Summary

This study aims to compare a home vision self-assessment test to office-based Snellen visual acuity in myopic children.

Detailed description

Visual impairment is an important public health issue worldwide, with a heavy socioeconomic burden. More than 400 million people globally have mild to severe visual impairment. Visual acuity (VA) screening is the most basic part of ophthalmic examination. Home vision screening tests have become an important way to obtain a measure of an individual's VA without an office-based clinic visit. Knowing a patient's VA can help ophthalmologists remotely triage acute calls, monitor visual recovery after medical or surgical interventions, and ensure visual stability in follow-up telemedicine visits. Home vision screening tests have become an important way to obtain a measure of an individual's VA without an office-based clinic visit. Numerous electronic home vision assessment tools exist, but many of these are used through applications on mobile or tablet devices.

Conditions

• Home Vision
• Office-Based Snellen Visual Acuity
• Myopic Children

Interventions

Type	Name	Description
OTHER	Snellen chart	Patients will be asked to use the 5 feet distance for standardization, which allows for visual acuity assessment from 20/16 to 20/200. Patients will be asked to wear their current corrective lens for distance, to take the test at home in a place with good lighting and to test each eye separately. Office-based vision testing will be performed by a trained ophthalmic technician in a dimmed room with the Snellen chart illuminated on a screen. Patients will be asked to wear their current corrective lens for distance and an eye occluder will be used to test each eye separately.
