Cataract(HC)
Also known as: Grauer Star · Hereditary Cataract · Linsentrübung · Juvenile Katarakt · Cataracta · …
Overview
What it is
A cataract is a progressive clouding of the lens inside the dog's eye, which is the clear structure that focuses light onto the retina at the back of the eye. When the lens becomes cloudy or opaque, it blocks light from entering, gradually impairing the dog's vision. If left untreated, this condition can eventually lead to complete blindness in the affected eye.
How it presents
Owners may notice a cloudy, bluish-grey, or white discoloration inside the dog's pupil, along with signs of vision loss like bumping into objects. Depending on the genetic cause, these symptoms can appear as early as puppyhood or develop later in adult dogs.
Treatment
While cataracts cannot be cured with medication, they can be treated successfully with a one-time surgical procedure to remove the cloudy lens. This specialized surgery typically costs between 2,000 and 5,000 EUR.
