A cross sectional, prevalence survey of eye disease in the population over 75 years old of Melton Mowbray has been used to examine the accuracy and completeness of the Blind and Partially Sighted Registers. The Blind Register had high sensitivity and specificity but was found to underestimate the prevalence of blindness by a factor of 1.1. The Partially Sighted Register had high specificity, but the sensitivity was only 50% and it underestimated the prevalence of partial sight by a factor of 1.5. Seven persons eligible for registration, but previously not registered, were found, two as blind and five as partially sighted. This represented 21% of the registrable visually impaired population.
一项针对梅尔顿莫布雷75岁以上人群眼部疾病的横断面患病率调查,被用于检验盲人和视力部分受损登记册的准确性和完整性。盲人登记册具有较高的敏感性和特异性,但发现其将失明患病率低估了1.1倍。视力部分受损登记册具有较高的特异性,但敏感性仅为50%,且将视力部分受损患病率低估了1.5倍。发现有7名符合登记条件但此前未登记的人,其中2人被登记为盲人,5人被登记为视力部分受损。这占可登记视力受损人群的21%。
