Have you heard about tear stains in dogs? Tear stains, sometimes called eye stains or tear marks, are commonly caused by molecules that contain iron called porphyrins that sit on the hair coat for a long time. In other cases, tear staining is brought about by an anatomical abnormality in the eye or eyes, but in other cases, it could be a sign of a far worse health issue. Tear staining can be caused by the presence of an irritant in the eye. An inverted eyelid, ingrown eyelash, or hair that is growing so close to an eye, among others can bring about irritation. Tear staining can also be caused by an eye infection, glaucoma, as well as a tear duct that does not drain properly. Entropion (eyelids turned inward), shallow eye sockets, as well as the blockage of puncta (drainage holes of the eyes) are also linked to tear duct drainage issues.
Considering that tear staining can also be caused by a variety of underlying health issues, a visit to your veterinarians San Diego CA should be made sooner rather than later.
