this is my shih tzu her name is ivy she is 15 months old and she was diagnosed with a disease by the name entropion.

Entropion is a common disease of the eyelids in which the lower or upper lids roll inwards. This abnormal conformation of the eyelids is considered an undesirable inherited trait as it typically leads to pain and swelling of the eyes as a result of irritation caused by eyelash and other eyelid hair impingement on the cornea (the outer layer of the eyeball). Corneal ulcers are a common sequel of entropion and may lead to severe pain, vision impairment due to scarring and loss of the integrity of the entire eye, which can lead to enucleation (eyeball removal).
