PVD is a common degenerative change, which affects one or both eyes in many people after middle age. It may present earlier in shortsighted patients or those who have sustained traumas to the eyes.
Thickening of the jelly casts shadows on the retina and are seen as floating shapes. These black “floaters”in your vision move with the eye and then settle as the eye rests. These are often described by patients as a “cobweb” or “insects”.
You may also be aware of flashing lights, like little flickers in the outer periphery. Usually these do not highlight a problem, however, it is important to have the eye thoroughly checked, as occasionally a retinal tear or a retinal detachment may occur.
Myopia
Myopia is a common refractive condition which causes individuals to be near-sighted: they see near objects clearly but distant objects are blurry. Myopia occurs when the cornea and lens focus the light in front of the retina instead of exactly on it. Symptoms of myopia include; difficulty seeing distant objects, squinting frequently, holding books or other objects very close to the face, difficulty seeing writing on signs or watching television and difficulty with driving (particularly at night). Myopia should be diagnosed by a qualified Optometrist, Ophthalmic Surgeon or Eye Specialist. Myopia is best treated with eyeglasses or contact lenses which compensate for the elongated shape of the eye allowing the light to focus properly on the retina. Refractive surgery is another option that eliminates dependence on glasses or contact lenses.
