Can you use a ophthalmoscope to see if there's scratches on the front surface of a guinea pig eyes or if there is hay behind the eye? Could you tell me what they are used for and how they work and what you can see with them?

Usually the scratch can be seen without magnification lens and yes the ophthalmoscope is needed to look inside the anterior chamber. Fluorescein stain is used by vets to see and diagnose corneal scratches /ulcerations. It is a stain which can remain on the cornea if damaged. A check up would be ideal in her case.
