资源简介:
These are the grids we propose for performing sequential photopic, mesopic and scotopic in the MP3-S microperimetry device (Nidek, Gamagori, Japan). The name of the specific configuration and grids we have used herein is MGT020 followed by the modality (MGT020 Photo, Meso or Scoto).All these .xml files can be imported directly to the device via the Pattern Editor in the NAVIS-EX software.The testing configurations we used are as follows:For the purposes of this protocol, we developed two custom grids: a 32-point grid to be used for photopic and mesopic, and another 28-point grid to be used in scotopic testing. Both grids test the central 10 degrees of the macula (10-2).In photopic and mesopic testing, a Goldmann size III stimulus with 200 ms duration was used in a 4-2 strategy, on a background luminance of 31.4 asb (9.99 cd/m²) for photopic, and 4 asb (1.27 cd/m²) for mesopic. The fixation target was a 1-degree size red cross. The dynamic range of the device in these modalities is 34 dB.In scotopic testing, the grid is composed of 28 points – the same 32 points used in mesopic/photopic testing minus the four positions within 2 degrees of the fovea (rod-free zone; marked as points 1, 9, 17 and 25 in Figure 1A). A Goldmann size V stimulus with 200 ms duration in a 4-2 strategy, and a background luminance of 0.003 asb (0.0009 cd/m²) was used. The dynamic range of the device in scotopic setting is 24 dB.
本研究提出的格栅适用于MP3-S型微视野计(Nidek,日本蒲郡)开展明视觉(photopic)、中间视觉(mesopic)与暗视觉(scotopic)顺序检测。本研究中使用的特定配置与格栅的命名格式为MGT020加上对应视觉模式后缀(即MGT020 Photo、MGT020 Meso或MGT020 Scoto)。所有上述XML格式文件均可通过NAVIS-EX软件中的图案编辑器直接导入该设备。
本研究采用的检测配置如下:
为符合本实验方案要求,我们定制了两款检测格栅:一款为32位点格栅,用于明视觉与中间视觉检测;另一款为28位点格栅,用于暗视觉检测。两款格栅均覆盖黄斑中心10°范围(10-2检测模式)。
在明视觉与中间视觉检测中,采用时长200ms的戈德曼(Goldmann)Ⅲ号视标,遵循4-2检测策略;明视觉检测的背景亮度为31.4 asb(9.99 cd/m²),中间视觉检测的背景亮度为4 asb(1.27 cd/m²)。固视目标为1°大小的红色十字。该设备在此两种检测模式下的动态范围为34 dB。
在暗视觉检测中,格栅包含28个检测位点:即移除明/中间视觉检测所用32位点中,位于中心凹2°范围内的4个位点(无视杆细胞区;对应图1A中的1、9、17及25号位点)后得到的格栅。暗视觉检测采用时长200ms的戈德曼(Goldmann)Ⅴ号视标,遵循4-2检测策略,背景亮度为0.003 asb(0.0009 cd/m²)。该设备在暗视觉检测模式下的动态范围为24 dB。
