Disorder - EctropionOrgan Systems Involved
The eyelids are turned outward, and do not rest against the eyeball, so that parts of the eye are exposed and unprotected.
The eyelids serve to protect and clean the surface of the eye. Clinical signs of ectropion may vary with severity and some animals do not show any at all. The condition usually worsens at the end of the day and following exercise, when the eyes have been exposed to wind, dust etc. Animals may exhibit an abnormal flow of tears down the face and a discharge containing mucus and pus. There may be inflammation of the eye and the inside of the eyelid, and an increased number of blood vessels in the exposed inner eyelid. Some animals will develop long term or recurrent conjunctivitis as a result of exposure and inability to clear debris and mucus from the eye. Rarely, this condition can result in ulceration and pigmentation of the cornea (the transparent outer surface of the eyeball) and can potentially affect eyesight.
