Neurofibromatosis (NF) is a genetic disorder that can cause skin changes as well as tumors to grow along the nerves throughout the body. Other issues like learning disabilities, scoliosis, attention deficit disorder, cancer, and high blood pressure are a few of the problems that could occur in NF. There is currently no cure.
Lisch nodules are the most common ocular manifestations of Neurofibromatosis type 1 (NF1). They consist of melanocytic hamartomas, the color usually being brown or yellow. They are evident as round elevations on the surface of the iris (blue arrows). They might be seen by the naked eye, but the best way to evaluate them is with slit-lamp examination.
