What is lenticular sclerosis?

It’s a term for the bluish transparent haze that develops in the eye lens due to aging ( from middle-aged to senior dogs), you can see it as bluish discoloration or cloudiness that appears on the pupil and it makes it less clear.

They can still see but their vision will be more blurry, it’s kinda like if they were wearing dirty glasses, however, it’s not something to worry about as it’s a normal age-related process.

Symptoms

  • Evenly gray (kinda bluish) pupil 
  • When the pupil dilates, it is easily noticed
  • If you looked at it from the side the opacity will be more obvious than from the front.

What are cataracts?

It’s also cloudiness that makes the eyes look a little bluish, it develops a crystalline lens which looks a little blue in the light.

It changes from a small dot to the whole lens, it will cause them a problem in their sight because it doesn’t permit the image to form on the retina, in conclusion, they will lose their vision.

Symptoms 

  • Watery eyes
  • Squinting
  • Signs of vision loss (can’t see their food, bumping into walls, or can’t recognize familiar faces)
  • Unwilling to jump or climb
  • Scratching or rubbing their eyes
  • Difficulty seeing in the morning or in a dimly lit place
  • The pupil size will change
  • Change in the eye color
  • Cloudy eyes

What is glaucoma? 

Glaucoma is a much bigger problem, it’s really painful for them and they will end up losing their eyesight.

It builds up fluid in the eye and this fluid will put pressure on the eye, and the more the fluid builds upon the eye the more the pressure increases.

It affects one eye at a time, the white part will turn red and will be a little swollen and they will look like they are popping up from their head.

Symptoms 

  • Signs of pain
  • Sleeping more than usual
  • Watery eyes
  • Tilting their head a lot or being head shy
  • Dilated pupils
  • Cloudy eyes
  • Blue appearance in the eye (it could also appear as hazy in some dogs)
  • The white part of the eye turns red

Glaucoma can not be cured but, fortunately, it can be controlled by laser, eye drops, surgical operations, or pills. To prevent vision loss, as soon as the symptoms appear take them to the vet.

The good news is cataracts can be cured by surgery and they can restore their vision again, their vet will discuss the surgical options with you and will recommend what’s best for your dog’s vision. The surgery will be similar to human surgery.

Whether it’s lenticular sclerosis, cataracts, or glaucoma, you should take them to the vet if their eyes turned blue for an accurate diagnosis. Only the vet will tell what’s better for them.

They could just give them eye drops, pills, or something more serious such as laser or surgical operations.

The sooner you take them to the vet the better chances they will have to prevent any loss of sight.
