正常瞳孔大小受视网膜照度、光刺激的远近以及情绪的影响。在充分暗适应状态下,瞳孔直径可达8mm,在明适应状态下,瞳孔直径可缩小至2mm。正常情况下,老年人瞳孔相对较小。通常文献报道女性瞳孔大于男性,近视眼瞳孔大于正视眼,然而这些报道并未得到客观方法研究结果的证实。为了排除调节、辐辏以及瞳孔对光反射等因素的影响,作者采用客观的动态红外线瞳孔测量法,对48例受试者进行了测量。在半暗背景下,男、女性正视眼瞳孔大小分别为6.00±0.24和5.60±0.22mm;男、女性单纯近
Normal pupil size is affected by retinal illumination, the extent of light stimulation, and mood. Under full dark adaptation state, the pupil diameter up to 8mm, under the state of adaptation, the pupil diameter can be reduced to 2mm. Under normal circumstances, the elderly pupil is relatively small. It is generally reported in the literature that female pupils are larger than men and myopia pupils are larger than those of the frontal eyes. However, these reports have not been confirmed by objective methodological studies. In order to rule out the effects of regulation, convergence and pupil on light reflex, the authors measured 48 subjects using objective dynamic infrared pupilometry. In the dark background, male and female pupil pupil size were 6.00 ± 0.24 and 5.60 ± 0.22mm; male and female simple near
