What does Plusoptix test for?
The PlusoptiX S12 is a photoscreener that uses infrared and wavefront technology to perform binocular non-cycloplegic autorefraction within seconds from a distance of 1 m. Its accuracy to detect myopia, astigmatism, anisometropia, and hyperopia is discussed elsewhere [8,9,10,11,12].
How accurate is Plusoptix?
Measurements success rates were 97% for Spot and 54% for Plusoptix. Comparing the Spot and the Plusoptix, sensitivity was 96% versus 100%, specificity was 87% versus 61%, PPV was 90% versus 76%, and NPV was 94% versus 100% for detection of refractive error.
How does Plusoptix vision screener work?
Plusoptix Vision Screeners use the measuring principle of a transillumination test. Unlike other transillumination tests (e.g. Red Reflex test), Plusoptix vision screeners avoid glare of the patient, by using infrared light. The pupils remain large even without dilation.
What is Anisometropia?
Anisometropia means that the two eyes have a different refractive power (glasses prescription), so there is unequal focus between the two eyes.
What causes gaze asymmetry?
The causes of eye misalignment are various, and sometimes unknown. Potential causes include high farsightedness, thyroid eye disease, cataract, eye injuries, myasthenia gravis, cranial nerve palsies, and in some patients it may be caused by brain or birth problems.
What vision is better 20 20 or 20 15?
A person with 20/20 vision is able to see letters 1/10th as large as someone with 20/200 vision. 20/20 is not the best possible eyesight however, for example, 20/15 vision is better than 20/20. A person with 20/15 vision can see objects at 20 feet that a person with 20/20 vision can only see at 15 feet.
What causes misaligned eyes in adults?
Stroke (the leading cause of strabismus in adults) Head injuries, which can damage the area of the brain responsible for control of eye movement, the nerves that control eye movement, and the eye muscles. Neurological (nervous system) problems. Graves’ disease (overproduction of thyroid hormone)
When to use the plusoptix vision screener for children?
Vision Screener Plusoptix vision screeners can detect vision disorders and media opacities starting at 5 months of age and up A Plusoptix vision screener empowers Pediatricians, Head Start offices, Lions Clubs, Kid Sight Programs, and School nurses to detect the most prevalent vision disorders in children starting age 5 months and up.
When did the plusoptix photoscreener first come out?
plusoptiX – The plusoptiX photoscreener was first commercially available in 1995. The device uses an infrared video recorder to obtain images on 3 axes. The device produces a non-cycloplegic autorefractive reading, which is then compared to pre-set referral criteria.
Can a lazy eye be detected by a plusoptix test?
The earlier a vision disorder or media opacity is detected the better it can be treated, and Amblyopia, i.e. a lazy eye, can be prevented. Plusoptix Vision Screeners use the measuring principle of a transillumination test.
Which is the best spot vision screener for kids?
Below, we compare the top photoscreeners using four main components: workflow efficiency, clinical efficacy, cost over time, and modernized security. Those photoscreeners are Plusoptix, GoCheck Kids, Spot Vision Screener, and iScreen Vision.
