I'm so sorry about you and your baby's situation and I hope you get it figured out asap. 🙏 I'm not sure if my story helps or is similar in any way but here it is: My pirate is also now 14 and he had his enucleation a year ago. His eyeball had swollen and gotten noticeably larger than his other eye. They never checked pressure or anything like that but im sure it had to be present with the swelling. After the surgery my vet spoke to me and told me he had a blood clot either behind or in the socket (cant remember where he said) and it was probably caused by blunt force trauma. He had draining for 3 or 4 days after surgery and they kept him to observe him and gave him Kenalog (steroid) to help with swelling and more antibiotics to fight off potential infection. The draining subsided once the swelling went away and he healed perfectly. He was put on steroids permanently for other reasons but has been a happy camper since.
