“…The data of Peters (1968), Malmquist (1965) and Robbins and Bailey (1975) are consistent with and explain why, current school vision screening programmes given by health departments in Australia detect only one-half of the defects that can be predicted and found by epidemiological studies.…”

“…Current screening techniques assume as a modus operandi that distance visual acuity is a valid index of total visual integrity. Peters (1968), Dean of the School of Optometry and Professor of Public Health in the Medical Centre, University of Alabama, showed this premise is invalid. He compared the visual performance attainable when visual defects considered clinically significant by optometrists and ophthalmologists are present with the visual performance necessary to reach acceptable levels of visual acuity on a Snellen chart.…”

“…Participants covered the eye not being tested. The best score for visual acuity was recorded for each eye using metric notation from the Snellen chart, where the numerator was ‘6 metres’ [15]. The denominators were based on the Snellen metric notation.…”

Association between alcohol consumption and diabetic retinopathy and visual acuity-the AdRem Study Lee, C. C.; Stolk, R. P.; Adler, A.

AbstractAims We investigated the association between alcohol consumption and diabetic retinopathy and deterioration of visual acuity in individuals with Type 2 diabetes.Methods We conducted a cohort analysis of 1239 participants with Type 2 diabetes aged 55-81 years enrolled in the AdRem study, a sub-study of the Action in Diabetes and Vascular Disease: Preterax and Diamicron MR Controlled Evaluation (ADVANCE) trial. Current and past consumption of wine, spirits and beer was measured by self-report. Moderate and heavy alcohol consumption was defined as 1-14 and > 14 drinks ⁄ week, respectively. Diabetic retinopathy, measured by mydriatic stereoscopic seven-field retinal photography, was defined by a 2-step progression in the Early Treatment of Diabetic Retinopathy Study (ETDRS) score or the presence of any retinal vascular lesions. Deterioration of visual acuity was defined by a decrease of two lines in best vision in either eye, measured corrected, or through a pinhole using a Snellen chart.Results In a mean follow-up of 5.5 years, we identified 182 participants with a 2-step progression in the ETDRS score, 640 participants with the presence of any retinal vascular lesions and 693 participants with a deterioration of visual acuity. Current moderate consumption of alcohol, compared with no current consumption, was not associated with presence or progression of diabetic retinopathy; however, it was associated with higher risk of deterioration of visual acuity (multivariable-adjusted OR 1.83; 95% CI 1.34-2.48; P < 0.001).Conclusions Alcohol consumption is associated with increased risk of deterioration of visual acuity, but not with retinopathy in individuals with Type 2 diabetes.

“…Visual acuity testing alone would have identified 55% of the defects including colour vision and visual acuity test plus cover test would identify only 68% of the total defects excluding colour vision. Peters (1961) in discussing vision screening with a Snellen chart i.e. visual acuity testing alone, states ' I .…”

Our education systems place heavy reliance on visually presented material and consequently, children with vision defects need to be identified and treated when necessary. All school children should be given vision screening examinations. The scope of various vision screening methods and their relative merits are examined. The Victorian College of Optometry has been operating a school vision screening programme for some years and the clinical content of the screening examination together with the practical aspects of setting up and administering the programme are discussed. An analysis of the results of 1400 screening examinations, including some re‐tests, is presented and compared with other data relating to the vision of school age children and, in view of these findings, recommendations are made about the need for universal and regular vision screening examinations for school children.
