Not only it impairs patients" genital health and Quality of life, but also is associated with an increased risk of type 2 diabetes, endometrial carcinoma, hyperlipemia, hyperpiesia, cardiovascular and cerebrovascular events. Up to now, precise pathogenesy of PCOS is yet unknown. The modern medicine indicates the etiopathogenisis of PCOS related to hereditism, endocrinology, immunology, metabolism and so on. The main features are hyperandrogenism and hyperinsulinemia, the correlation and between the above factors and how they inference PCOS are still unclear. In the view point of Traditional Chinese Medicine ,PCOS classifies to "menopathy","infertility" and "Zhengjia , its occurrence exists a close relationship with dysfunction of liver, kidney, spleen and further inducing deficiency, sputum, sluggish stagnant and fire. Many scholars insist that pathogenesis of PCOS is a renal deficiency plus phlegmatic hygrosis. However, after many years clinical observation.

随着研究的不断深入，PCOS日益显示出其复杂性和重要性；他不仅影响到患者的生殖健康及生存质量，而且其异常的激素环境使该类患者对子宫内膜癌、高血压、高血脂及心脑血管意外等病发生危险明显增加；但目前该病的确切发病机制尚不十分清楚，现代医学认为其病因涉及到遗传、内分泌、免疫、代谢等多个方面，以高雄激素血症与高胰岛素血症为主要特征，二者在PCOS发病中的确切作用，目前尚不清楚；PCOS相当于祖国医学的&月经病&&不孕&&癥瘕&等范畴，本病的发生与肝、肾、脾功能失调导致虚、痰、瘀、火有关。

In our CT examination, intravenous administration of contrast material is essential to determine the cause of obstruction and identify any associated hernial strangulation.

Methods A total of 264 patients with sensory strabismus were reviewed. The contents analyzed include the frequency of etiologic factors leading to visual impairment, the visual acuity of eye with sensory heterotropia, the relationship between age of onset of visual decrease and the type of strabismus, the prevalence of DVD.

回顾性总结分析诊治的264例知觉性斜视患者的临床资料，包括导致视觉损害的病因分布，患眼视力情况，视觉障碍年龄与斜视类型的关系，分离性垂直性斜视的检出率等。

The esotropia was encountered when the onset of visual impairment occurred at birth or less than 1 year old of age. Exotropia predominated in more than 1 year old children and adults. DVD may also occur in association with sensory heterotropia, we should take DVD into account when planning the surgical treatment of horizontal strabismus.

屈光参差、视网膜病变、视神经损害、先天性白内障、外伤性白内障是导致知觉性斜视的主要病因；其中小于1岁与大于1岁者相比，发生内斜视的比例较大，1岁以后主要发生外斜视；知觉性斜视者可伴有DVD的存在，在水平斜视的手术中要考虑此问题。
