Grids for Photopic, Mesopic and Scotopic Microperimetry in the MP3-S device

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.

本数据集包含我们为MP3-S微视野检查仪（由日本Nidek、Gamagori公司生产）执行顺序性视光、中光和暗适应实验所提出的网格。本处所使用的特定配置和网格命名为MGT020，并附以测试模式（MGT020 Photo、Meso或Scoto）。所有这些.xml文件均可直接通过NAVIS-EX软件中的图案编辑器导入设备。我们所采用的测试配置如下：为了本实验协议的需要，我们开发了两种定制网格：一种用于视光和中光测试的32点网格，另一种用于暗适应测试的28点网格。两种网格均测试黄斑中央10度（10-2）。在视光和中光测试中，使用了持续时间为200毫秒的Goldmann III型刺激，采用4-2策略，背景亮度分别为31.4 asb（9.99 cd/m²）的视光和4 asb（1.27 cd/m²）的中光。注视目标为一个1度大小的红色十字。在这些模式下，设备的动态范围为34 dB。在暗适应测试中，网格由28个点组成——与中光/视光测试中使用的相同32个点，但去除了距黄斑中心2度范围内的四个位置（无视杆区；如图1A所示，标记为点1、9、17和25）。使用了持续时间为200毫秒的Goldmann V型刺激，采用4-2策略，背景亮度为0.003 asb（0.0009 cd/m²）。在暗适应设置下，设备的动态范围为24 dB。
