Detaljeret beskrivelse
The purpose of this study will be to compare the aqueous production suppressant to aqueous outflow drugs in terms of the response to known vascular parameters. Specifically; systemic perfusion pressure, retrobulbar blood flow and retinal microcirculation.
A comparison of perfusion pressure, retinal microcirculation utilizing Heidelberg Retinal Flowmetry and retrobulbar circulation utilizing color Doppler ultrasound imaging

Beskrivelse
Inclusion Criteria:
Patients will meet all of the following inclusion criteria to enter the study:
- Age: 30 years or older.
Diagnosis: confirmed open-angle glaucoma in at least one eye:
- glaucomatous visual field loss on Humphrey 24-2 or 10-2 perimetry
- glaucomatous optic disc cupping
- agreement between two baseline exams for reliability
- Best corrected visual acuity at least 20/60 in at least one eye.
- Prior Humphrey visual fields demonstrate acceptable reliability standards (see below).
Exclusion Criteria:
- Extensive Humphrey visual field damage consisting of either a mean deviation (MD) < -15 decibels or a clinically determined threat to fixation in both hemifields.
- Evidence of exfoliation or pigment dispersion.
- History of acute angle-closure or a narrow, occludable anterior chamber angle by gonioscopy.
- History of chronic or recurrent inflammatory eye diseases (e.g., scleritis, uveitis).
- History or signs of intraocular trauma.
- Severe or potentially progressive retinal disease such as retinal degeneration, diabetic retinopathy, and retinal detachment.
- Any abnormality preventing reliable applanation tonometry.
- Current use of any ophthalmic or systemic steroid which may interfere with this investigation.
- Cataract surgery within the past year.
- Resting pulse < 50 beats per minute.
- Severe, unstable or uncontrolled cardiovascular, renal, or pulmonary disease.
