I am not sure it does. Efferent connections to the retina are not so well known.
I'll have to check it up.
Off-hand, I would say that it is well known that later centers in the
pathway send efferent connections to earlier ones as far as the
thalamus, but not to the retina. On the other hand, it may be speculated
that the eye movements during REM sleep might induce some kind of
activity in the retina by mechanical means. The functional significance
of such stimulation would be doubtful.
I might check up later.
