In the so-called glass eye (_Amaurosis_), the appearance of the eye is that of a normal one, the optic nerve being in a paralytic state. Opacity of the cornea does, in accordance with the degree and situation of such deposit, produce corresponding deficiency of sight. INVERTED EYELIDS In this diseased condition it is generally the upper eyelid that is turned inwards. If the eyelashes grow inwards, it is called _Trichiasis_. In both conditions it follows that the lashes must be in contact with the globe of the eye. If only a few lashes are growing inwards, they should be pulled out, but, if numerous, this is not a good plan. To cure it, a surgical operation is necessary. EVERTED EYELIDS Like inverted or turned-in eyelid, everted, or turned-out eyelid is not a diseased condition, but the outcome of disease, probably of a weak orbicular muscle. It is the lower eye that is usually affected, and is curable by operation only. TORN EYELIDS Injuries to the eyelids, unless properly treated, are liable to result in permanent unsightliness, or, it may be, affect the sight. Either of the conditions last alluded to can be produced through injury to the eyelids externally, or internally. Unless very slightly torn, it will be better to consult a M.R.C.V.S. FOREIGN BODIES IN THE EYES Minute particles of foreign substances, such as thorns, the outer covering of various seeds, etc., are liable to gain admission into the eyes. If the glume of an oat seed, etc., lodges on the cornea, it may remain adherent, setting up inflammation of it. Blindness is a common result. When the cornea is punctured, it is advisable to have professional advice. After the removal of a foreign body--best done by turning the upper lid outwards and upwards with the fingers--insert a drop or two of castor oil daily for a few days, or as long as seems necessary. Severe injuries to the eyeball are liable to be followed by sympathetic inflammation in the sound eye. BARENESS ROUND MARGINS OF EYES It commonly happens that around the margins, through several causes, the hairy part becomes destitute of hair, giving the dog a very unsightly appearance. In most instances the disease is of an eczematous nature, requiring constitutional treatment for its removal. (_See_ ECZEMA.) As an erythema it is seen in distemper, arising through the acrid discharge from the eyes scalding the surrounding areas. Smear the part with a little Singleton's Golden Eye Ointment, or with a little vaseline, cold cream, or boracic acid ointment. CHAPTER XXV =Injuries and Minor Operations= WOUNDS--OVERGROWN CLAWS--FRACTURES WOUNDS Lacerated and punctured wounds are very common, more especially amongst sporting dogs, and this chiefly owing to the thickets, etc., they have to face during work. Wounds and fractures are not uncommonly associated; if so, the injury is spoken of as compound. The gravity of a dual injury is much greater than where either exists as a single one.
