Ciliary Body Ablation for Glaucoma vs Enucleation

Hi there. My dog has glaucoma (diagnosed in 2020) and has had one enucleation of his right eye two years ago. His left eye is now showing high pressure (60) even on drops. He had a horrible time with the recovery from the first enucleation, and I am trying to find other options for him. I was told today that my dog isn't a candidate for Ciliary Body Ablation. My vet said it was due to his cataract on the eye. I am trying to find information on what disqualifies a dog from this injection, but so far everything I am finding says that the injection is usually used on geriatric dogs. Geriatric dogs are most likely to have cataracts, so I am wondering if she is mistaken... She did tell me she has never done the injection before. My dog is 13 this year. Any info is appreciated. Thanks!

I thought I might add for clarity that I am just looking for information about what would disqualify a dog from CBA. My vet didn't elaborate on the "why" other than to say "His cataract makes him ineligible".

Hello!  This is quite specialist stuff - I haven't met a canine patient that has had it done.  I can see why it is important to find out and would fully reccomend pinning your vet down on the subject or asking them to pin down the specialist - I was unable to find a definitive answer.  The human articles I found on the subject all assumed glaucoma surgery at the same time.  I do have two hypotheses, but your vet would have to supply their reason in your dogs' particular case......   1) Glaucoma, as you'll know, is thickening of the lens and I wonder if this might prevent the physical act of Ciliary Body Ablation ie get in the way of the laser, for example.   Furthermore, if glaucoma is already causing blindness, then where the goal is to retain existing sight, glaucoma may prevent this.   2)  It may simply be that from a welfare point of view, if little difference will be made to the vision, it is thought to be kinder and more simple to use the established option to treat the problem.  The complications experienced previously were unfortunate but might not happen another time.  Obviously nobody can guarentee this, but I wonder whether a specialist conducting the procedure would help to improve outcomes? Thank you for sharing this fascinating case and we would be interested to hear what you find out and how the case is resolved.

Apologies:  typo.  Please read as.... 'Cataract, as you know, is a thickening of the lens.'  This way it makes better sense.
