title: Mucopolysaccharidosis II (Hunter disease) with corneal opacities. Report on two patients at the extremes of a wide clinical spectrum.
abstract: Clinically visible corneal opacities were observed in a patient with an extremely severe form of mucopolysaccharidosis II. In a second patient with an unusually mild form of mucopolysaccharidosis II, discrete corneal opacities were detected by slit-lamp examination. Thus clear corneae can no longer be regarded as a hallmark of mucopolysaccharidosis II.
