PERIMETRY Meaning and Definition

  1. Perimetry is a diagnostic test used in the field of ophthalmology to assess a person's visual field, which is the entire area that can be seen when the eyes are fixed on a central point. It involves the measurement of the boundaries and sensitivity of an individual's visual field, including the peripheral vision.

    During perimetry, the patient is typically seated in a dark room and asked to fixate on a target, such as a small light in the center of a bowl-shaped instrument called a perimeter. The instrument then emits small points of light at various locations within the bowl, and the patient must indicate when they see the light by pressing a button or verbally responding.

    The results of a perimetry test are recorded and analyzed, allowing a comprehensive assessment of a person's visual field. This information is valuable for detecting and monitoring diseases and conditions that may cause vision loss, such as glaucoma, retinal disorders, or brain abnormalities. By mapping the visual field, perimetry enables the identification of any blind spots, decreased sensitivity, or alterations in visual perception.

    Perimetry is a precise and objective method used to monitor the progression of visual field defects and allows for early detection of potential problems. It is an important tool for ophthalmologists and optometrists to make accurate diagnoses, determine treatment plans, and evaluate the effectiveness of therapeutic interventions targeting visual field complications.

  2. The determination of the limits of the visual field.
