How many people are affected ichthyosis

Condition analysis:
Most varieties of ichthyosis affect only one person in several tens of thousands. Ichthyosis vulgaris is the exception. It appears in approximately one person in every 80 and often goes undiagnosed because it can be relatively mild.

Instructions:
Treatments for ichthyosis often take the form of topical application of creams and emollient oils, in an attempt to hydrate the skin. Retinoids are also used for some conditions. Exposure to sunlight may improve or worsen the condition.

There can be ocular manifestations of ichthyosis, such as corneal and ocular surface diseases. Vascularizing keratitis, which is more commonly found in congenital keratitis-ichythosis-deafness (KID), may worsen with isotretinoin therapy. Ectropion, if it occurs, can be treated surgically after skin hydration.
