Portable Vision Screener plusoptiX S12C

Plusoptix provides binocular, hand-held vision screening devices, especially for infants, children and uncooperative patients.

Studies show that the best visual outcomes depend on the early detection and treatment of vision disorders. Therefore, paediatric ophthalmologists recommend annual vision screening for all children starting ideally at the age of one year. If there is a family history of eye disorders, earlier screening is advised at the age of 6 to 8 months old.

Conventional visual acuity testing can only be performed in older, cooperative children.

Two healthy eyes are critical to a child’s well-being and development. A visual disorder compromises social and scholastic achievement, can be dangerous in traffic and restrict occupational choices later in life.

The Plusoptix device provides an accurate measurement within seconds. Measurement results are compared to age-specific thresholds, and a “Pass” or “Refer” vision screening result is displayed.

A “Refer” vision screening result will mean the patient should consult an eye care professional for further advice.

Plusoptix Screening Devices

The Plusoptix S12 range of devices detects refractive errors and eye misalignment, which are the most common causes of amblyopia (lazy eye).

Measurements are non-invasive, requiring no physical contact with the child. A sound target attracts fixation, and no further cooperation is required to perform a measurement.

Features

  • Binocular readings
  • Measurement results are compared to age specific thresholds and a “Pass” or “Refer” vision screening result is displayed

  • Measurement from 1m distance to the child
  • Measurement in less than one second
  • Can be used in undilated pupils
  • Fully automated function
  • Children can be measured starting at 6 months of age
  • Measurement is delegable and can easily be performed by a trained assistant
  • Child friendly design
  • Possibility to measure over glasses and contact lenses

The measuring principle is based on eccentric photoretinoscopy: infrared light is projected through the pupils onto the retina. Depending on the refractive error, the reflected light forms a specific brightness pattern within the pupil. The spherical refraction is calculated based on this crescent pattern. To determine cylinder and axis, the same measurement is repeated in three meridians. The measurement with infrared light is completely innocuous. Infrared light is also contained in daylight and not visible.

Screening Results

Plusoptix vision screening devices provide reliable measurement values of:

  • Refraction (spherical equivalent)
  • Pupil diameter and pupil distance
  • Symmetry of corneal reflexes

With these measurement values it is possible to detect the following most prevalent childhood vision disorders that may lead to the development of amblyopia (lazy eye) including:

  • Hyperopia (farsightedness)
  • Myopia (nearsightedness)
  • Astigmatism (blurred vision)
  • Anisometropia (unequal refractive power)
  • Anisocoria (unequal pupil size)
  • Strabismus (eye misalignment)

With the determined measurement values compared to age specific thresholds, a “Pass” or “Refer” vision screening result is displayed. Children with a “Refer” result need to be sent to an eye care professional for an eye examination.
