Eye as an Organ - Essay Example

The aqueous humor is a clear fluid enclosed in the frontal chamber between the cornea and the iris and an uncovered part of the lens. The lens is located in the ciliary body, attached to suspensory muscle; it is formed by fine translucent filaments. The vitreous body, the posterior chamber, is a transparent jelly that is somewhat bigger as compared to the aqueous humor; it is positioned at the rear side of the lens and is surrounded by the sclera.

Glaucoma is an eye infection in which the regular fluid pressure within the eyes increases gradually, causing loss of sight. It is normally treated with eye drops, but surgery is also advised in some cases where drug treatment is not successful.

Diabetic retinopathy is a very common diabetic eye disease and the main reason for blindness in grown-ups. Variations in the retina’s blood vessels are the cause of this disease. Generally, treatment usually does not cure diabetic retinopathy; however, strict control of blood sugar will lessen the risk of vision loss (Samii & Jannetta, 2012). Another common visual impairment is myopia, in which distant objects seem blurred. It can be treated with glasses, contact lenses, or corrective surgery.
