Enrojecimiento, picaz\u00f3n, lagrimeo o sensaci\u00f3n de arenilla en los ojos suelen atribuirse a un malestar pasajero. Sin embargo, estos s\u00edntomas pueden corresponder a dos afecciones distintas: la conjuntivitis infecciosa y la alergia ocular.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Aunque comparten manifestaciones similares, sus causas, riesgos y tratamientos no son los mismos. Especialistas de la <strong>Cleveland Clinic<\/strong> se\u00f1alan que reconocer las diferencias a tiempo permite evitar complicaciones, reducir el riesgo de contagio y proteger la salud visual.<\/span><\/p>\n<h3 class=\"wp-block-heading\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Qu\u00e9 es la conjuntivitis y qu\u00e9 es la alergia ocular<\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">La conjuntivitis es la <strong>inflamaci\u00f3n <\/strong>de la conjuntiva, la membrana transparente que recubre la parte blanca del ojo y el interior de los p\u00e1rpados. Puede estar causada por virus o bacterias y, en esos casos, se considera infecciosa.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">La conjuntivitis al\u00e9rgica, en cambio, aparece cuando los ojos reaccionan ante al\u00e9rgenos como el polen, el polvo, la caspa de animales o ciertos productos irritantes. No est\u00e1 provocada por microorganismos y no se transmite de una persona a otra.<\/span><\/p>\n<h3 class=\"wp-block-heading\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Diferencias en los s\u00edntomas y el contagio<\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">El doctor Robert Engel, optometrista de la Cleveland Clinic, explica que la conjuntivitis infecciosa es altamente contagiosa. Puede propagarse al tocar superficies contaminadas y luego llevarse las manos a los ojos, o por contacto directo con una persona infectada.<\/span><\/p>\n<figure class=\"wp-block-image size-full\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1861910 lazy w-100 h-auto entered loaded\" src=\"https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular.jpeg\" sizes=\"(max-width: 992px) 100vw, 992px\" srcset=\"https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular.jpeg 992w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-300x168.jpeg 300w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-768x430.jpeg 768w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-150x84.jpeg 150w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-600x336.jpeg 600w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-900x504.jpeg 900w\" alt=\"\" width=\"992\" height=\"556\" data-src=\"https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular.jpeg\" data-srcset=\"https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular.jpeg 992w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-300x168.jpeg 300w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-768x430.jpeg 768w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-150x84.jpeg 150w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-600x336.jpeg 600w, https:\/\/eldia.com.do\/wp-content\/uploads\/2026\/02\/Alergia-ocular-900x504.jpeg 900w\" data-ll-status=\"loaded\" \/><\/span>\n<figcaption class=\"wp-element-caption\"><span style=\"font-size: 14pt;\">La conjuntivitis infecciosa suele comenzar en un ojo y es altamente contagiosa, mientras que la alergia ocular afecta a ambos ojos simult\u00e1neamente y no se transmite.<\/span><\/figcaption>\n<\/figure>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">En contraste, la alergia ocular no es <strong>contagiosa <\/strong>y suele presentarse en personas con antecedentes al\u00e9rgicos, especialmente en \u00e9pocas de alta concentraci\u00f3n de polen o tras la exposici\u00f3n a sustancias irritantes.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>Existen algunas se\u00f1ales que ayudan a distinguirlas:<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Inicio de los s\u00edntomas: la conjuntivitis infecciosa suele comenzar en un ojo y despu\u00e9s extenderse al otro. La alergia ocular, por lo general, afecta a ambos ojos desde el principio.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Tipo de picaz\u00f3n: en la alergia el <strong>picor <\/strong>suele ser intenso y persistente. En la conjuntivitis infecciosa puede haber molestias y escozor, pero el picor suele ser menos marcado.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Secreci\u00f3n: una secreci\u00f3n clara y acuosa puede aparecer tanto en alergias como en infecciones virales. En cambio, la secreci\u00f3n espesa y amarillenta suele asociarse a infecciones bacterianas.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Hinchaz\u00f3n: la inflamaci\u00f3n notable de la conjuntiva es m\u00e1s frecuente en <strong>cuadros al\u00e9rgicos<\/strong>.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Ambas afecciones pueden provocar enrojecimiento y sensaci\u00f3n de cuerpo extra\u00f1o, lo que explica la confusi\u00f3n habitual entre ellas.<\/span><\/p>\n<h3 class=\"wp-block-heading\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Tratamiento y cuidados recomendados<\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">En el caso de la conjuntivitis infecciosa, muchos cuadros virales mejoran por s\u00ed solos en un plazo de cinco a diez d\u00edas. Las <strong>l\u00e1grimas artificiales<\/strong> pueden aliviar las molestias, pero si los s\u00edntomas empeoran o no mejoran tras dos d\u00edas, es recomendable consultar con un especialista para valorar el uso de colirios espec\u00edficos.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Para la conjuntivitis al\u00e9rgica, el primer paso es evitar el contacto con el al\u00e9rgeno desencadenante. Los colirios antihistam\u00ednicos pueden ayudar a reducir el picor y el enrojecimiento. En casos persistentes, el m\u00e9dico puede indicar gotas oft\u00e1lmicas con esteroides bajo supervisi\u00f3n profesional.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Las compresas fr\u00edas y las l\u00e1grimas artificiales sin conservantes pueden ofrecer alivio temporal en ambos casos. No obstante, los especialistas advierten que los colirios descongestionantes no deben utilizarse durante m\u00e1s de cinco d\u00edas seguidos, ya que su uso prolongado puede empeorar los s\u00edntomas.<\/span><\/p>\n<h3 class=\"wp-block-heading\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Cu\u00e1ndo consultar de inmediato<\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">La sensibilidad intensa a la luz, el dolor ocular significativo o la disminuci\u00f3n de la visi\u00f3n no son s\u00edntomas habituales de una conjuntivitis simple o de una alergia leve. Ante cualquiera de estas se\u00f1ales, se recomienda acudir de inmediato al oftalm\u00f3logo, ya que podr\u00edan indicar afecciones m\u00e1s graves.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Los expertos subrayan que una evaluaci\u00f3n temprana facilita un tratamiento adecuado y una recuperaci\u00f3n m\u00e1s r\u00e1pida. Ante la duda, evitar la automedicaci\u00f3n y buscar orientaci\u00f3n profesional es la mejor forma de cuidar la salud visual.<\/span><\/p>\n\n\n<div class=\"wp-block-group\"><div
