Claire, Bon Bon is just 5 years old and the operation went extremely well, her eye was a mess (cloudy, weeping and what looked like sank in the middle of it, but was bulging out as well - if that makes any sense. I found that the eye drops sometimes made me think it was weeping, but this was not always the case.) her eye also looked so painful. Bon Bon was born blind in her other eye so they thought it a huge risk but she has adjusted really well to being blind and they have made a smashing job of her stitches. I would put a picture up but I am not sure how to do it.
Biscuit (Bon Bon's sister) has her eye removed in January of this year due to an abscess behind her eye, hers was much much worse than Bon Bon's and she made a full recovery and is back to her normal self and gets on very well in life.
It is such a hard decision to make but both my girls have adjusted well and despite the operation forgave me extremely quickly :-)
It is great news that Eliza is eating and drinking because Bon Bon stopped and was hard work when the syringe feeding came, we had tears and tantrums (I say we, in fact only me).
When Biscuits eye was crusting and weeping I would wipe around it for her. I think that the drops often caused it to go dry and crusty.
I hope that this has been of some help to you, I have been through it twice (although with different guinea pigs and different eye issues and both times it made me worried sick and just unable to function.)
I am sure Eliza is stronger then we think, my little ladies were both rescue guineas (along with their sister Marshmellow RIP) and were terribly weak when I got them all those years ago and that made me wonder if they'd be strong enough, but my oh my, they surprise you.
Please contact me if I can help/support in any way then I'll be glad to do so.
