Here we summarise three research papers from a recent issue of Optometry in Practice.
The journey of visual acuity: are we nearly there yet?
Roger S Anderson FCOptom, Steven C Dakin and Nilpa Shah MCOptom
Visual acuity measurement continues to be a fundamental component of every eye examination. This paper reviews the development of acuity tests, from those used more than 1000 years ago to the Moorfields Acuity Chart of 2015 and the current “gold standard”.
The authors identify the reasons for various remaining deficiencies and present recent, novel chart designs intended to address these weaknesses and achieve the ultimate goal of developing tests that are accurate, precise, sensitive and specific.
One thing is certain: I wasn’t expecting the events of the last 10 weeks to take place when I wrote my last Optometry in Practice editorial in February this year.
