What is croup? Croup is a fairly common respiratory condition in children usually caused by a viral infection or allergic reaction. Croup affects the windpipe (trachea), the bronchi (airways to the lungs), and the larynx (voice box).
However, as the cataract continues to become denser, vision also becomes more cloudy, and stronger glasses or contact lenses will no longer improve sight. Cataracts typically develop gradually and are usually not painful or associated with any eye redness or other symptoms unless they become extremely advanced.
The complications from cataracts themselves are fairly basic. The most common effects are vision loss, which can sometimes be so severe as to result in total blindness. Dogs with vision loss are more susceptible to a variety of accidental injury as a result of not being able to see properly.
