Figures & data

Figure 1 A) Tear break-up time (TBUT) showing breaks in the fluorescein after 1 second; B) the same patient on follow-up visit with TBUT (white arrow) first appearing at 7 seconds.

Figure 2 A) Mean tear break-up time on latanoprost and after switch to travoprost without BAK; B) Mean ocular surface disease index on latanoprost and after switch to travoprost without BAK.

Abbreviations: BAK, benzalkonium chloride; OSDI, ocular surface disease index.
