Eye removal

Hi my 11 year old shiz tzu Egan who is blind had to have his last eye removed on Tuesday at our vets on his 2 day post vist on Thursday his eye was very swollen and he aas refusing to eat my vet told me this was normal and to remove the cone so he could hopefully eat and drink they prescribed me oral pain killing tablets to give him when i removed the cone he had a large golf ball pocket under his chin of fluid I took him to an out of hours vet who teated the liquid in the pocket and advised I gave him calpol infant she was shocked at the state of the eye area. Friday morning his eye had double with swelling, weeping and was turning black in areas I again visited my vet Egan was given IV antibiotic’s and a pain killer as his temp had risen to 40.8 and i was asked to take him back yesterday (saturday) the eye continued to swell and weep. Saturday’s visit to the vets involved another round of IV treatment and the vet informing me he was concerned about the black areas as he suspected necrotic tissue and may need anither operation on Monday to deal with this tissue, his eye has continuned to weep over night and Egan is still not eating I have managed with the help of my friend to get the liquid antibiotic and tablet antibiotic into this morning but he is terrified of anything near his mouth. My question is what could cause necrotic tissue and why has he bruised so badly when he had his other eye out he never bruised at all. I’ll attach photos to show the difference in my poor boys eye.

That does look swollen.  Dramatic swelling is common after an enucleation - its an area that bruises easily - but necrosis would not have been desired or intentional.  Necrosis is a rather macabre Greek word - meaning 'death' - and necrotic tissue is simply dead cells, which go black.   Necrosed skin can happen when the blood supply is compromised for some reason, or when there has been high pressure.  I have seen it with infection, cancer, disruption to the blood supply, including post-surgery, or with swelling tight enough to interfere with the blood supply and even with burns, although the latter seems unlikely in this case.  Your vet will hopefully be able to work out what caused it and how things are looking in a few days.

It can sometimes happen following excessive bleeding and excessive bleeding can be associated with clotting problems or open vessels.

Wishing Egan all the best
