Evaluation of Blood Flow Characteristics in Glaucoma Using Optical Coherence Tomography Angiography (OCT-A).

A Cross-sectional, Prospective, Observational Study to Evaluate Blood Flow Characteristics in Glaucoma Patients Using Optical Coherence Tomography Based Angiography (OCT-A).

The investigators aim to evaluate the efficacy of the new Optical Coherence Tomography based Angiography (OCT-A) softwares in the diagnosis and management of glaucoma.

Inclusion Criteria:

• Diagnosis of open angle glaucoma (OAG) including pseudo-exfoliative and pigmentary glaucoma.
• Documented glaucomatous visual field damage (in the previous 12 months with mean defect (MD) > 2.0 dB)
• Structural and/or functional glaucomatous damage
• Have given written informed consent, prior to any investigational procedures

Exclusion Criteria:

• Patients with allergy to corneal anesthetic
• Patients not able to understand the character and individual consequences of the investigation
• Participation in other clinical research within the last 4 weeks
• Other diseases that may cause visual field loss or optic disc abnormalities
• Refractive error of > +3.00D or < -7.00D
