Immunosuppression and eye disease. First Vail lecture.

D G Cogan

    American Journal of Ophthalmology
    |June 1, 1977
    PubMed
    Summary

    Immunologic deficiencies increase the risk of various viral, fungal, and protozoal eye diseases. These infections, including cytomegalovirus and toxoplasmosis, can cause necrotizing retinopathy and vision loss.

    Area of Science:

    • Ophthalmology
    • Infectious Diseases
    • Immunology

    Background:

    • Immunologic deficiencies are linked to several opportunistic ocular infections.
    • Viral, fungal, and protozoal pathogens can cause severe retinal damage.

    Purpose of the Study:

    • To review the spectrum of ocular diseases associated with immunologic deficiencies.
    • To describe the clinical characteristics and pathogenesis of these infections.

    Main Methods:

    • Literature review of viral, fungal, and protozoal ocular infections in immunocompromised patients.
    • Analysis of disease presentation, retinal involvement, and potential mechanisms.

    Main Results:

    • Viral infections (cytomegalovirus, herpes simplex/zoster, measles) cause necrotizing retinopathy.
    • Fungal infections (Candida, Aspergillus) present as choroidal lesions with secondary retinal involvement.
    • Protozoal toxoplasmosis is activated by immunosuppression, leading to necrotizing retinopathy.

    Conclusions:

    • Ocular infections in immunocompromised individuals present with distinct patterns of retinal and choroidal disease.
    • Understanding these patterns is crucial for diagnosis and management.
    • The role of autoimmunity in ocular disease pathogenesis requires further investigation.
