Jack -- According to Ulrich's, Optometry & visual performance is:

Formed by the merger of (1990-2013): Journal of Behavioral Optometry (United States) (1045-8395)
                         (1970-2013): Optometry and Vision Development (United States) (1557-4113)

So unless there is evidence to the contrary from some other source (the issues, the website, publisher communication), I'd like to suggest this is a merger, which means:

* 785 needs to be added to #2026890
* 2nd indicator values need to be changed on #6120936 & 816655991

Hope this helps.  --Steve
