Your pet’s eye health is important!
Here at VCA Leon Springs, we care about all aspects of your pet’s health – including vision health! Although the eyes are examined during routine wellness exams, sometimes, when problems develop, a more in-depth examination is necessary.
When the doctor needs to perform this more detailed exam, he or she will often use a device called a tonopen. Through a processed called tonometry, the doctor is able to calculate and measure the intraocular pressure of the eye. This measurement is gathered by assessing the fluids within the eye.
The size and shape of the normal eye is maintained by the amount of fluids in the eye, and the pressure created. This pressure is known as the intraocular pressure. The fluids within the eye are continually produced by a structure called the ciliary body. In addition to producing the fluids (which are often called the aqueous humors) the ciliary body contains the suspensory ligaments which hold the eye’s lens in place. Muscles within the ciliary body then pull on these ligaments and control the shape and focusing ability of the lens.
The aqueous humors within the eye contain both nutrients and the oxygen used by the different structures within the eye. When there is an excess of this fluid it is drained from a part of the eye located between the cornea and the iris called the iridocorneal angle. So long as the production and drainage of this fluid is maintained, the intraocular pressure remains balanced.
An imbalance in the production and drainage of the fluids however, can lead to ocular problems. Signs your pet may need to have their eyes examined can include:
- Red or Irritated looking Eyes
- When a pet has suffered head or orbital trauma
- When monitoring drug therapy for glaucoma
If you have any concerns about your pet’s vision or ocular health, contact us today and set up an appointment with your veterinarian.
