Exploring the natural history of dry eye disease development
Time/Date: 3:30pm - 4:30pm Monday 11 March 2019
Location: K-F10-M10 Lecture Theatre Chemical Science Building (M10)
This presentation explores dry eye disease development by comparing the ocular surface and tear film characteristics of the anatomically distinct Asian and Caucasian eye throughout life. Three methodologically homogenous, age and environmentally-controlled, cross-sectional studies comprising Asian and Caucasian populations ranging from 5 to 90 years of age were pooled for analysis. The earliest ethnic disparities detected were significantly higher degrees of incomplete blinking and lid wiper epitheliopathy in the young Asian eye (under 18 years of age), that may be attributable to the anatomical predisposition towards increased eyelid tension. These differences persisted in the older age groups and were compounded by an inter-ethnic divergence in the level of meibomian gland dropout in the young adult population and, further, by differences in symptoms, tear film clinical characteristics, meibomian gland function and disease likelihood (based on TFOS DEWS II criteria) in the middle adult population. Disparities in corneal and conjunctival staining were limited to the older adult population. The results suggest a critical role for blinking in dry eye development through loss of meibomian gland function. Comparable and physiologically adequate tear meniscus heights noted across all age groups support the clinical observation that an evaporative rather than aqueous deficient mechanism appears to be the major player in the natural history of dry eye development.
