I don't think I can be of much help. Maternal/Child health is my field of expertise. Here's an excerpt from
The Merck Manual than might be of help:
"Seeing floaters (spots) before one or both eyes is a frequent adult complaint. Floaters are usually most noticeable against a white homogeneous background and seem to move slowly when the eye is still. Floaters maintain their relative position in the visual field with eye movement. They result from contraction of the vitreous gel and its separation from the surface of the retina (posterior vitreous detachment). This leads to macroscopic opaque aggregates of vitreous fibers, which can be seen floating in the vitreous. Since the vitreous gel is denser where it attaches to the optic nerve, floaters are usually more apparent in this area. Although floaters usually are without significance, in a few patients they may indicate a tear in the retina. They are more prevalent in highly myopic and older persons and tend to become less noticeable with time."
Good luck!
