title: Chronic clinical course of two patients with severe corneal dystrophy caused by homozygous R124H mutations in the betaig-h3 gene.
abstract: OBJECTIVE
  To report the chronic clinical course of two patients with homozygous R124H mutations in the betaig-h3 gene.
  
  
  METHODS
  Case reports.
  
  
  RESULTS
  Two patients with homozygous R124H mutations in the betaig-h3 gene developed severe juvenile corneal opacities that required keratoplasty. After surgery, corneal opacities recurred and limited the recovery of visual acuity in the chronic follow-up.
  
  
  CONCLUSIONS
  In patients with homozygous R124H mutations in the betaig-h3 gene, recurrence of corneal opacities after keratoplasty limits the recovery of visual acuity in the chronic follow-up.
