Efficacy of PEEK Acuity Versus ETDRS Chart for Assessment of Visual Acuity and Refractive Error

NCT06913491 | Active Not Recruiting DMC

Brief Summary

Visual acuity is a key indicator of visual function, often measured using the ETDRS chart, the gold standard in clinical settings. However, the increasing need for accessible and cost-effective screening tools, especially in underserved areas, has led to the development of mobile health applications like the Peek Acuity application.

Outcome Measures

Primary Outcomes (1)

• Peek Acuity

  Peek Acuity is easier to administer than an equivalent wall chart, such as Snellen or ETDRS, and is generally quicker to complete. The algorithm that controls progress through each test is optimised for clinical accuracy, so the test will end just as soon as a reliable score has been obtained.
