Comparing the Vitreous Floaters Functional Questionnaire to the VFQ-25 in Vision Degrading Myodesopsia from Vitreous Floaters

In patients with vitreous floaters, the VFFQ-23 correlated with CS and QUS. VFFQ-23 was a better predictor of patient management choice (OBS or LRV) and was more sensitive to post-operative improvement than VFQ-25. VFFQ-23 superiority to VFQ-25 was confirmed by DCA. Thus, VFFQ-23 may be more useful in assessing the subjective impact of floaters on visual quality-of-life, in screening/triage, and as an outcome measure of current and future therapies for VDM.
