Purpose: To demonstrate the ultrastructural appearance of the conjunctival surface epithelium in patients with Sjögren's syndrome (SS) compared with normal subjects.

Methods: Conjunctival tissue specimens from seven normal subjects and eight patients with SS were obtained by bulbar conjunctival biopsy and examined by transmission electron microscopy.

Results: The average number of microvilli per 8.
