目的：开发一款可自动校准测试距离的智能手机视力检测APP(WHOeye的iOS版本)，并评估其实用性。方法： WHOeyes在经过验证的视力检测APP “V@home”的基础上新增自动距离校准(automatic distance calibration, ADC)功能。研究招募了3组不同年龄(≤20岁、20~40岁、>40岁)的中国受试者，分别使用糖尿病视网膜病变早期治疗研究(Early Treatment Diabetic Retinopathy Study, ETDRS)视力表和WHOeyes进行远距离和近距离的视力检测。ADC功能用于确定WHOeyes的测试距离。红外测距仪用于确定ETDRS的测试距离以及WHOeyes的实际测试距离。通过问卷调查评估用户满意度。结果：WHOeyes ADC确定的实际测试距离在3个年龄组中均与预期测试距离总体上表现出良好的一致性(P > 0.50)。在远距离和近距离视力检测方面，WHOeyes的准确性与ETDRS相当。WHOeyes与ETDRS之间的平均视力差异范围为–0.084 ~ 0.012 log^MAR，各组的二次加权卡帕系数(quadratic weighted kappa, QWK)均大于0.75。WHOeyes在近距离和远距离视力检测中的重测信度高，平均差异范围为–0.040 ~ 0.004 log^MAR，QWK均大于0.85。问卷调查显示WHOeyes具有较好的用户体验和接受度。结论：与金标准ETDRS视力表方法相比，WHOeyes测试距离较为准确，可以提供准确的远距离和近距离视力测量结果。

Background: To develop and assess usability of a smartphone-based visual acuity (VA) test with an automatic distance calibration (ADC) function, the iOS version of WHOeyes. Methods: The WHOeyes was an upgraded version with a distinct feature of ADC of an existing validated VA testing APP called V@home. Three groups of Chinese participants with different ages (≤20, 20-40, >40 years) were recruited for distance and near VA testing using both an Early Treatment Diabetic Retinopathy Study (ETDRS) chart and the WHOeyes. The ADC function would determine the testing distance. Infrared rangefinder was used to determine the testing distance for the ETDRS, and actual testing distance for the WHOeyes. A questionnaire-based interview was administered to assess satisfaction. Results: The actual testing distance determined by the WHOeyes ADC showed an overall good agreement with the desired testing distance in all three age groups (p > 0.50). Regarding the distance and near VA testing, the accuracy of WHOeyes was equivalent to ETDRS. The mean difference between the WHOeyes and ETDRS ranged from -0.084 to 0.012 log^MAR, and the quadratic weighted kappa (QWK) values were greater than 0.75 across all groups. The test-retest reliability of WHOeyes was high for both near and distance VA, with a mean difference ranging from -0.040 to 0.004 log^MAR and QWK all greater than 0.85. The questionnaire revealed an excellent user experience and acceptance of WHOeyes. Conclusion: WHOeyes could provide accurate measurement of the testing distance as well as the distance and near VA when compared to the gold standard ETDRS chart.

目的：调查眼科学硕士研究生批判性思维能力的现况，并了解其相关因素。方法：采用中文版评判性思维能力测量表(Critical Thinking Disposition Inventory-Chinese Version, CTDI-CV)对81名眼科学硕士研究生进行问卷调查，比较不同性别、年级、学位类别、学制的学生批判性思维能力的差异。结果：81名眼科学硕士研究生的CTDI-CV总分为(294.79±29.18)分，表明普遍具备积极的批判性思维能力，但“寻找真相”和“系统化能力”得分较低；不同年级与学位类型的眼科学硕士研究生的批判性思维能力等级分布存在差异。多因素线性回归显示，学位类型与眼科学硕士研究生的批判性思维能力相关。结论：眼科学硕士研究生普遍展现出正性的批判性思维特质，但在特定领域，其批判性思维能力仍有待提高，研究生教育应当采取针对性措施，培养研究生的批判性思维能力。

Objective: To investigate the current situation of critical thinking abilities of masters’ degree postgraduates in ophthalmology and identify the factors affecting the critical thinking abilities. Methods: Using the Critical Thinking Disposition Inventory-Chinese Version (CTDI-CV), a questionnaire survey was conducted among 81 masters’ degree postgraduates in ophthalmology. Results: The average total score of the CTDI-CV for the 81 master’s degree postgraduates in ophthalmology was 294.79±29.18, indicating a general possession of positive critical thinking abilities, yet scores in “Truth Seeking” and “Systematicity” were relatively low. There are differences in critical thinking abilities among master’s degree postgraduates in ophthalmology of various grades and degree categories. Multivariate linear regression indicates that degree categories is correlated with the critical thinking abilities of ophthalmology graduate students. Conclusions: The masters’ degree postgraduates in ophthalmology generally exhibit positive traits of critical thinking, yet there is room for improvement in specific areas. Postgraduate education should adopt targeted measures to cultivate the critical thinking abilities of postgraduates.

前段巨眼(anterior megalophthalmos, AM)是一种罕见的双侧非进展性先天性眼前段增大疾病，表现为大角膜(直径≥ 12.5 mm)、前房极深、角膜厚度正常或轻中度变薄和睫状环扩大等。并发性白内障以及晶状体脱位是导致AM视力下降的主要原因。然而，解剖结构的异常使AM白内障手术具有很大的挑战性。文章报道了一例AM合并白内障的48岁男性患者，成功为其行手法小切口白内障摘除联合人工晶状体(intraocular lens, IOL)一期植入术，患者术后视力恢复良好，IOL位置居中，未出现较大的屈光误差。对该典型AM病例的临床特点以及手术难点的回顾总结，有助于加深广大眼科临床工作者对该疾病的认识。

Anterior megalophthalmos is a rare congenital enlargement of the anterior segment, characterized by bilateral nonprogressive megalocornea (diameter ≥12.5 mm), extremely deep anterior chamber, normal or moderate thinning of the cornea, and elongation of the ciliary ring. Cataract and lens dislocation are the main causes of decreased vision in patients with AM. However, cataract surgery on patients with AM are challenging due to the anatomical abnormalities. This case reports a 48-year-old male patient diagnosed with AM and cataract, who successfully underwent a manual small incision cataract extraction combined with intraocular lens implantation. Finally, our patient showed a good visual outcome with a well centered IOL and without obvious refractive error. In this typical AM case, we reviewed and summarized the clinical characteristics and the challenges of surgical treatment so that other ophthalmologists can learn about this disease.

红光是波长范围在620~760 nm的可见光，兼有良好的光化学和热作用，其穿透力较强，能够达到皮肤深层及组织内部，从而产生一系列的生物效应。在眼科领域，红光疗法最初主要应用于弱视和眼睑皮肤相关疾病的治疗，随着研究的进一步深入，红光逐渐被应用于控制近视进展和视网膜相关疾病。目前，重复低强度红光(repeat low-level red-light, RLRL)在近视进展的控制效果得到充分肯定，成为红光疗法在眼科应用最受关注的热点之一，其主要可能机制包括红光照射能激活线粒体中的细胞色素C氧化酶的活性，促进三磷酸腺苷(adenosine triphosphate, ATP) 生成，改善网膜缺氧状况；促进一氧化氮 (nitric oxide, NO)的合成和释放，引起脉络膜血管的扩张及血流量的增加；诱导巩膜细胞外基质的重塑，增加巩膜的强度。此外，红光疗法可抑制视网膜感光细胞调节通路中的氧化应激、炎症和细胞凋亡，减轻眼表炎症反应和疼痛，有助于周围神经损伤后修复等。文章针对红光疗法在近视、视网膜相关疾病、弱视及眼睑皮肤相关疾病的治疗机制、有效性及安全性进行综述，为红光疗法在眼科领域的应用提供重要的参考价值和依据。

Red light is visible light with a wavelength range of 620-760 nm, which has excellent photochemical and thermal effects. It can penetrate deeply into the skin and tissues with strong power, resulting in a series of biological effects. In the field of ophthalmology, red-light therapy was initially mainly used in the treatment of amblyopia and eyelid skin-related diseases, and with the further development of research, red light has been gradually used in the myopia control and the study of retina-related diseases. At present, the effect of repeated low-intensity red light (RLRL) on myopia progression has been fully recognized, and it has become one of the most concerned hotspots in the application of red-light therapy in ophthalmology. The main possible mechanisms include that red light therapy can activate the activity of cytochrome C oxidase in mitochondria, promote ATP production, and improve retinal hypoxia. It can also induce the synthesis and release of NO, cause the expansion of choroidal vessels with improvement of blood flow, and increase scleral strength by remodeling of scleral extracellular matrix. In addition, red- light therapy can reduce oxidative stress, inflammation and apoptosis in the regulatory pathways of photoreceptor cells, reduce eye inflammation and pain, and help repair peripheral nerves after injury. This article will review the mechanism, effectiveness and safety of red-light therapy in myopia, retinal diseases, amblyopia, and eyelid skin-related diseases, in order to provide important reference value and basis for the application of red-light therapy in ophthalmology.

内源性真菌性眼内炎(endogenous fungal endophtalmitis, EFE)是最具破坏性的眼部感染之一，在临床上较少见。如诊断和治疗不及时，可严重损害患者视力，甚至需摘除眼球。由于EFE发病隐匿，病程较长，病原学涂片和培养阳性率较低，早期临床症状与葡萄膜炎相似，极易被误诊和漏诊，延误治疗时机。EFE最常见的感染灶来源为肝脏、肺、尿路、脑膜炎、胃肠道、心内膜以及骨髓。文章报道了一例腰椎感染致双眼内源性念珠菌性眼内炎的男性患者，66岁，因“右眼视力下降1周”首诊于眼科，专科检查见右眼玻璃体炎性混浊，初诊为右眼葡萄膜炎，予抗炎等治疗症状无好转，右眼视力持续下降，右眼前房穿刺抽液送检提示：热带念珠菌感染，之后左眼视力也逐渐下降，加之患者近期于骨科住院，术中腰椎间盘退变的纤维软骨组织DNA-病原微生物宏基因组检测结果示热带念珠菌，考虑双眼EFE，予全身及局部使用抗真菌药物联合双眼玻璃体切割手术，治疗后患者视力恢复良好，随访1年无复发。该病例及相关文献回顾，有助于加深临床医生对此类疾病的认识，为今后临床诊疗提供一定思路，也起到一定警示作用。

Fungal endophthalmitis is one of the most destructive eye infections and is relatively rare in clinical practice.If not diagnosed and treated promptly, it can severely damage vision and even lead to enucleation.Due to its insidious onset, long course, low positive rates in smears and cultures, and early clinical symptoms similar to uveitis, it is prone to misdiagnosis and missed diagnosis, leading to delayed treatment. A review of the literature indicates that the most common sources of EFE infection are the liver, lung, urinary tract, meningitis, gastrointestinal tract, endocarditis and osteomyelitis.In this paper, we report a case of lumbar spine infection causing bilateral candidal endophthalmitis in a 66-year-old male patient.He initially presented to the ophthalmology department of our hospital with a one-week history of decreased vision in the right eye, specialized examination revealed inflammatory opacity in the vitreous of the right eye, initially diagnosed as uveitis and treated with anti-inflammatory therapy without improvement.As the vision in the right eye continued to decline, aqueous humor aspiration from the anterior chamber of the right eye indicated infection with tropical Candida.Subsequently, the vision in the left eye also gradually decreased.Considering the recent hospitalization in the orthopedic department for lumbar disc degeneration, metagenomics analysis of fibrous cartilage tissue DNA during surgery detected tropical Candida, suggesting bilateral endogenous fungal endophthalmitis,The patient was treated with systemic and local antifungal medications in combination with bilateral vitrectomy surgery.After treatment, the vision recovered well, and there was no recurrence during a one-year follow-up.The objective of this thesis is to deepen the understanding of clinicians on this type of disease by reporting this case and reviewing relevant literature, providing some insights for future clinical diagnosis and treatment, and serving as a warning.

前段巨眼(anterior megalophthalmos, AM)是一种罕见的双侧非进展性先天性眼前段扩大疾病，表现为大角膜、角膜厚度正常或轻中度变薄、前房明显加深、睫状环扩大和悬韧带松弛。早期症状可仅表现为角膜散光和屈光不正等，并发性白内障和晶状体脱位是AM患者视力下降的主要原因。眼前段解剖结构的异常使AM患者的白内障手术具有很大的挑战性。首先，极端前房深度引起的有效晶状体位置(ELP)预测误差及公式选择不当是导致其术后较大屈光误差的主要原因；其次，悬韧带松弛易导致晶状体脱位、后囊膜破裂和玻璃体脱出等术中并发症的发生；由于超大囊袋及悬韧带松弛，人工晶状体(IOL)偏心甚至脱位也是术后常见的并发症。因此，需根据患者悬韧带情况、晶状体混浊程度采取合适的手术方式及谨慎选择IOL的类型。采用手法小切口晶状体囊外摘除术，可避免超声乳化的高灌注压对悬韧带的进一步损伤，增加手术的安全性；植入光学面及襻宽大的IOL术后具有较好的稳定性；新公式如Barrett Universal Ⅱ、Kane和EVO等公式具有较好的屈光预测准确性。然而，目前关于AM患者的白内障手术治疗报道仍属于个案报道，未来还需要更大样本量的临床研究进一步证实。
