息肉样脉络膜血管病变的光相干断层扫描

目的 :观察息肉样脉络膜血管病变 (polypoidalchoroidalvasculopathy ,PCV )的光相干断层扫描 (opticalcoherencetomography ,OCT)图像特征。方法 :对比分析常规眼底检查、荧光素眼底血管造影 (fundusfluoresceinangiography ,FFA )及吲哚青绿血管造影 (indocyaninegreenangiography ,ICGA)检查确诊的PCV患者 9例 9眼 (PCV组 )、渗出型老年性黄斑变性 (exudativeage -relatedmaclarde generation ,AMD)引起的浆液性视网膜色素上皮脱离 (retinalpigmentepithelialdetachments ,RPED) 11例 11眼、中心性渗出性脉络膜视网膜病变 (centralexudativechoroidoretinopathy ,CEC)引起RPED 2例 2眼 (浆液性RPED组 )的OCT检查图像资料 ,观察PCV患眼视网膜下结节样病灶特征、RPED隆起高度和基底宽度的相关性。结果 :PCV眼OCT图像表现为RPE和脉络膜毛细血管高反射层呈穹隆状隆起 ,表面不规则 ,边缘陡峭。其下或视网膜色素上皮 (retinalpigmentepithelial ,RPE)光带水平可见结节样改变。 3眼有RPED ,5眼RPED合并神经上皮脱离。RPE隆起高度和基底宽度比率 :PCV组 (0 14 5 1± 0 0 40 0 )较浆液性RPED组 (0 0 876± 0 0 3 2 5 )高 (t =-3 3 2 4,P =0 0 0 4) ,高度和基底宽度呈线形关系 ,且PCV组直线较浆液性PED组     

OCTA与ICGA检查在CNV和PCV中的影像对比分析

目的：对比观察脉络膜新生血管(CNV)与息肉状脉络膜血管病变(PCV)在吲哚菁绿血管造影(ICGA)与光学相干断层扫描血管成像(OCTA)中的特征性表现,探讨二者的区别和优缺点。

方法：回顾分析2018-09/2020-04在河北省眼科医院确诊的CNV患者26例34眼和PCV患者19例19眼的影像学资料,CNV患者中湿性年龄相关性黄斑变性(w-ARMD)20例28眼,慢性中心性浆液性脉络膜视网膜病变(CCSC)继发CNV 6例6眼。所有患者均行OCTA、荧光素眼底血管造影(FFA)+ICGA检查,分析其特征性改变。

结果：w-ARMD患者28眼OCTA检查示,除2眼因出血较多未见明显异常外,余26眼均可显示CNV形态,呈现效果形态更加锐利、立体,且能够分辨出CNV所在的解剖层面,其中11眼OCTA检查不仅能够很好地显示出CNV的形态、大小、范围,而且对于CNV中的滋养血管、新生血管及吻合支也都能较好地分辨。CCSC继发CNV患者6眼OCTA发现了FFA+ICGA未发现的CNV形态。PCV患者19眼OCTA检查异常脉络膜分支血管网(BVN)显示优于ICGA,但OCTA图像上末端囊袋样扩张(polyps)的显示及数量不如ICGA明显,部分不能显示。

结论：OCTA检测CNV阳性率较ICGA高,检测CNV和PCV病变范围较ICGA更清晰、立体,但在PCV中不能全部显示末端囊袋样扩张,且不能观察CNV或PCV渗漏情况及病变动态发展过程,较 FFA+ICGA尤为不足。OCTA作为无创检查可以随访观察CNV或PCV治疗前后病变发展情况。     

息肉样脉络膜血管病变的诊断及治疗

息肉样脉络膜血管病变(polypoidal choroidal vasculopathy,PCV)特征是后极部视网膜下桔红色息肉样病变,伴有出血性和浆液性视网膜色素上皮及神经上皮脱离.荧光素眼底血管造影无特征性表现,吲哚青绿血管造影能显示分支血管组成的脉络膜血管网和血管末端息肉样或动脉瘤样扩张.OCT表现为视网膜色素上皮及脉络膜毛细血管高反射层呈陡峭的穹窿状隆起,其下见中等反射或结节状改变.本病应与湿性年龄相关性黄斑变性和某些长期不愈的中心性浆液性脉络膜视网膜病变进行鉴别.尽管PCV的治疗仍缺乏通用的方案,光动力疗法结合玻璃体内注射血管内皮生长因子抑制剂可改善或稳定患者视力.

目的探讨息肉状脉络膜血管病变(PCV)与湿性老年黄斑变性(AMD)临床特征的区别与联系,以指导临床。方法回顾分析已确诊的PCV及湿性AMD的眼底彩照,荧光素血管造影(FFA),吲哚青绿血管造影(ICGA),光学相干断层扫描(OCT)结果及临床资料。结果PCV15例,年龄48-70岁,平均62.3岁;湿性AMD38例,年龄50-80岁,平均65.8岁。PCV患者眼底视网膜出血、脂质渗出、桔红色结节样病灶分别为11只眼(73.3%)、6只眼(40%)、4只眼(26.7%);AMD患者45只眼中视网膜出血、脂质渗出、青灰色病灶、瘢痕形成分别为25只眼(55.6%)、18只眼(40.0%)、20只眼(44.4%)、3只眼(6.77%)。FFA显示PCV患眼脉络膜息肉状结构、出血性色素上皮脱离(PED)、浆液性PED分别为1只眼(6.7%)、7只眼(46.7%)、2只眼(13.3%),ICGA均可见息肉状扩张病灶(100%);FFA显示AMD患眼典型脉络膜新生血管(CNV)、PED分别为5只眼(11.1%)、14只眼(31.1%),ICGA显示CNV23只眼(51.1%),均未见息肉状结构。PCV的OCT表现为视网膜色素上皮及脉络膜内层呈穹窿状向视网膜神经上皮隆起,其下见结节状改变;AMD则显示视网膜色素上皮和脉络膜毛细血管层呈局部梭形或不规则强反射带。结论PCV与湿性AMD不尽相同,可能是AMD的另一种特殊类型,治疗可能应有所不同,有待于进一步研究。     

Pigment epithelial detachment in polypoidal choroidal vasculopathy

PURPOSE: To study the morphological features of serosanguineous pigment epithelial detachments (PEDs) with accompanying polypoidal lesions in eyes with polypoidal choroidal vasculopathy (PCV). DESIGN: Retrospective observational case series. METHODS: For this observational case study, we retrospectively reviewed 93 consecutive eyes of 85 patients with PCV. The lesions in eyes with PCV were examined with indocyanine green angiography (IA) and optical coherence tomography (OCT). RESULTS: Of 93 eyes with PCV, 51 eyes (55%) had serous or hemorrhagic PEDs. Of these 51 eyes, a notch in the PED was found in 27 eyes (53%) by angiography, most of which showed polypoidal lesions by IA that corresponded in location to the notch observed by angiography. Polypoidal lesions were detected outside the PED in one eye (2%), at the margin of the PED in 33 eyes (65%), and inside the PED in 12 eyes (24%). OCT revealed that PED had a notch observed tomographically in 29 eyes (57%), most of which corresponded in location to polypoidal lesions seen by IA. In eight eyes, polypoidal lesions, which were adherent to the inner surface of the serous PED, appeared to be detached from the Bruch membrane and the choroid. CONCLUSIONS: Polypoidal lesions are located at the margin of PED and make a notch in the accompanying PED that is visible by angiography and tomographically. When the polypoidal lesions have increased exudate, the fluid from the lesions infiltrates under the polypoidal lesions themselves, which results in the lesions detaching from the Bruch membrane and appearing to be located inside the PED.     

Comparison of OCT and OCTA manifestations among untreated PCV, neovascular AMD, and CSC in Chinese population

AIM: To compare the qualitative and quantitative features among untreated polypoidal choroidal vasculopathy(PCV), neovascular age-related macular degeneration(nv-AMD) and central serous chorioretinopathy(CSC) using optical coherence tomography(OCT) and OCT angiography(OCTA).METHODS: This retrospective study included 16 eyes with thin-choroid PCV, 18 eyes with thick-choroid PCV, 16 eyes with nv-AMD and 17 eyes with CSC, respectively. The indicators were obtained by OCT and OCTA.RESULTS: Sub-foveal choroidal thickness(SFCT) in CSC was thicker compared to other groups(all P<0.05). SFCT in nv-AMD was thicker compared to thin-choroid PCV, but thinner compared with thick-choroid PCV(both P<0.05). As the ratio of thickness of Haller's layer to thickness of SFCT, which of thin-choroid PCV was significantly higher than CSC(P<0.001). Likewise, thick-choroid PCV had significantly higher ratio than nv-AMD(P=0.016) or CSC(P<0.001). There were differences among them in pigment epithelium detachment(PED). The whole-superficial retinal vessel density(RVD), deep RVD and choroidal capillary vessel density(CCVD) in CSC were significantly higher compared to other three groups, respectively(all P<0.05). The whole CCVD in nv-AMD was higher compared to thick-choroid PCV(P=0.032). Cross-sectional local angiographic form was 87.50%, 83.33%, 0 and 35.29% in thin-choroid PCV, thickchoroid PCV, nv-AMD and CSC, respectively. Cross-sectional diffuse angiographic form was 12.50%, 16.67%, 100% and 5.88% in thin-choroid PCV, thick-choroid PCV, nv-AMD and CSC, respectively.CONCLUSION: Combination of OCT and OCTA can effectively observe the significant alterations existed in PCV, CSC and nv-AMD, and there are distinctive differences among them. The pathogenesis is not exactly the same between PCV and nv-AMD, or PCV and CSC.

Clinical characteristics of polypoidal choroidal vasculopathy in Chinese patients

Purpose

To describe the clinical characteristics of polypoidal choroidal vasculopathy (PCV) in a large number of Chinese patients.

Methods

This study enrolled 204 consecutive patients (246 eyes) in our department who were diagnosed as having polypoidal choroidal vasculopathy PCV. Patients underwent ophthalmologic examinations including best-corrected visual acuity (BCVA) testing, ophthalmoscopy, fundus photography, fluorescein angiography, indocyanine green angiography, and optic coherence tomography.

Results

Mean patient age was 66.1?years and 60.3% were men. Of the cases, 79.4% were unilateral and 51.2% of BCVA was less than 35 letters. In 171 eyes (69.5%), polypoidal lesions were located in the macula area. Among them, polypoidal lesions were located in the foveal area in 29 eyes (11.8%), in the parafoveal area in 50 eyes (20.3%), and in the extrafoveal area in 88 eyes (35.8%), in both the foveal and parafoveal area in three eyes (1.2%), and in both the parafoveal and extrafoveal area in one eye (0.4%). In 37 eyes (15.0%), PCV lesions were under the temporal retinal vascular arcade; in 11 eyes (4.5%), PCV lesions were found peripapillary. PCV lesion formation was single in 88 eyes (35.8%), cluster in 145 eyes (59.0%), string in two eyes (0.8%), and branch in two eyes (0.8%). In nine eyes (3.6%), the formation of PCV lesions showed both single and cluster shape in the same eye. There were 54.5% with drusen, 44.7% with serous PED, 20.7% with hemorrhagic PED, and 39.0% with neuroretinal detachment.

Conclusions

The majority of Chinese PCV patients were male, unilateral, and showed macular polyps. Drusen, serous PED, hemorrhagic PED, and neuroretinal detachment on OCT were commonly seen.
