Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Mean Visualization Score at Post-Instillation from Pre-Instillation
Time Frame: Day 0
A video image of the posterior segment structures of the eye was taken before instillation of the test product and after. An independent masked reader evaluated the images and graded the degree of visualization on a 5-point scale ranging from 1 to 4 and anchored at the ends by "Not Visible (0)" and "Clearly Delineated (4)." The mean difference was calculated, and a higher number indicated increased visibility.
