Overview

Historical Perspective

Classification

Open-angle Glaucoma
Primary open-angle glaucoma (POAG) (H40.11)
  • not associated with known ocular or systemic disorders that cause increased resistance to aqueous outflow or damage to optic nerve
  • usually associated with elevated IOP
Normal-tension glaucoma (H40.12)
  • considered in continuum of POAG; often used when IOP is not elevated
Juvenile open-angle glaucoma
  • used when open-angle glaucoma diagnosed at young age (typically 10-30 years of age)
Glaucoma suspect (H40.0)
  • normal optic disc and visual field associated with elevated IOP
  • suspicious optic disc and/or visual field with normal IOP
Secondary open-angle glaucoma
  • increased resistance to trabecular meshwork outflow associated with other conditions (e.g. pigmentary-, phacolytic-, steroid-induced-)
  • increased posttrabecular resistance to outflow secondary to elevated episcleral venous pressure (e.g. carotid cavernous sinus fistula)
