My guinea pig has crusty eyes for years, now bald spots. What's wrong?

Pet's info: Bird | Unknown - Bird | Male | unneutered | 2 years and 11 months old

why does my guinea pig have crusty eyes? he isn't showing any other signs that something is wrong, and is eating normally. he has had this without any effects for years, so I was wondering if there really is anything wrong with him. When the crusts fall off, the hair falls off as well and a bald patch is left by the eyes.

Thanks for using PetCoach. There are several possibilities for Pietje's crusty eyes. The first is to make sure that he has adequate Vitamin C supplement. This needs to be in the form of fresh fruits and veggies as well as fresh food, and Vit C supplement (not in the water). A bit more on feeding https://vcahospitals.com/know-your-pet/guinea-pigs-feeding The other differentials include mites or ringworm. A vet visit can help diagnose either of these conditions. The vet may recommend a fungal culture or skin scraping to make a diagnosis. https://vcahospitals.com/know-your-pet/guinea-pigs-problems I hope this helps.
