Brief Description
    Inward curling of the eyelid, most commonly the lower lid.

Presenting Signs
    This condition is usually evident before the dog is one year of age. The affected animal can suffer a significant amount of pain due to the eyelashes of the inward-curled lid rubbing on the cornea. Because the eyelids are there to protect the eyes, irritation can also occur due to dust and small objects getting into the eye and damaging its outer surface. Irritation can lead to the dog rubbing at the affected area. Involuntary movements of the eyelid muscles, some discharge and teary eyes can also signal the problem, although if the condition is long standing, the eyes may not produce enough tears. There may be associated corneal ulcers that can lead to eyesight problems, squinting and sensitivity to light. A vision-impaired dog may have trouble recognising everyday objects such as food and water bowls, and people, and may run into furniture and other objects. In addition the difficulty in seeing may make the animal somewhat timid or aggressive in nature.
