Purpose:To study the clinicopathological change on "Multiple Evanescent White-dot Syndrome (MEWDS)" through fundus angiogrphy analyses.Methods:Examing the case with fluorescein angiography (FFA) and indocyanine green angiography(ICGA), visual field and following up for 15 months.Results:There exist multiple white dots in the fundus photo and angiography. The changes on ICGA maintain longer than fundus photo and FFA. Papille may be edematous and macula could present with special hypofluorescent flecks.Conclusions:MEWDS has specific angiographic features. Its pathological changes involve deep retinal pigment epithelium(RPE) as well as choroidal capillaries. The prognosis of the visual acuity for MEWDS is very good.

Purpose:To observe different features of indocyanine green angiography(ICGA) and multifocal electroretinography(ERG)in the diffuse and regional type of Bieti‘s crystalline retinopathy(BCR).MEthods:ICGA and the multifocal ERG were performed in two cases of the diffuse and regional type of BCR respectively.These data were compared with fluorescein angiography(FA),Standard Ganzfeld ERG,and visual field testing.Results:In the regional case,ICGA revealed reduced perfusion of the choroidal circulation in the early phase and multiple hypofluorescent spots in the posterior pole in the late phase,due to choriocapillaris filling defect;the extent of choroiocapillaris loss was shown in early phase of ICGA and there were multifocal hyperfluorescent dots surrounding hypofluorescent spots in late phase in the diffuse case.The multifocal ERG showed that the central responses were markedly depressed,corresponding to the visual field defects,while the findings of Ganzfeld ERG were normal in the regional BCR;However,both the multifocal ERG and Ganzfeld ERG were severely subnormal in the diffuse case.Conclusions:The features of ICGA and multifocal ERG are different between the diffuse and regional BCR.In the meantime,the two tools are also useful to differentiate the type and assess the extent of evolution in BCR.  相似文献

Purpose:To report a case of a macular hole in a female adult with bilateral Coats disease.Methods:The fundus photograph, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in two eyes, and observed theirs characters.Results:Fundus photograph showed massive yellowish-white exudation in the temporal midperiphery of both eyes, but the degree was slighter in the right eye. There was 1/3 DD macular hole in left eye. FFA revealed general dilatation of capillaries, multiple aneurysms, and tortuous and closure of vessels in superotemporal midperiphery in both eyes, but the degree was slighter in the right eye. There was a one-third DD round transmitted fluorescence according the macula hole. ICGA revealed that hyperfluorescence of aneurysms in superotemporal midperiphery, the images of aneurysms were more clearly than in FFA. There was a 2/3 DD hypoflurescence of macula in the late phase of angiography.Conclusions: FFA and ICGA have respective advantage in revealing vas  相似文献

目的:探讨眼底荧光血管造影不能确定出血原因的黄斑出血的原发病灶。方法:对18例(20眼)不明原因黄斑出血作了吲哚青绿脉络脉络膜血管造影检查及分析。结果:本文结果表明导致不明原因黄斑出血的原发病灶有三类:脉络膜新生血管形成、视网膜血管异常和黄斑区偶发性出血。其中脉络膜新生血管导致的不明原因黄斑出血占多数(14眼),而由视网膜血管异常(3眼)和黄斑区偶发性出血(3眼)所致的不明原因黄斑出血比率较少。结论:吲哚青绿脉络膜血管造影对揭示不明原因黄斑出血的原发病灶有非常重要的价值。眼科学报 1997;13:62~66。  相似文献

目的:观察老年黄斑变性(AMD)对视网膜黄斑部电活动影响特征,并对局部视网膜电图(LERG)的敏感性作出评价。方法:对80例AMD患者99只眼进行了黄斑区三个范围局部视网膜电图(LERG)测定,并与患者的视力及相应检测范围病损面积进行了对比研究。结果:黄斑区2.5°、5°、7.5°范围内,干性AMD组LERG平均振幅降低,但与正常对照组间无显著性差异(P>0.05),湿性AMD组LERG平均振幅显著降低(P<0.01)。湿性AMD LERG b波振幅与病人视力呈正相关性,与相应范围病灶面积呈负相关。干性AMD玻璃膜疣数量对LERG尚无影响。结论:不同类型AMD对于黄斑功能损害程度不同,湿性型损害大于干性型;中心凹功能损害大于旁中心凹。LERG在AMD的黄斑功能测定方面是较敏感的电生理方法。眼科学报 1996;12:93—97。  相似文献

综述了老年性黄斑变性(AMD)近几年的研究现状,包括AMD的流行病学,病因学,病理机制和中西医治疗等。其中AMD的发病与年龄,人种,遗传史,吸烟,环境等因素有关;病理机制与视网膜色素上皮的代谢障碍和慢性非特异性炎症性病变有关;治疗方法主要有激光光凝,光动力学,手术,放射,基因,药物等。由于目前对AMD的治疗尚无确切疗法,应用中医药进行治疗是一个值得探索的方向。  相似文献

Forty-one patients with age-related macular degeneration(AMD) were detected for serum autoantibodies against normal humanretinal protein by means of Western immunoblot analysis.Twenty-sevenout of the 41 patients showed positive response,with a rate of 66 percent.The positive rate of antiretinal antibody in the AMD patients wassignificantly higher than that in normal controls (18%) and in patients withother retinal diseases (24%) (p<0.0005).These antiretinal antibodies fromthe AMD patients partly reacted with the retinal protein of molecular weightbetween 28 and 32 Kd,partly with Mr of 38 to 42 Kd,48 to 52 Kd,62 to65 Kd or 110 to 130 Kd.Of them,the antiretinal antibody against theprotein with Mr of 28 to 32 Kd in the AMD patients was higher than innormal controls (p<0.05).Two or more antibodies were found in theserum from AMD patients,showing a significant difference between thepatients and the controls (p<0.005).The results indicated that in theoccurrence of AMD and/or during its developing process there wereinflammation and immunological response,involving antibodies againstretinal proteins of various molecular weight.Eye Science 1993;9:113-120.  相似文献
