Common Guinea Pig Eye Problems

Guinea pig eyes are susceptible to many eye problems such as cataracts, corneal ulcers, conjunctivitis, kerato-conjunctivitis, Tumors, entropion, ectropion, and tear duct infections.

Some guinea pigs are born with malformed eyes, which are referred to as congenital ocular disorders.

Corneal ulcers

This is a common condition that guinea pigs encounter. An injury or trauma to the cornea causes a corneal ulcer. Trauma can occur as a result of playing and fighting with other pets, or as a result of hay or dry grass with sharp edges.

If left untreated, a corneal ulcer might lead to complete blindness. So, consult a vet as soon as possible.
