What’s Wrong With This Picture?

A national study published in JAMA Ophthalmology found that 88% of Americans think that good eyesight is important for overall health. And almost 50% believe that losing sight would have a greater impact on their daily lives than losing a member, their memory, their hearing or their language. 1

According to this same survey, many people are unaware 1 Some of these diseases, such as wet-age-related macular degeneration (AMD) and diabetic retinopathy, among others , affect the part of the eye called the retina, a thin layer of light-sensitive cells and nerve cells located at the back of the eye that allow you to see 2 [19659003] Different conditions, similar symptoms

Retinal diseases are caused by unique changes in the eye. When a person has wet AMD, abnormal blood vessels develop in the part of the retina called the macula, which is responsible for clear, central vision. These new blood vessels can break and leak blood and / or fluid into the macula causing vision problems. 2

Choroidal myopic neovascularization (myopic CNV) is a complication of severe myopia, or pathological myopia. When a person has severe myopia, the eye develops too long back and forth, which leads to areas of the retina that are prone to rupture. As a result, new abnormal blood vessels can enter the retina directly and leave blood and / or fluid in the retina, causing damage and loss of vision. 3

In diabetic eye diseases such as diabetic retinopathy and l & # Diabetic macular edema (DME), existing blood vessels can be damaged and can be damaged. leakage of blood and / or fluid into the retina. In the advanced stages of diabetic retinopathy, new fragile blood vessels can form in the retina, which can easily break, causing bleeding and eventually resulting in distortion or loss of vision 2 [19659005Adarkspotcalledcentralscotomamayappearinthecenterofthevisioncausingadisabilitytoseerightinfrontofit”>A dark spot, called a central scotoma, may appear in the center of the vision, causing an impairment of vision.

Retinal vein occlusion (OVR) occurs when the veins in the eye become clogged, preventing blood and fluid from passing normally through the eye. Blockage can swell the veins and cause blood and / or fluid to flow into the retina, damaging the cells that maintain our vision. 4.5

Although the biological mechanisms of these retinal diseases are unique, some of the symptoms they cause -composed above- are common in all of them and can have a major impact on life. daily.

Getting an annual eye exam is the best way to detect any change in vision. A dilated retinal examination will help diagnose any retinal disease. If you would like more information on these retinal and other diseases, visit www.PreventBlindness.org.
