There are many myths surrounding diabetes, and it can be hard to determine what is true and what is not. Many patients want to know if diabetes will really make them go blind. The fact is that the disease can certainly cause blindness, and is one of the top causes of blindness among adults. Equally important, however, is the realization that proper testing and eye care can often prevent the condition from occurring.



The vision problem that causes blindness in diabetics is also known as retinopathy. Retinopathy is damage to the eye due to blood flow problems. It causes decreased vision and when left untreated leads to blindness.



When your blood sugar is not well controlled, the blood vessels in the eye become weak. This leaks fluid into the part of the eye responsible for vision. Eventually the blood vessels close off, stopping blood flow to the retina. As the disease progresses, new blood vessels form. These vessels are quite fragile and bleed into the eyes causing severe vision problems and blindness.



Retinopathy occurs in approximately eight percent of patients in the first three years, with statistics rising to one quarter after five years and jumping to eighty percent after approximately fifteen years of being diagnosed with diabetes of any form. These percentages are quite large, but they do not mean that the same percentage of patients will go blind. They point instead to the reasons you should be tested annually for the problem.



When you have your vision checked annually, your eye doctor will be able to catch retinopathy in the early stages. In this stage, the condition is easily treatable. Controlling your blood sugar can also prevent the condition or help delay the onset and progression. It is very important to contact your eye doctor if you experience any vision changes including blurriness or trouble seeing clearly.



Blindness is still considered a side effect of diabetes even though it is preventable. Many patients do not have their vision tested often enough or fail to report symptoms. When you are diagnosed with diabetes, it becomes imperative that you have annual vision tests. When retinopathy is diagnosed early, it can be treated before symptoms become permanent and severe. Your vision is very important to your quality of life. If you are experiencing blurred vision or have not recently had your vision tested, seeking an eye exam is one of the best things you can do for yourself.

Cats naturally have superior vision. However, there are various conditions that can cause blindness in cats. Some of these conditions include hypertension, glaucoma, and cancer. Let's take a look at some of these causes of feline blindness.



Hypertension



Hypertension, or high blood pressure, is one of the leading causes of blindness in cats. If left untreated, the pressure can cause the retina to rupture. This can occur in just a matter of days. Cats that have kidney disease, diabetes, or hyperthyroidism have the highest risk of developing hypertension.



An early sign that your cat is suffering from high blood pressure is the presence of dilated pupils. The pupils won't respond to a change in light, and there also may be blood in your cat's eye. Hypertension is dealt with by treating the underlying cause. Your cat may also need to start eating foods low in sodium.



Glaucoma



One of the next common causes of feline blindness is glaucoma. Glaucoma is a condition in which there is too much pressure within the eye. It is also a common problem for humans. If your cat is diagnosed in the early stages, the pressure may be reduced via medications. If it has already progressed, your cat may need surgery to correct the problem.



Cancer



Another cause of blindness in cats is cancer. Tumors can grow in or around the eye. In most cases, the eye will need to be surgically removed. However, it is usually replaced with a prosthetic eye to give a more natural look.



Atrophy



Progressive retinal atrophy is an untreatable condition that leads to feline blindness. Most cats suffer from this condition because they inherited it. The disease progresses slowly over time, but will lead to total blindness.



Kidney Disease



One of the final common causes is kidney disease. It is common for older cats to suffer problems like chronic renal failure as they age. Unfortunately, chronic renal failure leads to hypertension. As stated earlier, hypertension can easily cause sudden blindness in cats if the retina ruptures.
