目的：探讨高度近视合并白内障患者白内障术后有效晶状体位置的变化。方法：收集白内障超声乳化摘除联合人工晶状体植入术的高度近视合并白内障患者 21 例共 27 眼，记录术后 1 d、1 周、1 个月视力、屈光度、有效晶状体位置。结果：高度近视合并白内障患者术后 1 d、1 周、1 个月有效晶状体位置分别为（4.17±0.39），（4.09±0.38），（4.31±0.44） mm，且组间比较差异有统计学意义（P < 0.05）。有效晶状体位置的实际轴向运动为（0.19±0.13） mm，与晶状体厚度呈正相关（r = 0.648，P < 0.001），与术前眼轴无相关关系（r = 0.227，P = 0.255）。结论：高度近视合并白内障患者术后 1 d 至 1 周人工晶状体轻度前移而造成近视偏移，而术后 1 个月时则呈远视偏移，且术后有效晶状体位置位移与术前晶状体厚度相关。

Objective: To investigate the change and influencing factors of the effective lens position after cataract surgery in high myopia eyes. Methods: We collected 27 eyes of 21 patients with high myopia who underwent phacoemulsification and intraocular lens implantation. The visual acuity, diopter and effective lens position were recorded 1 day, 1 week, and 1 month after operation. Results: The effective lens position of high myopia combined with cataract patients at 1 day, 1 week, and 1 month was (4.17±0.39), (4.09±0.38), and (4.31±0.44) mm, respectively. The effective lens positions significantly differed between the groups after surgery (P < 0.05). The ELPRMS was (0.19±0.13) mm. The ELPRMS was positively correlated with the lens thickness (r = 0.648, P < 0.001),whereas was not correlated with the preoperative axial length (r = 0.227, P = 0.255). Conclusion: High myopic patients with cataract have a slight forward movement of the effective lens position from 1 day to 1 week after surgery, and a hyperopic shift from 1 week to 1 month. The displacement of effective lens position after surgery is correlated with the preoperative lens thickness.

Methods: This was a prospective case-control study. We collected 1 000 myopic patients (2 000 eyes) who were scheduled to undergo refractive surgery in Aier Eye Hospital. They were examined by 200-degree ultra-wide field laser ophthalmoscope (Daytona) with non-mydriasis and three-mirror contact lens with mydriasis. The examination results were recorded and statistically analyzed. Results: A total of 230 cases (310 eyes) with peripheral retinopathy were found by 200-degree ultra-wide field laser ophthalmoscope (Daytona). The positive rate was 15.50%; 242 cases (322 eyes) with peripheral retinopathy were found by threemirror contact lens, and the positive rate was 16.10%. The two methods were consistent in the detection of peripheral Retinopathy in myopic patients (the Kappa value is between 0.8 and 1.0). Conclusion: 200-degree ultra-wide field laser ophthalmoscope (Daytona) is an effective and rapid method for detecting peripheral retinopathy. It provides a broad clinical application prospects for peripheral retinopathy screening before refractive surgery. 

教学查房是手把手教学的重要手段和具体表现，是让同学们把书本知识应用到医疗诊疗中的重要桥梁。眼科学具有形象生动、结构复杂、直观性和操作性强等特点。外眼疾病的特征更是显而易见，针对外眼疾病诊疗中的一些不规范的操作也更易暴露出来。本文以上睑下垂为例，旨在阐明教学查房在外眼疾病教学中的重要性。

Teaching rounds are an important means and concrete manifestation of hands-on teaching, and an important bridge for students to apply book knowledge to medical diagnosis and treatment. Ophthalmology has the characteristics of vivid image, complex structure, intuition and strong operability. The characteristics of external eye diseases are more obvious, and some non-standard operations in the diagnosis and treatment of external eye diseases are easier to expose. This article takes blepharoptosis as an example to illustrate the importance of teaching rounds in the teaching of external eye diseases.

后极部中心性脉络膜营养不良是一种罕见疾病。本文对 2 例患者进行了荧光素眼底血管造影、眼底自发荧光、相干光层析成像及视觉电生理等检查。眼底检查可见双侧后极部血管弓范围视网膜色素上皮（retinal pigment epithelium，RPE）及脉络膜毛细血管的对称性萎缩。自发荧光可见相应区域的对称性低荧光。光学相干断层成像术（optical coherence tomography，OCT）显示后极部外层视网膜和脉络膜毛细血管的萎缩变薄。

Posterior polar central choroidal dystrophy is a rare disease. Clinical data of two patients with posterior polar central choroidal dystrophy fluorescein angiography, fundus autofluorescence (FAF) imaging, optical coherence tomography (OCT), and electrophysiological tests were reported. Fundus examination showed bilateral symmetric atrophy of the retinal pigment epithelium and choriocapillaris in the posterior polar areas between vascular arcades. FAF imaging showed clearly defined hypoautofluorescent areas that corresponded to the aforementioned lesions. Atrophy of the choriocapillaris and outer retinal layer were detected by optical coherence tomography.

强直性瞳孔在临床工作中较为少见，容易被误诊，典型的强直性瞳孔为单侧，随着病程的进展，逐渐转变为双侧。新发双侧强直性瞳孔更是极为罕见，应当引起重视。其典型的临床表现包括瞳孔散大、瞳孔运动迟钝、节段性瞳孔麻痹、无其他眼部器质性病变。依据病因可以分为继发于急性眼内肌麻痹、合并有全身疾病以及特发性三类。目前治疗方面多以病因治疗为主。

Tonic pupil is rare in clinical work and likely to be misdiagnosed. The typical tonic pupil is unilateral, which gradually turns to bilateral with the progress of disease. Newly bilateral tonic pupil is extremely rare, which captivates widespread attention. Typical clinical manifestations include dilated pupils, slow pupil movement, segmental pupillary palsy, and no other ocular diseases. On this basis, the causes can be divided into three categories, including secondary to acute intraocular myoparalysis, complicated with systemic disease and idiopathic type. At present, etiological treatment is the main treatment.

目的：比较学生在不同散光欠矫下使用C字视力表和E字视力表所测的视力差别并分析其原因。

方法：选取 30 名 15~18 岁的学生，在完全矫正屈光度 MPMVA（maximum plus to maximum visual acuity）状态下，附加相应不同散光轴向的柱镜造成相应的散光度数后，比较使用两种不同的视力表测出的视力值。同时根据两种视力表不同的设计原理及记录方法，分析造成数值差异的可能原因。

结果：与 E 字视力表组相比，C 字视力表组附加各个轴向 +0.25 DC 柱镜组测得视力值均值差异较小，附加 +0.50 DC 差异较大，其中斜轴方向上的差异更大，差异有统计学意义（F = 23.141，P < 0.01）。在各个附加度组别中使用 C 字视力表测得视力平均值小于 E 字视力表测得视力平均值，其中斜轴方向的附加组差值更大。C 字视力表在各散光轴位测得视力值差异无统计学意义（F = 1.446，P = 0.231）；E 字视力表组在各散光轴位测得视力值相差明显，在斜轴散光中数值与非斜轴散光数值差异有统计学意义。

结论：散光患者使用 C 字视力表更加优异，不同轴向的散光测出来的视力值更加稳定。对于非斜轴散光患者来说，使用 C 字视力表比 E 字视力表更难，用小数记录法记录视力值可能相差 3 ~ 4 行，原因为散光眼在各个方向上的屈光度不一致及 C 字视力表和 E 字视力表的视标形状及排列不同导致。

Objective: To compare the differences of visual acuity measured by C-chart and E-chart under different astigmatism and analyze the reasons for the differences.

Methods: Thirty students aged 15–18 years were selected. Under the condition of fully corrected refractive MPMVA (maximum plus to maximum visual acuity)，the corresponding astigmatism was caused by adding corresponding columnar lenses with different astigmatism axes. The corresponding visual acuities measured by two different visual charts. According to the design principle and recording methods of two kinds of visual acuity charts, the possible reasons for the different values are analyzed.

Results: Compared with the E-type visual acuity chart, the average difference of visual acuity measured by adding each axis +0.25 DC columnar lens group was smaller, and the difference between adding +0.50 DC group was larger, especially in the oblique axis direction（F = 23.141，P < 0.01）。The average visual acuity measured by the C-type visual acuity chart in each additional degree group was smaller than that measured by the E-type visual acuity chart, and the difference of the additional group in the oblique axis direction was greater than that measured by the E-type visual acuity chart. There was no significant difference in the visual acuity measured by C-type chart at different astigmatism axes（F = 1.446，P = 0.231）；there was a significant difference in the visual acuity values measured by E-type chart at different astigmatism axes, and there was a significant difference in the values of oblique astigmatism and non-oblique astigmatism.

Conclusion: Astigmatism patients with C-type chart obtain more accurate results, and the visual acuity values measured by different axes of astigmatism are more stable. For patients with non-oblique astigmatism, it is more difficult to use C-type chart than E-type chart. The difference of visual acuity recorded by decimal recording method may be 3–4 rows. The reasons are the inconsistency of diopter in different directions of astigmatism and the different shape and arrangement of visual icons between C- and E-type charts.
