Nieve visual en un paciente pediátrico / Visual snow in a paediatric patient

Caso clínico: Presentamos el caso de una niña de 11 años que refería fotofobia y visión continua de puntos blancos por ambos ojos (AO) de un año de evolución. La agudeza visual era de la unidad en AO con el resto de la exploración oftalmológica normal. La paciente fue derivada a la Unidad de Neuroftalmología y, una vez descartada enfermedad neurológica mediante analítica completa y pruebas de imagen, fue diagnosticada de nieve visual (NV). Discusión: La NV es un síntoma aislado que posiblemente forma parte del aura migrañosa y es referida por los pacientes como visión de numerosos y constantes puntos blancos en movimiento en el campo visual de AO. Puede producir una interferencia importante en las actividades diarias de los pacientes al alterar su calidad de vida y puede concluir en diagnósticos erróneos. En el caso de los pacientes pediátricos, además, presenta una gran dificultad diagnóstica por la compleja interpretación que supone en estos pacientes la presencia de la NV (AU)

Case report: The case is presented of an 11 year-old girl referring to a one year history of photophobia and continuously seeing white spots in both eyes. The patient had a visual acuity of unity in both eyes, and a normal eye examination, and was referred to the Neuro-ophthalmology Unit. Once complete laboratory and imaging tests ruled out the possibility of any neurological pathology, she was diagnosed with visual snow (VS). Discussion: VS is an isolated symptom, possibly part of the migraine aura, that is referred by patients reporting numerous and constant white dots moving in the visual field of BE. It can significantly interfere with patient's daily activities by altering their quality of life, and ending up as a misdiagnosis. Paediatric patients also present a diagnostic challenge due to the complex interpretation that the presence of VS involves in them (AU)

Cierre angular secundario al uso de lorazepam en paciente con miopía magna / Angle closure secondary to the use of lorazepam in patient with myopia magna

CASO CLÍNICO: Miope magna con cámara anterior estrecha que presentó cierre angular secundario a lorazepam. DISCUSIÓN: El cierre angular generalmente ocurre en pacientes predispuestos desencadenado por factores precipitantes. Muchos fármacos de uso rutinario en la práctica clínica podrían ejercer como factor responsable del cierre angular secundario

CASE REPORT: Myopic magna with narrow anterior chamber that presented with a secondary angle closure due to lorazepam. DISCUSSION: Angle closure usually occurs in predisposed patients and is triggered by precipitating factors. Many drugs routinely used in clinical practice could act as a factor responsible for the secondary angle closure
