Eye Chart Pro 3.1.0

Eye Chart Pro: A Widely Used Medical Application with Over 500,000 Downloads

Eye Chart Pro is a clinically validated, randomized visual acuity testing tool designed for remote use. It offers an intuitive and patient-friendly experience for both clinicians and patients, and it is available at no cost. Unlike traditional chart projectors, which often exceed $1,000 in price, this application provides comparable functionality in a portable format. Refer to the final screenshot for details on clinical validations published in peer-reviewed journals and their key findings.

Potential applications include:

• Initial triage assessments
• Support during house visits
• Assessments for patients who have memorized standard office charts

Key features encompass:

• Randomizable Snellen chart
• Randomizable Tumbling E chart
• Option to randomize either the entire chart or individual lines
• Smooth interface enhanced with animations
• Basic remote control functionality
• Support for metric and imperial (feet) units

Description:

Eye Chart Pro serves as a versatile tool generating randomized Snellen and Tumbling E charts to facilitate quick, approximate assessments of visual acuity. Users can easily randomize the full chart or just specific lines by tapping. Switching between Snellen and Tumbling E modes is straightforward via a dedicated toggle button.

While Snellen charts remain a staple in eye examinations worldwide, memorization can compromise measurement accuracy. Eye Chart Pro offers a portable alternative suitable for situations where traditional charts are unavailable or as an adjunct to static wall charts. Though intended for screening purposes and not replacing comprehensive optometric evaluation, it provides a convenient means of obtaining a preliminary visual acuity estimate.

The development team is committed to ongoing improvements and values user feedback. Please review the summarized clinical validations below:

• ETDRS Chart on Eye Chart Pro on iPad: “Validation of the visual acuity iPad app Eye Chart Pro compared to the standard Early Treatment Diabetic Retinopathy Study chart in a low-vision population,” Journal of Telemedicine and Telecare. The study concludes: “The ETDRS chart function on the Eye Chart Pro application can reliably measure VA across a range, from normally sighted patients to those with low vision.”
• Sloan Chart on Eye Chart Pro on iPad: “The validity of visual acuity assessment using mobile technology devices in the primary care setting,” Australian Family Physician. The authors state: “The high level of agreement of visual acuity results between the Snellen wall chart and both mobile technology devices suggests that clinicians can use this technology with confidence in the primary care setting.”
• Tumbling E Chart on Eye Chart Pro on iPad: “A Pilot Trial of the iPad Tablet Computer as a Portable Device for Visual Acuity Testing,” Journal of Telemedicine and Telecare. Findings indicate: “Bland-Altman analysis revealed a mean difference (bias) of 0.02 logMAR units between the VA results from the iPad chart and the light-box chart, with 95% limits of agreement from -0.14 to 0.19.”
