What is lenticular sclerosis? – Lenticular sclerosis or nuclear sclerosis is the medical term for a bluish transparent haze that develops in the lens of the eye in middle-aged to senior dogs.

- Vision does not appear to be significantly affected in dogs diagnosed with lenticular sclerosis.” Vision does not appear to be significantly affected in dogs diagnosed with lenticular sclerosis.
- This condition is not the same as cataracts.
- Cataracts are white and opaque and represent a change in the ability of light to penetrate to the retina.
Cataracts cause diminished vision. Cataracts and lenticular sclerosis are two of the most common eye problems seen in dogs over the age of nine. Some estimates show the prevalence of lenticular sclerosis or cataracts at 50% in dogs over nine years of age and 100% in dogs over the age of thirteen.
- Lenticular sclerosis appears as an evenly gray, rounded opacity (cloudiness) in the center of the lens, and is most easily observed when the pupil is dilated.” Lenticular sclerosis typically occurs bilaterally (in both eyes) and symmetrically in dogs.
- Lenticular sclerosis appears as an evenly gray, rounded opacity (cloudiness) in the center of the lens, and is most easily observed when the pupil is dilated.

What does it mean when a dog’s eyes turn GREY?
Arthritis In Dogs & Cats Master Guide Why do an old dog’s eyes go grey? Posted by Media Rocket, 09 Sep 2020 Why do an old dog’s eyes go grey? Have you noticed that your older dog’s eyes become hazy? This is particularly noticeable at night time. There are two common reasons why this happens.
The first condition is age-related. As pets age the fibres in the lens naturally get more dense and compact, creating a greyish blue haze to the centre of the eye. This condition is called “lenticular sclerosis” or “nuclear sclerosis” and does not typically compromise vision. It also leads to night blindness and a loss of depth perception.
Lenticular sclerosis appears as an evenly grey, rounded opacity (cloudiness) in the centre of the lens, and is most easily observed when the pupil is dilated – like during a vet visit or at night time. There is no specific treatment for lenticular sclerosis, nor is treatment necessary.
We would still like to monitor your pet’s eyes regularly to make sure that cataracts are not developing in the eyes. The second reason can be because of cataracts. Cataracts are white and opaque and block light from reaching the retina. This will lead to blindness. Mature cataracts cause the lens to go hard and shrivel up (like a grape becoming a raisin) The loss of water and protein from the lens causes it to shrivel up and form a Mercedes Benz like symbol in the lens.
There are several causes of cataracts, including diabetes, infection, nutritional, and age-related degeneration. Treatment usually is unrewarding in terms of reversing the cataract, and surgery is the only option for a cure. Cataracts and lenticular sclerosis are two of the most common eye problems seen in dogs over the age of nine.
Some estimates show the prevalence of one of the above conditions at 50% in dogs over nine years of age and 100% in dogs over the age of thirteen. There are also other reasons for the eyes of dogs to go cloudy. Sometimes the cornea becomes waterlogged. In these cases, the whole surface of the eye becomes opaque and not just the lens.
This can be a sign that some of the corneal cells are dying (age-related) and the cornea struggles to regulate the amount of water in the cells. The right type of eye drops can help with this. It can also be a sign of severe systemic diseases If you are suspicious of a cataract or a subtle decline in vision, please make an appointment with your family vet straight away.
