My dog has glaucoma. Should I choose eye injection or removal?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 60 lbs

My dog has primary glaucoma & is permanently blind in one eye & I'm down to 2 options: Standard removal or an injection to the eye with an apparent 90%~ success rate that basically prevents the pressure building fluid from producing. What should I expect if I chose the injection? How does the eye change? What are the risks? Is it safer? What are you experiences with this option? Do many end up still getting the eye removed AFTER the injection? Ultimately what is your personal opinion?

Hello. The procedure involves injecting gentamicin into the eye. The procedure is safe, relatively quick & generally done under sedation. The procedure does not always work, some dogs will relapse in 3-6 months, but the injection can be repeated at this time. In some cases, the eye will shrink, what we call end stage, but not always. This is a good option if you are not ready to consider enucleation. If successful, the injection protocol can result in a non-painful & quiet eye. No one can predict final outcome, but this is a nice way to preserve the eye & keep Izzy comfortable. Thanks for using Petco Pet Education Center, formerly Petcoach.
