Eye Ailments and its Care

The Eye is like a camera. Images from the objects you look at passes through the crystalline lens in the front of your eye and falls at the back of your eye - the Retina. From retina the images are then carried to the brain where the wonderful sensation of vision takes place. In cataract, the human crystalline Lens become opaque and images are blurred as light cannot pass through it. The eye loses the power of vision and the only technique by which you can regain your lost vision is by surgery, replacing the opaque crystalline lens with an artificial intraocular lens.

It is the second largest blinding disorder, after cataract, increasing rapidly with population growth and life expectancy.Glaucoma is a disease of complex multifactorial optic neuropathy with progressive loss of retinal ganglion cells atrophy of the optic nerve. The pressure of the eye usually rises and by surgery an alternative pathway is made through which the excess amount of the fluid that accumulates inside the eye can flow out. Success of operation depends on its stage and severity. Glaucomatous field defect is irreversible and sometimes it is necessary to repeat the surgery.

Diabetic Retinopathy:Diabetic Retinopathy
Diabetic Retinopathy literally means "Damage" to the retina by Diabetes. In fact vision loss is 25 times more common in persons with diabetes than in those without diabetes. The longer a person has diabetes, the greater is the risk of vision loss.If Diabetes is diagnosed before 30 years of age, the incidence of Diabetic Retinopathy after 10 years is 50% and after 30 years is 90%. Diabetes Mellitus is the leading cause of new cases of legal blindness among working age adults.
Fortunately, blindness from diabetic retinopathy is often preventable if diagnosed early.

Red Eye:
Red eyes disease is one of the disorders which affect the eyes. It makes the eyes red and sticky. It spreads easily from person to person and is common among children. It is caused by certain germs which enters the eye from direct contact,e.g., a person touches the pus (sticky substance) in the eye of a child who has the disease and rubs his own eye with the same hand without washing it, using the same towel or clothes of someone who has the infection, house flies etc.

Refractive Error:
Refractive errors are disorders, not diseases. It means that the shape of your eye does not bend light correctly, resulting in a blurred image. Light has to be refracted or bent by the cornea and the lens to the retina, in order for us to see. The main symptoms of Refractive Error are Blurred vision, Difficulty reading or seeing up close things, Crossing of the eyes in children. Refractive disorders are commonly treated using corrective lenses, such as eyeglasses or contact lenses. Refractive surgery can also be used to correct some refractive disorders.

Amblyopia, also known as lazy eye, is a disorder of the visual system that is characterized by poor or indistinct vision in an eye that is otherwise physically normal, or out of proportion to associated structural abnormalities. Many people with amblyopia, especially those who are only mildly so, are not even aware they have the condition until tested at older ages, since the vision in their stronger eye is normal. However, people who have severe amblyopia may experience associated visual disorders, most notably poor depth perception.
Amblyopia can be caused in many ways such as, deprivation of vision early in life, vision-obstructing disorders such as congenital cataracts or by anisometropia.
