• Research summary

  The purpose of the study is to validate the use of Electronic Visual Acuity against ETDRS charts (standard eye charts) in both control participants in patients with visual field loss affecting the area over the chart, i.e. patients with Rod-cone Dystrophy. There will be two arms to the study. In the first arm, 50 control participants will be recruited from members of the general public. In the second arm, 50 patient participants will be recruited from patients with an established diagnosis of RCDs attending the retinal clinics in Oxford Eye Hospital.\nAll participants will be asked to undergo visual acuity testing with both traditional ETDRS charts and with an EVA testing system produced by the EMMES Corporation, a healthcare research organisation. Bland-Altman analysis will be used to compare the test types.
