1. The defect thereof, which if caused, can∣not be cured, but the deformity may be helped by one that is facti∣tious, as may be seen in Paraeus.
2. The atrophy of the eye, when all the parts thereof are diminished, which is caused, by too much evacuation or exsiccation, by weeping, sharp humours, watching, feavers, and obstruction; it's cured by humecters, and womans milk, &c.
3. The ecpiesma, or falling out thereof, which is caused, by external violence, resolution of the muscles and nerves, wounds of the annate tunicle, or tumours; it's cured, V. P. by reposition, ligature, cupping-glasses in the neck, repellents, roborants, and defensives; if from resolution, by apophlegmatismes, odorates, astringents, and section if need, with traumaticks.
4. Stra∣bisme, which is when the ball declineth from the midle, so that more white appeareth in one part of the eye, than in the other, therefore such looke on one side, and it's caused by conformation, custom, or convulsion and resolution of the muscles; it's cured in infants by putting somewhat before the eyes, with a hole in it, in the opposite part, and placing the light on the other side that the infant may turne his eyes that way: If it be from a spasme or reso∣lution, it's so to be cured.
