Common Cornea Disorders
There are some common eye disorders that are caused by the abnormal shape of the eye. One such condition is ectasia, a disorder that causes the cornea to bulge outward. LASIK surgery causes this by weakening the cornea. Other, naturally caused disorders include keratoconus and astigmatism. Keratoconus is caused when the cornea thins, causing it to bulge outward in a cone shape. Astigmatism, on the other hand, is a result of the cornea or lens curving in a different direction.
Common Optic Nerve Disorder
Another eye condition that afflicts many different people is glaucoma. This condition is different from other common conditions in that it is caused by elevated eye pressure. This pressure can result in damage to the optic nerve, which in turn can lead to vision loss.
Signs of an Eye Disorder
Although each eye condition is different and might manifest itself in a different way, there are some common signs that point to an eye disorder. If you notice any type of vision loss or blurring, make an appointment with an optometrist for an eye exam. Other common symptoms associated with these conditions could be eye pain, sensitivity and even headaches and nausea.
