Juvenile Cataracts
Hereditary cataracts cause lens opacity in dogs, often leading to vision impairment or blindness, and can develop at a young age.
Detailed Description
Cataracts are characterized by the clouding of the lens, which impairs vision. In hereditary forms, such as those seen in some breeds, the condition is caused by abnormal lens protein metabolism and can progress rapidly, potentially resulting in blindness if untreated.
Common Symptoms
- Cloudy or bluish appearance to the eye
- Vision impairment
- Bumping into objects
- Reluctance to move in unfamiliar areas
Management Options
- Surgical removal of the lens (phacoemulsification)
- No effective medical therapy
