title: A case of Schnyder corneal dystrophy with crystals.
abstract: OBJECTIVE
  To report a rare corneal dystrophy and its common findings to help aid others in proper and early diagnosis and management.
  
  
  METHODS
  A 56-year-old male patient presented with the concern of blurry vision in both eyes that has progressed over the last 10 years. Anterior segment examination revealed arcus with a central haze in both eyes and crystalline deposition in the right eye. A diagnosis of Schnyder corneal dystrophy was made based on clinical presentation.
  
  
  CONCLUSIONS
  Schnyder corneal dystrophy is rare but has different presentations and may actually be misdiagnosed. The clinical signs change as the patient ages causing a decrease in vision, which may necessitate referral for phototherapeutic keratectomy, penetrating keratoplasty or deep anterior lamellar keratoplasty. The patient's systemic findings that correlate with the dystrophy need to be assessed and managed appropriately.
