Hyperglycemia, or high blood sugar, is a condition where the blood contains an excessively high amount of glucose, at a level of 10+ mmol/L (180 mg/dl). Chronic high sugar levels exceeding 125 mg/dl can lead to permanent organ damage. |
Hyperglycemia can occur in diabetics and non-diabetics. Obesity is the most common cause of non-diabetic hyperglycemia. The accepted cure is to reduce the body’s excess white fat reserves.
One of the possible problems associated with high blood sugar is blurred vision which develops rapidly with the onset of the disease. This is caused because the high blood sugar causes the lenses of the eyes to swell which alters the ability to see. Blurred vision can also be symptomatic of other eye conditions associated with diabetes.
Cataracts or clouding of the normally clear lens of the eye. While anyone can suffer from cataract, it is more likely with someone affected by diabetes. Focusing of light is affected with a cataract and diabetes resulting in impaired vision. The normal treatment is surgery followed with spectacles to further correct vision.
Glaucoma. This is a condition when the fluid builds up pressure inside the eye and fails to drain properly. The sustained pressure results in damage to the nerves and vessels in the eye causing significant loss of vision.
Diabetic retinopathy is one of the vascular problems associated with diabetes. This complication is caused by damage to small vessels within the eye. It is the leading cause of irreversible blindness. The longer one has diabetes, the greater the risk of contracting this serious eye disease.
