入选标准
- •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.
排除标准
- •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.
