Objective Observation on the characteristics of choroidal melanomas with indocyanine green angiography (ICGA) and fundus fluorescsin angiography(FFA). Methods Both ICGA and FFA were used in 16 cases of choroidal melanoma for comparison and analysis. Results 81.2% of tumors showed hypofluorescence all the way or faint fluorescence in later stage．62.6% of tumors had characteristic intrinsic tumor vassels with ICGA,while 12.5% of tumors had intrinsic vessels with FFA．Those tumors that can't be diagnosed owing to whole hyperfluorescence in later stage with FFA may be diagnosed by visibility of intrinsic tumor vessels with ICGA. Conclusion ICGA is helpful in the diagnosis of choroidal melanoma. (Chin J Ocul Fundus Dis, 2000，16：3-5)
目的:探讨鼻咽癌延误诊断的原因。从而提高鼻咽癌患者的早期诊断率,改善治疗效果。方法: 回顾性分析324例在我科接诊前因各种因素而延误诊断的鼻咽癌患者首发症状、首诊误诊科室、误诊疾病。结果: 本组病例首发症状分别为颈部包块138例(42.5%)、鼻部症状148例(45.6%)、耳部症状66例(20.3%)、头痛46例(14.2%)、其他17例(5.2%),有两种首发症状的病例为91例。首诊误诊的疾病有颈部淋巴结炎、慢性鼻鼻窦炎、鼻出血、分泌性中耳炎、脑动脉硬化等27种疾病。涉及普外科、耳鼻咽喉科、神经内科、骨科、呼吸内科、口腔科、烧伤科、眼科、中医科等9个科室。结论: 加强鼻咽癌知识普及,完善继续医学教育及住院医师培训,积极寻找鼻咽癌的早期诊断方法能减少鼻咽癌的延误诊断。
Objective To evaluate the diagnosis of blue-on-yellow perimetry and macular threshold perimetry in early primary glaucoma. Methods Humphrey II 750 automatic perimetry was used to test 60 eyes of 60 cases in normal control group and 63 eyes of 63 cases in early primary glaucoma group with white-on-white perimetry (W/W), blue-on-yellow perimetry (B/Y)，and macular threshold perimetry (M TP). The results of the visual field defects detected by the three perimetries were compared and analyzed.Results The differences of mean sensibility of W/W, B/Y and MTP between the two groups had statistical significance［t=-3 .01, P=0.0054 (W/W); t=-2.95, P=0.006 3 (B/Y); t=-2.59,P=0. 0150 (MTP)］. In the diagnosis of early primary glaucoma, the sensitivity of MTP was the highest (83%), B/Y was the second (65%), and W/W was the lowest (48%). When B/Y and MTP were combined, the sensitivity was improved to 94% using parallel testing, and the specificity was improved to 87% using serial testing.Conclusions B/Y and MTP are valuable in diagnosis of early primary glaucoma, and the sensitivity and specificity of the diagnosis can be improved when B/Y and MTP are combined.

目的 总结胰腺实性假乳头状瘤（solid-pseudopapillary tumor of pancreas, SPTP）的诊治经验。方法 回顾性分析我院1999年11月至2007年10月期间收治的6例SPTP患者的临床资料。结果 6例均为女性，其中4例为年轻女性； 术前均未确诊； 行胰腺体尾部切除2例，肿瘤局部切除4例，其中2例加脾切除，术后病理报告确诊为SPTP。 术后无严重并发症，随访1～95个月，无复发和转移。结论 SPTP多发于年轻女性，术中冰冻切片对术中处理提供参考，手术切除为首选治疗方法，预后良好。
