Outcome Measures

Primary Outcomes (3)

  • Quality of life evaluated by the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) Spanish version for Mexico in patients with Allergic Conjunctivitis treated with sublingual allergen immunotherapy.

    To evaluate the quality of life in patients with Allergic Conjunctivitis treated with sublingual allergen immunotherapy using the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) Spanish version for Mexico. This questionnaire features 28 items grouped in 7 domains: activities, sleep, other symptoms, practical problems, nasal symptoms, eye symptoms, emotional. For each item, the minimum score is 0 and the maximum score is 6. After the questionnaire is completed, a mean score is calculated. A higher overall score indicates a poorer quality of life.

    Before Sublingual Immunotherapy

  • Quality of life in patients with Allergic Conjunctivitis treated with sublingual allergen immunotherapy evaluated using the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) Spanish version for Mexico.

    To evaluate the quality of life in patients with Allergic Conjunctivitis during 6 months of sublingual allergen immunotherapy using the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) Spanish version for Mexico. This questionnaire features 28 items grouped in 7 domains: activities, sleep, other symptoms, practical problems, nasal symptoms, eye symptoms, emotional. For each item, the minimum score is 0 and the maximum score is 6. After the questionnaire is completed, a mean score is calculated. A higher overall score indicates a poorer quality of life.

    From enrollment to the end of the 6th month of Allergen Immunotherapy treatment

  • Quality of life in patients with Allergic Conjunctivitis treated with sublingual allergen immunotherapy using Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) Spanish version for Mexico.

    To evaluate quality of life in patients with Allergic Conjunctivitis after completing allergen-specific sublingual immunotherapy using the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) Spanish version for Mexico. This questionnaire features 28 items grouped in 7 domains: activities, sleep, other symptoms, practical problems, nasal symptoms, eye symptoms, emotional. For each item, the minimum score is 0 and the maximum score is 6. After the questionnaire is completed, a mean score is calculated. A higher overall score indicates a poorer quality of life.

    From enrollment until 3 years of treatment with sublingual immunotherapy
