Hippocrates, the most ancient author we have, has observed in his writings, that the eyes are cured by bleeding, by medicines, the bath, fomentations, and drinking of wine. But he has not explained the proper time for these, and the reasons for their use; in which the principal part of medicine consists. There is also much benefit received from abstinence and clysters. They are sometimes seized with an inflammation; in which they are at once pained and swelled; and there follows a discharge of gum; sometimes more, sometimes less plentiful, or acrid. In such a case, the principal remedies are rest and abstinence. Wherefore, for the first day, the patient ought to lie in a dark place, and even refrain from speaking; to take no food at all; if he can command himself, not so much as water; if he cannot do that, at least as little of it as possible. But if the pains are severe, blood must be taken away, and preferably on the second day; but if the case be urgent, on the first; especially if the veins in the forehead swell, the patient be strong, and there is a redundancy of matter: but if the illness be less severe, it calls for a milder cure. It is not necessary to give a clyster, till the second or third day. But a small inflammation requires neither of these remedies; and it is sufficient to rest and fast. Nevertheless, long fasting is not proper in lippitudes, lest it render the gum more fetid and acrid; but on the second day, some of the gentlest of those things, that generate a thicker phlegm(3), ought to be given, such as sorbile eggs; if the disorder be but slight, pulticula, or bread sopped in milk. On the following days, as much as the inflammation decreases, so much may the quantity of food be increased; but of the same kind; so that above all, nothing salt, or acrid, or extenuating be taken; and nothing be used for drink but water. And with respect to diet, such a regimen is highly necessary.
