Such as a rule are the lesions which are apt to occur around the eyeball in the angles or eyelids. But in the eyeball itself the outer tunic is sometimes raised, by the rupture or by the relaxation of certain membranes inside, and its shape becomes like a grape: the Greeks therefore call the lesion staphyloma. There are two modes of treatment. In one a needle carrying two threads is passed through the middle of its base, and first the two ends of the upper thread, and then those of the lower, are knotted, and these gradually cut through and so excise the staphyloma. In the other method, a piece about the size of a lentil is cut off from its tip, then oxide or carbonate of zinc is dusted on. After either method, wool soaked in white of egg is applied; subsequently the eye is steamed, and then anointed with soothing medicaments.

Again, small hard tumours in the white of the eyeball are called clavi, from a resemblance in shape to nailheads. These it is best to transfix with a needle at their base, and to cut away underneath the needle; then to anoint with soothing medicaments.
