术语“明适应”的详细信息

英译术语:

photopic adaptation

汉语语境:

在使用人工瞳孔的实验中，几千次观察中的波动性消失的数量是可以忽略的。 这表明自然瞳孔大小的变化是负面感觉平衡感觉的波动的原因。低强度的刺激可以通过明适应性消失在阈值以下，但是超侧平衡感觉不永久地适应中性灰色。

英语语境:

In an experiment with an artificial pupil, the number of fluctuative disappearances in several thousand observations was negligible. This suggests that variations in the size of the natural pupil are responsible for fluctuations of sensations of supraliminal sensory equilibrium.Stimuli of low intensity may disappear below the threshold by photopic adaptation, but supraliminal equilibrium sensations do not adapt out permanently to neutral grey.

英译术语:

light adaptation

汉语语境:

光诱导广西巴马小型猪视网膜变性模型的建立与鉴定与光照前相比，持续间断光照2-4月龄小型猪3-6月后，视网膜OCT检查可见光变性猪视网膜全层(内界膜InnerLimitingMembrane至RPE层)厚度显著变薄；fERG检测发现光变性猪在暗适应最大混合反应的a、b波振幅和ops波振幅显著下降，明适应反应的b波及p1波振幅也有显著下降；mfERG检测发现光变性猪视条纹区P1波平均振幅密度显著降低。这都提示视网膜结构和功能发生了明显改变。视网膜OCT显示的外核层(Outernuclearlayer，ONL)厚度与离体视网膜石蜡切片HE染色显示的外核层厚度均明显变薄，说明了视网膜感光细胞发生了损伤，活体OCT结果与离体组织检测结果一致；视网膜透射电镜发现感光细胞内节线粒体肿胀、嵴断裂、空泡样变，外节膜盘结构破坏，视网膜色素上皮细胞微绒毛结构破坏，进一步表明视网膜感光细胞发生了损伤。

英语语境:

Post-light exposure, OCT examination showed the thickness of retinal ILM-RPE layer and ONL layer became significantly thinner; amplitudes of dark-adapted combined rod-cone response's a waves、b waves, OPS waves and b waves of light adaptation, p1 waves of the fERG significantly decreased; average amplitude density of p1 waves of the mfERG significantly lower; outer nuclear layer was significantly thinner in retinal HE staining. Transmission electron microscope showed the mitochondria of retinal photoreceptor cells after light exposure were swelling, the cristae were disrupted, the vacuolar were degenerated and the structure of retinal pigment epithelial cell microvilli was damaged.

英译术语:

bright adaptation

汉语语境:

对照组12例（14眼）和AMD患者组16人（18眼）均行矫正视力、裂隙灯、ERG及眼底检查，AMD患者同时行眼视网膜血管造影（FFA）、眼脉络膜血管造影（ICG）及光学相干断层扫描(OCT)检查，并根据OCT结果将AMD患者分3组，分别记录AMD患者与正常组及AMD患者组内暗适应和明适应3.0时a、b波的振幅及潜时，用SPSS17.00软件分析各组参数间的差异性。AMD组与对照组比较暗适应3.0时a波振幅P值为0.002,潜时P值为0.084，b波振幅P值为0.000,潜时P值为0.054；明适应3.0时a波振幅P值为0.000,潜时P值为0.000，b波振幅P值为0.000,潜时P值为0.059。AMD患者根据OCT结果分组比较：暗适应3.0时a波振幅P值为0.555,潜时P值为0.432，b波振幅P值为0.291,潜时P值为0.385；明适应3.0时a波振幅P值为0.236,潜时P值为0.001，b波振幅P值为0.045,潜时P值为0.138。与正常人相比湿性AMD患者a、b波振幅明显降低，这与视锥、视杆系统损伤相关。明适应ERG是在湿性AMD病变中反应较敏感，但能否将ERG作为湿性AMD病变分级的指标需进一步研究。

英语语境:

18 eyes of 16 cases with wet AMD( AMD group) and 14 normal control eyes of 12 people(control group) received examinations of corrected visual acuity，slit lamp microscope，ERG and fundus examination .The AMD group also underwent fundus fluorescein angiography(FFA), indocyanine green angiography (ICGA) and Optical Coherence Tomography(OCT). Assessing the integrity of inner /outer segment photoreceptor (IS/OS) and macular edema, classified into 3 groups using OCT. Recorded the ERG parameters of all subjects. The latency and amplitude of a/b waves at dark-adapted 3.0 and light-adapted 3.0 were analyzed by Spss17.0. The amplitude of a/b waves were lower and had a significant differences at dark-adapted 3.0 between the AMD and control groups: (Pa=0.002, Pb =0.000), which the same results appeared at light-adapted 3.0(Pa =0.000, Pb =0.000). However, the latency of a/b wives didn't exhibit so big differences except the light-adapted a (Pa=0.000). The others were Pa=0.084, Pb =0.054 at dark-adapted 3.0 and Pb=0.059 at light-adapted 3.0. Comparing the ERG parameters among the three groups of AMD, only at light-adapted 3.0, that the latency of a wave and the amplitude of b had significant correlation (Pa=0.001，Pb=0.045). There was no significant correlation between other ERG parameters: as the amplitude ofdark-adapted a/b (Pa =0.555, Pb =0.291) and light-adapted a (Pa =0.236), or the latency of dark-adapted a/b (Pa =0.432, Pb =0.385) and light-adapted b (Pb =0.138).The amplitude of a/b wives were significantly lower in wet AMD patients compared with the control group，which suggested the retinal function was seriously damaged. The bright adaptation of ERG is more sensitive in wet AMD, whether it can be used as a classification need to be further studied.
