How does cataracts begin in dogs? - briefly

Cataracts in dogs typically begin with a gradual clouding of the lens in their eyes, usually due to aging or genetics. This process can progress slowly over time, leading to reduced vision and eventual blindness if left untreated.

How does cataracts begin in dogs? - in detail

Cataracts in dogs typically begin with changes in the proteins and fibers that make up the lens of the eye. The lens is normally clear, allowing light to pass through and focus on the retina at the back of the eye. However, as dogs age or due to certain genetic predispositions, these proteins can start to clump together, forming small opacities within the lens. These opacities initially may not affect vision significantly, but they can gradually grow and spread, eventually leading to a cloudy or milky appearance of the lens. This cloudiness interferes with light transmission, resulting in decreased visual clarity and acuity. In some cases, cataracts can progress rapidly, while in others, they may develop slowly over time. Factors such as breed, age, and underlying health conditions can influence the onset and progression of cataracts in dogs. Regular veterinary check-ups are essential for early detection and monitoring of this common eye condition.
