肥厚型脉络膜谱系疾病与脉络膜、涡静脉、巩膜改变的研究进展

Research progress of pachychoroid disease spectrum and changes in the choroid, vortex veins and sclera

:693-699
 
肥厚型脉络膜谱系疾病(pachychoroid disease spectrum,PCD)包括肥厚型脉络膜色素上皮病变(pachychoroid pigment epitheliopathy,PPE)、中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy,CSC)、肥厚型脉络膜新生血管病变(pachychoroid neovasculopathy,PNV)、息肉样脉络膜血管病变(polypoidal choroidal vasculopathy,PCV)、局灶性脉络膜凹陷(focal choroidal excavation,FCE)和盘周肥厚型脉络膜综合征(peripapillary pachychoroid syndrome,PPS)。有学者将PCD看作脉络膜功能障碍引发的一系列连续疾病过程,但关于PCD的发病机制、形态改变尚未明确。该文对PCD的脉络膜、涡静脉及巩膜相关改变做一综述。

Pachychoroid disease spectrum include pachychoroid pigment epitheliopathy, central serous chorioretinopathy, pachychoroid neovasculopathy, polypoidal choroidal vasculopathy, focal choroidal excavation, and peripapillary pachychoroid syndrome. Currently, some scholars regard pachychoroid disease spectrum as a series of continuous disease processes caused by choroidal dysfunction, but the pathogenesis and morphological changes of pachychoroid disease spectrum are not yet clear. This paper reviews the changes of choroid, vortex veins and sclera in pachychoroid disease spectrum.

Visual prognosis of vitrectomy for polypoidal choroidal vasculopathy with breakthrough vitreous hemorrhage

Visual prognosis of vitrectomy for polypoidal choroidal vasculopathy with breakthrough vitreous hemorrhage

:45-55
 
Aim: The objective of this study was to investigate the prognosis of massive vitreous hemorrhage(VH) secondary to polypoidal choroidal vasculopathy(PCV) after vitrectomy.  

Methods:
Forty-nineeyes in 48 patients with PCV and breakthrough VH who underwent 23-gauge pars plana vitrectomy between January 2015 and December 2020 were enrolled. The main outcome parameters were best-corrected visual acuity, postoperative adverse events, and reoperation.

Results:
The average follow-up time was 20.0±15.82 months. The average preoperative best-corrected visual acuity (BCVA) was 2.12±0.65 logarithm of the minimum angle of resolution (logMAR), the BCVA at six monthswas 1.65±0.64 logMAR, and the six-month follow-up BCVA was 1.67±0.76 logMAR. Compared to the average preoperative BCVA, the six-months and last follow-up BCVA after vitrectomy improved (P<0.05). The BCVAat the fnal follow-up was better than 1.3logMAR only in 14 eyes (28.6%). Postoperative complications were observed in 10 eyes (20.4%), including recurrent retinal detachment, recurrent vitreous hemorrhage, macular hole, hyphema and lens dislocation. Fourteen eyes(28.6%) underwent cataract surgery procedure an average of 10.16±5.14 months after vitrectomy. BCVAone week and three monthsafter cataract surgery improved compared toBCVAbefore cataract surgery (P<0.05). Hypertension was associated with BCVAsix months after vitrectomy (P=0.017). The BCVA at baseline and three months after PPV were worse in patients who underwent vitrectomy combined with silicone oil filling (P<0.05). Eyes with postoperative complications had worse BCVA at six months, 12 months, and at the final follow-up after PPV (P<0.05).The duration of VH is related to the BCVA12 months after PPV visual acuity after surgery. Patients who underwent vitrectomy within one month of the onset of vitreous hemorrhage had better BCVA 12 months after vitrectomy than those who underwent vitrectomy surgery one month later (P=0.015). 

Conclusions: 
Although the prognosis of vitrectomy varies greatly, cataract surgery could be considered to improve BCVAif polypoidal lesions are inactive six months after vitrectomy.

影响孔源性视网膜脱离手术抉择相关临床因素的研究进展

Research progress in clinical factors affecting surgical decisions for rhegmatogenous retinal detachment

:504-511
 
孔源性视网膜脱离(rhegmatogenous retinal detachment,RRD)是一种严重威胁视力的眼部疾病,目前治疗手段以手术为主,手术方式主要有视网膜气体填充术(pneumatic retinopexy,PR)、巩膜扣带术(scleral buckling,SB)以及经睫状体扁平部玻璃体切割术(pars plana vitrectomy,PPV)。目前对于RRD手术术式的选择仍然存在争议,因此研究及制定RRD手术方式抉择的临床策略具有重要的临床意义。而临床上制定RRD患者手术方案往往与患者的年龄、视网膜脱离时间、裂孔的类型、位置、数量、大小等等临床因素有关,该文就影响孔源性视网膜脱离手术抉择的相关临床因素进行综述。
Rhegmatogenous retinal detachment (RRD) is a serious eye disease threatening vision. Surgery is main treatment currently, and surgery approaches include pneumatic retinopexy (PR), scleral buckling (SB), and pars plana vitrectomy(PPV). There is still controversy over the selection of RRD surgery approaches, so it is great significant to study and develop clinical strategies for RRD surgery approaches. The surgical plans for RRD patients are often related to clinical factors, such as the patient’s age, retinal detachment time, type, location, quantity, size, etc. This article reviews the related clinical factors affecting the surgical decision for rhegmatogenous retinal detachment.

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.
