Evaluation of Dry Eye Using Anterior Segment Optical Coherence Tomography in Patients With End-Stage Renal Disease Undergoing Hemodialysis

Abstract

The aim of the present study was to evaluate dry eye parameters with conventional tests and tear meniscus with Anterior Segment Optical Coherence Tomography (AS-OCT) in patients with end-stage renal disease (ESRD). Thirty-eight ESRD patients undergoing hemodialysis, and 40 healthy individuals were enrolled. An ocular surface disease index questionnaire (OSDI) was administered. Before conventional dry eye tests, tear meniscus were evaluated using AS-OCT. After a complete ocular examination, Schirmer and break-up time (BUT) tests were performed and probable corneal staining was investigated. Schirmer test and BUT values were significantly lower in ESRD patients (P<0.05). OSDI scores and corneal staining scores were significantly higher in ESRD patients (P<0.05). Tear meniscus height, tear meniscus depth, and tear meniscus area, which were obtained by AS-OCT were significantly lower in patients with ESRD (P<0.05). Tear meniscus evaluation using AS-OCT is an effective and non-invasive method to assess tear meniscus in patients with ESRD. Patients with ESRD undergoing hemodialysis should obtain regular ophthalmic examination, especially for dry eye.
