本研究的目的是比较Tuebingen手动视野计（TMP）和扫描激光检眼镜（SLO）对黄斑暗点（37只眼）的注视结果，并探讨注视行为对阅读能力的意义。进行动态TMP，特别注意中心暗点和盲点的位置。采用改良的SLO法对单个目标、不同长度和大小的单词以及文本进行视网膜注视点（RFL）测定。记录阅读过程中的眼动和RFL，发现在TMP中，78%的眼出现偏心注视，93%的眼出现暗点偏向上方和右上方视野。在SLO中，86%的眼睛观察到偏心注视，其中96%的眼睛的首选RFL位于上部和左上部视网膜。3只不完全绝对中心暗点眼的RFL依赖于刺激的大小，偏心注视是一种有效的适应机制。
The aim of this study was to compare fixation results assessed by Tuebingen manual perimetry (TMP) and scanning laser ophthalmoscope (SLO) and to examine the significance of fixation behavior for the reading ability in macular scotoma (37 eyes). Kinetic TMP was performed with special attention to the location of the central scotoma and the blind spot. Retinal fixation locus (RFL) was determined for single targets, words of different length and size as well as text using a modified SLO. Eye movements and RFL during reading were recorded simultaneously on videotape.In TMP, eccentric fixation was found in 78% of eyes, 93% of them showed a preferred direction of scotoma shift to the upper and upper-right visual field. With the SLO, eccentric fixation was observed in 86% of eyes, 96% of them had the preferred RFL in the the upper and upper-left retina. In three eyes with incomplete absolute central scotoma the RFL depended on stimulus size.Eccentric fixation is an effective adaptive mechanism for regaining rea...
