Goldmann perimetry
Pronunciation: GOLD-man per-ih-MEH-tree
A manual kinetic visual field testing method using moving light stimuli to map the peripheral visual field boundaries.
Full Definition
Goldmann perimetry is a kinetic visual field testing technique that uses a bowl-shaped instrument to present moving light targets of varying size and brightness from the periphery toward the center of vision until the patient detects them. This method is particularly valuable in pediatric ophthalmology because it can be adapted for young children who may have difficulty with static automated perimetry. The test maps isopters (areas of equal visual sensitivity) and can detect both central and peripheral visual field defects. Results are plotted on standardized charts using specific notation for target size and luminance, making it essential for monitoring conditions like optic pathway gliomas or cortical visual impairment.
Usage
Usage note: Capitalize Goldmann as a proper noun; specify target notation when documenting results.
