I was just reading this in the Clark book, while looking for something else:

is caused by parasites.
The eye is a favorite
location for many parasites,
Toxoplasma, and innumerable
others. The eye
has two large bodies of
watery fluid: the aqueous
humor and vitreous
humor, where no blood
traverses to bring in extra
white blood cells when
the need arises. It has its
own protective devices,
like tears, but some
Toxoplasma, have overcome all the body's
defenses and regularly invade the eye if they get into the body
We get Toxoplasma from cats; the infectious stage is in cat
Toxoplasma infection could be the beginning of a lifetime of
eye disease due to weakening of the eyes at an early age.
Toxoplasma also invades the brain, frequently causing a dull
ache or pressure at the back of the head. Trichinella is another
common eye parasite, invading the eye muscles, so that a muscle
is weakened and doesn't allow perfect alignment of the two eyes.
Dogs and cats are the source of these.
There should never be a cat box in the house.
Never let a child near a cat box.
By killing all the large parasites
plus a few bacteria
(Staphylococci, Chlamydias, Neisserias) the eye can become
pain free in a few days. If pain returns, you missed something or
reinfected yourself. Everyone in the family including pets needs
to be treated for all the parasites. No indoor pets should be kept
by a person of low immunity, since infecting yourself daily and
then killing parasites
daily is not a solution.
Herpes of the eye is not a single actor. The true host of this
virus is a larger parasite, possibly a Tapeworm
