I enjoyed reading the article on fragile X syndrome (FXS) in the October/November 2011 issue of Neurology Now. In fact, I put the issue on reserve at the University of California at Berkeley library so that my graduate students in the vision lab can read it.

However, I wanted to point out a mistake the author made on page 45. In regard to medical problems faced by people with FXS, she used the term “presbyopia” when she should have used “accommodative insufficiency.” According to the National Eye Institute Web site (, “Presbyopia is a common type of vision disorder that occurs as you age. It is often referred to as the aging eye condition. Presbyopia results in the inability to focus up close, a problem associated with refraction in the eye.”

Children with FXS will develop presbyopia as they reach middle age, but so will 100 percent of all adults who reach middle age. Please make a correction in the next issue for your readers so they will not be misinformed.

Thank you and I look forward to the reading the next issue of Neurology Now.
