Between 8 and 12 weeks of age, when retinal development is normally completed in dogs,
signs of vision problems are noticeable.
Looking at people from these same ethnic groups who had moved to places like Australia or the US showed that the increased
risk of vision problems did not occur in other countries.
Countries like Japan, Singapore, and China have high
rates of vision problems in children, and they also have a more intensive education system that focus on reading small words at an early age.
Researchers hypothesized that factors like earlier reading of small print, less exposure to natural light and more use of artificial light, and intense pressure to succeed all contributed to the higher rates
of vision problems in these countries, especially in children.
Get checked The American Academy of Ophthalmology recommends a baseline eye - disease screening at age 40 to detect early signs
of vision problems like cataracts, which block light from reaching the retina; age - related macular degeneration (AMD), a disease that causes deterioration of the retina; and glaucoma, optic - nerve damage caused by increased pressure in the eye.
Depending on the severity of the cataract, affected dogs will display a
range of vision problems from mild to complete blindness.
They found that people who ate a diet high in carotenoids (a class of antioxidants found in brightly colored vegetables) had a 43 % lower
risk of vision problems.
These
types of vision problems could range from color vision deficiency to a lazy eye (amblyopia) but would also include children with vision impairment.
Patients would still get appropriate treatment because ophthalmologists can determine the
cause of vision problems and assess what interventions might be needed.
I've also seen speculation that countries that prioritize stretching and relaxation in elementary schools have lower
rates of vision problems.
From my research, I believe that OGTT blood sugar levels above 140 mg / dL, especially regularly, can increase risk
of vision problems, cancer, stroke and cardiovascular disease, even without an official diabetes diagnosis.
If your dog's eyes look cloudy, fuzzy, white, blue, or even teary, it may be a sign
of vision problems or eye disorders.
