Workup

Laboratory Studies

  • Genetic analysis performed in research labs can reveal the genetic mutation of lattice corneal dystrophy. This is not a routine study at this time.
  • A genetic analysis can determine the specific mutation on the BIG H3 gene of chromosome 5, which can allow for the precise diagnosis of the subtype of lattice dystrophy and can be useful for differentiating lattice dystrophy from Avellino dystrophy, granular dystrophy, and Reis-Bückler dystrophy (all which have mutations of the BIG H3 gene).

Procedures

  • Corneal biopsy (which would never be indicated clinically) would reveal amyloid in the corneal stroma.

Histologic Findings

The deposits are amyloid, which stain orange-red with Congo red. They also stain with periodic-acid Schiff (PAS) and Masson trichrome. Under polarized light, the deposits exhibit birefringence and red-green dichroism.
