Eligibility Criteria

Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • They are unrelated Chinese subjects with high myopia ≦-6.00D. The diagnosis of myopia is determined by the refractive error. Anisometropic individuals, with a refractive error of ≦-6.00 D for one eye and ≦-6.00 D for the other eye, with at least a 2-D difference between the two eyes, are considered unaffected

You may not qualify if:

  • Individuals are excluded if there is known ocular disease or insult that could predispose to myopia, such as retinopathy of prematurity or early-age media opacification, or if they had a known genetic disease associated with myopia, such as Stickler or Marfan syndrome.
