Sheltie Mix Anterior Lens Luxation

January 11, 2010

A ten-year-old Sheltie mix names Trixie blindly sniffed in my direction. She appeared perfectly normal until you focussed on her eyes. Bilateral cataracts had taken Trixie’s sight years before. Today, I saw a new problem.

The lens in her left eye had slipped from behind the brown iris to the front (anterior) aqueous chamber of her eye. The lens looked like a white slippery bouncy ball, jiggling every time Trixie tilted her head. Normally, the torn cilia muscles that hold the lens would send out incredible pain signals causing blinking, squinting, and tearing of the eye.

Trixie didn’t care. Her right eye sported a blood spatter on the backside of the tippy-top of the clear cornea window which makes up the front of the eye. No doubt, the right lens stretched and wrenched at its anchors attempting to join its left compatriot in lens limbo in the forbidden anterior chamber.

Usually, emergency eye surgery to remove the useless, painfully positioned lenses commences urgently. Sometimes a doctor must adjust her beliefs about what may be best for the patient. In Trixie’s case, she experienced no pain. Therefore, no surgery!

In the pictures, her left eye, on your right, contains the anterior lens luxation. Rarely can this lens be seen in a picture because the cornea becomes so irritated by the lens behind it that it turns a blue-white color from fluid build-up within the cell layers (corneal edema).

Trixie’s right eye (on your left) holds a cataract. The cataract also appears white, but it is peeking through the pupil in the lens, not an oval form in front of it compared to the left eye.

    Is it common for sheltie mixs to have eye problems? My sheltie/cocker mix has an eye problem and has to be on drops now 😦

      It is super common for Cockers to have eye problems. Shelties not so much.

    Does that also happens with human lens? My grandfather has a cataract (since 2007) on his left eye and he was never treated by any doctor. Is there a possibility that cataracts won’t get worst until blindness? Are there exercises to prevent from this?

      Are you kidding? Did you just ask me questions about humans? Do I have to get glasses? Or did you just ask a veterinarian about human stuff?!? Ask a “human” doctor! (I’m just an animal, aren’t I? 😉 )

      Plus, I think you’re randomly spamming me and will never read this….I hope somebody is amused!
