The purpose of this study is to evaluate rate of progression in newly diagnosed open angle glaucoma with different types of perimetry. Would it be possible to find the rapidly progressing individuals sooner by doing perimetry more often? Is there a difference between different types of perimetry in early glaucoma? What would be the optimal timing of perimetry in newly diagnosed glaucoma? In addition the quality of life in glaucoma patients will be evaluated with two types of questionnaires in three different time points. The enrolled patients will receive appropriate treatment according to glaucoma management guidelines.

Inclusion Criteria:

• Recently diagnosed open angle glaucoma

Exclusion Criteria:

• Significant visual impairment due to another disease (e.g. diabetic retinopathy or maculopathy, cataract, visual field defect after stroke)
• Inability to perform perimetry reliably

Patients referred to Turku University Central Hospital for suspected or newly diagnosed open angle glaucoma
