If your dog is having problems with his vision, retinal detachment
surgery may be something that you want to consider and talk over
with your vet.
What Is Retinal Detachment?
This is a disorder that causes the retina (light-sensitive tissue
located on the back of the eye) to fall away from the tissue supporting
it. This is considered to be a very serious situation, as a lack of
quick action and treatment can lead to the retina detaching itself
entirely. This leads to vision loss and even complete blindness of your
dog.
Causes of Retinal Detachment
There are multiple factors that can lead to this disorder, including
but not limited to:
There are a few things to keep an eye out for when concerned about
retinal detachment.
Eye fluid. Retinal detachment can cause fluid to build up in
the eye, so you may notice that your dog's eyes have begun to leak or
that they appear to have blood in them.
Clumsiness. If your dog isn't able to see as well as usual,
clumsiness is often an easy way to tell. Does your dog head in the wrong
direction often? Does your dog walk into things? Does your dog often
appear lost or confused?
Dilated pupils. This disorder will cause pupils to
become dilated. The dilated pupils will have little to no pupillary
light reflex.
Retinal Detachment Surgery
Surgery is one of the most popular choices when it comes to treating
retinal detachment. It is often very successful in either stopping the
damage from continuing, or reattaching the retina if the disorder is
caught soon enough - especially if the retina is not completely
detached. There are several different kinds of surgeries.
Pneumatic Retinopexy. This is when a gas bubble is injected
into the eye. After this is done, freezing or laser treatments will be
applied to the retinal hole. Moving the dog's head allows for the gas
bubble to lay against the hole. Often, your dog will have to keep his
head in the position for a few days, so that the bubble has time to
attach itself and form properly. This will stop up the hole in the
retina, though the position of the head makes it a poor choice of
surgeries if the retinal problems are in the lower sections of the eye.
In most cases, this surgery will be combined with laser photocoagulation
or cryopexy.
Scleral Buckle Surgery. A simpler surgery, this involves
sewing one or several silicone bands to the outside of your dog's
eyeball. This is so the eye will be pressed back against the hole, where
it will be given a chance to reattach itself. These bands usually won't
need to be removed. The most common problem with this surgery is that
it stands a good chance of leaving your dog more short-sighted.
Vitrectomy. This is one of the more commonly used surgeries
for retinal detachment. It removes the vitreous gel and often makes use
of the same gas bubbles that are used in the pnuematic retinopexy. While
your dog will suffer no short-sighted problems as a result of this
surgery, there are higher risks for cataracts forming in the eye that
required the surgery.
Which surgery is best for your dog depends upon what caused the
disorder and how far it has advanced. Sometimes surgery isn't even
necessary. To decide which course of action is best, you will need to
speak to your veterinarian.
