One of the saddest facts about most common eye disorders is that they can be prevented if they’re detected early enough. By going for an annual checkup, you can spot the warning signs of some of the most prevalent ocular ailments.
Take a look at some of the leading causes of impaired vision:
Cataracts are the primary cause of reversible blindness worldwide and occur when the eye’s lens becomes clouded, causing loss of vision. There is a myth that this only occurs in the elderly, but it can affect people of all ages – it can even be present in infants. Treatment for the disorder involves surgery and is widely available.
Diabetic Retinopathy (DR)
This occurs as a complication of diabetes. Progressive damage to the blood vessels in the eye causes harm to the light-sensitive tissue that is necessary for vision. DR worsens through four progressive stages. Ignoring the early indicators increases the risk of irreversible damage as the disease progresses and affects both eyes.
Glaucoma is an all-encompassing term used to refer to a group of eye diseases that damage the optic nerves. The results of this can be very serious – ending in blindness or severely impaired vision. This condition is caused when fluid pressure in the eyes rises.
If detected early, glaucoma can be managed through the use of medication or, in very severe circumstances, surgery.
Age-Related Macular Degeneration (AMD)
AMD tends to arise when the eyes slowly degenerate with age. Interestingly, this disorder manifests in two different ways: wet and dry.
The former occurs when an abnormal blood vessel behind the retina starts to grow. This causes damaging blood and fluid leakage. An early symptom of wet AMD impaired vision is that straight lines appear wavy.
Dry AMD occurs because of a progressive thinning of cells in the retina, which results in blurred central vision. This form is more common, and accounts for 70–90% of cases. The effects of AMD can be managed by avoiding smoking, eating a healthy diet rich in vitamins and minerals, and regular exercise.
When it comes to your vision, there may be genetic factors that lead to unavoidable health issues. However, playing an active role in changing your lifestyle and going for regular checkups can nip very dangerous possibilities in the bud, and protect your windows to the world.
