Ophthalmologic Comorbidities in Alopecia Areata.

Area of Science:

• Dermatology
• Ophthalmology
• Immunology

Background:

• Alopecia areata (AA) is an autoimmune disease impacting hair follicles.
• Emerging evidence suggests AA may be a systemic condition with potential extra-cutaneous manifestations.
• Immune privilege breakdown is a proposed pathogenic mechanism linking AA to other organs, including the eye.

Purpose of the Study:

• To review the current understanding of the association between alopecia areata and ocular involvement.
• To explore shared pathogenic mechanisms between AA and eye conditions.
• To discuss clinical eye manifestations and management strategies for ocular symptoms in AA patients.

Main Methods:

• Literature review of studies investigating alopecia areata and ophthalmic comorbidities.
• Analysis of proposed pathogenic pathways, including immune privilege.
• Synthesis of reported clinical eye manifestations and their prevalence.

Main Results:

• Several studies report ocular abnormalities in patients with alopecia areata, often appearing at younger ages.
• Shared autoimmune and inflammatory pathways are implicated in the co-occurrence of AA and eye conditions.
• Ocular manifestations can be subclinical or symptomatic, highlighting the need for vigilant screening.

Conclusions:

• Alopecia areata may have significant ocular associations requiring clinical attention.
• Understanding shared mechanisms can guide the diagnosis and management of ophthalmic comorbidities in AA.
• Ophthalmological evaluation should be considered in the comprehensive care of patients with alopecia areata.
