Additional secondary endpoints
Color vision
DILATION, SECONDARY
Other secondary endpoints included the change from baseline to month 12 in the following measures: BCVA, total area of preserved AF, area of preserved ellipsoid zone, microperimetry, contrast sensitivity score, Color Vision Total Error score, reading speed and VFQ-25 score. Change of BCVA from baseline at months 4 and 8 were also secondary endpoints, but the results were not included in this report. Fundus AF was performed to evaluate the changes in the area of viable retinal tissue. Contrast sensitivity was measured before pupil dilation using a Pelli-Robson chart. Color vision was tested separately before pupil dilation. The International Reading Speed Texts (IReST) was used to evaluate reading speed. Self-reported vision-targeted health status responses (individual, subscale and overall composite scores) were obtained using the VFQ-25 questionnaire.
