Welcome to the Plusoptix Amblyopia Screening monthly blog where readers can learn more about the importance of amblyopia screenings and follow-up eye exams in early childhood as well as other key topics related to kids’ eye health.

Vision screening that requires a child to respond to an eye chart has been shown to have poor predictive value, especially in the first 3 to 4 years of life.(1) Instrument-based vision screening, however, can detect abnormalities that could lead to permanent vision loss. Plusoptix, founded in 2001, is dedicated to the development of binocular handheld photorefractors for babies, children, and uncooperative patients. Plusoptix vision devices screen for hyperopia, myopia, astigmatism, anisometropia, anisocoria, and strabismus. A number of these conditions are considered risk factors for amblyopia, which can cause partial or full blindness if not treated. The goal of amblyopia screening is to detect vision disorders in the first few years of life and to and treat early when therapy has the best chance of being successful.

Good vision is fundamental to children’s educational, physical, and social development, yet researchers say US prevalence data shows an “astonishing” number of undiagnosed vision problems in preschoolers. In 2015, more than 174,000 children aged 3 to 5 years visually impaired with 69% from a simple uncorrected refractive error, and 25% from bilateral amblyopia.(2)

In this space, Plusoptix will bring together contributors from eye care professionals to volunteers to school nurses who will also explore timely topics such as vision tests and learning, as well as other timely topics such as UV safety and screen time for children, and diabetic eye disease.

Prioritizing vision care will help ensure all children have a chance to reach their full potential.

We look forward to continuing to empower  primary health care providers in their quest to detect most prevalent vision disorders as early as possible.

  1. While at meeting of the Lake Sumter Lions Club on Wednesday, July18th, the club mentioned they had purchased a PlusOptix scanner . I’d understand this device is superior to the Spot Camera. Please provide any information about the device along with @ cost of one.

    Thank you,
