Ok. I took a screen shot off that spot in the video and pasted it into a document and then used photo tools to brighten and adjust the image. You can barely see that there is potentially the whites of his eyes in there, but they are not bright and may be quite red as they are not reflective or visible as they should be.

But, what I can see for sure is this:

~His left eye orbit is lower on his cheek than his right eye.

~His left eye's iris is very enlarged, unusually and abnormally so - and is either completely dilated or gone black.

~His right eye's iris appears normal size and also appears black.

This is not normal. What can it mean?
