ROP is a disease process mostly reported in preterm neonates ranging from mild, transient changes in the retina with regression to severe progressive vasoproliferation, scarring, detachment of retina and blindness and it is common blinding disease in children and a major cause of vision loss among preterm infants [3]. Today it is well known that oxygen therapy is not the single causative factor, but many other risk factors play a causative role in the pathogenesis of ROP [4,5].
ROP是一种主要发生在早产儿的疾病过程,从轻度、短暂的视网膜变化到严重的进行性血管增生、瘢痕形成、视网膜脱离和失明,是儿童常见的致盲疾病,也是早产儿视力丧失的主要原因。今天,众所周知,氧疗不是唯一的致病因素,许多其他危险因素在ROP的发病机制中起着致病作用[4,5]。

Refractive error is a complex and multifactorial condition that varies in prevalence across populations with different genetics, demographics, ocular and extrinsic factors, such as education. The Nigerian National Blindness and Visual impairment Survey [3], indicated that uncorrected refractive error accounts for 57.1% of moderate visual impairment (visual acuity [VA], > 6/18–6/60). Economic consequences are considerable, as uncorrected refractive errors including presbyopia also affect people in the working-age group. Presbyopia is the type of refractive error which occurs due to loss of elasticity of the lens capsule and lens substance; it’s an age-related change and is common all over the world. This article reports on the types of refractive error that occur among patients in the presbyopic age group (35 to 80 years) in Port Harcourt, located in the Niger Delta region of Nigeria. To the best of our knowledge, no such study has been conducted in this locality before for comparison with results from other parts of the country.
屈光不正是一种复杂的多因素疾病,在不同的遗传、人口统计学、眼睛和外在因素(如教育程度)的人群中患病率不同。尼日利亚全国失明和视力障碍调查[3]显示,未矫正屈光不正占中度视力障碍(视力[VA], > 6/18-6/60)的57.1%。由于包括老花眼在内的未矫正屈光不正也影响到工作年龄人群,因此经济后果相当严重。老花眼是由于晶状体囊和晶状体物质失去弹性而发生的一种屈光不正;这是一种与年龄有关的变化,在世界各地都很常见。本文报道了尼日利亚尼日尔三角洲地区哈科特港老花眼年龄组(35 - 80岁)患者的屈光不正类型。据我们所知,在此之前还没有在这个地方进行过这样的研究,以便与该国其他地区的结果进行比较。

Cosmetic blepharoplasty of the upper eyelids has long been a mainstay of aesthetic surgeons and remains one of the most requested functional and aesthetic procedures. Multiple incisional modalities have been used over the years, including scalpel, scissors, electro surgery, radio wave surgery, and CO2 laser [1-12]. Although conventional surgery with scalpel and scissors (i.e., cold incision) produces aesthetic results, it applies skin stretching during incision and leads to enhanced bleeding and increased postoperative edema, ecchymosis, and discomfort [3]. By contrast, radio wave surgery (also designated radiofrequency [RF] surgery or radiosurgery), provides a pressure less incision with no dragging or bunching of tissue (concomitant with an enhanced precision of incision), and a simultaneous cutting and coagulation mode maintains a bloodless surgical ield, with minor risks of postoperative hematoma. However, it does lead to lateral tissue damage caused by heat production in the tissue1. Surprisingly, only a few studies were found comparing these two incision modalities in the same patient [1,2]. Abstract
长期以来,上眼睑整容术一直是美容外科医生的支柱,并且仍然是最需要的功能和美学程序之一。多年来使用了多种切口方式,包括手术刀、剪刀、电手术、无线电波手术和CO2激光[1-12]。虽然使用手术刀和剪刀的常规手术(即冷切口)可以达到美观的效果,但它在切口时施加皮肤拉伸,导致出血增加,术后水肿、瘀斑和不适增加。相比之下,无线电波手术(也被称为射频[RF]手术或放射手术)提供了一个无压力的切口,没有组织的拖曳或聚集(伴随着切口精度的提高),同时切割和凝固模式保持了一个无血的手术野,术后血肿的风险很小。然而,它确实会导致组织中产生热量引起的侧向组织损伤。令人惊讶的是,只有少数研究发现在同一患者中比较这两种切口方式[1,2]。摘要

Purpose: The aim of this study is to report the case of a patient diagnosed with butterfly pattern dystrophy (BPD), which during yearly follow-up visits developed a concomitant pachychoroidal neovasculopathy (PNV). Methods: Case report focusing on the role multimodal imaging in patients with pattern dystrophies (PDs) Case report: We describe a case of a 52-year-old woman,which was initially diagnosed with BPD by fundus examination, fundus autofluorescence and optical coherence tomofraphy findings. Interestingly, during yearly follow-up visits, the presence of a thickened choroid bilaterally associated with the onset of concomitant choroidal neovascularizations (CNVs) in the right eye was made possibile by adopting multimodal imaging, in particular optical coherence tomography angiography. Fluorescein angiography and indocyanine green angiography findings helped us to make the diagnosis of PNV. Conclusion: We described for the first time a case of PD, which after several years progressed to PNV. Hence, we deem that multimodal imaging and in particular optical coherence tomography angiography represent an important diagnostic tool in the management of PDs.
目的:本研究的目的是报告一个被诊断为蝴蝶型营养不良(BPD)的患者,在每年的随访中并发厚脉络膜新生血管病变(PNV)。病例报告:我们描述了一个52岁的女性病例,她最初通过眼底检查、眼底自身荧光和光学相干断层扫描结果诊断为BPD。有趣的是,在每年的随访中,通过采用多模态成像,特别是光学相干断层血管成像,可以发现右眼伴有脉络膜新生血管化(CNVs)的双侧脉络膜增厚。荧光素血管造影和吲哚菁绿血管造影结果帮助我们做出PNV的诊断。结论:我们首次报道了一例PD,几年后发展为PNV。因此,我们认为,多模态成像,特别是光学相干断层血管造影是一个重要的诊断工具,在管理的pd。

Purpose: To determine extracellular thiol homeostasis and intracellular glutathione homeostasis as a plasma biomarker for oxidative stress and to compare these parameters in non-exudative/exudative AMD patients and healthy individuals. Method: 30 non-exudative AMD, 28 exudative AMD, and 36 age-matched healthy control subjects enrolled to the study. Extracellular total thiol, native thiol, disulphide amounts and intracellular oxidized/reduced glutathione levels of subjects were determined, and disulphide/thiol and oxidized/reduced glutathione percent ratios were calculated. Results: In comparison with the control group both non-exudative and exudative AMD patients had higher plasma disulfide levels (20.5(4.8) vs. 4(3.1), p<0.001 and 22.5(7.5) vs. 15.4(3.1), p<0.001; respectively) and higher disulphide/thiol (6.64(2.57) vs. 5.4(1.9), p=0,002 and 7.05(3.14) vs. 5.4(1.9), p<0.001; respectively), in addition to higher oxidized glutathione levels (64.6(40.8) vs. 27.3(21.9), p=0.015 and 73.9(44.1) vs. 27.3(21.9), p=0.002; respectively) and oxidized/reduced glutathione ratio(6.48(8.35) vs. 3.14(3.31), p=0,034 and 10.21(10.28) vs. 3.14(3.31), p=0,003; respectively). Although there was no significant difference between groups in term of total thiol (361.5(61.6), 355.1(87.7) and 340.9(72.4), respectively, p=0,585); native thiol (318.8(62.4), 307.1(73.7) and 299.3(79.2), respectively, p=0,382); total reduced glutathione (986.3(282.1), 871.5(271.6) and 881.8(290.9), respectively, p=0.344) and native reduced glutathione (873.4(367.6), 723.7(379.0) and 797.2(307.5), respectively, p=0,113). However, there was no significant difference between non-exudative and exudative AMD groups in terms of both extracellular thiol homeostasis and intracellular glutathione homeostasis. Conclusion: Greater extent of both extracellular disulphide and intracellular oxidized glutathione production occurred in AMD patients compared to age-matched healthy controls indicates the role of increased oxidative stress in AMD development. Further studies are needed to confirm the pathophysiologic role of homeostasis in these buffer systems in AMD.
目的:测定细胞外硫醇稳态和细胞内谷胱甘肽稳态作为氧化应激的血浆生物标志物,并比较非渗出性/渗出性AMD患者和健康人的这些参数。方法:30例非渗出性AMD, 28例渗出性AMD, 36例年龄匹配的健康对照。测定细胞外总硫醇、天然硫醇、二硫含量和细胞内氧化/还原性谷胱甘肽水平,并计算二硫/硫醇和氧化/还原性谷胱甘肽的百分比比率。结果:与对照组相比,非渗出性和渗出性AMD患者血浆二硫化物水平均较高(20.5(4.8)比4(3.1),p<0.001; 22.5(7.5)比15.4(3.1),p<0.001;较高的二硫/硫醇(6.64(2.57)比5.4(1.9),p= 0.002和7.05(3.14)比5.4(1.9),p<0.001;分别),除了更高的氧化谷胱甘肽水平(64.6(40.8)比27.3(21.9),p=0.015和73.9(44.1)比27.3(21.9),p=0.002;氧化/还原谷胱甘肽比值(6.48(8.35)vs. 3.14(3.31), p= 0.034, 10.21(10.28) vs. 3.14(3.31), p= 0.003;分别)。总硫醇含量分别为361.5(61.6)、355.1(87.7)和340.9(72.4),组间差异无统计学意义(p= 0.585);天然硫醇(318.8(62.4),307.1(73.7)和299.3(79.2),p=0,382);总还原性谷胱甘肽(986.3(282.1)、871.5(271.6)、881.8(290.9),p=0.344)和天然还原性谷胱甘肽(873.4(367.6)、723.7(379.0)、797.2(307.5),p= 0.113)。然而,在细胞外硫醇和细胞内谷胱甘肽的稳态方面,非渗出性和渗出性AMD组之间没有显著差异。结论:与年龄匹配的健康对照相比,AMD患者细胞外二硫化物和细胞内氧化谷胱甘肽的产生程度更高,这表明氧化应激增加在AMD发展中的作用。需要进一步的研究来证实这些缓冲系统在AMD中的病理生理作用。

Introduction: Computer vision syndrome is one of the major public health problems. However, the prevalence and associated factors were unknown among postgraduate students, making provision and intervention treatment more difficult. This study was intended to fill this gap. Methods: An institution-based cross-sectional study was conducted using a pre-tested structured self-administered questionnaire. The data were entered into epidemiological information version 7 and exported to SPSS for analysis. p-value <0.05 was considered statistically significant. Results: A total of 359 students participated in this study, with a response rate of 96.38%. The prevalence of computer vision syndrome was 84.4% (95% CI, 80.10-88.00). Students who used a computer for more than 4.6 hours per day (AOR: 3.763, 95% CI : 1.732, 8.176), the position of computer (AOR: 3.949, 95% CI: 1.308,11.921), using a computer without a break (AOR: 2.891, 95% CI: 1.397, 5.985), presence of glare on a computer (AOR: 3.864, 95% CI: 1.601,9.329), and older age (AOR=3.295, 95% CI: 1.245, 8.722) and (AOR: 4.828, 95% CI: 1.121, 20.797) were statistically associated with computer vision syndrome. Conclusion: In this study, the most common symptoms were blurred vision, eye irritation, and headache. Age, time spent on computer, the habit of taking a break, the level of computer and presence of glare were associated with the development of CVS.
计算机视觉综合征是主要的公共卫生问题之一。然而,研究生的患病率和相关因素尚不清楚,这使得提供和干预治疗更加困难。本研究旨在填补这一空白。方法:采用预先测试的结构化自填问卷,进行以机构为基础的横断面研究。数据输入流行病学信息第7版,导出到SPSS软件进行分析。p值<0.05认为有统计学意义。结果:共有359名学生参与本研究,回复率为96.38%。计算机视觉综合征患病率为84.4% (95% CI, 80.10-88.00)。每天使用电脑超过4.6小时(AOR: 3.763, 95% CI: 1.732, 8.176)、电脑位置(AOR: 3.949, 95% CI: 1.308,11.921)、不间断使用电脑(AOR: 2.891, 95% CI: 1.397, 5.985)、电脑上出现眩光(AOR: 3.864, 95% CI: 1.601,9.329)、年龄较大(AOR=3.295, 95% CI: 1.245, 8.722)和(AOR: 4.828, 95% CI: 1.121, 20.797)的学生与计算机视觉综合征有统计学关联。结论:在本研究中,最常见的症状是视力模糊、眼睛刺激和头痛。年龄、使用电脑的时间、休息的习惯、电脑的水平和眩光的存在与CVS的发展有关。

Introduction: Sickle cell disease is the most common genetic disease in the world. It is particularly prevalent in Africa south of the Sahara. In Cameroon. Several authors have described morphological changes from the macula to Optical Coherence Tomography-Spectral Domain (SD OCT) including the thinning of the predominant inner layers in the temporal area. Methodology: This is a prospective analytic study. It was conducted mainly at the specialized ophthalmology department of the Army Military Application and Reference Hospital of Yaounde (HMARAY) in Cameroon. Clinical ophthalmologic exam was done and biological parameters (rate of hemoglobin, electrophoretic quantification of S hemoglobin) registered from October 2016 to June 2017.We included: Any AS patient or Cameroonian SS patient who is 20 years of age or older; sickle cell patients AS or SS without intercurrent retinal pathology (strong myopia, diabetic retinopathy, vitreoretinal interface pathology). Results: In our study the average age is 31 years. There is a predominance of female versus male sex ratio H/F=0.56. 84% of eyes had retinal lesions suggestive of non-proliferative retinopathy in the retina. The solar black spots were the most found retinal lesions (66.66%). Lesions were more localized temporally. In the OCT measurement, 60% of the eyes showed a decreased retinal thickness SD with 53% concerning the temporal retina. An hemoglobin level between 7 and 10 g/dl was found in 40% of our patients, 24% has severe anemia (hemoglobin<7 g/dl). All our patients had a percentage of hemoglobin S greater than 80%. No decrease in visual acuity in our patients who had a decrease in retinal thickness at OCT SD. Conclusion: There is a thinning of the retinal layers in SS Cameroonian sickle cell patients in the temporal region of the macula. Patients with retinal thinning are asymptomatic with preserved visual acuity.
镰状细胞病是世界上最常见的遗传性疾病。它在撒哈拉以南的非洲特别普遍。在喀麦隆。一些作者描述了从黄斑到光学相干层析-光谱域(SD OCT)的形态学变化,包括颞区主要内层的变薄。方法:这是一项前瞻性分析研究。主要是在喀麦隆雅温得陆军军事应用和参考医院(HMARAY)专业眼科进行的。于2016年10月至2017年6月进行临床眼科检查,并登记血红蛋白率、S血红蛋白电泳定量等生物学参数。我们纳入:任何年龄在20岁或以上的AS患者或喀麦隆SS患者;无并发视网膜病变(重度近视、糖尿病视网膜病变、玻璃体视网膜界面病变)的镰状细胞患者。结果:本组患者平均年龄为31岁。男女性别比H/F=0.56为优势。84%的眼睛有视网膜病变提示视网膜非增殖性视网膜病变。视网膜病变以太阳黑斑最多(66.66%)。病变多局限于颞部。在OCT测量中,60%的眼睛显示视网膜厚度SD降低,其中53%的眼睛涉及颞视网膜。40%的患者血红蛋白水平在7 - 10g /dl之间,24%有严重贫血(血红蛋白< 7g /dl)。所有患者血红蛋白S百分比均大于80%。在我们的患者中,视网膜厚度在OCT SD上下降的患者视力没有下降。结论:SS喀麦隆镰状细胞患者黄斑颞区视网膜层变薄。视网膜变薄的患者无症状,视力保留。

Background: Acquired esotropia is a type of strabismus, which usually manifests around the age of 1-3 years. The aim of this study was to evaluate the outcomes of the surgical treatment of acquired partially accommodative and nonaccommodative esotropia in a group of esotropia patients in Albania. Methods: In total 52 patients aged 2-27 years, diagnosed with acquired partially or non-accommodative esotropia during the period January 2012-December 2017, participated in the study. Patients with complete accommodative esotropia were excluded. Ocular deviation and other parameters were assessed before and after operation and the results were compared to check whether differences were statistically significant. Results: Half (50%) of patients were 2-7 years of age (54% males). Retroposition was the most common surgical procedure, carried out in 50% of cases. Compared to before the intervention, after the intervention there was a significant universal reduction of ocular deviation in all patients at distance or near vision, with or without correction; a significant increase in the proportion of patients acquiring/retaining 3D vision and binocular vision, experiencing no suppression and no excyclotorsion. The most common complication related to surgical intervention was anesthesia-related vomiting (23.1%) and under correction or overcorrection (23.1% of cases). No significant changes were detected in the average visual acuity and the level of manifest and cycloplegic refraction. Conclusion: Surgical treatment for acquired esotropia is an effective procedure, based on significant reduction of mean ocular deviation and improved results of sensory tests after the intervention. Patients with post-surgical undercorrection and overcorrection need to be appropriately followed-up and treated.
背景:后天性内斜视是斜视的一种,通常表现在1-3岁左右。本研究的目的是评估阿尔巴尼亚一组内斜视患者获得性部分调节性和非调节性内斜视的手术治疗结果。方法:选取2012年1月至2017年12月期间诊断为获得性部分或非调节性内斜视的患者52例,年龄2-27岁。排除完全调节性内斜视患者。术前、术后评估眼偏度等参数,比较结果是否有统计学差异。结果:半数(50%)患者年龄在2-7岁,其中男性占54%。后卧是最常见的外科手术,占50%的病例。与干预前相比,干预后,无论是否矫正,所有患者的远视或近视的眼偏均显著降低;获得/保持三维视觉和双眼视觉,无压迫和无外旋的患者比例显著增加。与手术干预相关的最常见并发症是麻醉相关性呕吐(23.1%)和矫治不足或矫治过度(23.1%)。平均视力、明显屈光和睫状体麻痹性屈光均无明显变化。结论:手术治疗获得性内斜视是一种有效的治疗方法,干预后平均眼偏度明显降低,感觉检查结果明显改善。术后矫直不足和矫直过度的患者需要适当的随访和治疗。

Dry eye Disease (DED) effects up to 30% of the global population (2.25 Billion people) and this inflammatory condition of ocular surfaces has symptoms of visual disturbances, eye discomfort, tear film instability, etc. In the United States the average cost of treating this anomaly is over $6,500 with incidence rate of up to 20 million patients. This meeting will discuss three primary treatments of Cyclosporine 5%, Lifitegrast, and studies showing significance and differences between these treatments. A recent Systematic Review with meta-analysis was conducted on studies of Topical Cyclosporine 5% (Restasis®; Allergan, Inc., Irvine, CA). The 12 studies (mean 25 weeks) included 629 subjects receiving treatment of Restasis. The outcome measure shared between these studies was the Schirmer #1 test and the mean score reduction was 2.7 mm. A retrospective case/control study was conducted, measuring efficacy of Lifitegrast (Xiidra® Shire, Inc. Lexington, MA) versus other treatments in over 2,000 eyes. The mechanism of action is different than Cyclosporine because Lifitegrast reduces ocular inflammation as an integrin antagonist that blocks binding of ICAM-1 to LFA-1 on the T-cell surfaces. Testing in this investigation was accomplished with Schirmer’s tests, Corneal staining, and tear film Break Up Time (tBUT) in different sub populations. Even with different testing mechanisms, these Lifitegrast patients showed significant changes, particularly in short-term follow ups.
干眼病(DED)影响全球多达30%的人口(22.5亿人),这种眼表面炎症具有视力障碍、眼睛不适、泪膜不稳定等症状。在美国,治疗这种异常的平均费用超过6500美元,发病率高达2000万。本次会议将讨论5%环孢素和lifitgrast三种主要治疗方法,以及这些治疗方法之间的意义和差异的研究。最近的一项系统综述和荟萃分析对局部使用5%环孢素(Restasis®;艾尔建公司,欧文,加州)。12项研究(平均25周)包括629名接受Restasis治疗的受试者。这些研究共享的结果测量是Schirmer #1检验,平均评分降低2.7 mm。进行了一项回顾性病例/对照研究,测量lifitgrast (Xiidra®Shire, Inc.)的疗效。莱克星顿,马萨诸塞州)与其他治疗方法相比,超过2000只眼睛。其作用机制与环孢素不同,因为Lifitegrast作为一种整合素拮抗剂可阻断ICAM-1与LFA-1在t细胞表面的结合,从而减轻眼部炎症。本研究采用Schirmer试验、角膜染色和不同亚群的泪膜破裂时间(tBUT)来完成测试。即使使用不同的测试机制,这些Lifitegrast患者也显示出显著的变化,特别是在短期随访中。
