简要总结
This study aims to compare a home vision self-assessment test to office-based Snellen visual acuity in myopic children.
详细描述
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.
