Refractive disorders

  • The most common types of refractive disorders include:
  • myopia (nearsightedness),
  • hyperopia (farsightedness),
  • astigmatism, in which the eye doesn't focus light evenly on the retina, and presbyopia, an age-related condition in which the eye's lens can no longer change shape enough to allow the eye to focus clearly up.

Retinal and optic nerve problems

  • Because the inner retinal cells, including the retinal ganglion cells, may be destroyed in these diseases (inner retinal or whole retinal), prosthetic devices that stimulate the inner retina may not be effective.
  • Common optic nerve diseases include glaucoma, optic neuritis, and ischemic optic neuropathy.

Astigmatism

  • Astigmatism is a type of refractive error in which the eye does not focus light evenly on the retina.
  • This results in a distorted or blurred vision at any distance. 
  • Other symptoms can include eyestrain, headaches, and trouble driving at night.
  • Result in blurred vision, caused by an uneven   curve of cornea or lens of eye
Glaucoma
  • • Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision.
  • • This damage is often caused by abnormally high pressure in your eye. 
  • • Glaucoma is one of the leading causes of blindness for people over the age of 60.
  • It occurs when the flow of fluids in the eye is restricted

Hyperopia

  • Hyperopia is known as farsightedness.
  • It is a refractive error, which means that the eye does not bend or refract light properly to a single focus to see images clearly.
  • In hyperopia, distant objects look somewhat clear, but close objects appear more blurred.
  • It is most commonly known as farsightedness, which results from the failure of the cornea.

Retinitis Pigmentosa

  • Retinitis pigmentosa is a genetic disorder of the eyes that causes loss of vision.
  • Symptoms include trouble seeing at night and decreased peripheral vision.
  • As peripheral vision worsens, people may experience "tunnel vision".
  • It is a hereditary disorder that causes degeneration of the retina

Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.
The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. The sense perception that the brain releases after the eye converts light to nerve impulses is known as
