No the tests: you mention are electrophysiology tests which measure different eye issues including pupillography (light sensitivity) etc. There are NO Correlations I am aware of with Seasonal Affective Disorder PER SE (HOWEVER research using these tools is ONGOING!!!!!!!! You might ask your OPTHAMOLOGIST for some references! Hope this helps\ Dr Z

Seasonal Affective Disorder appears to be directly related to low Vitamin D....... Human and animal studies show that about 5,000 i.u.'s are needed each day. We used to get about that much from one day of sun/UV exposure day. No one gets that anymore. So, we need to take 5,000/day, and maybe even more in the 6 months of winter.
