— Using clinical data, normative values of accommodative vergence and related tests are presented and compared to previously published data. The results are highly variable. The ‘phorias are the most variable tests while positive relative accommodation (PRA) and the recovery values on the whole have moderate variability. Negative relative accommodation (NRA), pupil size, break and blur findings on average exhibit low variation.
