全身疾病通过一定途径累及眼球,产生眼部病变,这些眼部病变的严重程度与全身疾病的进展密切相关。人工智能(artificial intelligence,AI)通过识别眼部病变,可以实现对全身疾病的评估,从而实现全身疾病早期诊断。检测巩膜黄染程度可评估黄疸;检测眼球后动脉血流动力学可评估肝硬化;检测视盘水肿,黄斑变性可评估慢性肾病(chronic kidney disease,CKD)进展;检测眼底血管损伤可评估糖尿病、高血压、动脉粥样硬化。临床医生可以通过眼部影像评估全身疾病的风险,其准确度依赖于临床医生的经验水平,而AI识别眼部病变评估全身疾病的准确度可与临床医生相媲美,在联合多种检测指标后,AI模型的特异性与敏感度均可得到显著提升,因此,充分利用AI可实现全身疾病的早诊早治。
Systemic diseases affect eyeballs through certain ways, resulting in eye diseases; The severity of eye diseases is closely related to the progress of systemic diseases. By identifying eye diseases, artificial intelligence (AI) can assess systemic diseases, so as to make early diagnosis of systemic diseases. For example, detection of the degree of icteric sclera can be used to assess jaundice. Detection of the hemodynamics of posterior eyeball can be used to evaluate cirrhosis. Detection of optic disc edema and macular degeneration can be used to evaluate the progress of chronic kidney disease (CKD). Detection of ocular fundus vascular injury can be used to assess diabetes, hypertension and atherosclerosis. Clinicians can estimate the risk of systemic diseases through eye images, and its accuracy depends on the experience level of clinicians, while the accuracy of AI in identifying eye diseases and evaluating systemic diseases can be comparable to clinicians. After combining various detection indexes, the specificity and sensitivity of AI model can be significantly improved, so early diagnosis and early treatment of systemic diseases can be realized by making full use of AI.

目的:探讨上睑提肌缩短术和额肌肌瓣悬吊术后眼表改变和恢复的差异。方法:对2007 年1 月至2007 年4 月在中山眼科中心住院的42例(62只眼)先天性上睑下垂患者,按手术方式和术后是否加用局部用药进行随机分组,观测各组术后2 d、5 d、7 d和2周患者泪液的分泌、泪膜破裂时间、结膜充血、角膜荧光染色、睑板腺功能、瞬目次数、上睑睫毛角度和眼睑闭合情况,并分析其观察结果的差异是否有统计学意义。结果:3名患者(7.1 %)因需要加用其它促角膜上皮生长的药物而退出本研究,其中1例(2.3 %)因倒睫刺激角膜上皮水肿缺损需行手术调整,其余所有患者眼表检测项目的结果均显示不同程度地受到了手术影响,但是随着术后炎症的逐渐消退,这些受影响的眼表异常均会逐渐恢复正常。泪膜破裂时间、瞬目次数、眼睑闭合情况的影响在两种术式之间的差异有统计学意义,而在术后是否局部用药之间没有统计学差异;角膜荧光素染色在是否加用局部用药组之间有统计学差异,而不同术式之间没有统计学差异;泪液分泌量、结膜充血、睑板腺功能、睫毛角度则在所有组别之间均没有统计学差异。结论:两种上睑下垂的矫正术均会引起患者眼表的改变,额肌肌瓣悬吊术对泪膜破裂时间、瞬目次数、眼睑闭合情况影响的程度较大,而局部用药只能改善角膜荧光素染色异常、对其它眼表因素影响不大。上睑睫毛角度异常是引起角膜损害最危险的因素。
Objective : To investigate the difference of ocular surface change and restoration after ex-ternal levator advancement and frontalis suspension.Methods : Forty-two patients (62 eyes) with congenital ptosis hospitalized in ZhongshanOphthalmic Center from Jaruary to April in 2007 were randomly divided into four groups according to different surgery types and with or without post surgery ophthalmic medica-tion. Sehirmer test, tear film break-up time , conjunctiva congestion , cornea fluorescentpigmentation , tarsal gland function , winking frequency, angle of eyelash and eyelid clo-sure were all observed and statistically analyzed in all groups 2 days , 5 days , 7 days and 2 weeks after surgery.Results : Except 3 patients needed advanced ophthalmic medicine, one of whom waswith corneal ulceration and needed another surgery, all the others were observed withocular surface items altered in varied degrees and gradually returned to normality as theinflammation caused by surgery recovered. Break-up time , winking frequency and eyelid closure were statistically diferent between the two types of surgery but not betweengroups with and without post surgery ophthalmic medication. Cornea fluorescent pigmen-tation was statistically different between groups with and without post surgery ophthalmicmedication but not between the two types of surgery. The other items did not have statis-tical difference in all groups.Conclusion : The two types of surgery for ptosis correction could alter the ocular surface ,but frontalis suspension affect tear film break-up time , winking frequency and eyelid clo-sure much more than levator advancement. Ophthalmic medication after the surgerycould only ameliorate cornea fluorescent pigmentation but was not necessarily to restora-tion of normal ocular surface. Abnormality of eyelash angle was the most dangerous fac-tor to the corea injury.

With the change of human lifestyle and overuse of eyes in recent years, the market demand for ophthalmic drugs continues to grow. However, the ocular therapy is still facing the shortage of doctors and drugs. Due to the risk of high cost, long lead time and low success rate, the process of novel ophthalmic drug innovation and iteration is getting slower. As an emerging technology, artificial intelligence is expected to enable the whole process of ophthalmic drug discovery and development, including drug target discovery, compound screening, pharmacokinetic model innovation and clinical trials, thus reducing R&D costs and increase efficiency for ophthalmic drug discovery and development. In addition, with the improvement of big data, hardware calculation and the deep integration of life science and intelligent science, the role of artificial intelligence in ophthalmic drug discovery and development will be significant improved , contributing to achieve the leap from precision to intelligence.
手术前常规检查在临床诊疗中被广泛应用,但在一些低风险择期手术前对患者进行常规检查,对提高医疗质量并无帮助,反而降低了医疗效率,增加了医疗费用。为提高效率,一些地区、机构和专家学者陆续通过宣传教育、发表共识、制定指南等方式控制无指征术前常规检查,但效果仍依赖于执业者的重视程度和专业水平。大数据机器学习方法以其标准化、自动化的特点为解决这一问题提供了新的思路。在回顾已有研究的基础上,我们抽取2017至2019年在中山大学中山眼科中心进行眼科手术的3.4万名患者的病史和体格检查资料大数据,涵盖年龄、性别等口学信息,诊断、既往疾病等病史信息,视功能、入院时身体质量指数(BMI)等体格检查信息。并以此为基础使用机器学习方法预测术前胸部X线检查是否存在异常,受试者操作特性曲线(receiver operating characteristic curve,ROC)曲线下面积达到0.864,预测准确率可达到81.2%,对大数据机器学习精简术前常规检查的新方式进行了先期探索。
Preoperative routine tests are widely prescribed in clinical settings. However, these tests do not help improving the quality of medical care in low-risk elective surgery. Instead, they are associated with lower efficiency and increasing fees. To improve the efficiency, many regions, institutions, and scholars have attempted to reduce preoperative routine tests without indications through propaganda, education, consensus, and guidelines. Nevertheless, the effects are still highly dependent on the expertise and emphasis of practitioners. Machine learning based on big data provide a new solution with its standardization and automation. Through literature review, we extracted the big data, including demographic features such as sex and age, histories including diagnosis and chronic diseases, and physical examination features such as visual function and body mass index. A total of 34 000 patients undergone ocular surgeries in Zhongshan Ophthalmic Center, Sun Yat-sen university from 2017 to 2019. Machine learning was adopted to predict the risk of finding abnormalities in chest X-ray examination, with an accuracy of 81.2%. Area under the Receiver Operating Characteristic curve was 0.864. The study could be an early exploration into the field of simplifying preoperative tests by machine learning.
