Effect of Blinking on Tear Elimination as Evaluated by Dacryoscintigraphy

To document the change in drainage of tears that occurs with blinking, the authors evaluated 17 lacrimal systems of 12 individuals with dacryoscintigraphy. A significant difference in tear drainage was found by keeping the eyelids closed during the first 2 minutes after drop placement (P < 0.03),...

Zusammenfassung:	To document the change in drainage of tears that occurs with blinking, the authors evaluated 17 lacrimal systems of 12 individuals with dacryoscintigraphy. A significant difference in tear drainage was found by keeping the eyelids closed during the first 2 minutes after drop placement (P < 0.03), but not from 2 to 5 minutes (P > 0.4). Retardation of tear drainage after droplet placement can be achieved by simple eyelid closure for 2 minutes.
