This morning,
the campers got the chance to experience Equine lab. Equine, is all about
horses, so the morning was full of learning all about these beautiful creatures.
The campers were split into three groups and taken to three different rooms to
observe and participate in an eye exam, an ultrasound and the viewing of Nick’s
(the ‘painted’ horse) anatomy, both skeleton and internal organs.
In exam room
#1 was Dr. Brashier who was giving an eye exam on Tigger. Similar to when a
human gets an eye exam, Dr. Brashier dilated the eyes so as to get a better
view of all of the ocular structures, more importantly the fundus. Unlike a
human though, Tigger had to be lightly sedated in order for a thorough ocular
exam to be performed. If you don’t know, a horse’s head weighs around one
hundred pounds, so the doctor has to be extra careful when treating the
patient. As he got started, Dr. Brashier instructed the kids on basic eye anatomy
and the turned off the lights to get a better view of the pupil. He taught the
campers a little bit about what happens when light touches the eye and what to
expect from it when it did. Before light touches a horses eye it is round, but
once light shines on it, the pupil turns horizontal. Next, the campers learned
about the tapetum, which is a light reflective tissue in the eye. The tapetum
has two basic parts, the upper two-thirds of the eye is a greenish reflective
color and the bottom is one-third blue grey. Dr. Brashier instructed the
campers on how to hold a light probe in order to see the fundus for themselves.
Each camper got to hold the lens up to the horse’s eye, and using a
transluminator, they were able to also see the horse’s optic disc.
In exam room
#2 was Dr. Crabtree and the mare, Blackfoot. Here, the campers were shown,
through ultrasound, Blackfoot’s internal organs. They were able to see the
lungs, kidneys and the spleen to start. Each camper got to grab the probe and
place it just in front of the last rib in order to see both the spleen and left
kidney. Dr. Crabtree says this is what every first year doctor is taught when
getting into the program, so getting this hands on experience and knowledge is
very beneficial to the teens and gives them each a head start in their future
studies. Hopefully if they stay the route, the campers will be ahead of the
game and be able to point out exactly where to place the probe to find each of
these internal organs.
