    Summary

    The brush technique is superior for collecting corneal epithelial cells for cytologic evaluation. This method provides better cell yield and preservation compared to cotton swabs or spatulas in rabbit eyes.

    Area of Science:

    • Ophthalmology
    • Cytopathology

    Background:

    • Corneal cytology is crucial for diagnosing ocular surface diseases.
    • Effective sample collection is essential for accurate cytologic interpretation.

    Purpose of the Study:

    • To compare the efficacy of brush, cotton swab, and spatula techniques for obtaining corneal smears.
    • To evaluate the cytomorphologic quality of samples from different collection methods.

    Main Methods:

    • Corneal smears were obtained from 48 rabbits using brush, cotton swab, and spatula techniques.
    • Cytomorphologic features of the collected cells were analyzed.

    Main Results:

    • The brush technique yielded numerous corneal epithelial cells with good spread and minimal overlapping.
    • Samples from cotton swab and spatula methods showed inadequate cell numbers and poor preservation.
    • Brush-prepared smears were satisfactory for cytologic evaluation.

    Conclusions:

    • The brush method is the most effective technique for obtaining corneal epithelial cells for cytologic analysis.
    • Corneal cytology using the brush method is practical for clinical applications.
