PURPOSE
To present a method of visual field examination using a video projector. Also, we compare our results with those of a Humphrey perimeter, which is accepted as standard in automated perimetry.
MATERIALS AND METHODS
Software implementing a full-threshold 4-2-step staircase algorithm for the central 30-2 of the visual field (76 points) has been developed and tested in nine eyes of seven patients using an Epson TW 700 video projector. The results were compared to those obtained from the same patients using the Humphrey perimeter.
RESULTS
High correlation between the video projector visual fields and those of the Humphrey perimeter was found. The point-to-point correlation coefficient ranged from 0.75 to 0.90, with P<0.0001 for each eye.
CONCLUSION
Visual field examination results using a video projector have high correlation with those of a Humphrey perimeter. The method is possibly suitable for clinical use.
目的
介绍一种使用视频投影仪进行视野检查的方法。此外，我们将我们的结果与 Humphrey 视野计的结果进行比较，Humphrey 视野计在自动视野检查中被视为标准设备。
材料与方法
已开发出一种软件，该软件在视野中央 30°（76 个点）实施全阈值 4-2 步阶梯算法，并使用爱普生 TW 700 视频投影仪在 7 名患者的 9 只眼中进行了测试。将结果与使用 Humphrey 视野计从相同患者获得的结果进行比较。
结果
发现视频投影仪视野与 Humphrey 视野计的视野之间具有高度相关性。点对点相关系数范围为 0.75 至 0.90，每只眼的 P<0.0001。
结论
使用视频投影仪的视野检查结果与 Humphrey 视野计的结果具有高度相关性。该方法可能适用于临床应用。
