visuALL Field Analyzer (vFA) Compared to Standard Humphrey Automated Perimetry

Completed · Not applicable

Conditions studied: Glaucoma, Open-Angle

In brief

To determine age-adjusted reference values of the visuALL Field Analyzer (vFA) retinal sensitivity and to assess the repeatability of the measured values and compare them with those measured by a Standard Automatic Perimetry (SAP).

Who can join

Age: 21 and older, up to 80. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• age 21 to 80 years
• Healthy subjects with no eye diseases, normal appearing optic nerve and retina, intraocular pressure less than 19 millimeters mercury and normal standard automatic perimetry (SAP).
• mild glaucoma subjects with less than -6 mean deviation
• moderate glaucoma subjects with -6 to -12 mean deviation

You may not qualify if…

• spherical refraction outside ± 3.0 diopters and cylinder correction outside 2.0 diopters
• Unreliable SAP (false positives, fixation losses and false negatives greater than 25% and/or observable testing artifacts)
• Unreliable visuALL Field Analyzer (vFA) (greater than 25% false positive, excessive fixation losses)
• SAP abnormality with pattern loss consistent with neurologic and/or other ocular diseases than glaucoma
• Intraocular surgery in study eye (except non-complicated cataract or refractive surgery performed more than 6 months before enrollment and without posterior capsule opacification)
• History of systemic condition known to affect visual function
• History of medication known to affect visual function
