title: Glaucoma screening: current perspectives and future directions.
abstract: BACKGROUND
  Glaucoma is an optic neuropathy with characteristic progressive optic nerve degeneration. Early detection and treatment may prevent blindness; however, the value of glaucoma screening has been debated.
  
  
  METHODS
  Articles pertaining to glaucoma screening were reviewed.
  
  
  RESULTS
  In reviewing the glaucoma literature, there is a lack of a sensitive and specific screening test and concerns over cost-effectiveness. Methods of screening include population-based screening and opportunistic case finding, which both have advantages and disadvantages.
  
  
  CONCLUSIONS
  Additional research is needed to better understand glaucoma progression as well as to identify improved screening tests. Consideration must be given not only to the feasibility of performing a glaucoma screening, but also to the follow-up and long-term care for glaucoma patients.
