But when compound medicines are not to be had, both honey and wine mitigates an asperity in the angles. These and a dry lippitude too are relieved by an application of bread, softened with wine, over the eyes. For since there is generally a humour, which exasperates sometimes the eye itself, sometimes the angles, or eyelids; by this application, if any humour is discharged, it is drawn away, and if it happens to be lodged near, is repelled. [Sidenote: _Of a dimness of the eyes._] A dimness comes upon the eyes, sometimes from a lippitude, at other times even without that, from old age, or weakness. If the disorder proceeds from the relics of a lippitude, the collyrium called asclepias is serviceable. Likewise that, which is composed of crocomagma. The collyrium which is called diacrocou[GD] is composed peculiarly for this. It contains of pepper p. i. *. Cilician saffron, poppy tears, ceruss, each p. ii. *. psoricum, gum, each p. iv. *. [GD] διὰ κρόκου. But if it arises from old age, or weakness, it may be proper to anoint with the best honey, and cyprine and old oil. But it is most expedient to mix together one part of balsam, and two of old, or cyprine oil, and three parts of the most pungent honey. The medicines prescribed above for a dimness _from a lippitude_, and those mentioned before for diminishing cicatrices, are useful in this case too. Whoever is troubled with a dimness must walk much, use exercise, frequent bathing, at which time the whole body must be rubbed, but principally the head, with iris ointment till it sweat; after that it must be veiled, and not uncovered, till after he has got home, and the sweat and heat have ceased. Then he must keep to an acrid and extenuating diet; and after the interval of some days use a gargarism of mustard. [Sidenote: _Of a cataract._] A suffusion also, which the Greeks call hypochysis[GE], sometimes obstructs the pupil of the eye, where vision is performed. If this disorder be inveterate, it requires an operation to remove it. At the beginning sometimes it is discussed by certain methods adapted to the case. It is expedient to bleed in the forehead, or nose; to cauterize the veins in the temples; by the use of gargarisms to evacuate phlegm; to use fumigations; to anoint the eyes with acrid medicines. The best diet is such as extenuates phlegm. [GE] ὑπόχυσις. [Sidenote: _A palsy of the eyes._] Nor is a palsy of the eyes (which the Greeks call paralysis) to be cured by any different diet, or different medicines, so that it is needless to do more than describe the distemper. It happens then sometimes in one eye, sometimes in both, either from a blow, or from an epilepsy, or spasms, where the eye itself is strongly convulsed, so that it can neither be directed to any particular object, nor be kept fixed; but moves to and fro involuntarily; and therefore cannot see any thing distinctly.
