眼结核的表现形式多样，有时会被误诊漏诊。本病例为一年轻男性，以右眼视力突发下降为主诉就诊，眼部表现可见黄斑区脉络膜占位病灶及视网膜内小病灶，经γ-干扰素释放试验、胸部CT等检查，确诊为血型播散性肺结核，眼部诊断为结核性脉络膜结节联合视网膜结节，全身接受抗结核治疗后，眼部病灶消退。

Ocular tuberculosis encompasses a variety of clinical manifestations, which is easily misdiagnosed sometimes. In this article, a young male was admitted to our hospital with a chief complaint of sudden blurred vision in his right eye. His ocular examination detected a tiny mass in the choroid and a small lesion in the retina. After interferon-gamma release assay (IGRA) and chest CT scan, the patient was diagnosed with military tuberculosis. The ocular examination confirmed the diagnosis of choroidal tubercle complicated with intrarentinal tubercle, which were healed after systemic anti-tuberculosis therapy.

目的：观察急性中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy，CSC)的自然病程中渗漏点的形态及变化。方法：本研究为前瞻性研究，使用光学相干断层扫描(optical coherence tomography，OCT)观察从发病到发病后5~13个月的CSC患者的渗漏点的OCT形态，测量并计算Hall层、脉络膜全层各自厚度及比值，并进行比较。结果：共20例患者[男14例，女6例，年龄33~59(中位数41)岁]纳入研究。随访时间为5~13个月。在19例患者中观察到微小视网膜色素上皮脱离(pigment epithelium detachment，PED)。1例患者可见视网膜色素上皮(retinal pigment epithelium， RPE)小凸起。在随访期间，仅1例患者的PED完全恢复，其他19例患者在视网膜下液被完全吸收时，RPE和Bruch膜之间仍存在微小分离。渗漏点处的Haller层/脉络膜厚度显著高于中央凹处(初诊时0.806±0.08 vs 0.863±0.06，P=0.003；最后1次随访时为0.801±0.07 vs 0.851±0.06，P=0.004)。结论：本研究观察到在急性CSC患者自然病程中，即使视网膜下液吸收，OCT显示渗漏点处仍存在持续的PED，更厚的Haller层及更薄的内层脉络膜，这些发现为CSC的发病机制提供了更多线索。

Objective: To observe the morphology and changes of leakage points in the natural course of acute central serous chorioretinopathy (CSC). Methods: This study was a prospective study, using optical coherence tomography to observe the OCT morphology of leakage points in CSC patients from onset to 5 to 13 months after onset, measuring the thickness and ratio of Hall layer and the whole choroid, and then compare them. Results: A total of 20 patients were included in the study, including 14 males and 6 females, aged from 33 to 59, with the median being 41 years old. The follow-up time ranged from 5 months to 13 months. Minute retinal pigment epithelial detachments (PED) were observed in 19 patients. A small bulge of retinal pigment epithelium (RPE) was observed in 1 patient. During the follow-up, only one patient totally recovered. Small separation between RPE and Bruch membrane still exit even subretinal fluid were absorbed completely in the other 19 patients. The thickness of Haller layer or choroid at the leakage point was significantly higher than that of the fovea (0.806±0.08 vs 0.863±0.06, P=0.003, at the first visit; 0.801±0.07 vs 0.851±0.06, P=0.004, at the last follow-up). Conclusion: This study observed that in the natural course of acute CSC patients, even if the subretinal fluid was absorbed, OCT still showed that there was persistent PED at the leakage point, thicker Haller layer and thinner inner choroid layer. These findings provided more clues to the pathogenesis of CSC.

目的：分析医学人工智能通识课程“眼科人工智能的研发与应用”的开展效果，为相关医学人工智能通识课程的开展提供参考和借鉴。方法：纵向观察性研究。观察分析2020年秋季学期眼科人工智能的研发与应用通识课程学生人群，课程考核结果以及学生对课程的整体评价。结果：共有118名本科生同学参与了课程学习。其中大部分为低年级临床医学专业本科生。期中考核得分为77.21±10.07，有56位同学(47.46%)达到80分以上。期末考核得分为82.24±6.77，有91位同学(77.12%)达到80分以上。同学对课程的评分为98.76±3.55，超过90%的同学表示课程备课认真、授课条理清晰、表达准确。结论：本课程的顺利进展证明医学人工智能联合教学模式的可行性，理论和实践穿插的教学设置帮助同学们更好地掌握知识技术，完成教学目标。

Objective: To analyze the effectiveness of medical education curriculum named “Development and Application of Ophthalmic Artificial Intelligence”, and provide reference for the development of other related curriculums. Methods: Longitudinal observational study method was adopted. During the fall semester of 2020, we conducted an education curriculum named “Development and Application of Ophthalmic Artificial Intelligence” and analyzed the results of mid-term and final examinations, and curriculum evaluation of students. Results: There were 118 undergraduate students taking the course and most of them were junior students majoring in clinical medicine. The score of the mid-term examination was in the range of 77.2±10.07, and 56 students (47.46%) got more than 80 points. The score of the final examination was in the range of 82.24±6.77, and 91 students (77.12%) got more than 80 points. The score of course evaluation of students was in the range of 98.76±3.55, and more than 90% of the students thought that teachers have made full preparations before class, together with clear teaching logic and accurate expressions in class. Conclusion: The smooth progress of our course proved the feasibility of medical artificial intelligence teaching. The teaching setting interspersed with theory and practice could help students to master knowledge and technology better, so as to achieve the teaching objectives.
