PHILADELPHIA — A pocket-sized ETDRS chart has the advantage of the high reproducibility of the standard ETDRS chart without the bulkiness, a speaker said here. While the Snellen chart is the ...

Visual acuity measured with the Dyop test varies significantly from ETDRS results under mesopic and blur conditions, ...

The Bailey–Lovie logMAR visual acuity chart, 1 along with the version produced by Ferris et al 2 (known as the ‘ETDRS’ chart), have become the gold standard tool for the measurement of ...

ETDRS charts use equal spacing between letters and lines, making the acuity chart more balanced.14 This chart format has been accepted by the National Eye Institute and the FDA, ...

To evaluate the relationship between visual acuity as measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) chart and by the potential acuity meter (PAM) with retinal thickness and ...

They ask a person to read letters from an eye chart known as an ETDRS chart. This chart has several rows of 5 letters, decreasing in size and, therefore, difficulty.

The patients’ LogMAR (Logarithm of the Minimal Angle of Resolution) scores, which are derived from the number of letters patients read on the ETDRS chart, were used for statistical purposes.

Notably, treated eyes achieved a statistically significant two-line gain (10 letters) in low-luminance visual acuity (LLVA) on the ETDRS chart, regardless of genetic mutation, with a p-value of 0.01.

Durable improvement in best-corrected visual acuity (BCVA), as GS010-treated eyes sustain +15.4 ETDRS letters equivalent improvement versus baseline and +28.1 ETDRS letters equivalent versus nadir ...

The Phase 3 STAR study did not meet primary or key secondary endpointsChoroideremia is a rare inherited retinal disease that results in progressive vision loss, ultimately leading to blindness ...

The smartphone application follows the standard ETDRS chart design, with a letter E displayed in one of four orientations (90°, 180°, 270°, and 0°).
