I took Beni to Cornell yesterday for his regular visit. Beni has been having some issues with his vision since mid-July. I took him there last month as a semi-emergency two weeks before his scheduled visit on July 30th because of some different behavior I had been seeing. The villian in all of this is not related to the glaucoma but is now being caused by that cataract deep inside his eye... it's getting worse. Because of the glaucoma issue Beni is not a good candidate for cataract surgery.
Anyway back in July when Beni was examined... Dr Kern told me that the eye itself was substantially clear. Clear enough to where he got a good look at the cataract which he said then appeared to be getting worse. His pressure on that day was 7 which was excellent.
Over the last 6 weeks Beni has been much of the same. He isn't in any discomfort as the glaucoma is being controlled but at times... especially after being given his meds he has struggled at times with his vision. The problem is this... the Xalatan works to reduce the pressure in the eye along with the Cosopt. As a result Beni's pupil also shrinks to almost a pinpoint. As bad luck would have it... this cataract is situated right in front of the pupil which means Beni has to try and look "around" this obstruction.
Yesterday during his examination Dr Ledbetter made the same observation about the cataract. We talked at great length about the glaucoma being under control and Beni's eye pressure continually reading in the single digits. Yesterday the reading was 6. What we talked about was changing the Xalatan from twice a day to once a day at night. The thought was that this would expand Beni's pupil during the day to make it easier for him to see around the cataract. By giving the Xalatan at night would mean that Beni is sleeping through most of it's effect on the pupil. This is a HUGE risk. The doctors have always talked about not wanting to change any of the meds while they have been working so well at keeping the glaucoma under control.
Again we talked about the risk being huge but the eye has been doing well for quite some time. Even a slight rise in pressure would not be detrimental to his sight as long as it stays below 25. The eventual outcome no matter what will still be the same. At some point in time Beni will be blind... but it seems the cataract will be the cause before the glaucoma is.
So today was the first day on the new schedule and it went reasonably well. I could see where Beni had a much better time in getting around and even seemed more alert and active. Of course the pressure is really on me to monitor the eye even more closely than I already am for any changes. At the first sign of any change I am to call them immediately. The good thing is I am on vacation through next week so I can keep close tabs on him.
It was three years ago this past Tuesday that Beni was first diagnosed with glaucoma. We've been through a lot the two of us over this time but he is afterall my velcro dog.
