A novel conjunctival brush, adapted from cervical cytology tools, efficiently collects eye surface cells. This noninvasive brushing cytology technique provides valuable diagnostic information for various conjunctival conditions.

Area of Science:

  • Ophthalmology
  • Cytopathology

Background:

  • Conjunctival cell collection is crucial for diagnosing ocular surface diseases.
  • Existing methods may have limitations in efficiency or invasiveness.

Purpose of the Study:

  • To develop and evaluate a modified brush for efficient conjunctival cell collection.
  • To assess the diagnostic utility of conjunctival brushing cytology.

Main Methods:

  • A modified cervical cytology brush (conjunctival brush) with nylon bristles was developed.
  • Cells were collected from the temporal bulbar conjunctiva and prepared using filter methods.
  • Papanicolaou staining was used for cytological analysis.

Main Results:

  • The conjunctival brush yielded adequately cellular samples.

  • Three main cell types were identified: epithelial, small rounded, and goblet cells.
  • Distinct cellular changes were observed in dry-eye, post-irradiation, and post-operative patients, including keratinization and elongated cells.

    • Conclusions:

    • Conjunctival brushing cytology is a minimally invasive technique.
    • It effectively collects cells for Papanicolaou staining and analysis.
    • This method offers valuable insights into conjunctival health and disease states.
