Species: Dog
Condition: Macroblepharon
Organ System: Nervous/sensory
Also called eryblepharon, macroblepharon is characterized by an abnormally large opening of the eyelids resulting in reduced eye protection. Affected dogs are more prone to corneal ulceration. The condition is an important predisposing factor to many diseases affecting the eyes. In brachycephalic breeds, the problem is associated with the protrusion of the globe (exopthalmus). Severe cases are usually linked to entropion of the upper and lower eyelids, giving rise to the term “diamond eye”. The problem results in the inability to accomplish the blink mechanism (lagophthalmos), resulting in drying and exposure keratitis. Prophylaxis involves administration of artificial tears or surgery to shorten the malcopalpebral fissure. The latter procedure is considered a permanent solution.
