You have noticed that your four-legged friends’ eyes appear bluish-grey or hazy and you didn’t notice it before. What are the causes, and should you be worried?Cloudy eyes are a symptom of a variety of eye conditions. Knowing the difference between these will alleviate your concerns, and help you decide whether to seek veterinary advice.
Nuclear sclerosis (Lenticular sclerosis) is when the lens nucleus becomes denser and harder and will be visible as a greyish blue haze. It rarely causes vision impairment but focusing ability may be affected. This condition is usually gradual, and age related from 6 years. Advanced nuclear sclerosis may appear like a cataract and is frequently confused by owners.
Cataracts is the loss of transparency of the lens nucleus as a result of abnormal lens metabolism and will appear white or opaque. Cataracts usually come on suddenly, but it can be an inherited trait and will then develop gradually, so don’t assume slow change equals sclerosis. Cataracts can cause vision impairment, glaucoma, pain and blindness if not treated. Common causes for cataracts include: Inherited conditions, Diabetes, Ocular disease, Physical trauma, Nutritional deficiency, Aging (over 8 years).
Less common causes of cloudy eyes, but of greater concern are glaucoma, nuclear dystrophy, pannus, corneal ulcers, dry eye and anterior uveitis.
