  • Title: Aspiration cytology of the conjunctival surface.
    Author: Grossniklaus HE, Stulting RD, Gansler T, Aaberg TM.
    Journal: Acta Cytol; 2003; 47(2):239-46. PubMed ID: 12685195.
    Abstract:
    OBJECTIVE: To evaluate a method of obtaining conjunctival cells that utilizes aspiration of the conjunctival surface. STUDY DESIGN: Eighteen eyes from 16 patients with epibulbar lesions underwent aspiration of the conjunctival surface using a tuberculin syringe without a needle. The aspirated cells were prepared by the cytocentrifuge or Millipore filter technique. The lesions were subsequently biopsied, and the cytologic and histologic diagnoses were compared. RESULTS: Diagnoses of the conjunctival lesions, in decreasing order of frequency, were conjunctival intraepithelial neoplasia (dysplasia, carcinoma in situ), squamous cell carcinoma, squamous metaplasia, nevus, lymphoma and inflammation. In this feasibility study, the cytologic diagnosis accurately correlated with the histologic diagnosis in most cases. There were two cases in which the cytologic diagnosis led to the correct histologic diagnosis. CONCLUSION: Aspiration cytology of the conjunctival surface is useful in obtaining diagnostic material and may be used as a guide to where a biopsy should be performed. Limitations include inadequate samples and lack of observer experience.
