"La deficiencia acuosa es la alteracion mas frecuente de la pelicula lagrimal que determina ojo seco. A los sintomas clasicos de ardor, sensacion de arenilla, fotofobia. etc., se agregan signos como disminucion del menisco lagrimal, secrecion mucosa, queratitis punctata, filamentos y otros, que junto a los colorantes vitales y examenes especificos, hacen que el diagnostico no sea problematico. Los pacientes mas dificiles de tratar son los que presentan un sindrome de Sjogren, porque hay ademas un compromiso inmunologico. En ellas las lagrimas de sustitucion, la oclusion de los puntos lagrimales, los mucoliticos, la vitamina A, la ciclosporina, etc., a veces no dan el resultado esperado y nos vemos obligados a realizar tarsorrafia, reseccion de conjuntiva o tratar de perforacion corneal. Finalmente, es posible tener areas de desecacion si hay blefaropatias y/o irregularidades de la superficie ocular (AU)."@es
