A little vitreous humor

Vitreous humor lines the backs of our eyeballs. We are born with a full supply of the stuff, but as we age, it begins to dry out or evaporate or some damn thing—the roly-poly ophthalmologist shining a beam into my eye wasn’t overly explicit on this point. 

Sometimes the stuff detaches and comes to the front of the eye. It can be discolored, particularly if the detached part used to be close to the optic nerve. The result is a vitreous floater, which is like having a microscopic slide of an insect’s leg in front of one of your eyes. One eye sees the world. The other eye sees the world but also sees the microscopic slide of the insect’s leg. 

At times the “slide” moves around. At night there can also be white flashes that go off every two minutes or so—spaced just far enough apart to work like Chinese water torture.

The roly-poly ophthalmologist told me it’s caused by aging, it happens to most people eventually, and there’s nothing doctors can do about it, other than monitor the situation to make sure it doesn’t get worse—because if it gets worse, that could be a sign of something more serious.

The roly-poly ophthalmologist at the space-age eye hospital told me that over time I would see less of it, or learn to ignore it, or something—he wasn’t overly explicit on this point.

I’m to go back and see him again in a month.
