Objective evaluation of experimental ocular irritation.

E Maul, M L Sears

    Investigative Ophthalmology
    |April 1, 1976
    PubMed
    Summary

    Topical nitrogen mustard causes irritation to the eye, affecting pupil response, intraocular pressure, and ocular vessels. Researchers quantified these irritative effects using refractometry and dye measurements.

    Area of Science:

    • Ophthalmology
    • Toxicology

    Background:

    • Nitrogen mustard is a potent vesicant with known irritative properties.
    • Understanding its ocular effects is crucial for managing potential exposures.

    Purpose of the Study:

    • To quantify the irritative effects of topically administered nitrogen mustard on ocular parameters.
    • To establish reproducible methods for evaluating nitrogen mustard-induced ocular irritation.

    Main Methods:

    • Quantified pupil response, intraocular pressure, and aqueous humor protein concentration.
    • Measured conjunctival and iris hyperemia using Evans blue dye after intravenous administration.
    • Determined aqueous humor protein levels via refractometry.

    Main Results:

    • Established reproducible relationships between nitrogen mustard application and measured ocular effects.
    • Demonstrated quantifiable changes in pupil, intraocular pressure, and vascularity.
    • Quantified protein concentration in aqueous humor.

    Conclusions:

    • Developed and validated methods for assessing nitrogen mustard's ocular irritative potential.
    • Provided a quantitative basis for understanding the ocular toxicity of nitrogen mustard.
