Comparing a Home Vision Self-Assessment Test to Office-Based Snellen Visual Acuity in Myopic Children

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

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.

Inclusion Criteria:

• Age ≤ 18 years.
• Both sexes.
• Patients who completed the home visual acuity test and have a subsequent office-based visual acuity test.

Exclusion Criteria:

• Last in-office visual acuity of 20/125 or worse in both eyes (to allow for a buffer of at least 2 lines of vision from the upper limit of 20/200 on the home vision assessment).
• Lack of access to MyChart.
• History of keratopathy, cataract, glaucoma, retinal detachment, neuro-ophthalmic disease, or other eye diseases.
• History of ophthalmic surgery or trauma.
• History of systemic diseases.
• Severe psychological or psychiatric diseases.
