To determine the feasibility of using a computer game to measure visual fields in children.
The authors describe the development and assessment of a novel computer-game apparatus to measure visual fields in children. It is based upon a computer game visible on a monitor, housed in an interactive model-castle structure.
The authors conducted a total of 25 field tests with the final apparatus, in 25 eyes of 19 children, aged 4-14 years. On two occasions children failed to complete the exam, owing to hardware and software defects that were subsequently rectified. For the 23 completed fields, the median time for completion of the full test was 4.5 min. 16 out of 18 clinically normal patients showed normal fields; the only failures were in two 4-year-old children who still managed to complete fields, but with generalised reduced responses that were deemed abnormal by our predetermined criteria. For the five eyes with expected glaucomatous loss, all five visual fields measured were completed and showed abnormal fields consistent with their medical condition. Positive feedback was given from all children about their testing experience.
It is feasible to develop a computer-game-based system to measure fields in children in a non-invasive, affordable and entertaining way.
确定使用电脑游戏测量儿童视野的可行性。
作者描述了一种新的电脑游戏设备的开发和评估，用于测量儿童的视野。它基于一个在显示器上可见的电脑游戏，位于一个互动模型城堡结构中。
作者共对 19 名 4-14 岁儿童的 25 只眼睛进行了 25 次现场测试。由于硬件和软件缺陷，有两次儿童未能完成检查，随后进行了纠正。对于 23 个完成的视野，完成全测试的中位数时间为 4.5 分钟。18 名临床正常患者中有 16 名显示正常视野；唯一的失败是在两名 4 岁的儿童中，他们仍然设法完成了视野，但由于我们预定的标准认为普遍的反应减少是异常的。对于预计有青光眼损失的五只眼睛，所有五只测量的视野都已完成，并且显示出与他们的医疗状况一致的异常视野。所有儿童都对他们的测试体验给予了积极的反馈。
以一种非侵入性、负担得起和有趣的方式，开发一种基于电脑游戏的系统来测量儿童的视野是可行的。
