=CINDERS AND OTHER FOREIGN BODIES IN THE EYE.=[4]--Foreign bodies are most frequently lodged on the under surface of the upper lid, although the surface of the eyeball and the inner aspect of the lower lid should also be carefully inspected. A drop of a two per cent solution of cocaine will render painless the manipulations. The patient should be directed to continue looking downward, and the lashes and edge of the lid are grasped by the forefinger and thumb of the right hand, while a very small pencil is gently pressed against the upper part of the lid, and the lower part is lifted outward and upward against the pencil so that it is turned inside out. The lid may be kept in this position by a little pressure on the lashes, while the cinder, or whatever foreign body it may be, is removed by gently sweeping it off the mucous membrane with a fold of a soft, clean handkerchief. (See Figs. 6 and 7.) [Illustration: FIG. 6. FIG. 7. REMOVING A FOREIGN BODY FROM THE EYE. In Fig. 6 note how lashes and edge of lid are grasped by forefinger and thumb, also pencil placed against lid; in Fig. 7 lid is shown turned inside out over pencil.] Hot cinders and pieces of metal may become so deeply lodged in the surface of the eye that they cannot be removed by the method recommended, or by using a narrow slip of clean white blotting-paper. All such cases should be very speedily referred to a physician, and the use of needles or other instruments should not be attempted by a layman, lest permanent damage be done to the cornea and opacity result. Such procedures are, of course, appropriate for an oculist, but when it is impossible to secure medical aid for days it can be attempted without much fear, if done carefully, as more harm will result if the offending body is left in place. It is surprising to see what a hole in the surface of the eye will fill up in a few days. If the foreign body has caused a good deal of irritation before its removal, it is best to drop into the eye a solution of boric acid (ten grains to the ounce of water) four times daily.
