|First view the animal directly. Make sure both eyes are of equal size and
prominence. Watch for any evidence
of visual impairment. Assess the horse’s expression.
Look for any signs of asymmetry or irregularity of the
eyelids or the globe. Also note any abnormalities in the
skin around the eyes and any facial
horse should be examined for any ocular discharge.
duct opening can be seen near the mucocutaneous junction inside the
nostril. It is especially
important to check whether this is present in young animals presented with a
complaint of excessive tearing; congenital malformation can result in an
imperforate duct. In older animals the duct may become obstructed
even if a puncta is visible.
|Color of the conjunctiva and also more detail of
the lids can be examined by carefully everting the eyelid.
||Intraocular pressure can be
grossly examined by lightly palpating the globe through the eyelid.
The index and middle finger are gently applied to the globe and the
fingers are moved back and forth so as to indent and feel the change in
pressure in the eye. Obviously,
this will only detect a gross
decrease or increase in intraocular pressure.
The opposite eye should always be compared. Obviously, this
test should never be performed on an eye that is very painful or in danger
