Comparative analysis of the decrease of conjunctivochalasis in various studies.

<p>The figure shows the decrease of the degree of conjunctivochalasis compared to that measure at the start of the treatment in previous studies using a liposome eye spray (dotted arrows) compared to our results using an isotonic glycerol and 0.015% hyaluronate-containing artificial tear (solid lines). Numbers above the arrows represent the different studies on a time scale of their duration in months. 1: current results, 2: Höh et al.
