查询词典 visual acuity

Methods: Under the condition of photopia or eopsia, the dynamic visual acuity of 31 pilots were measured by LDS-1 dynamic vision tester when breathing the air(the oxygen density was 20%) and low oxygen (the oxygen density was 14.5%-15.2%).

目的：考察急性轻度缺氧对飞行员视觉追踪辨认能力的影响。

It may present with disturbance of visual acuity, and progressive proptosis.

它能影响视力及造成渐进性的眼球外凸。

Best-corrected visual acuity was 20/40 or better in 25 of 61 study eyes (41%). Primary retinal reattachment was attained in 60 study eyes (98%).

最佳矫正视敏度是20/40或者61例中25例(41%)较好。60例(98%)获得一期视网膜复位。

The visual acuity of 25 cases was increased and 11 eyes (91.7%) retina reattachment after follow-up period for 3 to 10 months.

术后随访观察3~10个月，31只眼中25只眼视力不同程度提高，11(91.7%)眼视网膜复位。

Main outcome measures were done on final visual acuity, early complications and refractional deviation.

主要记录患者最佳矫正视力，早期并发症及屈光偏差。

The visual acuity and light sensitivity were altered by TTT in the eyes with absolute scotoma.

所有被检出有绝对暗点的患眼治疗后视力均无明显变化，视网膜的光敏度不变。

Results Absolute scotoma appeared in 7 eyes and relative scotoma in 6 eyes before TTT. Among the 6 eyes with relative scotoma, the visual acuity was improved over 2 lines in 4 eyes after TTT, descended 1 line in I eye and unchanged in 1 eye. The light sensitivity of the irradiated retina was increased in 5 eyes and decreased in 1 eye.

治疗后与治疗前相比较，6眼TTT前检出相对暗点的患眼中，治疗后视力提高者4眼，1眼视力下降，1眼视力无明显变化；6眼中5眼TTT治疗后激光照射处视网膜的光敏度提高，1眼降低。

The dynamic visual acuity of 10 subjects remained 20/20 (50%), while that of the other 10 subjects dropped only by less than 2 lines on the vision screener.

结果：在实验一的20位志愿者其静态视力均为20/20，而在动态环境下有一半的受测者维持不变，另外一半的动态视力也仅下降一、两行而已（即20/25或20/30）。

Methods LASEK was performed on 40 eyes of 22 patients with extremely high myopia. Mean preoperative uncorrected visual acuity was 0.02±0.02(range 0.01-0.05) and the mean spherical equivalent was -12.75±2.30 D.

应用德国Zeiss MEL 80准分子激光器对－10.00以上的超高度近视22例（40眼）施行LASEK术，术前平均裸眼视力0.02±0.02 (0.01~0.05)，平均等效球镜(-12.75±2.30)D。

The best corrected visual acuity was hand motions vision. Biomicroscopy revealed a small posterior subcapsular cataract in both eyes. On funduscopy, both eyes showed waxy pale appearance to the optic nerve head, vessel attenuation, diffuse bone spicule pigmentation in the retina beyond the superior and inferior vascular arcades.

裂隙灯下见双眼晶体后极部后囊膜下皮质轻度混浊，直接检眼镜下可视盘蜡黄色，边界清楚，视网膜血管变细，视网膜色污秽，上下血管弓以外视网膜可见大量骨细胞样色素沉着，左眼后极部黄斑区呈金箔样反光。D-15色彩排列试验不能查。
