Tear clearance measurement in patients with dry eye syndrome using quantitative lacrimal scintigraphy.

Objective: The aim of this study was to evaluate the tear clearance in patients with dry eye syndrome using quantitative lacrimal scintigraphy.

Materials And Methods: We investigated 21 patients (42 eyes; 18 women, 3 men; mean age, 63.19 +/- 13.

Silicone versus collagen plugs for treating dry eye: results of a prospective randomized trial including lacrimal scintigraphy.

Purpose: To compare the short-term efficacy of collagen and silicone plugs for treating dry eye using quantitative lacrimal scintigraphy.

Design: Prospective randomized clinical trial.

Methods: In this institutional study, 24 dry eye patients were evaluated in two groups: group I (n = 22 eyes) received collagen plugs and group II (n = 26 eyes) received silicone plugs.
