The eye has defense mechanisms against foreign substances, with the conjunctiva often affected by allergies causing conjunctivitis. Diagnosis involves clinical history, cytology, and IgE tests, with symptomatic treatment and prevention strategies.

Area of Science:

  • Ophthalmology
  • Immunology

Context:

  • The eye possesses inherent defense mechanisms against microbial and foreign substance exposure.
  • Anatomical and physiological features of ocular structures (eyelids, tears, conjunctiva, cornea) contribute to ocular resistance.
  • The conjunctiva is frequently impacted, leading to various forms of conjunctivitis, predominantly allergic.

Purpose:

  • To review the defense mechanisms of the eye against foreign substances.
  • To discuss the physiopathology, diagnosis, and management of allergic conjunctivitis.
  • To highlight the role of IgE-mediated reactions in ocular allergies.

Summary:

  • Ocular defense involves specific and non-specific mechanisms, relying on external ocular components.
  • Allergic conjunctivitis, including allergic rhinoconjunctivitis and giant papillary conjunctivitis, is a common manifestation of conjunctival involvement.

  • Diagnosis is based on clinical presentation, conjunctival cytology, and specific IgE evaluation, with treatment focusing on symptomatic relief and preventive measures.

    • Impact:

    • Understanding these mechanisms aids in diagnosing and managing ocular surface diseases.
    • Effective management strategies can improve patient quality of life by alleviating symptoms like pruritus and photophobia.
    • Highlights the importance of considering environmental control and immunotherapy for long-term allergic conjunctivitis management.
