视力

Methods: The vision of 679 pilots were examined by circular optical visual chart, and the horizontal and vertical heterophoria, by the STEVEN rotary pris in 6 meters distance, small pupils and fundus, by routine method.

Research background: Choroidal neovascularization is a common cause of vision loss in patients, which often resulted from exudative Age-related macular degeneration、 pathologic myopia、 central serous chorioretinopathy、ocular histoplasmosis and angioid streaks, Rarely, CNV is seen in children, usually in association with inherited macular dystrophies. Despite extensive basic and clinical research, our knowledge of the complicated molecular mechanism of CNV is still limited, for these reasons currently used therapeutic approaches are insufficiently effective.

课题研究背景：脉络膜新生血管(choroidal neovascularization，CNV)是导致视力丧失的一种常见原因，多继发于渗出型年龄相关性黄斑变性、近视性黄斑变性、中心性浆液性脉络膜视网膜炎、眼组织胞浆菌病和眼底血管样条纹等眼病，在儿童罕见，主要与遗传性黄斑营养不良有关，尽管近年来进行了大量的基础和临床研究，但对CNV复杂分子机制的认识仍然非常有限，因此目前的治疗措施都不尽如人意。

The focus depth of the photometer is quite large. Observer's minor visual defects, such as myopia and hypermetropia will not affect the observation results.

由於测量器的景深较大，观测者的近视或远视等轻微视力问题不会对测量结果做成影响。

Methods: Add different power spherical lenses on 32 volunteers with normal binocular function to induce simple myopia(+1D,+2D,+3D),simple hypermetropia(-1D,-2D,-3D) and anisometropia.Assess the visual acuity,stereocontrast sensitivity and Worth 4 dots fusional function after inducing the anisometropia.

对双眼视功能正常的大学生志愿者32人采用在单眼前加不同度数正负球镜的方法，诱导单纯近视性(+1D，+2D，+3D)及单纯远视性(-1D，-2D，-3D)屈光参差，测定诱导屈光参差后的视力、立体视敏度及Worth四点融像功能。

Results: Primary glaucoma invasive age from 60-70 was crest-time, it was 41.60% of sum; female patients were majority, it was 62.18% of sum; spring is high incidence time, it was 36.13% of sum; primary glaucoma was chronic disease, averaged course was two years-two months; usual symptom are hyperpyrexia of liver (34.03%), stagnation of QI due to depression of the liver (17.23%), hepatic and renal yin deficiency (13.45%), asthenic yin causing excessive pyrexia (11.76%), upward invading of wind-fire disturbing eye (11.76%), asthenic yin causing predominant yang (9.24%); inpairment of vision, eyes pain, shallow of anterior chamber were usual complaint and physical sign; using frequency usual prescription from hing to low were: hoelen, isapgol, anemarrhenae, glycyrrhiza uralensis, alisma rhizoma, cortex moutan, etc.

结果：原发性青光眼发病年龄以60~70岁最多见，占总例数41.60%；性别中女性患者居多，占62.18%；发病时间以春季最多，占总病例数36.13%；本病以慢性发病为主，病程平均为2年2个月；常见证候为肝火上炎证(34.03%)、肝郁气滞证(17.23%)、肝肾阴虚证(13.45%)、阴虚火旺证(11.76%)、风火上扰证(11.76%)、阴虚阳亢证(9.24%)；视力下降、旅胀痛、前房浅等较为常见的症状与体征；常用方使用频率由高到低依次为绿风羚羊饮、六味地黄汤、逍遥散等；常用药物使用频率由高到低依次为：茯苓、车前子、知母、甘草、泽泻、丹皮等。

Optic perineuritis in secondary syphilis may not affect vision. Early awareness of macular hypopyon and perineuritis from secondary syphilis allows rapid diagnosis and therapy.

早期发现与治疗可以帮助患者恢复视力并减少梅毒产生的其他后遗症，因此眼科医师在此扮演非常重要的角色。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
