Terson综合征又称蛛网膜下腔出血合并玻璃体积血综合征，是一种较为罕见的眼科疾病。患者多因颅内出血而存在意识障碍、沟通困难，极易漏诊，错过最佳治疗时机。该文报道了一例30岁男性患者，因弥漫蛛网膜下腔出血，突发昏迷，于发病1个月后出现双眼视物模糊，最终确诊为双眼Terson综合征，并行双眼玻璃体切割术及右眼视网膜前膜剥膜术治疗。术后54 d，患者左眼视力由指数/5 cm恢复至矫正视力0.3。术后19 d，患者右眼视力由手动/20 cm恢复至矫正视力0.12。

Terson syndrome, also known as subarachnoid hemorrhage combined with vitreous hemorrhage syndrome, is a relatively rare ophthalmic condition. Patients mostly have impaired consciousness and communication difficulties due to intracranial hemorrhage, which makes it very easy to miss the diagnosis and the best time for treatment. This article reports the basic case of a 30-year-old male patient with sudden coma due to diffuse subarachnoid hemorrhage. And he had blurred vision in both eyes 1 month later, which was finally diagnosed as binocular terson syndrome. He was treated with vitrectomy in the left eye and vitrectomy + anterior retinal detachment surgery in the right eye. The visual acuity of patient was restored from finger count/5cm to corrected visual acuity of 0.3 in the left eye when 54 days after surgery and from manual/20 cm to corrected visual acuity of 0.12 in the right eye when 19 days postoperative.

In this case reportit describes a novel technique using indocyanine green gel for the surgical excision of conjunctival lymphangiectasia (CL). CL was found on the nasal side of left eye in a 50-year-old male. Surgical excision of the entire cystic lesion with an intact cyst wall was completed with the assistance of an indocyanine green (ICG) gel. No sutures were used throughout the entire procedure. Subsequent post operative follow-up was uneventful. Herein, we report a novel technique used to facilitate the identifcation and complete removal of an intraocular cystic lesion ensuring an intact cyst wall.

目的：评估远视儿童使用1%阿托品凝胶1周后脉络膜厚度(choroidal thickness,CT)的变化。方法：选择42例4~7岁的远视儿童，予每天使用1%阿托品凝胶两次，持续7d。使用光学相干断层成像扫描测量视网膜及CT，并分析使用1%阿托品凝胶前后中心凹以及距中心凹处间隔1.0 mm的上、下、鼻和颞侧(最多3.0mm)CT的变化。结果：在远视儿童中，基线CT随位置而变化(F=27.08, P<0.05)，与中心凹相比，鼻侧及距中心凹上方2 mm、3 mm及距中心凹颞侧3 mm处的CT较薄(P<0.05)。使用1%阿托品凝胶后，中央凹及旁中心凹CT改变比较差异无统计学意义(P＞0.05)。使用1%阿托品凝胶前后视网膜厚度无明显变化(P＞0.05)。结论：短期使用1%阿托品凝胶并没有改变远视儿童的脉络膜和视网膜厚度。

Objective: To assess changes of choroidal thickness (CT) in hyperopia children after 1 week using of 1% atropine.Methods: A total of 42 hyperopia children aged 4–7 years were included into the study.A single drop of 1% atropinegel was used twice a daily for 7 days in the subjects.The thickness of retina and choroid was measured by OCT, and the changes before and after using 1% atropine gel were analyzed at the subfovea and at 1.0 mm intervals (up to3.0 mm) from the fovea at superior, inferior, nasal, and temporal locations. Results: In the hyperopia children, baselineCT parameters were varied with the location(F=27.08,P<0.05).Compared with the fovea, the CT at the nasal side,2 mm and 3 mm above the fovea and 3 mm from the temporal side of the fovea were thinner (P<0.05).After using 1%atropine gel, there was no significant difference in the CT changes of subfoveal choroidal thickness and other sites ofparafovea (P> 0.05). There was no significant change in retinal thickness before and after using 1% atropine gel (P > 0.05).Conclusion: No changes were found in the thickness of choroid and retina in hyperopia children after short-term use of1% atropine gel.

Although amniotic membrane transplantation (AMT) has long been used as an essential surgical technique for ocular surface reconstruction, its role continues to evolve and expand. In the management of numerous ocular surface disorders, ranging from inflammatory to infectious, traumatic to neoplastic, the ability to perform AMT is a valuable addition to the skillset of any ophthalmologist. The purpose of this paper is to provide ophthalmologists with an updated, evidence-based review of the clinical indications for AMT in corneal and conjunctival reconstruction, reviewing its common and even experimental applications known to date. The methods of amniotic membrane preservation, the available commercial amniotic membrane products to date, and future directions for amniotic membrane use, including amniotic membrane extract eye drops (AMEED), are also discussed. It is paramount for ophthalmologists to stay up-to-date on the applications of AMT so as to effectively incorporate this versatile treatment modality into their practice,both in the operating room and in the clinic. By familiarizing the general ophthalmologist with its diverse applications, we hope to motivate general ophthalmologists to incorporate the use of AMT into their clinical practice, or provide guidance on how to recognize when referral to a corneal specialist for amniotic membrane application is prudent.

目的：了解湿性老年性黄斑变性(age-related macular degeneration,AMD)患者自我感受负担(self-perceived burden,SPB)现状及其影响因素。方法：采用方便抽样法选取2021年1月至11月在中山大学中山眼科中心就诊的204例湿性AMD患者为研究对象，采用一般资料调查表、SPB量表、家庭支持自评量表、医学应对问卷对其进行测评。结果：患者SPB得分是(21.98±6.68)分，总体属于轻度SPB。湿性AMD患者的SPB水平与家庭支出(r=?0.326, P<0.001)和面对应对(r=?0.365, P<0.001)呈负相关，与回避(r=0.456, P<0.001)及屈服(r=0.310, P<0.001)应对方式呈正相关性。多重线性回归显示，独居、高龄、自费、双眼患病及采用回避应对的患者的SPB更高，而高文化水平、高家庭支持的患者SPB较轻。结论：湿性AMD患者有轻度SPB，但仍存在改善空间，医护工作者在工作中应重点关注高龄、文化程度低、家庭收入低、自费、独居、双眼患病及低视力的患者，及时进行心理疏导，减轻患者的SPB水平。

Objective: To understand the current status and influencing factors of self-preceived burden (SPB) in patients with wet age-related macular degeneration (AMD). Methods: 204 patiens with wet AMD who were treated in Zhongshan Ophthalmic Center, Sun Yat-sen University from January to November 2021 were enrolled as the study subjects with convenience sampling method. A general information questionnaire, SPB scale, family support self-assessment scale, and medical coping questionnaire were collected from the subjects for assessment. Results: The patient’s SPB score was 21.98±6.68, which is generally mild SPB. The SPB level of patients with wet AMD was negatively correlated with family support (r=-0.326, P<0.001) and coping (r=?0.365, P<0.001), and were positively correlated with avoidance (r= 0.456,P<0.001), and surrender (r=0.310, P<0.001) coping style. Multiple linear regression showed that the patients who lived alone, were elder and self-funded, had binoclur diseases and used avoidance coping, had higher SPB. While the patients with high education and family support had lower SPB. Conclusions: It is still needed to pay attention to the patients with AMD having mild SPB. Medical workers should focus on patients with elder age, low education level, low family income, self-funded, living alone, binocular disease and low vision in their work, and provide timely psychological counseling to reduce the SPB level of patients.

外泌体(exosome)是直径30 nm~150 nm的纳米级囊泡，由脂质双分子层、蛋白质和遗传物质组成。人体内几乎所有类型的细胞都能分泌外泌体。它们在细胞通信、免疫调节、炎症反应和新生血管形成中起着关键作用。目前，外泌体已在肿瘤、心血管及泌尿系统中得到广泛研究。近年来，外泌体在眼科疾病中的作用受到越来越多的关注。外泌体在角膜病变、年龄相关性黄斑病变、糖尿病视网膜病变、青光眼等常见眼科疾病的发生、发展中发挥重要作用。不同间充质干细胞来源的外泌体在眼科疾病中的治疗潜力是当下的热点。间充质干细胞来源的外泌体具有与间充质干细胞相似的抗炎、抗凋亡、神经保护和组织修复的作用，因此外泌体可能是多种眼科疾病无细胞疗法治疗研究的新方向。进一步了解外泌体的生物学特性以及外泌体在眼科疾病的最新研究进展，将为相关眼病的发生机制和防治策略提供参考依据。

Exosomes are nanoscale vesicles with a diameter of 30 nm to 150 nm, which are composed of lipid bilayers, proteins, and genetic material. Almost all types of cells in the human body can secrete exosomes. Tey play key roles in cellular communication, immune regulation, infammatory responses and neovascularization. At present, exosomes have been widely studied in tumors, cardiovascular and urinary systems. In recent years, the role of exosomes in eye diseases has attracted more and more attention. The exosomes play an important role in the occurrence and development of common eye diseases such as keratopathy, age-related macular disease, diabetic retinopathy, glaucoma, etc. Currently it is a hot topic that the therapeutic potential of extracellular vesicles derived from diferent mesenchymal stem cells in eye  diseases. Te exosomes derived from mesenchymal stem cells have anti-infammatory, anti apoptotic, neuroprotective and tissue repairing effects, which are similar to those of mesenchymal stem cells. Thus, exosomes may be a novel direction of research in the treatment of many eye diseases without cell therapy. Further understanding of the biological characteristics of exosomes and the latest research progress of exosomes in common eye diseases will provide reference for the pathogenesis and prevention strategies of related eye diseases.

甲状腺相关眼病是一种器官特异性自身免疫性疾病，其发病机制复杂，是成人最常见的眼眶疾病，且发病率逐年升高。该病不仅会导致眼球突出、眼睑退缩、睑裂扩大、眼球运动障碍等外观上的变化，且患者往往伴发眼红、眼痛、干涩、异物感、复视、视力下降等不适症状，其中眼表疾病的发病率较正常人明显增高，但其具体发病机制尚待进一步挖掘。目前研究表明甲状腺相关眼病患者的眼表损伤主要与眼表暴露增加、炎症侵犯、激素改变有关。角膜、结膜、泪膜、睑板腺等组织受累发生病理改变是患者表现出不同临床症状的直接原因。文章通过分析近年来国内外关于甲状腺相关眼病与眼表疾病等方面的相关研究，针对甲状腺相关眼病眼表损伤的病理改变及机制研究进展做一综述。

Tyroid-associated ophthalmopathy is an organ-specifc autoimmune disease with complex pathogenesis. It is the most common orbital disease in adults, and its incidence increases year by year. Tis disease can not only lead to appearance changes such as eyeball protrusion, eyelid retraction, eyelid cleat enlargement, eye movement disorders, and patients are ofen accompanied by red eyes, eye pain, dryness, foreign body sensation, diplopia, vision loss and other uncomfortable symptoms, among which the incidence of ocular surface diseases is signifcantly higher than that of normal people, but its specifc pathogenesis needs to be further explored. Current studies have shown that ocular surface injury in patients with thyroid-associated ophthalmopathy is mainly related to increased ocular surface exposure, infammatory invasion, and hormonal changes. Te pathological changes of cornea, conjunctiva, tear flm, meibomian gland and other tissues involved are the direct causes of different clinical symptoms of patients. In this paper, through the analysis of recent domestic and foreign studies on thyroid-associated ophthalmopathy and ocular surface diseases, the pathological changes and mechanism of ocular surface injury in thyroid-associated ophthalmopathy were reviewed.

外伤性视神经病变是因外力损伤视神经，进而严重损害视力的致盲性眼病。自噬是一种细胞内降解途径，有助于维持细胞正常组分合成与受损细胞器及有毒细胞成分的分解之间的平衡。视神经受创后，视神经和视网膜中自噬标志物增加。自噬在外伤性视神经病变的不同阶段对视网膜神经节细胞可能起不同作用。多数研究表明，上调自噬可以减轻外伤性视神经病变中视网膜神经节细胞的死亡；也有研究提示在视神经损伤后极早的时期抑制自噬可以抑制视网膜神经节细胞轴突变性。该文对自噬的定义及功能、自噬的发生机制、视神经创伤后自噬水平改变、自噬在视神经创伤后对视网膜神经节细胞的作用的研究结果进行综述。

Traumatic optic neuropathy is a blinding eye disease that causes severe damage to vision due to external force damage to the optic nerve.. Autophagy is an intracellular degradation pathway that helps maintain the balance between the synthesis

of normal cell components and the breakdown of damaged organelles and toxic cellular components. Autophagy markers are increased in optic nerve and retina after optic nerve trauma. Autophagy may play different roles on retinal ganglion cells (RGCs) at different stages of traumatic optic neuropathy. Most studies have shown that upregulating autophagy can attenuate RGCs death in traumatic optic neuropathy; however, it has also been suggested that inhibition of autophagy at ultra-early stage after injury can inhibit RGCs axonal degeneration. In this review, we reviewed the definition and function of autophagy, the mechanism of autophagy, and summarized the change of autophagy level after optic nerve trauma, as well as the effects of autophagy in RGCs after optic nerve trauma.

渐进性视功能障碍多见于屈光不正、原发性开角型青光眼、白内障、视神经视网膜遗传代谢性疾病等，少见于眶内和颅内占位性疾病。颅内蛛网膜囊肿通常是无症状的先天性良性病变，少数出现视功能障碍。 视神经管骨壁缺如见于后组筛窦和蝶窦气化良好的正常人。该文报告 1例59岁男性患者，因左眼视野缺损伴视物模糊1年余就诊，确诊左侧颞极蛛网膜囊肿合并视神经管骨壁缺如。笔者通过收集该患者的病史、影像学资料和视功能检查结果，分析其出现视功能障碍的机制。

Progressive visual impairment is more common in ametropia, primary open-angle glaucoma, cataract, hereditary and metabolic diseases of optic nerve and retina, and less common in orbital and intracranial masses. Intracranial arachnoid cysts are usually asymptomatic benign congenital lesions with a small number of visual impairments. The absence of the bone wall of the optic canal was seen in normal subjects with good gasification of the posterior ethmoid sinus and sphenoid sinus. In this case report we describe a 59-year-old man with a left temporal arachnoid cyst and a defect of the bone wall of the optic canal complained of left visual field defect and blurred vision for more than one year. The mechanism of visual dysfunction was analyzed by collecting the patient’s medical history, imaging data and the results of visual function examination.
