To illustrate a good visual outcome following penetrating keratoplasty in a patient with Sly disease, a rare mucopolysaccharidosis (MPS) caused by a deficiency of beta-glucuronidase.
A 15-year-old male with progressive bilateral corneal opacification had a complete medical, genetic, and ophthalmic evaluation followed by a penetrating keratoplasty.
The cornea has remained clear for two years following surgery. Histopathology of the corneal button demonstrated vacuoles and granular inclusions consistent with this lysosomal storage disease.
While research is ongoing in the fields of enzyme replacement and bone marrow transplantation, these treatments may not alleviate or reverse the corneal clouding. This case illustrates that cornea transplantation may be a valuable treatment option for visually rehabilitating such patients.
