Background: Thalassemia major (TM) is an inherited anaemia caused by faulty haemoglobin synthesis. Reducing serum iron levels using iron chelating agents is an important step in the treatment of TM, and the effects on the eye of both the disease and these agents can be determined by regular eye examination.

Objectives: We evaluated macular and optic nerve vascular densities in children with TM and compared the results with healthy controls using optical coherence tomography angiography (OCTA).

Design: This is a prospective study.

Methods: A total of 30 children with TM and 30 healthy controls were included in the study. The area of the foveal avascular zone (FAZ) and the vascular densities (VD) of the optic nerve head (ONH), radial peripapillary capillary (RPC) and deep and superficial retinal vascular networks were measured using OCTA.

Results: A statistically significant decrease in VD was observed in the whole image and the parafovea, superior hemi, superior and inferior parts of the superficial capillary plexus and in the whole image and the superior regions of the deep capillary plexus in the TM patient group compared with the control group (p < 0.05). A significant decrease in VD was also observed in the whole image and the inside disc, peripapillary, nasal, inferonasal and temporal regions of the ONH and in the whole image and the inside disc, peripapillary and inferonasal regions of the RPC network in patients with TM (p < 0.05). A significant positive correlation was observed between both serum ferritin levels and deferasirox dosage, on one hand, and both the superficial (p = 0.023 and p = 0.002, respectively) and deep FAZs (p = 0.015 and p = 0.045, respectively), on the other hand. A negative correlation was also found between the deferasirox dosage and the VDs of the superficial (p = 0.010) and deep (p = 0.001) foveal plexuses.

Conclusion: Retinal VD and FAZ are affected in patients with TM. OCTA, which can noninvasively measure retinal VD in patients with TM, may be a useful tool for the early detection of retinal microvascular changes that may occur during the course of the disease.

背景:地中海贫血(TM)是一种由血红蛋白合成缺陷引起的遗传性贫血。使用铁螯合剂降低血清铁水平是治疗TM的重要步骤,可通过定期眼科检查确定疾病和这些药物对眼睛的影响。目的:我们利用光学相干断层扫描血管造影(OCTA)评估TM患儿的黄斑和视神经血管密度,并将结果与健康对照进行比较。设计:这是一项前瞻性研究。方法:选取30例TM患儿和30例健康对照进行研究。用OCTA测量视神经头(ONH)、桡骨乳头周围毛细血管(RPC)和视网膜深、浅血管网的血管密度(VD)、中央凹无血管区(FAZ)面积。结果:与对照组相比,TM患者组在全像及浅毛细血管丛中央旁、上半、上、下部分、深毛细血管丛全像及上区VD均有统计学意义的降低(p = 0.023、p = 0.002),在深faz区VD均有统计学意义的降低(p = 0.015、p = 0.045)。去铁铁剂量与浅窝神经丛(p = 0.010)和深窝神经丛(p = 0.001)的VDs呈负相关。结论:TM患者视网膜VD和FAZ均受影响。OCTA可以无创地测量TM患者的视网膜VD,可能是早期发现疾病过程中可能发生的视网膜微血管变化的有用工具。

Background: Ocular biometry and anterior segment evaluations are important to determine ocular development and pathological changes, especially in thalassemia patients in Mediterranean countries such as Turkey.

Objectives: The objectives of this study were to compare ocular biometry and anterior segment parameters in children with thalassemia major and healthy controls and to examine the relationship between ferritin levels, anthropometric measurements, and ocular parameters.

Design: This is a prospective case-control study.

Methods: The height, weight, body mass index, and occipitofrontal circumference values of the participants were recorded. Anterior and vitreous chamber depth, lens thickness, axial length, central corneal thickness, anterior chamber volume, iridocorneal angle, pupil diameter, and mean keratometry were measured. Measurements were compared between patients and healthy children, and between patients with ferritin levels above and below 1000 ng/mL.

Results: This study included 40 patients and 45 controls. Height, weight, and body mass index were significantly lower while ferritin level and occipitofrontal circumference were significantly higher in patients compared with the controls (p < 0.001 for all). There were no statistically significant differences in the other ocular parameters (p > 0.05). In comparisons between patients with ferritin levels below (n = 15) and above 1000 ng/mL (n = 25), there were no significant differences in age, height, weight, body mass index, occipitofrontal circumference, or ocular parameters (p > 0.05). Occipitofrontal circumference and mean keratometry value were positively correlated in patients with ferritin levels below 1000 ng/mL (r = 0.573, p = 0.025), while body mass index was negatively correlated with pupil diameter in patients with ferritin levels above 1000 ng/mL (r = -0.469, p = 0.018).

Conclusion: Children with thalassemia showed significant growth retardation and large occipitofrontal circumference but did not differ from controls in terms of biometrics and anterior segment morphology. Our results demonstrated a positive correlation between the occipitofrontal circumference and mean keratometry value in children with ferritin levels below 1000 ng/mL and a negative correlation between body mass index and pupil diameter in children with ferritin levels above 1000 ng/mL.

背景:眼部生物测量和前节评估对于确定眼部发育和病理变化非常重要,特别是在地中海国家如土耳其的地中海贫血患者中。目的:本研究的目的是比较重度地中海贫血儿童和健康对照者的眼部生物测量和前段参数,并检查铁蛋白水平、人体测量和眼部参数之间的关系。设计:这是一项前瞻性病例对照研究。方法:记录受试者的身高、体重、身体质量指数和枕额围值。测量前房和玻璃体房深度、晶状体厚度、轴向长度、角膜中央厚度、前房体积、虹膜角膜角、瞳孔直径和平均角膜度数。比较患者与健康儿童之间的测量值,以及铁蛋白水平高于和低于1000 ng/mL的患者之间的测量值。结果:本研究纳入40例患者和45例对照组。与对照组相比,患者身高、体重、体质指数明显降低,铁蛋白水平和枕额围明显升高(p p > 0.05)。在铁蛋白水平低于(n = 15)和高于1000 ng/mL (n = 25)的患者中,年龄、身高、体重、体重指数、枕额围、眼部参数比较,差异均无统计学意义(p > 0.05)。铁蛋白水平低于1000 ng/mL的患者枕额围与平均角膜测量值呈正相关(r = 0.573, p = 0.025),高于1000 ng/mL的患者体重指数与瞳孔直径呈负相关(r = -0.469, p = 0.018)。结论:地中海贫血患儿表现出明显的生长迟缓和较大的枕额围,但在生物特征和前节形态方面与对照组没有差异。我们的研究结果表明,在铁蛋白水平低于1000 ng/mL的儿童中,枕额围与平均角膜测量值呈正相关,在铁蛋白水平高于1000 ng/mL的儿童中,体重指数与瞳孔直径呈负相关。

Three-dimensional (3D) printing uses a process of adding material in a layer-by-layer fashion to form the end product. This technology is advancing rapidly and is being increasingly utilized in the medical field as it becomes more accessible and cost-effective. It has an increasingly important role in ophthalmology and eyecare as its current and potential applications are extensive and slowly evolving. Three-dimensional printing represents an important method of manufacturing customized products such as orbital implants, ocular prostheses, ophthalmic models, surgical instruments, spectacles and other gadgets. Surgical planning, simulation, training and teaching have all benefitted from this technology. Advances in bioprinting seem to be the future direction of 3D printing with possibilities of printing out viable ocular tissues such as corneas and retinas in the future. It is expected that more ophthalmologists and other clinicians will use this technology in the near future.

三维(3D)打印采用逐层添加材料的方式形成最终产品。这项技术发展迅速,在医疗领域的应用也越来越广泛,因为它越来越容易获得,成本效益也越来越高。它在眼科和眼保健领域的作用日益重要,因为其当前和潜在的应用领域非常广泛,而且在不断发展。三维打印是制造眼眶植入物、眼科假体、眼科模型、手术器械、眼镜和其他小工具等定制产品的重要方法。手术规划、模拟、培训和教学都受益于这项技术。生物打印技术的进步似乎是 3D 打印技术的未来发展方向,未来有可能打印出角膜和视网膜等可存活的眼部组织。预计在不久的将来,会有更多的眼科医生和其他临床医生使用这项技术。

The retinal world has been revolutionized by optical coherence tomography (OCT) and anti-vascular endothelial growth factor (VEGF) therapy. The numbers of intravitreal injections are on a constant rise and management in neovascular age-related macular degeneration (nAMD) is mainly driven by the qualitative assessment of macular fluid as detected on OCT scans. The presence of macular fluid, particularly subretinal fluid (SRF) and intraretinal fluid (IRF), has been used to trigger re-treatments in clinical trials and the real world. However, large discrepancies can be found between the evaluations of different readers or experts and especially small amounts of macular fluid might be missed during this process. Pixel-wise detection of macular fluid uses an entire OCT volume to calculate exact volumes of retinal fluid. While manual annotations of such pixel-wise fluid detection are unfeasible in a clinical setting, artificial intelligence (AI) is able to overcome this hurdle by providing real-time results of macular fluid in different retinal compartments. Quantitative fluid assessments have been used for various post hoc analyses of randomized controlled trials, providing novel insights into anti-VEGF treatment regimens. Nonetheless, the application of AI-algorithms in a prospective patient care setting is still limited. In this review, we discuss the use of quantitative fluid assessment in nAMD during anti-VEGF therapy and provide an outlook to novel forms of patient care with the support of AI quantifications.
光学相干断层扫描(OCT)和抗血管内皮生长因子(VEGF)治疗已经彻底改变了视网膜世界。玻璃体内注射的数量在不断增加,新血管性年龄相关性黄斑变性(nAMD)的治疗主要是由OCT扫描检测到的黄斑液的定性评估驱动的。黄斑液的存在,特别是视网膜下液(SRF)和视网膜内液(IRF),已被用于触发临床试验和现实世界中的再治疗。然而,不同的读者或专家的评价之间可能存在很大的差异,特别是在这个过程中可能会遗漏少量的黄斑液。逐像素检测黄斑液使用整个OCT体积来计算视网膜液的精确体积。虽然这种逐像素液体检测的手动注释在临床环境中是不可行的,但人工智能(AI)能够通过提供不同视网膜隔室中黄斑液体的实时结果来克服这一障碍。定量体液评估已用于随机对照试验的各种事后分析,为抗vegf治疗方案提供了新的见解。尽管如此,人工智能算法在未来患者护理环境中的应用仍然有限。在这篇综述中,我们讨论了在抗vegf治疗期间定量液体评估在nAMD中的应用,并展望了人工智能定量支持下的新型患者护理形式。

Treatment results of nondamaging retinal laser therapy in diabetic macular edema. 无损伤视网膜激光疗法对糖尿病黄斑水肿的治疗效果。
IF 2.3 Q2 OPHTHALMOLOGY Pub Date : 2022-01-14 eCollection Date: 2022-01-01 DOI: 10.1177/25158414211063284

Background: Subthreshold nondamaging retinal laser therapy (NRT) provides a greater safety profile than conventional laser methods, but more data is needed on the efficacy and safety of subthreshold NRT in diabetic macular edema.

Purpose: To evaluate the efficacy and safety of NRT for the treatment of clinically significant macular edema (CSME) that is partially responsive or resistant to intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment.

Methods: This was a retrospective case series study. Fifty eyes of 38 diabetic patients with CSME previously treated with at least 6-monthly intravitreal bevacizumab injections with/without intravitreal Ozurdex therapy were evaluated. The patients received 577-nm yellow wavelength laser therapy with PASCAL laser system (Topcon Medical Laser Systems, Santa Clara, CA, USA). Best-corrected visual acuity (BCVA) and central subfield thickness (CST) were evaluated before and 1, 3, 6, 12 and 24 months after laser treatment.

Results: Baseline mean CST was 368.06 ± 86.9 µm. The mean CST values at the 1-, 3-, 6-, 12-, and 24-month visits were 336.93 ± 79.8, 352.40 ± 113.5, 336.36 ± 109.3, 325.10 ± 104 µm, and 310.08 ± 84.7 µm, respectively. The mean CST decreased significantly at the first (p = 0.002) and second year visits (p < 0.001) when compared with pretreatment values. Although visual acuity was improved at the first year compared with baseline, this difference was not statistically significant (p = 0.03). There was no significant difference in visual acuities between pretreatment and posttreatment visits. During 24-month follow-up, while 37 eyes were treated with [mean: 5.7 ± 3.4 (1-14)] intravitreal anti-VEGF injections, 3 eyes were administered single-dose intravitreal steroids. Additional intravitreal injections were not required in 10 (20%) eyes.

Conclusion: NRT is effective by itself or in combination with anti-VEGF agents in diabetic macular edema that is partially responsive or resistant to previous intravitreal injections. T role in treating this disorder should be assessed in more detail with prospective controlled studies.

背景:目的:评估阈下无损伤视网膜激光疗法(NRT)治疗对玻璃体内抗血管内皮生长因子(anti-VEGF)治疗部分反应或耐药的临床重大黄斑水肿(CSME)的疗效和安全性:这是一项回顾性病例系列研究。方法:这是一项回顾性病例系列研究。对 38 名糖尿病 CSME 患者中的 50 只眼睛进行了评估,这些患者曾接受过至少 6 个月一次的玻璃体内贝伐单抗注射和/或玻璃体内 Ozurdex 治疗。患者使用 PASCAL 激光系统(Topcon Medical Laser Systems, Santa Clara, CA, USA)接受 577 纳米黄色波长激光治疗。对激光治疗前、治疗后 1、3、6、12 和 24 个月的最佳矫正视力(BCVA)和中央子场厚度(CST)进行了评估:基线平均 CST 值为 368.06 ± 86.9 µm。1、3、6、12 和 24 个月时的平均 CST 值分别为 336.93 ± 79.8、352.40 ± 113.5、336.36 ± 109.3、325.10 ± 104 µm 和 310.08 ± 84.7 µm。CST 平均值在第一年(P = 0.002)和第二年(P = 0.03)时明显下降。治疗前和治疗后的视力没有明显差异。在 24 个月的随访期间,37 只眼睛接受了[平均:5.7 ± 3.4 (1-14)]次玻璃体内抗 VEGF 注射治疗,3 只眼睛接受了单剂量玻璃体内类固醇治疗。有 10 眼(20%)无需进行额外的玻璃体内注射:结论:NRT 本身或与抗血管内皮生长因子药物联合使用,对之前玻璃体内注射有部分反应或耐药的糖尿病性黄斑水肿有效。应通过前瞻性对照研究更详细地评估 NRT 在治疗这种疾病中的作用。

The mean CST values at the 1-, 3-, 6-, 12-, and 24-month visits were 336.93 ± 79.8, 352.40 ± 113.5, 336.36 ± 109.3, 325.10 ± 104 µm, and 310.08 ± 84.7 µm, respectively. The mean CST decreased significantly at the first (<i>p</i> = 0.002) and second year visits (<i>p</i> < 0.001) when compared with pretreatment values. Although visual acuity was improved at the first year compared with baseline, this difference was not statistically significant (<i>p</i> = 0.03). There was no significant difference in visual acuities between pretreatment and posttreatment visits. During 24-month follow-up, while 37 eyes were treated with [mean: 5.7 ± 3.4 (1-14)] intravitreal anti-VEGF injections, 3 eyes were administered single-dose intravitreal steroids. Additional intravitreal injections were not required in 10 (20%) eyes.</p><p><strong>Conclusion: </strong>NRT is effective by itself or in combination with anti-VEGF agents in diabetic macular edema that is partially responsive or resistant to previous intravitreal injections.

Background: Spontaneous vitreous hemorrhage is one of the common causes of ocular emergency. There are very few prospective studies on the clinical profile and surgical outcomes for patients with dense vitreous hemorrhage caused by non-diabetic and non-traumatic till date to our knowledge. Objectives: This study was conducted to better understand the etiologies, clinical profile, surgical outcome, and visual prognosis following pars plana vitrectomy for dense vitreous hemorrhage in adults with non-traumatic and non-diabetic retinopathy. Design: This was a prospective interventional study. Methods: This study was conducted in Mechi Eye Hospital (Birtamod, Nepal) from October 2018 to September 2019. All consecutive cases, 46 eyes of 46 patients, with vitreous hemorrhage that underwent vitrectomy were included in our study. There were 14 (30.4%) female and 32 (69.6%) male patients, and the average age at presentation was 43.74 ± 16.19 (17–84) years. The success rate of surgery in terms of visual outcome was evaluated. Results: The most common cause of vitreous hemorrhage was retinal vasculitis with fibrovascular changes and vascular sheathing 19 (41%). The indication of vitrectomy on patient demand was 20 (43.5%). Success rate of surgery in terms of visual outcome (functional outcome) was defined as final visual acuity of >6/60 which was 86.9%. Conclusion: The most common cause of spontaneous vitreous hemorrhage in our study was retinal vasculitis with fibrovascular changes and vascular sheathing. Vitrectomy has a good surgical outcome for spontaneous vitreous hemorrhage in terms of visual outcome (functional outcome) unless guarded by other factors like chorioretinal atrophy followed by optic atrophy and epiretinal membrane.
背景:自发性玻璃体出血是眼部急症的常见原因之一。据我们所知,迄今为止关于非糖尿病和非创伤性玻璃体致密出血患者的临床特征和手术结果的前瞻性研究很少。目的:本研究旨在更好地了解非外伤性和非糖尿病性视网膜病变的成人密集玻璃体出血的玻璃体平面肌切除术后的病因、临床特点、手术结果和视力预后。设计:这是一项前瞻性干预性研究。方法:本研究于2018年10月至2019年9月在尼泊尔比塔莫德梅奇眼科医院进行。我们的研究包括所有连续的病例,46例患者的46只眼,因玻璃体出血而行玻璃体切除术。女性14例(30.4%),男性32例(69.6%),平均发病年龄43.74±16.19(17-84)岁。从视觉效果方面评估手术成功率。结果:玻璃体出血最常见的原因是视网膜血管炎伴纤维血管改变和血管鞘改变19例(41%)。应患者要求行玻璃体切除术的患者占43.5%。手术在视力(功能)方面的成功率定义为最终视力为bb0 6/60,为86.9%。结论:自发性玻璃体出血最常见的原因是视网膜血管炎伴纤维血管改变和血管鞘。对于自发性玻璃体出血,玻璃体切除术在视力(功能)方面具有良好的手术效果,除非有其他因素的保护,如绒毛膜视网膜萎缩继发视神经萎缩和视网膜前膜。

COVID-19 is a disease caused by a SARS-CoV-2 viral infection, a disease that was first detected in December 2019 in Wuhan, Hubei Province, China. COVID-19, formerly known as 2019 Novel Coronavirus (2019-nCoV) respiratory disease, was officially named COVID-19 by the World Health Organization (WHO) in February 2020. By 25 May 2021, there were 33,579,116 confirmed cases with 599,109 COVID-19 deaths worldwide. The purpose of this review article is to provide an update on what is currently known about COVID-19 ocular symptoms in adults, the elderly, and children in the literature. Finally, this article will review the eye protection precautions that should be implemented in our clinics. To assess the current literature, PubMed was searched from December 2019 to 25 May 2021. Randomized trials, observational studies, case series or case reports, letters of research, and letters to editors were selected for confirmed cases of COVID-19. According to current scientific literature since the outbreak in December 2019, 205 articles have been published. Conjunctivitis, conjunctival hyperemia, and chemosis have been reported in adults with COVID-19. There have been few studies on children and elderly patients, and further research in these age groups is needed. Finally, wearing eye protection when seeing patients on a daily basis during the pandemic is essential.
COVID-19是一种由SARS-CoV-2病毒感染引起的疾病,这种疾病于2019年12月在中国湖北省武汉市首次发现。2019冠状病毒病,原名2019新型冠状病毒(2019- ncov)呼吸道疾病,于2020年2月被世界卫生组织正式命名为COVID-19。截至2021年5月25日,全球共有33,579,116例确诊病例,599,109例死亡。这篇综述文章的目的是提供目前已知的关于成人、老年人和儿童的COVID-19眼部症状的最新文献。最后,本文将对临床应注意的护眼事项进行综述。为了评估当前文献,检索了2019年12月至2021年5月25日的PubMed。对COVID-19确诊病例选择随机试验、观察性研究、病例系列或病例报告、研究信函和给编辑的信函。根据目前的科学文献,自2019年12月疫情爆发以来,已发表205篇文章。结膜炎、结膜充血和化脓在成人COVID-19中有报道。关于儿童和老年患者的研究很少,需要对这些年龄组进行进一步的研究。最后,在大流行期间,每天看病人时戴上护目镜是必不可少的。

Biological drugs, termed biologics, are medications that contain or are derived from a living organism (human, animal, or microorganism). With new biological agents being approved by the Food and Drug Administration (FDA) every year, clinicians need to know potential ocular adverse effects that are associated with these drugs. This review provides an overview of ocular adverse effects of biological medications used to treat both ophthalmic and non-ophthalmic diseases. We searched PubMed for relevant case reports, case series, reviews, and clinical trials reporting ocular adverse effects caused by biologics. This review was conducted in June 2021 and investigated the drugs listed in the most updated (April 2021) FDA Purple Book Database of Licensed Biological Products. This review focuses on monoclonal antibodies, interleukins, and receptor fusion proteins. We explore ocular side effects of 33 biological drugs, stating whether they are frequent, common, or rare.

Background: Laser peripheral iridotomy (LPI) is the current standard of care for primary angle-closure glaucoma. The existing literature lacks evidence regarding the effects of LPI on contrast sensitivity (CS) after the procedure.

Objective: This study evaluates central and peripheral CS in patients undergoing LPI using the computer-based, Spaeth/Richman Contrast Sensitivity (SPARCS) test.

Methods: We performed a pilot, prospective, interventional cohort study including 30 patients of primary angle-closure suspect (PACS) or primary angle closure (PAC) in both eyes. LPI was performed after a detailed history and clinical examination using standard procedure in all eyes. Intraocular pressure (IOP) and CS testing using SPARCS was performed before, 2 weeks and 3 months after LPI.

Results: Data analyses revealed female predominance (66.67%, 20/30); the mean age of enrolled patients was 49.93 ± 10.43 years, and presenting acuity was 0.02 ± 0.06 (Log of Minimum Angle of Resolution [LogMAR]). The mean vertical cup-to-disc ratio (VCDR), mean deviation (MD in dB) and pattern standard deviation (PSD in dB) were 0.34 ± 0.09, -2.36 ± 1.72 and 2.34 ± 0.81, respectively. There was a statistically significant decrease between the pre- (15.17 ± 3.83 mmHg) and 2 weeks post-LPI (11.70 ± 1.53 mmHg) IOP (p < 0.001). However, CS in the pre- (73.47 ± 9.88) and 3 months post-LPI (75.20 ± 11.98) SPARCS scores did not reveal any statistical difference. The group-wise analysis showed a similar trend between PAC and PACS patients.

Conclusion: LPI does not affect central as well as peripheral CS assessment in patients with the primary angle-closure disease.

背景:激光周围虹膜切开术(LPI)是目前治疗原发性闭角型青光眼的标准方法。现有文献缺乏关于LPI对术后对比敏感度(CS)影响的证据。目的:本研究使用基于计算机的Spaeth/Richman对比灵敏度(SPARCS)测试评估LPI患者的中枢和外周CS。方法:我们对30例双眼原发性闭角疑似(PACS)或原发性闭角(PAC)患者进行了一项前瞻性、干预性队列研究。在详细的病史和临床检查后,采用全眼标准程序进行LPI。分别于LPI术前、术后2周和3个月采用SPARCS法测定眼压(IOP)和CS。结果:资料分析显示女性优势(66.67%,20/30);入组患者的平均年龄为49.93±10.43岁,视力为0.02±0.06(最小分辨角对数[LogMAR])。平均垂直杯盘比(VCDR)、平均偏差(MD, dB)和模式标准差(PSD, dB)分别为0.34±0.09、-2.36±1.72和2.34±0.81。LPI前(15.17±3.83 mmHg)和LPI后2周(11.70±1.53 mmHg) IOP (p)之间有统计学意义的降低。结论:LPI不影响原发性闭角症患者的中枢和外周CS评估。

Background: Anti-vascular endothelial growth factor intravitreal injections (IVIs) have proved to be a boon for patients suffering from several retinal pathologies. They are one of the most commonly performed procedures in ophthalmology. A perioperative rise in blood pressure (BP) has been noted during cataract surgery. Objectives: To evaluate the perioperative BP changes during IVI, and the associated risk factors. Design: Cross-sectional observational study Methods: The patients undergoing IVI from May 2019 to August 2019 were evaluated. All the patients underwent BP measurement before, during, and 1 h after the IVI. The correlation between the demographics and, the systemic comorbidities of the patients, and the ocular condition for which IVI was given was evaluated. Results: The study included 302 patients (mean age of 59.9 ± 10.7 years). The mean increase in systolic BP (SBP) and diastolic BP (DBP) at the time of injection was 25.7 ± 21.0 and 1.3 ± 13.4 mmHg, respectively. A ⩾ 10, ⩾ 20, ⩾ 30 mmHg increase in SBP at the time of injection was seen in 83.8% (n = 253), 69.5% (n = 210) and 49.0% (n = 148) patients, respectively. Forty-one (13.6%) patients developed intra-procedural hypertensive urgency, out of which six patients (14.6%) did not recover even after 1 h of the procedure. None of the patients experienced any cardiovascular events. The univariate and multivariate linear regression analyses showed that the change in intra-procedural SBP correlated positively with the age of the patient and negatively with the baseline SBP. Conclusion: There is a significant rise of SBP at the time of IVI, especially in patients with advanced age and high baseline SBP. Some of the patients can experience hypertensive urgency at the time of injection and may take more than 1 h to recover. The patients receiving IVI should undergo a detailed physician evaluation before the procedure.
背景:抗血管内皮生长因子玻璃体内注射(IVI)已被证明对患有多种视网膜疾病的患者是一种福音。它们是眼科最常见的手术之一。白内障手术期间,围手术期血压升高。目的:评价IVI围手术期血压变化及其相关危险因素。设计:横断面观察性研究方法:对2019年5月至2019年8月接受IVI的患者进行评估。所有患者在IVI之前、期间和之后1小时都进行了血压测量。评估了人口统计学和患者的系统性合并症以及给予IVI的眼部状况之间的相关性。结果:该研究包括302名患者(平均年龄59.9岁) ± 10.7年)。注射时收缩压(SBP)和舒张压(DBP)的平均增加为25.7 ± 21.0和1.3 ± 13.4毫米汞柱。A. ⩾ 10, ⩾ 20, ⩾ 注射时收缩压增加30mmHg的患者占83.8%(n = 253)、69.5%(n = 210)和49.0%(n = 148)患者。四十一名(13.6%)患者在手术中出现高血压紧急情况,其中六名患者(14.6%)即使在手术1小时后也没有恢复。没有一名患者出现任何心血管事件。单变量和多变量线性回归分析显示,术中SBP的变化与患者年龄呈正相关,与基线SBP呈负相关。结论:IVI时SBP显著升高,尤其是在高龄和高基线SBP的患者中。一些患者在注射时会出现高血压紧迫感,可能需要1小时以上才能恢复。接受IVI的患者应在手术前接受详细的医生评估。

The patients receiving IVI should undergo a detailed physician evaluation before the procedure.","PeriodicalId":23054,"journal":{"name":"Therapeutic Advances in Ophthalmology","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45959238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
