Teare's disease refers to a type of retinoschisis, which is a condition where the retina splits into two layers. There are no exact synonyms for Teare's disease, but it may also be referred to as hereditary retinoschisis or X-linked retinoschisis. These terms are used because Teare's disease is generally hereditary and is caused by a mutated gene on the X chromosome. Symptoms of the condition include blurred or poor vision, difficulty seeing at night, and the formation of small blood vessels in the retina. While there is no cure for Teare's disease, early detection and treatment can help to slow its progression and preserve vision.
