Have you ever found yourself getting really sleepy and start
rubbing your eyes? After rubbing your eyes do you sometimes see stars? Well, if
so then you have just given yourself a small dose of ocular compression. Ocular
compression is one of many techniques used to shorten, lessen the severity of,
or stop canine seizures. Before I go any
further let me say this: I do not know if this works the same for human seizures.
I have tried looking it up and haven’t been able to find much in the way of
results for people.
Ocular compression is performed as soon as your dog starts
to show sign that they are going to have a seizure. It is performed throughput
the seizure as well as into the post-ictal phase. I’m sure you are asking
yourself what in the world is Ocular compression? Well, I will give you the
best explanation I can.
With your dog’s head balanced between both hands, use your
thumbs to hold the eye lids closed and press steady gentle pressure to both
eyes. (The amount of pressure will be
about as much pressure as you would put to your wrist when looking for a
pulse.) Hold this pressure for a count of 10-15 then release for a count of 10.
This process can be repeated until signs of the seizure have stopped.
During a seizure there are violent neural discharges of
electrical activity in the brain. These discharges bounce from one hemisphere
to the other which cause the violent spastic movements often associated with a
seizure. When ocular compression is
applied there is pressure applied to the vagus nerve. The vagus nerve releases
the neurotransmitter GABA (gamma-amniobutyric acid). GABA acts as a natural
inhibitory neurotransmitter in the brain that interrupts the flow of nerve
impulses.
All of that sounds really fancy but, it probably doesn’t
give you any information at all. Basically, what it means is that when pressure
is applied to the vagus nerve it briefly shuts off the electricity in the
brain. Once the pressure is released the electricity starts flowing again and
it follows the currents that it is supposed to follow.
By stopping and restarting the electrical flow in the brain
it decreases the heart rate, forces the bodies muscle groups to relax, and
gives the brain a chance to regain control and stop the seizure.
Through all of the studies that have been done on this
procedure doctors have been unable to determine the full extent of how much
ocular compression helps dogs during seizures. Although they all agree that
length and severity of seizures is greatly reduced with the application of OC.
From my personal experience with Baron his seizures usually
lasted between 2 to 3 minutes before using OC. Now, the lengths of his seizures
have reduced to on average 1-1 ½ minutes and they aren’t as violent. It has definitely
become a valuable tool in the battle against epilepsy.
