Atopic dermatitis is a skin condition that most often appears in childhood. It is related to environmental allergies, hay fever, and asthma, meaning that if you develop one of these conditions, you are more likely to develop the other conditions. Atopic dermatitis is an immune response. Typically, an irritant (called the "precipitant" or immediate cause) comes into contact with your body. The body gets confused and overreacts, causing inflammation of the skin even in areas that weren't exposed. If you develop acute (short-term) eczema, you may see small, red, itchy bumps on your skin. There might also be some swelling and scaling. If the eczema continues, the symptoms may reach the chronic stage, developing into itchy, thicker patches of skin that turn brownish or reddish. In addition, the bumps may weep, meaning they produce liquid. You may also have scaly, dry skin. Atopic dermatitis can come and go over time. When the symptoms are worse, it's called a flare-up. However, you can go for long periods when you may exhibit no symptoms. This condition is not contagious, meaning you can't catch it by coming in contact with someone who has it. However, it can be passed genetically from parent to child. This condition can cause problems with your vision. If you think your vision is being affected by a recent flare-up, always speak with your doctor. One way it affects your vision is the skin around your eyes can be red and puffy, making it difficult to see. However, this disease has also been linked to a higher occurrence of cataracts and spontaneous retinal detachment, even when treated.
