Conjunctival Impression Cytology and Tear Film Changes in Sarcoidosis: A Subjective and Objective Diagnosis Study.

Objectives: To evaluate sarcoidosis-induced tear film changes using subjective and objective diagnostic tests, particularly conjunctival impression cytology (IC), and to compare the results with healthy individuals.

Materials And Methods: This study evaluated clinical data collected between January 2019 and January 2021 from 57 right eyes of 57 sarcoidosis patients without ocular involvement (Group 1) and 33 right eyes of 33 healthy individuals with similar demographic characteristics (Group 2). The Schirmer I test, tear break-up time (TBUT), fluorescein staining, and conjunctival IC were all performed as part of the conjunctival and corneal examinations following a thorough ophthalmological examination.
