Ages Eligible for Study:   19 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Subjects 19 years of age and older with normal eyes and with ocular disease.

Inclusion Criteria:

  • Subjects must be 19 years of age and older

Exclusion Criteria:

  • Corneal diseases including corneal transplants, corneal dystrophies, or trauma to the cornea that may prevent reliable tonometry of either eye.
  • Intolerant to topical Proparacaine and Benoxinate
  • Pregnant or nursing
  • 18 years of age and younger.
  • Physical limitation preventing ability to obtain reliable intraocular measurements (e.g. difficulty positioning subjects in front of the slit lamp or inability to keep eyes open during the intraocular pressure checks).
