Identifying Vision Problems in Young Children

The aim of vision screening is to identify amblyopia (lazy eye) and vision loss. Identifying vision problems as early possible is important because undetected vision problems can reduce school achievement, harm the development of hand-eye coordination and lead to a lifelong reduction in vision.

Many countries have local and national vision screening programmes for pre-school children around the age of 5. In the US vision screening is also undertaken by General Practice Paediatrician's.

Objective Acuity ("OAL") is developing the first objective vision screening test based on visual acuity for children under the age of 5.

Currently, vision disorders is the most prevalent, disabling condition among children.

More specifically, amblyopia (lazy eye) is the main cause of preventable vision loss in children.

Studies suggest that a child cannot fully understand, and therefore cannot effectively undertake, a visual acuity test until they are 5 or 6 years old. However, if a child waits until this age, or later, then amblyopia and other vision impairments are significantly harder to treat and related learning difficulties can develop.

Regular vision screening assessments in early childhood reduce this risk by more than 50%. However, inefficiencies in current testing methods limit a child's access to accurate screening and subsequent treatment.

Traditional letter and picture charts are the current gold standard of visual acuity testing in children. However, these charts are subjective, require a response from the participant, and are therefore unreliable, inefficient and inaccurate.

In comparison, current vision screening methods such as portable autorefractors and photo screeners are objective. Nevertheless, these only measure risk factors of children’s vision and not visual acuity making them less effective.


Optokinetic Nystagmus

Optokinetic nystagmus (OKN) is an involuntary reflex of the eyes that occurs when an individual sees a moving object or pattern. It is well-recognized as a method of assessing visual acuity, but has, to-date, always been a highly subjective process for the detection of gross visual problems. Optokinetic nystagmus is the basis of our new approach to measuring visual acuity.

The Objective Acuity Vision Screening Test

  • Children look at a screen from 1.5 metres with one eye covered - each eye is tested separately.
  • The test displays a proprietary moving pattern to induce Optokinetic Nystagmus (OKN).
  • OKN is an indicator of an intact visual pathway.
  • When the eye detects a moving pattern, it generates OKN.
  • Eye tracking system captures the eye movement data which is analysed using OAL's proprietary algorithms.
  • If OKN is present then the child passes the test. If OKN is not present, then the child fails and requires further testing by an eye specialist.
  • The results show levels of accuracy that correlate with gold standard, age specific, vision screening levels in the US.


Proof of Concept Studies

Objective Acuity has completed several multinational clinical studies in Adults and Children with a prototype system. These clearly demonstrate proof of concept that the Objective Acuity Vision Screening Test reliably measures visual acuity in a vision screening application. The studies in children's demonstrated a high level of agreement between the Objective Acuity children's test currently considered the global clinical trials gold standard electronic (HOTV) and Lea Symbols visual acuity tests.

Tablet Based Studies

The recent studies on a tablet have also demonstrated a very high level of agreement with gold standard electronic (HOTV) and Lea Symbols visual acuity tests, while identifying those children that have vision problems with high sensitivity.

Future Studies

A study of 200 children in the USA with the commercial real-time tablet version of our vision screening test is planned to be initiated in March this year.


Intellectual Property

Objective Acuity is prosecuting a number of families of patents globally covering the Objective Acuity Vision Screening Test.
