Cataracts
Info
Cataracts are opacities in the lens of the eye that block light from reaching the retina, causing vision impairment or blindness. They appear as a white, grey, or blue cloudiness within the pupil.
Signs:
- Cloudiness or opacity in the pupil (the black centre of the eye)
- Changes in visual ability (bumping into objects, hesitant on stairs)
- Reluctance to jump or navigate unfamiliar areas
- Clumsiness or misjudging distances
- In some cases, signs of eye inflammation if the cataract is causing secondary problems
Common Causes:
- Age-related: Common in senior pets
- Diabetes mellitus: A leading cause in dogs
- Hereditary/congenital: Present at birth or developing early in life
- Trauma: Eye injuries
- Toxins: Certain medications or poisons
- Nutrition: Deficiencies in puppies
Management:
- Schedule a veterinary appointment for proper diagnosis.
- Monitor for signs of secondary complications (redness, tearing, discomfort).
- Make home adjustments for vision-impaired pets:
- Keep furniture arrangements consistent
- Use baby gates to block stairs
- Avoid startling your pet
- Use scent markers or textured rugs as navigation aids
Important Warning
While cataracts themselves are not an emergency, they can sometimes lead to other problems like lens-induced uveitis (inflammation) or glaucoma. If a pet with known cataracts suddenly shows signs of pain or significant redness, seek veterinary care promptly. Cataract surgery is an option for some pets.
