Klippel-Trènaunay-Weber (KTW) syndrome is a condition characterized by: port-wine stains or birthmark malformations in the skin, soft tissue and bony growths (generally involving a limb), and vascular anomalies (varicose veins). Although these three symptoms are consistently found in patients with Klippel-Trènaunay-Weber syndrome, there are other symptoms, which include atrophy (a limb that is underdeveloped), fingers and toes that are disproportionately large or small, digits that are webbed (syndactyly), too many digits (polydactyly), or too few digits (oligodactyly). The cause of Klippel-Trènaunay-Weber syndrome is not known. However, recently there have been some cases that run in families. There is no significant treatment for Klippel-Trènaunay-Weber syndrome.

The condition is diagnosed by having an eye exam and can be treated by wearing glasses or contact lenses or by having refractive surgery.
-
Myopia
Myopia, or nearsightedness, makes it difficult to focus on objects that are far away.

Women should wait at least three months after receiving the vaccine before trying to get pregnant.

-
Scleritis
Scleritis is inflammation of the white part of the eye. It may be caused by a serious underlying condition, such as an autoimmune disease. Symptoms include redness, pain, tearing, sensitivity to light, and decreased visual acuity. Treatment may include eyedrops as well as treatment for any underlying disease process. Scleritis cannot be prevented.

Heterochromia Iridis
Heterochromia iridis is a rare condition that describes people with two different colored eyes. There are many potential underlying causes of heterochromia iridis including genetic and acquired conditions. Heterochromia iridis comes in three types: sectorial heterochromia, central heterochromia, and completely heterochromia. The condition is often recognized by a parent (in the case of an affected infant) or by the patient or a family member (acquired heterochromia iridis). Treatment includes addressing the underlying condition or wearing tinted contact lenses to make the eyes look more uniform. The majority of people with heterochromia iridis have an excellent prognosis.
