Abstract

Purpose : To investigate the relationship between noninvasive tear break-up time and ocular parameters of dry eye syndrome

Methods : Medical record of a total of 45 patients with dry eye syndrome were reviewed. Noninvasive keratograph break-up time (NIKBUT) using Oculus® Keratograph 5M and dry eye parameters such as tear break-up time (TBUT), ocular staining score (Sjögren's International Collaboration Clinical Alliance (SICCA) ocular staining score), Schirmer-I score, lipid layer thickness (measured with LipiView®) were obtained. Systemic laboratory data and medication history were also collected. Correlation between the parameters were analyzed by Mann-Whitney test.

Results : 45 patients with mean age of 60.0 ± 13.8 years and female predominance (77.78%) were enrolled. 15.56% of patients were diagnosed with rheumatologic disorder. The median NIKBUT was 8.0 ± 6.0 seconds, and average TBUT was 2.1 ± 1.1 seconds. Median NIKBUT of aqueous deficient type (Schirmer =< 5 mm/5min) dry eye patients were shorter than that of evaporative type (Schirmer > 5 mm/5min) dry eye patients (4.7653, 9.0296 seconds, respectively. p=0.023). Corneal surface parameters such as ocular staining score were not correlated with NIKBUT.

Conclusions : NIKBUT is correlated with the severity of dry eye especially in aqueous deficient type. Although Kertaograph® is used to assess tear film breakdown time, the corneal surface state does not affect the outcome.
