Eye-cosmetic-induced conjunctival pigmentation.

E V Platia, R G Michels, W R Green

    Annals of Ophthalmology
    |April 1, 1978
    PubMed
    Summary

    Eyelid cosmetics can cause conjunctival pigmentation due to deposited ferritin, iron oxide, and carbon particles. This study examines the microscopic evidence of cosmetic-induced pigment deposition in the eye.

    Area of Science:

    • Ophthalmology
    • Histopathology
    • Toxicology

    Background:

    • Conjunctival pigmentation can arise from various endogenous and exogenous sources.
    • Eyelid cosmetics are frequently used, raising questions about potential ocular side effects.
    • Understanding pigment deposition is crucial for diagnosing and managing ocular conditions.

    Observation:

    • A light and electron microscopic examination was performed on conjunctival tissue.
    • The study focused on a 27-year-old woman with a history of eyelid cosmetic use.
    • Pigment deposits were observed within the conjunctival stroma.

    Findings:

    • The deposited material was identified as ferritin particles.
    • Iron oxide and carbon were also likely components of the deposited pigment.
    • This suggests a direct link between eyelid cosmetic use and conjunctival pigment deposition.

    Implications:

    • Cosmetic use can lead to exogenous pigment accumulation in the conjunctiva.
    • Ferritin, iron oxide, and carbon are potential components of cosmetic-induced conjunctival pigmentation.
    • Further research is warranted to understand the long-term effects and prevalence of this phenomenon.
