Brief Summary:
The Erlangen Glaucoma Registry is a clinical registry for cross sectional and longitudinal observation of patients with open angle glaucoma (OAG) or glaucoma suspect, founded in 1991. The primary aim is the evaluation of diagnostic and prognostic validity of morphometrical, sensory and hemodynamical diagnostic procedures. No therapeutic studies are performed.

Condition or disease
Primary Open Angle Glaucoma Secondary Open Angle Glaucoma Ocular Hypertension

Detailed Description:
Purpose: Detection of onset and progression of structural and functional damage due to glaucoma. Determination of rate and amount of progressive change due to glaucoma. Characterisation of the relationship between structural and functional change over time. Evaluation of predictive factors for the development and progression of glaucoma.
