico y/o visual sin datos de infección o lesión ocupante de espacio (AU)


Introduction. Meningeal carcinomatosis (MC) is a rare complication of late-stage tumors. The 5% of the tumors are presented as a MC. Clinically it was manifested with diplopia, papilledema and / or visual deficits. MC is usually diagnosed by magnetic resonance imaging and cerebrospinal fluid analysis. Case report. A 54-year old man with prostate adenocarcinoma,presented to the emergency service with papilledema, and visual obscurations as first manifestation of meningeal carcinomatosis. Discussion. We discuss how to proceed before a bilateral papilledema due to intracranial hypertension. Conclusions. The importance of considering the possibility of a malignant meningeal invasion, when we find a patient with neurologicaland / or visual deficits without evidence of infection or space occupying lesion (AU)
