Hi, Welcome to Just Answer. I'm Chris, a small animal Vet based in the UK. I am reviewing your question and will get back to you as soon as possible
Sorry to hear of this problem with your Guinea Pig. Thanks for the photos - it looks like she may have a corneal ulcer (damage to the surface of the eye) with bacterial infection as well. This could have been caused by trauma such as bedding getting in her eye. She needs to be seen by your vet as soon as possible, the eye needs to be checked for an ulcer using a special stain and also we need to checked that there is no foreign material (such as hay) under the eyelids. She will need a antibiotic eye drop and most likely some pain relief as well. Hopefully with prompt treatment the eye will make a full recovery.
I hope that answers your question? Please let me know if you need any further help or advice. Thank you for using Just Answer. Best wishes.
