Portable acuity screening for any school: validation of patched HOTV with amblyopic patients and Bangerter normals

Tsao Wu M, Armitage MD, Trujillo C, Trujillo A, Arnold LE, Tsao Wu L, Arnold RW. Portable acuity screening for any school: validation of patched HOTV with amblyopic patients and Bangerter normals. BMC Ophthalmol. 2017 Dec 4;17(1):232. doi: 10.1186/s12886-017-0624-y. PMID: 29202721; PMCID: PMC5716052.

Background: There was a need to validate and calibrate portable acuity screening tools so amblyopia could be detected quickly and effectively at school entry.

Methods: Spiral-bound flip cards and download pdf surround HOTV acuity test box with critical lines were combined with a matching card. Amblyopic patients performed critical line, then threshold acuity which was then compared to patched E-ETDRS acuity. 5 normal subjects wore Bangerter foil goggles to simulate blur for comparative validation.

PRODUCT PROFILE

Adapting the state-of-the-art principles for acuity testing, ABCD suggested a modification of Wendy Marsh-Tootle’s Surround HOTV 10-foot test card. The ABCD HOTV card presents 4 optotypes down to 20/16 range whereas Dr. Tootle’s stopped at 20/20. The matching card has surrounded letters to avoid confusion, has a “spectacle-delineated” pinhole enhancement and an HOTV near card that resembles Paul Runge’s near system but is adapted to just 10-inches found to be more approximate a child’s lap-reading distance. The 10-foot distance and 10-inch near are quickly demarcated by detachable strings. Age-appropriate screening cut-offs (20/40 for K and below, 20/32 for older than K) are quickly located by offset tabs. This chart has been used with objective screening in the Anchorage School District extensively.

ASK PV

Q:  What is Normal Vision?
A:  “Normal” visual acuity for healthy eyes is one or two lines better than 20/20. In population samples the average acuity does not drop to the 20/20 level until age 60 or 70. Always remember that the 20/20 reference standard does not refer to the average acuity of American eyes, just as the US standard foot is defined independently of the “normal” length of American feet.
