Las molestias se solapan. Este art\u00edculo muestra pistas t\u00edpicas y explica cu\u00e1ndo tiene sentido un examen.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Alergia y ojo seco: dos causas, molestias parecidas<\/h2>\n\n\n<p class=\"wp-block-paragraph\">El enrojecimiento y el lagrimeo aparecen en ambas afecciones. El patr\u00f3n de las molestias y los hallazgos en los p\u00e1rpados y la superficie ocular ayudan a distinguirlas.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Picor o ardor: la pista m\u00e1s importante<\/h2>\n\n\n<p class=\"wp-block-paragraph\">El tipo de molestias ayuda a buscar la causa:<\/p>\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Alergia:<\/strong> predomina el <strong>picor<\/strong>, a menudo con unas fuertes ganas de frotarse los ojos.<\/li>\n\n<li><strong>Ojo seco:<\/strong> predominan el <strong>ardor y la sensaci\u00f3n de arenilla<\/strong> o de cuerpo extra\u00f1o, m\u00e1s escozor que picor.<\/li>\n<\/ul>\n\n\n<p class=\"wp-block-paragraph\">Un picor intenso apunta m\u00e1s bien a una alergia; el ardor y la sensaci\u00f3n de cuerpo extra\u00f1o, m\u00e1s bien a un ojo seco. Los s\u00edntomas aislados no confirman el diagn\u00f3stico; adem\u00e1s, ambas afecciones pueden darse a la vez.<\/p>\n\n\n<h2 class=\"wp-block-heading\">C\u00f3mo surge el picor en la alergia y el ardor en el ojo seco<\/h2>\n\n\n<p class=\"wp-block-paragraph\">En una conjuntivitis al\u00e9rgica, las c\u00e9lulas inmunitarias liberan, entre otras sustancias, histamina. Esto puede provocar picor, enrojecimiento e hinchaz\u00f3n. Qu\u00e9 procesos intervienen depende tambi\u00e9n del tipo de alergia.<\/p>\n\n\n<p class=\"wp-block-paragraph\">En el ojo seco, la pel\u00edcula lagrimal o la superficie ocular han perdido su equilibrio. Una pel\u00edcula lagrimal inestable y cambios en los sensibles nervios de la c\u00f3rnea pueden provocar ardor, pinchazos o sensaci\u00f3n de cuerpo extra\u00f1o. El trabajo prolongado con pantallas puede empeorar las molestias, porque muchas personas parpadean menos o de forma incompleta mientras lo hacen.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Otros signos que distinguen la alergia del ojo seco<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Algunos patrones ayudan adem\u00e1s a distinguirlos:<\/p>\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Molestias acompa\u00f1antes:<\/strong> los estornudos o el picor de nariz apuntan adem\u00e1s a una alergia. Pero el ojo seco tambi\u00e9n puede presentarse junto con otras enfermedades.<\/li>\n\n<li><strong>Secreci\u00f3n:<\/strong> en la alergia, la secreci\u00f3n es acuosa, a veces con hebras de moco blanquecinas y filamentosas. En el ojo seco, los ojos <a href=\"https:\/\/smartdryeyes.com\/es\/ojos-llorosos-que-se-sienten-secos\/\">lagrimean m\u00e1s bien por reflejo<\/a>, porque la superficie irritada da la voz de alarma.<\/li>\n\n<li><strong>P\u00e1rpados y conjuntiva:<\/strong> unos p\u00e1rpados hinchados y una conjuntiva vidriosa e hinchada en ambos ojos apuntan a una alergia. Los bordes de los p\u00e1rpados engrosados y enrojecidos indican m\u00e1s bien una alteraci\u00f3n de las gl\u00e1ndulas de Meibomio.<\/li>\n\n<li><strong>Patr\u00f3n temporal:<\/strong> las alergias al polen suelen ser estacionales; la \u00e9poca exacta de polinizaci\u00f3n var\u00eda seg\u00fan la regi\u00f3n y el tiempo. Una alergia a los \u00e1caros del polvo puede causar molestias todo el a\u00f1o. Las molestias de sequedad pueden aumentar, por ejemplo, con el aire seco, el viento o el trabajo prolongado con pantallas.<\/li>\n<\/ul>\n\n\n<h2 class=\"wp-block-heading\">Alergia y ojo seco a la vez: una combinaci\u00f3n frecuente<\/h2>\n\n\n<p class=\"wp-block-paragraph\">La alergia y el ojo seco pueden aparecer juntos. Una revisi\u00f3n encontr\u00f3 con frecuencia ambos diagn\u00f3sticos en los grupos estudiados; sin embargo, las estimaciones variaban considerablemente entre los estudios. La inflamaci\u00f3n al\u00e9rgica puede sobrecargar a\u00fan m\u00e1s una superficie ocular que ya es sensible.<\/p>\n\n\n<p class=\"wp-block-paragraph\">A esto se suman los propios medicamentos contra la alergia. Algunos <strong>antihistam\u00ednicos en comprimidos<\/strong> pueden frenar la producci\u00f3n de l\u00e1grimas, porque bloquean de paso una sustancia mensajera que la gl\u00e1ndula lagrimal necesita para funcionar. Este efecto es m\u00e1s marcado con los principios activos m\u00e1s antiguos; con los m\u00e1s nuevos, los resultados de los estudios var\u00edan. Si nota cada vez m\u00e1s ardor mientras toma comprimidos para la alergia, com\u00e9ntelo con su m\u00e9dico.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Tratamiento: por qu\u00e9 la alergia y el ojo seco necesitan enfoques terap\u00e9uticos distintos<\/h2>\n\n\n<p class=\"wp-block-paragraph\">En la alergia y en el ojo seco pueden tener sentido tratamientos distintos. Contra las molestias al\u00e9rgicas pueden plantearse, seg\u00fan los hallazgos, colirios antial\u00e9rgicos; en el ojo seco, el tratamiento depende de la causa de la alteraci\u00f3n de la pel\u00edcula lagrimal. Para el d\u00eda a d\u00eda, estas indicaciones ayudan:<\/p>\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fr\u00edo o calor:<\/strong> las compresas fr\u00edas alivian el picor al\u00e9rgico. Las <a href=\"https:\/\/smartdryeyes.com\/es\/compresas-calientes-e-higiene-palpebral\/\">compresas calientes<\/a>, en cambio, ayudan a las gl\u00e1ndulas de Meibomio obstruidas.<\/li>\n\n<li><strong>Gotas sin conservantes:<\/strong> los conservantes como el cloruro de benzalconio pueden irritar a\u00fan m\u00e1s la superficie ocular. Las l\u00e1grimas artificiales sin conservantes arrastran el polen y alivian una pel\u00edcula lagrimal seca, as\u00ed que ayudan en ambos casos. M\u00e1s informaci\u00f3n: <a href=\"https:\/\/smartdryeyes.com\/es\/elegir-gotas-ojo-seco\/\">c\u00f3mo elegir las gotas adecuadas<\/a>.<\/li>\n\n<li><strong>Cuidado con los \u00abblanqueadores\u00bb:<\/strong> las gotas vasoconstrictoras hacen que los ojos rojos parezcan blancos durante poco tiempo. Si se usan durante m\u00e1s tiempo, el enrojecimiento puede volver con m\u00e1s fuerza al dejarlas.<\/li>\n\n<li><strong>No frotar:<\/strong> frotarse los ojos puede sobrecargar a\u00fan m\u00e1s una superficie que ya est\u00e1 irritada.<\/li>\n<\/ul>\n\n\n<p class=\"wp-block-paragraph\">Si las molestias vuelven una y otra vez o la causa no est\u00e1 clara, haga examinar sus ojos y p\u00e1rpados. Si se sospecha una alergia, un estudio alergol\u00f3gico puede ayudar.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Ojos rojos: cu\u00e1ndo acudir pronto al oftalm\u00f3logo<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Un dolor intenso, una p\u00e9rdida de agudeza visual, una marcada sensibilidad a la luz o un solo ojo muy enrojecido no encajan ni con una alergia t\u00edpica ni con un ojo seco. En estos casos, haga examinar el ojo pronto por un oftalm\u00f3logo.<\/p>\n\n\n<h2 class=\"wp-block-heading\">C\u00f3mo ayuda Smart Dry Eyes en la alergia y el ojo seco<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Examinamos la superficie ocular, la pel\u00edcula lagrimal y las gl\u00e1ndulas de Meibomio, y preguntamos espec\u00edficamente por el patr\u00f3n temporal, los desencadenantes y los medicamentos. As\u00ed se puede determinar si hay una alergia, un ojo seco o ambos (<a href=\"https:\/\/smartdryeyes.com\/es\/que-se-realiza-en-una-consulta-de-ojo-seco\/\">as\u00ed es el diagn\u00f3stico<\/a>). De ello depende el plan: calmar la alergia donde existe y reforzar la pel\u00edcula lagrimal donde ya no es suficiente.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Preguntas frecuentes sobre alergia y ojo seco<\/h2>\n\n\n<h3 class=\"wp-block-heading\">\u00bfPueden la fiebre del heno y otras alergias causar ojo seco?<\/h3>\n\n\n<p class=\"wp-block-paragraph\">Indirectamente, s\u00ed. La inflamaci\u00f3n al\u00e9rgica sobrecarga la superficie ocular, y algunos antihistam\u00ednicos en comprimidos resecan. Ambas cosas pueden empeorar un ojo seco o hacer que se note por primera vez.<\/p>\n\n\n<h3 class=\"wp-block-heading\">\u00bfQu\u00e9 gotas ayudan a la vez con la alergia y el ojo seco?<\/h3>\n\n\n<p class=\"wp-block-paragraph\">Las l\u00e1grimas artificiales sin conservantes sirven para ambos problemas, porque arrastran los al\u00e9rgenos y apoyan la pel\u00edcula lagrimal. Las gotas antial\u00e9rgicas act\u00faan espec\u00edficamente contra el picor; si se usan a menudo, mejor tambi\u00e9n sin conservantes.<\/p>\n\n\n<h3 class=\"wp-block-heading\">\u00bfPor qu\u00e9 me pican y me arden los ojos a la vez?<\/h3>\n\n\n<p class=\"wp-block-paragraph\">El picor y el ardor pueden aparecer a la vez cuando coinciden una alergia y un ojo seco. Sin embargo, las molestias por s\u00ed solas no muestran de forma fiable cu\u00e1l de las dos predomina.<\/p>\n\n\n<div class=\"wp-block-group has-background is-layout-constrained wp-container-core-group-is-layout-71818893 wp-block-group-is-layout-constrained\" style=\"border-radius:10px;background-color:#eef4f6;padding:28px\">\n<h3 class=\"wp-block-heading\">Descubra la causa de sus ojos secos<\/h3>\n<p class=\"wp-block-paragraph\">Un cuestionario puede darle las primeras pistas.
