Exfoliation syndrome is the most common cause of lens subluxation worldwide. Younger patients with anterior lens displacement often have underlying causes, such as ciliary block, Weill–Marchesani syndrome and Marfan syndrome. The latter is the most common cause of hereditary ectopia lentis.
Why do people’s eyes move side to side?
