11th. =The tears must be clear, limpid and confined within the lower
lid.= Any milkiness, flocculency or overflow is indicative of disease.
12th. =The eyelids must be thin, delicate, evenly and uniformly curved
along the borders, and fringed by an abundance of strong, prominent and
well directed lashes.= Puffiness or swelling betrays inflammation,
dropsy, anæmia, parasitism or other disorder, angularity of the upper
lid an internal ophthalmia, and depilation or wrong direction of the
lashes, local disease.
13th. =The eye should respond instantly, by movement, to new objects and
noises, without showing undue irritability or restlessness.= The
intelligent apprehension of the objects will introduce an aspect of
calmness and docility.
DEFECTS, BLEMISHES AND ABNORMALITIES OF THE HORSE’S EYE.
Some of these may be present in the absence of actual disease, and yet
prove so objectionable that they disqualify the animal for any use, in
which style or æsthetic appearance is demanded. Among such sources of
disqualification may be noted:
1st. =The small eye.= One or both eyes may appear small because of
internal pain and retraction within their sockets, or from actual
atrophy or contraction of the eyeball, the result of deep seated
disease, or the organ may be congenitally small, and deep seated in the
orbit, and the thick tardy eyelids may have a narrow opening through
which they can only be partially seen. This last condition usually
implies a dull lymphatic constitution, low breeding and a lack of
intelligence, docility and vigor.
2d. =The semi-closed eye with thick, coarse, sluggish lids.= In this
case the bulb may be not unduly small, yet as it is not freely exposed
it conveys the same general expression to the observer. Like the small
eye it indicates low breeding, lack of intelligence or docility and
often stubbornness or even vice.
3d. =The convex eye.= In this the transparent cornea describes the arc
of an unduly small circle, suggesting a conical form and projecting
unduly beyond the margins of the lids. It implies imperfect vision,
myopia, and, it is alleged, low breeding and lack of alertness.
4th. =The sunken eye.= This has been already referred to under =the
small eye=. The eyelids are usually flaccid, the upper being drawn in by
its levator so as to form an angle, and the edges of the orbit are
somewhat prominent. It is seen in old, worn out animals, which have lost
the pads of fat in the depth of the orbit, and more commonly in animals
that have suffered several attacks of recurrent ophthalmia.
5th. =The projecting eye.= In this case the lids are unduly contracted
and the eye protrudes between them so as to show a large amount of
sclerotic around the transparent cornea. This may be due to nervous
strain and suffering but, however produced it is decidedly unsightly and
objectionable.
