:343-346
 
目的:分析玻璃体腔注射术后眼内炎的发生并总结原因,旨在进一步提高手术安全性。方法:回顾性分析中国人民解放军总医院第六医学中心2010年9月至2019年11月行玻璃体腔注射术的421例患者(973眼)的术后1 d、1周、1个月的随访资料。归纳注射药物种类、注射病因、患者全身病史,总结术后眼内炎的发生及治疗情况。结果:玻璃体腔注射术安全性高,但严重并发症眼内炎(0.41%)仍偶有发生。4例眼内炎患者中2例为Irvine-Gass综合征患者行曲安奈德玻璃体腔注射后,1例为视网膜中央静脉阻塞患者行曲安奈德玻璃体腔注射后,1例为中心性渗出性视网膜脉络膜病变患者行雷珠单抗玻璃体腔注射后。其中曲安奈德引起的眼内炎(1.99%)明显高于抗血管内皮生长因子(vascular endothelial growth factor,VEGF)药物引起的眼内炎(0.12%)。结论:严格按照操作指南操作,当针对高血压老年群体尤其是Irvine-Gass综合征患者玻璃体腔注射曲安奈德时尤其防范眼内炎的发生。
Objective: To analyze the incidence and causes of endophthalmitis after intravitreal injection and to further improve the safety of the surgery. Methods: The follow-up data of 973 eyes of 421 patients who received intravitreal injection in our hospital in the past 9 years at 1 day, 1 week and 1 month were retrospectively analyzed.The types of injected drugs, the cause of injection and systemic history were summarized, and the occurrence and treatment of postoperative endophthalmitis were summarized. Results: The intravitreal injections were safe.However, the severe complication of endophthalmitis (0.41%) occurred occasionally. Among these 4 patients with endophthalmitis, 2 patients were intravitreal injected triamcinolone acetonide because of Irvine-Gass syndrome;1 patient accepted intravitreal injection by Ranibizumab because of central retinal vein occlusion; 1 patient accepted intravitreal injection by Ranibizumab because of central exudative chorioretinopathy. The incidence of endophthalmitis (1.99%) after intravitreal injection of triamcinolone acetonide was higher than that of anti-vascular endothelial growth factor (VEGF) agents (0.12%). Conclusion: The clinical operating guideline of intravitreal injection should be followed strictly. Furthermore, the elderly people with hypertension diagnosed of Irvine-Gass syndrome have a higher risk of endophthalmitis after intravitreal injection of triamcinolone acetonide than others and should be paid more important attention.

玻璃体腔注射抗VEGF药物治疗湿性年龄相关性黄斑变性的5年回顾性研究

Intravitreal injection of anti-VEGF agents in wet age-related macular degeneration: a 5-year retrospective study

:537-543
 
目的:调查抗VEGF药物治疗湿性年龄相关性黄斑变性(wet age-related macular degeneration, wAMD)5年的疗效。方法:2011年至2021年于北京医院眼科诊断为wAMD的患者共84人103只眼进行回顾性分析。抗VEGF治疗采用3+PRN方案。观察5年来的最佳矫正视力(best-corrected visual acuity,BCVA)、玻璃体腔注射次数、随访次数和病灶的解剖学变化。结果:治疗5年后平均BCVA为38.1个字母,与基线相比下降9.4个字母,差异有统计学意义(P<0.001)。23.3%的患眼5年后可维持初始视力。5年内平均注射次数为13.8次,第1年注射次数最多,平均为4.3次。5年内平均随访次数为24.3次,仅有34.0%的患眼可遵循每次随访间隔≤3个月。5年后有68.0%的患眼出现纤维瘢痕,27.2%的患眼出现地图样萎缩,69.0%(71/103)的患眼存在持续的色素上皮脱离(pigment epithelial detachment,PED)。年龄、基线BCVA、是否初始治疗、随访年限、注射次数、中心视网膜厚度 (central retina thickness,CRT)、地图样萎缩等对BCVA有显著影响。结论:多数患者在抗VEGF治疗1年内可维持视力,但5年以上维持效果不佳。早期诊治、提高注射频率,可能是未来改善预后的研究方向。
Objective:To investigate the efficacy of anti-VEGF injection in the treatment of wet age-related macular degeneration (wAMD) for 5 years. Methods: A total of 84 patients (103 eyes) wAMD diagnosed in Department of Ophthalmology in Beijing Hospital from 2011 to 2021 were analyzed retrospectively. 3 + PRN regimen was applied for anti-VEGF treatment. The changes of best corrected visual acuity (BCVA), the number of intravitreal injections and the number of follow-up visits, and the anatomical changes of the lesions in the past 5 years were collected. Results: The average BCVA after 5 years was 38.1 letters, indicating a decrease of 9.4 letters comparing to baseline, which was statistically significant (P<0.001). 23.3% of the eyes could maintain the baseline BCVA after 5 years. The average injection times within 5 years was 13.8, and the injection was concentrated in the first year, with an average of 4.3. The average number of follow-up visits within 5 years was 24.3, and only 34.0% of the affected eyes could keep the follow-up interval ≤3 months. After 5 years, 68.0% of the eyes developed fibrous scar, 27.2% developed geographic atrophy, and 69.0% (71/103) had consistent pigment epithelial detachment. Factors significantly affect BCVA include: age, baseline BCVA, initial treatment, follow-up time, injection times, central retinal thickness, geographic atrophy and so on. Conclusion: Most patients can maintain vision within the first year after anti-VEGF treatment, but the efficacy is poor for more than 5 years. Early diagnosis and treatment, and increased injection frequency may be the research direction for improving prognosis in the future.

息肉状脉络膜血管病变继发玻璃体积血的治疗及预后

Treatment modalities and visual prognosis of polypoidal choroidal vasculopathy with breakthrough vitreous hemorrhage

:658-664
 
息肉状脉络膜血管病变(polypoidal choroidal vasculopathy,PCV)是亚洲人中常见的眼底致盲性疾病,当PCV合并视网膜下出血或玻璃体积血(vitreous hemorrhage,VH)时,患者视力骤然下降,视力预后差异大。但目前聚焦于PCV合并VH的相关文献较少,因此研究和阐明PCV继发VH的治疗方法及预后具有重要的临床意义。目前临床上常选择手术干预,玻璃体切除术(pars plana vitrectomy,PPV)是临床上最常选择的一种术式。其他治疗方式包括玻璃体内注射抗血管内皮生长因子(vascular endothelial growth factor,VEGF)、眼内气体或硅油填充、眼内注射组织纤溶酶原激活剂(tissue plasminogen activator,tPA)和光动力疗法(photodynamic therapy,PDT)。PCV合并VH患者的视力预后决定因素是黄斑视功能的保留程度,也与年龄、术前视力、PCV病变部位、视网膜下出血量、视网膜脱离范围、基线黄斑中心厚度(central macular thickness,CMT)、是否出现术后并发症以及是否形成视网膜瘢痕等因素相关,目前也有研究发现视力预后与单核苷酸多态性(single nucleotide polymorphisms,SNP)相关。本文就PCV继发VH的临床特点、治疗及预后进行综述。
Polypoid choroidal vasculopathy (PCV) is a common fundus blinding disease in Asians. When PCV is associated with subretinal hemorrhage or vitreous hemorrhage (VH), patient's visual acuity decreases suddenly and the visual prognosis varies greatly. There are few relevant literatures focusing on VH secondary to PCV, so it is of great clinical significance to study and clarify the treatment methods and prognosis of VH secondary to PCV. At present, surgical intervention is often selected in clinical practice. Vitrectomy is the most commonly selected surgical procedure in clinical practice. The other treatment modalities include intravitreal injection of antivascular endothelial growth factor (VEGF), intraocular gas or silicone oil filling, intraocular injection of tissue plasminogen activator (tPA) and photodynamic therapy. The prognostic determinant of visual acuity in PCV
patients with VH is the degree of preservation of macular visual function. The prognostic is also related to age, preoperative visual acuity, PCV lesion location, amount of subretinal hemorrhage, extent of retinal detachment, baseline central macular thickness (CMT), postoperative complications and retinal scars. Recent studies also find that the prognosis of visual acuity is related to single nucleotide polymorphisms. This article reviews the clinical characteristics, treatment and visual prognosis of PCV associated with VH.

Objective: The aim of this study was to compare the efficacy and safety of dexmedetomidine versus midazolam for the monitored anesthesia care (MAC) management of patients undergoing vitreoretinal surgery. Methods: Forty patients undergoing selective vitreoretinal surgery were double-blind and randomly dividedinto midazolam group (group M) and dexmedetomidine group (group D), each group had 20 patients. Patients in both groups were anesthetized with posterior bulbous nerve block. Bispectral index (BIS) monitor was connected and the BIS value was maintained between 70 and 90. The mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), oxygen saturation (SpO2), Ramsay sedation score, numerical rating scale (NRS), surgeon’s and patient’s anesthesia effect score and adverse reactions were recorded during anesthesia and recovery period. Results: Compared with the data of pre-anesthesia, there were statistical differences of the decrease of HR and MAP in group D within the 10 minutes after medication (P<0.05), and the decrease of HR in group D was greater than that in group M (P<0.05). The NRS pain score in group D was significantly lower than that in group M with statistical significance (P<0.001) during the operation and resuscitation, while there was no significant difference in Ramsay sedation score between the two groups during the operation and resuscitation (P>0.05). In terms of adverse reactions to anesthesia, the incidence of spontaneous movement and oxycodone utilization in group D were significantly lower than those in group M (P<0.05). The anesthesia effect scores of surgeons and patients in group D were significantly higher than those in group M (all P<0.001). Conclusion: Dexmedetomidine has better analgesic effect and less adverse reactions than midazolam in vitreoretinal surgery.

目的:以光学相干断层扫描血管成像(optical coherence tomography angiography,OCTA)观察视网膜分支静脉阻塞(branch retinal vein occlusion,BRVO)抗血管内皮生长因子(vascular endothelial growth factor,VEGF)治疗前后的变化。方法:回顾性收集从2017年1月至2018年1 2月在汕头国际眼科中心的确诊为BRVO合并黄斑水肿的患者共3 1例3 2眼。患眼行玻璃体腔注射抗VEGF药物治疗,记录治疗前和治疗后1个月的最佳矫正视力(best corrected visual acuity,BCVA),OCTA检查视网膜黄斑中心凹厚度(foveal macular thickness,FMT)、黄斑区血流密度。比较治疗前后各指标的变化。结果:治疗后BCVA较治疗前显著提高,差异有统计学意义(P<0.001);FMT[(242.13±86.02) μm]较治疗前[(521.44±190.27) μm]明显下降,差异有统计学 意义(P<0.001);中心凹浅层血流密度[(18.44±4.98)%]及中心凹旁浅层血流密度[(44.83±3.19)%]均较治疗前[(25.46±9.21)%,(46.06±5.25)%]相比明显下降,差异有统计学意义(P <0.001)。结论:玻璃体腔注射抗VEGF治疗BRVO合并黄斑水肿效果显著;OCTA能有效评价抗VEGF治疗BRVO合并黄斑水肿的临床疗效。
Objective: To evaluate the efficacy in patients with macular edema due to branch retinal vein occlusion (BRVO) treated with intravitreal anti-VEGF drug. Methods: In this retrospective study, 32 eyes of 31 patients with BRVO combined with macular edema at Joint Shantou international eye center of Shantou University and TheChinese University of Hong Kong during January 2017 to December 2018 were enrolled in this study. All the affected eyes received intravitreal anti-VEGF drug injections. BCVA (best corrective visual acuity) and optical coherence tomography angiography (OCTA) were performed before and one month after intravitreal anti-VEGF drug injections. Foveal macular thickness (FMT), macular blood flow density was measured in all eyes and compared. Results: The BCVA before therapy was (0.77±0.46) LogMAR and increased to (0.46±0.30) LogMAR in one month after therapy, which showed a statistical difference (P<0.001). The FMT, foveal superficial vascular plexus flow density and para foveal superficial vascular plexus flow density before therapy were (521.44±190.27) μm, (21.85±6.17)% and (46.29±2.70)%, respectively. The FMT, foveal superficial vascular plexus flow density and para foveal superficial vascular plexus flow density decreased to (242.13±86.02) μm, (18.40±5.18)% and (44.75±3.40)%, respectively. There was significant statistical difference for them (P<0.001). Conclusion: Intravitreal injection of anti-VEGF is effective in the treatment of BRVO combined with macular edema. OCTA can effectively evaluate the clinical efficacy of anti-VEGF in the treatment of BRVO combined with macular edema.
