Computerised static visual field testing using dedicated machines such as the Humphrey Field Analyzer (HFA) can assess and track changes in visual field sensitivity. The use of retrospective visual field databases is a novel undertaking, with no studies published utilising large scale population-level data. This study phase developed a method to extract HFA data into a large standardised population-based database including point sensitivity data with additional derived variables.
Retrospective, longitudinal, population study of visual field data from people who attended an ophthalmology service and had a HFA field test, in Western Australia, between 1988 and 2022. Raw test data included patient demographic fields, sensitivity readings and test parameters. Calculated fields included reliability scores, and a novel combined reliability score.
There were 606 230 tests for 92 215 study individuals, from 22 ophthalmology practices in metropolitan Perth and three public hospital eye clinics, representing around 85% of the field tests performed by ophthalmologists each year. Raw sensitivity values were available for all tests, and additional descriptors were available for most tests (97.5%-100% of tests) with the exception of data variables retired by the manufacturer.
Visual field data from 606 230 tests were collated into a single dataset, which is highly representative over a long period of time, for a defined population. This dataset has been linked to other administrative datasets to allow for epidemiological investigation of field of vision disorders.
使用专用机器（如 Humphrey 视野分析仪 (HFA)）进行计算机化静态视野测试，可以评估和跟踪视野敏感度的变化。利用回顾性视野数据库是一项新颖的尝试，目前还没有发表过利用大规模人群数据的研究。本研究阶段开发了一种方法，可将 HFA 数据提取到一个大型标准化人群基础数据库中，其中包括点敏感性数据和其他衍生变量。
这是一项在澳大利亚西部进行的回顾性、纵向、人群视野数据研究，研究对象为 1988 年至 2022 年间在眼科服务机构接受 HFA 视野检查的人群。原始测试数据包括患者人口统计学字段、敏感性读数和测试参数。计算字段包括可靠性评分和一种新的综合可靠性评分。
在 22 家位于珀斯大都市区的眼科诊所和 3 家公立医院眼科诊所中，有 92215 名研究个体进行了 606230 次测试，这代表了每年由眼科医生进行的视野测试的 85%左右。所有测试都提供了原始敏感性值，并且大多数测试（97.5%-100%的测试）都提供了其他描述符，除了制造商退役的数据变量。
将 606230 次测试的视野数据汇总到一个单一的数据集，该数据集在很长一段时间内对特定人群具有高度代表性。该数据集已与其他管理数据集相关联，以允许对视野障碍进行流行病学研究。
