Campimeter
Campimeter
Campimeter (pronounced: kam-pim-i-ter) is a medical instrument used in ophthalmology to measure the field of vision for a fixed position of the eye.
Etymology
The term "campimeter" is derived from the Greek words "kampe" meaning bend or curve, and "metron" meaning measure.
Usage
A campimeter is primarily used to detect and measure scotoma, or blind spots, in the visual field. It is a crucial tool in diagnosing and monitoring conditions such as glaucoma, macular degeneration, and retinal detachment.
Procedure
During a campimetry test, the patient is asked to fixate on a central point within the campimeter. Light stimuli of varying intensities are then presented in different parts of the visual field. The patient's responses to these stimuli are recorded and used to map the visual field.
