Nevusby Scott Pautler, MD
What is a choroidal nevus? A choroidal nevus pigmented spot found under the retina and is seen in about one in twenty patients examined. The retina in your eye is like the film inside a camera. A choroidal nevus is similar to a freckle or mole seen on the skin. Does a choroidal nevus cause visual problems? Rarely does a choroidal nevus cause symptoms, which may include burred vision and distortion of straight lines. The eye doctor can determine if these symptoms are due to a nevus and recommend treatment, if necessary. What is the long-term concern with a choroidal nevus? Very rarely, a choroidal nevus will grow or change into a melanoma. Choroidal melanoma is a type of cancer of the eye that can cause loss of vision and spread to areas outside the eye, threatening loss of life. What should be done about a choroidal nevus? The most important step is to have a thorough dilated eye examination. The eye doctor will check for the presence of changes that may indicate that a particular nevus is at high risk of growing. Early diagnosis and treatment of choroidal melanoma with radiation may preserve vision and save lives. Fortunately, most choroidal nevi remain stable without growth and without visual symptoms, and need not be treated. Regular eye examinations and periodic photographic documentation are helpful to observe choroidal nevi for important changes that a patient may not be able to detect. What should I be on the lookout for? It is not likely that any symptoms will develop. Nevertheless, report for examination if any of the following symptoms occur: new onset of persistent blurring of vision, a blind spot in the vision, straight lines look wavy or curved, loss of side-vision (peripheral vision).
