This month we continue our exploration of Nature’s great wonder, the eye. As we move past the anterior chamber and beyond the deep surface of the lens, we leave all familiar structures behind. Welcome to the Posterior Chamber!
This is a strange and dark place. Gone is the sparkling clear aqueous humor that inflates and nourishes the front of the eye. Instead, the posterior chamber is filled with a gelatinous tissue, the vitreous humor, which fills the space behind the lens and in front of the retina. This material not only helps to maintain the spherical shape of the eye, but also serves to maintain the location and flatness of the retina by gently compressing the retina against the fibrous globe. The posterior chamber is dark - exactly like the back of a camera.

In 2018, Californians overwhelmingly voted, for the second time, to protect farm animals from cruel and inhumane conditions. Numerous pieces of legislation have been passed at both the state and local level to protect companion animals from mistreatment and discrimination. Now, a proposal to ban the sale and production of fur in the state is working its way through the legislative process.

Welcome back to our exploration the eye. We have now reached the deepest limits of the anterior chamber, the forward-most space of the eye. When we move into the eye's deeper spaces, the clear liquid of the anterior chamber is replaced with gel and all of the moving, focusing, familiar parts of the eye give way to the amazingly complex neural networks where the actual work of vision takes place. The anterior chamber is functionally the "cam-era" portion of the eye, while the "film" is further back. We’ll get there.

Conservation biologists from Audubon Canyon Ranch (ACR) shared the exciting news that two mountain lion kittens were born at Trione-Annadel State Park in early February to a female mountain lion being tracked by ACR’s Living with Lions research study.

Every student of anatomy has heard it a thousand times: "Structure Follows Function." We need only to study the structure of a particular organ to glean precious insight into its func-tion. When looked at closely, the structure of the eye is nothing less than astounding. Be-fore we can discuss the health or disease of the eye, we must consider its structure.Every student of anatomy has heard it a thousand times: "Structure Follows Function."

Be-fore we can discuss the health or disease of the eye, we must consider its structure. Diseases of the lens are many and common. Age itself leads to drying of the lens tissue, which decreases lens flexibility and leads to far-sightedness. When the drying process is more severe it creates the noticeable fogging of the lens (nucle-ar sclerosis) seen in many of our senior dogs.

The tapetum lucidum is typically much more developed in animals and is often very brightly colored when compared to that of humans. It is particularly amazing that light sig-nals are perceived when they pass through the retina, and then again when they reflect back off the tapetum! This visual signal amplification helps improve night vision. Development of the tapetum is related to the particular species’ benefit from vision under low-light conditions. Dogs and cats have a well-developed tapetum lucidum, while in hu-mans, the tapetum is developed enough to ruin flash photographs but not nearly well enough for us to stroll at night without a flashlight.

I thought our property was free from mountain lions. But, after mysteriously losing four goats within a few months, I learned more about mountain lions than I ever wanted to know.

A veterinary practice is a doctor’s office, sure, but it’s also a hospital, a surgical center, a pharmacy, and an emergency care center. It’s an employer and community resource and wildlife rescue gateway. It’s part of the community; more than just a busi-ness, it’s an institution. People depend on it for help.And so, I find myself contemplating the future of Bodega Bay Veterinary Hospital.
