Other Signs and SymptomsThe primary efficacy end point of ≥10 mm increase from baseline in the Schirmer test score on day 84 was met for both studies, with a clinically meaningful and significant increase in tear production (16.6% of eyes vs 9.0% of eyes for OTX-101 0.09% and vehicle, respectively, P < 0.0001).13 Similarly, the mean decrease from baseline at day 84 in conjunctival staining was significantly greater for OTX-101 0.09% versus vehicle.13 Subjective improvement in symptoms of dryness and irritation was similar for both treatment groups.
