title: Optic neuropathy after epi-LASIK.
abstract: To report a case of optic neuropathy after epi-LASIK.
  
  
  
  A 24-year-old man developed optic neuropathy after epi-LASIK, possibly related to the barotrauma created by the suction ring. Optic neuropathy and steroid-induced ocular hypertension were diagnosed. Prednisolone drops were discontinued and timolol was started.
  
  
  
  After 2 weeks, his symptoms improved and the pain resolved.
  
  
  
  Optic neuropathy is a potentially vision-threatening complication of epi-LASIK. Barotrauma from a transient increase in intraocular pressure created by the suction ring can be an important factor in this entity.
