    Area of Science:

    • Ophthalmology
    • Cell Biology
    • Histology

    Background:

    • Conjunctival goblet cells are crucial for ocular surface health.
    • Assessing goblet cell morphology and density is important for diagnosing various eye conditions.
    • Existing biopsy methods can be invasive and uncomfortable for patients.

    Purpose of the Study:

    • To develop and evaluate a minimally invasive technique for conjunctival goblet cell biopsy.
    • To assess the feasibility of using Millipore filters for sample collection.
    • To determine if the procedure is comfortable for patients.

    Main Methods:

    • A Millipore filter was pressed onto the conjunctival surface of the eye.
    • The filter was stained using Periodic Acid-Schiff (PAS) and hematoxylin.

  • Samples were cleared with oil and examined under a microscope.

    • Main Results:

    • The technique successfully collected either mucous spots indicative of goblet cell openings or epithelial cell layers containing goblet cells.
    • Microscopic examination revealed goblet cell structures.
    • The procedure was performed on unanesthetized eyes without causing discomfort.

    Conclusions:

    • Millipore filter biopsy is a viable, non-invasive method for obtaining conjunctival goblet cells.
    • This technique offers a comfortable and effective approach for ocular surface evaluation.
    • The method facilitates histological assessment of goblet cell status in ophthalmic research and diagnostics.
