What is the esterman efficiency score?
The mean Esterman efficiency score was 92±12, with a maximum score of 100. Patients generated a score of 62±17 when asked to subjectively assess their own vision.
What is the esterman visual field?
Esterman visual field perimetry is a binocular testing method which is also available on the HFA. The test consists of 120 white test points shown with equal, non-adjustable suprathreshold light intensity of 10 dB and examines more than 130° of the field.
How do you read visual field results?
Use this order to interpret your Humphrey visual field every time:
- Confirm it’s the right patient with name and date of birth.
- Confirm it’s the right/left eye.
- Look at the reliability indices.
- Look at the pattern.
- Look at the GHT, mean deviation, VFI, and pattern standard deviation.
- Compare to the previous visual fields.
What is a good field of vision?
A normal visual field is an island of vision measuring 90 degrees temporally to central Fixation, 50 degrees superiorly and nasally, and 60 degrees inferiorly. Visual acuity increases from movement discrimination in the extreme peripheral vision to better than 20/20 in the center of vision.
What is a 30 2 visual field test?
30-2: Measures 30 degrees temporally and nasally and tests 76 points. Used for general screening, early glaucoma and neurological conditions.
What do the numbers on a visual field test mean?
The visual threshold is the intensity of stimulus seen 50% of the time at each location. The threshold values of each tested point are listed in decibels in the sensitivity plot. Higher numbers mean the patient was able to see a more attenuated light, and thus has more sensitive vision at that location.
What is 70 degree field of vision?
The normal (monocular) human visual field extends to approximately 60 degrees nasally (toward the nose, or inward) from the vertical meridian in each eye, to 107 degrees temporally (away from the nose, or outwards) from the vertical meridian, and approximately 70 degrees above and 80 below the horizontal meridian.
What is a result of poor peripheral vision?
Peripheral vision loss (PVL) occurs when you can’t see objects unless they’re right in front of you. This is also known as tunnel vision. Loss of side vision can create obstacles in your daily life, often impacting your overall orientation, how you get around, and how well you see at night.
What is a 24-2 visual field test?
The visual field (VF) pattern most widely used to detect glaucomatous damage, the 24-2 test pattern, does not adequately test the macular region, as the 6° grid of the 24-2 pattern has only four points within ± 8°.
How to perform Esterman visual field?
esterman visual field perimetry is a binocular testing method which is also available on the hfa, the test consists of 120 white test points shown with equal, visual field testing is performed one eye at a time, or five fingers from each hand in two visual field quadrants and ask the subject to count the fingers, to do this test, essentially …
What do the results of the visual field test mean?
What do the results of the visual field test mean? The visual field test is a way to evaluate the peripheral vision sensitivity of an eye. It uses a very small test light that can vary in brightness. This determines how well and how far out to the side this small intensity of light can be seen. A healthy eye can see tiny, low intensity lights
How to interpret visual fields?
Introduction: Components of Vision.
What is an Esterman binocular field test?
• The binocular Esterman visual field test is most commonly run on the Humphrey Visual Field Analyzer. • It is a supra-thresholdtest that presents a single, very bright stimulus (10dB) at each of 120 locations within the visual field. • The subject is required to fixate centrally and press a button when a stimulus is detected.
