Exploring standard and low luminance visual acuity and the Moorfields Acuity Chart as outcome measures in inherited retinal disease.

ABSTRACT:

Introduction

Standard visual acuity (VA) is often insensitive to subtle changes in vision that result from inherited retinal disease. Low luminance VA (LLVA) has grown in popularity as an alternative acuity measure. A new test, the Moorfields Acuity Chart (MAC) has been designed as a more sensitive and repeatable test for use in patients with age-related macular degeneration. The study explores the utility and repeatability of standard VA, LLVA and the MAC in a mixed cohort of patients with inherited retinal disease.

Methods

Participants were recruited as part of the visual function in retinal degeneration study (Ethics Reference 20/WM/0283). Standard VA was obtained using the Early Treatment of Diabetic Retinopathy study (ETDRS) chart placed at 4 m. LLVA was obtained using
