Refractive disordersThe 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 problemsBecause 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.AstigmatismAstigmatism 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 eyeGlaucoma• 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 restrictedHyperopiaHyperopia 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 PigmentosaRetinitis 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​Hence, the correct match is:Set-I(Terms)Set-II(Description)Astigmatism Result in blurred vision, caused by an uneven curve of cornea or lens of the eyeGlaucomaIt occurs when the flow of fluids in the eye is restrictedHyperopiaIt is most commonly known as farsightedness, results from the failure of the corneaRetinitis Pigmentosa It is a hereditary disorder that causes degeneration of retina
