眼底血管造影联合频域光相干断层扫描同步检查法对渗出性老年性黄斑变性脉络膜新生血管的诊断价值

Objective To evaluate the diagnostic value of Heidelberg retinal angiography(HRA) combined with optical coherence tomography (OCT) to detect neovascularization (CNV) in exudative age-related macular degeneration (AMD) patients. Methods This is a cross-sectional study of a series of clinical cases. AMD diagnosis was established by international standard vision chart, Slit lamp microscope, direct or indirect ophthalmoscope examination. A total of 50 eyes (42 cases) of exudative AMD received HRA and frequency domain OCT scan. All 50 eyes received fundus fluorescein angiography (FFA) and frequency-domain OCT simultaneously, and among them 15 eyes also received indocyanine green angiography (ICGA) at the same time. FFA and ICGA were carried out by conventional methods, CNV was localized by real-time Localization technology of frequency domain OCT. In the radial and grid-like section from the areas with strong fluorescence, image acquisition settings are 7 μm fault for each frame, 30° intervals for radialsection, 10 vertical and 10 horizontal scan lines for grid-like section. CNV can be divided into 4 types (typical CNV, partial typical CNV, occult CNV, CNV scarring) according to their boundaries demonstrated in FFA. Based on the features of the OCT images, there were 3 types of integrated image (sub-RPE type, sub-retinal type and mixed type). Results CNV was detected in all 50 eyes. There were 4 eyes (8%) of typical CNV, 11 eyes (22%) of partial typical CNV, 32 eyes (64 %, including 27 eyes of RPE detachment and 5 eyes of passive late leakage) of occult CNV and 3 eyes (6%) of CNV scarring. There were 4 eyes (8%) of sub-RPE type (CNV under the RPE light band) , 16 eyes (32%) of sub-retinal type(interrupted light band of RPE and choroid capillary layer) and 30 eyes (60%) of mixed type of integrated image. Conclusion The image integration technology of the HRA and frequency domain OCT system provide a valuable tool to classify and measure CNV, which will benefit the clinical treatment of AMD patients.

Characteristics of Indocyanine Green Angiography in Exudative Age—related Macular Degeneration

Objective: To observe the characteristics of indocyanine green angiography (ICGA) in exudative age-related macular degeneration (AMD).Methods: Thirty-one cases (39 eyes) were diagnosed as exudative AMD by ocular examination, fundus color photography, fundus fluorescein angiography (FFA) and ICGA. Their ages ranged from 50 to 82 years and visual acuities from FC/30cm to 0. 7. We analyzed and compared the characteristics of ICGA and FFA in these patients. Results: Of 26 eyes with occult choroidal neovascularization (CNV) by FFA, 15 (57. 7% ) had classic CNV by ICGA. Of 4 eyes with serous retinal pigment epithelial detachment (FED) without CNV by FFA, 1 had serous FED with classic CNV by ICGA. The hyperfluorescence of the scar staining was detecfed by ICGA. Conclusion ? ICGA adds clinically useful information and is an important adjunct in the evaluation, classification, and laser treatment of patients with occult CNV in AMD.

正确认识和掌握高度近视黄斑病变的诊疗方法,减少高度近视患者视功能损害

以近视眼中心凹劈裂、黄斑裂孔及黄斑裂孔性视网膜脱离、近视性脉络膜新生血管为代表的高度近视黄斑病变是影响高度近视患者视功能的主要原因之一.光相干断层扫描检查有助于提升高度近视黄斑病变的认知水平.选择合适的手术时机,解除玻璃体后皮质和内界膜对视网膜的牵拉,有利于恢复视网膜的弹性,使近视眼中心凹劈裂消失.促进黄斑裂孔的闭合和视网膜复位;而抗新生血管药物与光动力疗法和(或)糖皮质激素联合应用,则是治疗近视性脉络膜新生血管的发展方向.正确认识和掌握高度近视黄斑病变的诊疗方法 和时机,采取针对性的干预措施.使其能够得到合理有效的治疗,是进一步减少高度近视患者视功能损害的关键.

病理性近视黄斑劈裂光相干断层扫描图像分型及其对临床的指导意义

病理性近视黄斑劈裂光相干断层扫描(OCT)的类组织学分型可以分为单纯外层劈裂、外层和中层劈裂、外层和内层劈裂、多层劈裂4种情况.以彻底清除玻璃体后皮质及后部血管弓内的内界膜为重点的玻璃体视网手术是治疗病理性近视黄斑劈裂的主要选择.其中,单纯外层劈裂合并中心凹脱离者,手术后视功能改善较明显;而多层劈裂者视功能改善有限或不改善.合理剥除后皮质与内界膜起始点,应在未发生内层劈裂处.正确认识和了解病理性近视黄斑劈裂的OCT分型.对于选择玻璃体视网膜手术方式和判断治疗预后有积极意义.

目的 观察脉络膜黑色素瘤的组织病理学特征。 方法 回顾分析64例病理确诊的脉络膜黑色素瘤病理资料。按照美国眼黑色素瘤多中心研究组的测量方法和WHO的分类标准，测量和观察大体标本中的肿瘤大小和光学显微镜下的肿瘤细胞学类型；以肿瘤前缘累及部位对肿瘤所处位置进行分类；以肿瘤细胞向外浸润程度对肿瘤蔓延程度进行分级。 结果 64例脉络膜黑色素瘤中，大肿瘤25例，占39.1%；中等大小肿瘤31例，占48.4%；小肿瘤8例，占12.5%。梭形细胞型42例，占65.6%,其中，梭形细胞A型15例,占23.4%，梭形细胞B型27例,占42.3%;上皮样细胞型7例,占10.9%;混合型10例,占15.6%;其它型5例,占7.8%。肿瘤细胞未累及巩膜者25例,占39.1%;累及巩膜但限于巩膜层内者22例,占34.4%;穿透巩膜全层达眼球表面者12例,占18.7%;眶内浸润者5例,占7.8%。 结论 脉络膜黑色素瘤组织病理学特征变化多样，临床上以梭形细胞型最常见，易伴巩膜浸润。 (中华眼底病杂志, 2006, 22: 161-165)     

病理性近视黄斑裂孔患者黄斑区视网膜前膜的组织学观察

目的 观察病理性近视内界膜表面结构的组织学变化与黄斑裂孔发生发展的关系.方法 同顾分析行玻璃体切割手术的病理性近视黄斑裂孔患者34例34只眼的临床资料.患眼屈光度均超过-6.00 D,眼轴26.00～33.12 mm,平均眼轴长度27.74 mm.5只眼为黄斑裂孔无视网膜脱离(黄斑裂孔组),29只眼为黄斑裂孔合并后极部视网膜浅脱离(视网膜脱离组).对入选患眼行睫状体平坦部三切口的玻璃体切割手术,手术中观察Weiss环以判断玻璃体后脱离程度,获取34只眼的视网膜前膜及19只眼的内界膜组织标本,行苏木精-伊红(HE)及醋酸铀-枸橼酸铅双染色,采用光学及透射电子显微镜观察.结果 玻璃体切割手术中,5只眼出现Weiss环,24只眼的视网膜表面有多层玻璃体组织残留.光学显微镜观察发现,内界膜表面的视网膜前膜主要由玻璃体胶原纤维.星形胶质细胞及细胞外基质组成.透射电子显微镜观察发现,19只眼的内界膜标本中,5只眼可她内界膜一玻璃体胶原纤维-细胞的"三明治"样结构,1只眼可见内界膜损伤、表面组织牵引和星形胶质细胞移行.结论病理性近视玻璃体后界面劈裂、内界膜表面组织结构的变化是黄斑裂孔发生发展直至视网膜脱离的重要原因.
