Aqueous Suppressant Versus Aqueous Outflow on Ocular Blood Flow

Completed

Conditions studied: Glaucoma

In brief

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.

Who can join

Age: 30 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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).

You may not qualify if…

• 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.
