Apart from letting you know if you have an impaired eyesight, your eyes can say much more about your health. Many people often neglect their eye health by not having regular eye check-ups not realizing how important eye health is. Apart from adding to a good quality of life if your eyes are functioning well, the eyes can help diagnose conditions that you may not know you have.
Some common conditions that can be diagnosed through an eye exam are:
A blurred vision and poor night vision do not only show a problem with your eyes, but it could actually mean you have diabetes. Often when the blood sugar level has been high for a long period, it may cause changes in the retina leading to diabetic retinopathy. This condition occurs due to blood leakage from the blood vessels in the eyes causing your vision to be blurred.
Yellowing of the sclera (the white part of the eye) can be an indication of liver disease. Jaundice indicates high levels of bilirubin which is made when the liver is inflamed or damaged. Yellowing of the eyes could also suggest other conditions such as cirrhosis or alcoholism, among other conditions.
High blood pressure can cause damage to the retina (hypertensive retinopathy) causing spotting which can be observed during an eye exam. High blood pressure increases the risk of stroke and heart disease.
When a grey-white ring or line of fat deposits forms around the iris it can be an indicator of high cholesterol levels. This condition is known as arcus senilis and though common in old age, it could indicate high cholesterol and triglycerides for people under the age of 40 years. It can also increase the risk of stroke and heart attack.
Eye bags are common, especially due to lack of sleep however, in some situations they may be exophthalmos which is a common sign of Grave’s disease.
A common indicator that you could be having vitamin A deficiency is night blindness. A deficiency in this vitamin reduces rhodopsin pigment which controls the way the eye perceives light.
Allergies such as that caused by pets, can cause a lot of itching which can lead the eyelids to sag. When the eyelids sag, they make the eyes exposed making the eyes very dry.
Cancer can often spread to the eye from other parts of the body. Some people may not know they have cancer until they get a diagnosis from their ophthalmologist. Common cancers that can spread to the eye include breast cancer in women and lung cancer in men.
Fatigue can cause eye twitching; however, at times the twitching could mean you have a nerve disorder such as multiple sclerosis.
Sometimes you may not know that you are stressed until you get an annoying eye twitching and when you see your ophthalmologist, they recommend that you to get a lot of rest and manage your stress better.
The eye is one organ that people tend to neglect until they get diagnosed with more serious conditions. Do not let that be you. Ensure you get yearly eye exams to keep your health in check.
