Dear Daisy Dog
Jazzy, my 10-year-old toy poodle, squints when she goes out in bright sunlight. Her veterinarian said she has iris atrophy for which there is no treatment.
Can you suggest something for her squinting? I live in Florida, where the sun is very bright.
As we age, most of our muscles lose their tone. The eye’s colored iris, the muscle that encircles the pupil and determines its size, is no exception.
While any dog can develop iris atrophy, it occurs most commonly in older, small-breed dogs. On physical examination, the pupillary opening is larger than usual, its normally smooth border appears ragged, and the iris itself develops lacy holes.
Your veterinarian is correct that no treatment is available. However, if the bright sun bothers Jazzy, you can fit her with a sun visor and doggie sunglasses, such as Doggles. For more information, visit www.doggles.com.
Doggles, with their interchangeable impact-resistant lenses, also protect the eyes from wind, insects and road debris, so they’re ideal for dogs that lean their heads out the window when they ride in the car.
