Online Guide to Get View On Common Retinal Disorders

1. THE RETINA AND ITS DISORDERS

2. RETINA DEFINITION, FUNCTION AND FACTS: The retina is a thin layer of tissue that resides in the back of the eye on the inside. It is located near the optic nerve and it is responsible for receiving light that lens has focused, convert the light into neural signals and send these signal on to the brain for visual recognition. In case if you don’t have healthy retina then you can’t read, drive or see the final details. There are retinal disorder or disease affects your retina, which, in turn, can affect vision to the point of blindness. Common retinal conditions include floaters, macular degeneration, diabetic eye disease, retinal detachment, and retinitis pigmentosa.

3. EYE FLOATERS AND FLASHES Floaters: In this type of eye disorder there is appearance of small specks, dots, circles, lines or cobwebs in your field of vision. These seem to be in front of your eye, they are floating inside. Floaters are tiny clumps of gel or cells inside the vitreous that fills your eye. What you see are the shadows these clumps cast on your retina. Flashes can look like flashing lights or lightning streaks in your field of vision

5. AGE-RELATED MACULAR DEGENERATION Age-related macular degeneration (AMD) is an eye disorder that may get worse as we get older. It's the leading cause of severe, permanent vision loss in people over age 60. In this condition the small central portion of your retina, called the macula, wears down. Symptoms: Visual distortions, such as straight lines seeming bent Reduced central vision in one or both eyes The need for brighter light when reading or doing close work Increased difficulty adapting to low light levels, such as when entering a dimly lit restaurant Increased blurriness of printed words Decreased intensity or brightness of colors Difficulty recognizing faces

7. Diabetic Retinopathy It is a diabetes complication that affects eyes. It's caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). At first, diabetic retinopathy may cause no symptoms or only mild vision problems. Diseases or conditions caused: Blindness Risk Factors: Diabetes; Tobacco smoking

9. RETINAL DETACHMENT Retinal detachment is an emergency. Tissue at the back of the eye pulls away from a layer of blood vessels that provide necessary oxygen and nourishment. The appearance of many bits of debris (floaters), sudden flashes of light, or a shadow in the vision field are symptoms. Prompt medical treatment can often save vision in the eye.

11. RETINITIS PIGMENTOSA Retinitis pigmentosa (RP) is a group of rare, genetic disorders that involve a breakdown and loss of cells retina — which is the light sensitive tissue that lines the back of the eye. Coin the mmonsymptoms include difficulty seeing at night and a loss of side (peripheral) vision.
