Blood flow can be increased by leeches anti-coagulate properties.(Stops blood from clotting) They have been successfully used in the reattachments of fingers.
(According to the apothecaries at Williamsburg, they also increase white blood cells counts to fight infection. So did injesting Mercury. YUM! Love historical medicine!)
But impeded blood flow for 2 years to the retina or brain causes permanent damage that I don’t see how anti-coags can fix now.
Can’t even figure out why a fall down the stairs would cause blindness unless brain damage but MAYBE son trying to gouge his dads eye has something to do with this. That has nothing to do with blood flow. The cornea, which the kid probably, presumptively gouged doesn’t have a blood supply. This doesn’t make sense at all.
The biggest leeches this guy has to deal with is his lawyers.
There are likely other factors involved as well.
“The use of leeches to lessen the rate of blood flow to the eye lessens the production of vitreous humor and thus lessens the pressure inside the eye. So is used as well to reduce the damage of glaucoma.”
“Another area where leech therapy can be beneficial is eye inflammation. Chorioretinitis [an inflammation of the choroid and retina of the eye], conjunctivitis [inflammation of the conjunctiva of one or both eyes], Keratitis [a condition in which the eye’s cornea, the front part of the eye, becomes inflamed] and schleritis [a serious inflammatory disease that affects the white outer coating of the eye, known as the sclera] are just some of eye inflammation disorders.”
