Orbital fine-needle aspiration biopsy.

J S Kennerdell, T L Slamovits, A Dekker

    American Journal of Ophthalmology

    Summary

    Fine-needle aspiration (FNA) is an effective orbital diagnostic technique, successfully identifying lesions in 125 of 156 patients. This method aids in diagnosing metastatic carcinoma, inflammatory, and lymphoid lesions.

    Area of Science:

    • Ophthalmology
    • Cytopathology

    Background:

    • Orbital lesions require accurate diagnosis for effective management.
    • Fine-needle aspiration (FNA) is a minimally invasive technique for cytologic evaluation.

    Purpose of the Study:

    • To evaluate the efficacy of fine-needle aspiration (FNA) as a primary diagnostic tool for orbital lesions.
    • To identify common orbital lesions diagnosed via FNA.

    Main Methods:

    • Fine-needle aspiration (FNA) was performed on 156 patients using a 20-mm syringe and a 22-gauge needle.
    • Aspirates were smeared on slides, fixed with alcohol, and cytologically analyzed.
    • Specific techniques, including to-and-fro movements with minimal angulation, were employed.

    Main Results:

    • Cytologic identification was positive in 125 out of 156 cases (80.1% success rate).
    • Commonly diagnosed lesions included metastatic carcinoma, inflammatory conditions, and lymphoid lesions.
    • Diagnostic success was limited in fibrous tumors, orbital apex lesions, and inadequate lymphocytic specimens.

    Conclusions:

    • Fine-needle aspiration (FNA) is a valuable primary diagnostic technique for orbital lesions.
    • FNA provides crucial cytologic information for a range of orbital pathologies.
    • Challenges exist for specific lesion types, necessitating consideration of alternative diagnostic approaches.
