Retinal tumours in neurofibromatosis.

A 45-year-old male with von Recklinghausen's disease was noted to have hamartomatous lesions of the retinae similar to those more commonly described in Bourneville's disease and von Hippel-Lindau's disease. These findings would appear to support the concept that the retinal changes in neurofibromatosis occupy an intermediate position between those seen in the other two phakomatoses.
