| Secondary Glaucoma due to Lens Luxation in a Dog Posted: 11 Nov 2009 04:52 AM PST
There are two broad classifications with glaucoma. Primary glaucoma is due to a defect in the eye's drainage system and tends to be inherited. Secondary glaucoma is also the result of poor fluid drainage from the eye but the defect is due to some other issue. For instance, a tumor may be present that disrupts the outflow of aqueous humor and the resulting increase in intra ocular pressure is secondary to the presence of the tumor. Another form of secondary glaucoma is due to something called lens luxation. The lens is the structure in the eye that helps us focus. Cataracts form in the lens resulting in clouding and loss of sight. The lens is held in place by fibers that attach to the inside of the eye. In certain breeds these fibers break down Lens luxation can be the result of trauma but more commonly, it, too, is an inherited defect. Lens luxation is more common in Border Collies, Brittany Spaniels, and many terrier breeds. In fact, our reader has a Wheaten Terrier that has glaucoma secondary to lens luxation. She had been to see a veterinary ophthalmologist and he had recommended surgery to remove the lens to correct the glaucoma. Her dog was receiving medical treatment for the pressure build up and she wanted to know my opinion on the surgery. It's really a matter of timing and the potential for preserving some sight in the My assumption, in this case, is that the ophthalmologist assumed there had not been irreversible damage due to the glaucoma. In that case the surgery is really the only hope. If you don't remove the cause of the outflow problem you don't have a real chance of preserving the eye and some vision. It doesn't make much sense to treat a problem medically when the cause is a physical blockage that could be removed surgically. There are no guarantees. though. All surgery involves risk and the outcome is not guaranteed. In this case it seems that the risk of surgery is justified. |
| Dogs better than cats? I don't think so! (a word from the Wabby) Posted: 10 Nov 2009 05:27 AM PST
Seriously, hasn't this person (unless it's a dog...yeah, maybe a dog wrote it!) is clueless, he must not know that "dogs drool, cats rule." Who doesn't know that? Cats are easy to live with, we keep our space clean, we don't cause a lot of trouble, and you don't have to walk us twice a day! Really, dogs do drool - tell me they don't! And, they bark, for gosh sakes, they bark all the time! Our dog didn't bark much, but I knew her when she was just a puppy and I had time to train her properly. Other dogs can't stop barking, if you ask me. And they do horrible things like: jump up on you (with muddy paws - eeewwww!), lick your face (slobber all over you, is a better way to say it), sniff you in places they shouldn't be sniffing, and the worst offense of all...they chase cats! Not to mention, dogs smell...especially on rainy days! Cats are soft and when we purr in your ear, it's soothing. I know this cause my Mom says so. Really now, how can all THAT dog-behavior be better than having a nice, calm, cuddly kitty? Or two? If you have good toys for us, and climbing things, and a soft bed, we're happy. Hey, we don't even eat as much as dogs! I have watched dogs eat! Miss Manners would throw her hands up in horror. Not so with the cats of the world - we're quite particular and do not like to get our food or water all over ourselves. And after we eat, we do clean up properly. I never forget to wash my face. My Mom will prolly write about that book - and I'll be watching. To all my cat friends, after her report, I'll give you mine. No way are dogs better than cats! Ha! |
