国产过氟三丁胺在视网膜巨大裂孔手术中的应用

使用国产过氟三丁胺液（perfluorotribulylamine liguid,PFTL）治疗视网膜巨大裂孔21眼，其中裂孔后缘重叠翻卷粘连固定者5眼，复杂性视网膜脱离手术中作视网膜切开形成的巨大裂孔16眼。视网膜复位率＞95%，无明显的副作用。文章还讨论了过氟三丁胺在视网膜巨大裂孔手术中的作用和并发症。 （中华眼底病杂志，1996，12：22-24）     

VITRECTOMY TECHNIQUES IN THE TREATMENT OF GIANT RETINAL TEARS: A FLEXIBLE APPROACH

We describe a flexible approach employing vitrectomy, scleral buckling and intraocular tamponading agents in the treatment of giant retinal tears. Intraocular gas without a buckle was used in the 10 least complicated cases. In five eyes we considered a scleral buckle to be necessary in addition to gas tamponade. Silicone oil was selected as the primary tamponading agent in the six most complex cases with PVR and in five re-operations. The overall anatomical success rate was 71 % of which 73% had a final visual acuity of at least 6/60 and 60% achieved 6/18 or better.     

PERIPHERAL RETINAL TEARS: CLASSIFICATION, PREVALENCE AND PRINCIPLES OF MANAGEMENT

In summary, full-thickness peripheral retinal tear is classified in relationship to the vitreous base as intrabasal, juxtabasal and extrabasal. Each of these categories of full-thickness retinal tear is usually associated with characteristic lesions that are particularly likely to produce full-thickness retinal tears in the respective zones. In overall prevalence, full-thickness peripheral retinal tears, excluding retinal tears at the ora serrata, are present at autopsy in 3.3% of patients, are bilateral in 11.2% of affected patients, and are present in 1.9% of eyes. In conjunction with full-thickness retinal tears, principles of management are reviewed     

马蹄形裂孔与增殖性玻璃体视网膜病变

裂孔性视网膜脱离术后发生严重PVR的危险眼只限于马蹄形裂孔的这些眼,为了阐明马蹄形裂孔发生PVR的机制及其两者关系.本文分析了单纯马蹄形裂孔性视网膜脱离手术失败的101眼,病例分为PVR组和无PVR组,两组病例对照比较.结果表明:玻璃体液化和后脱离是马蹄形裂孔发生PVR的基本原因.玻璃体出血、葡萄膜炎、脉络膜脱离、多次手术是PVR发生的促进因素,而裂孔后缘卷边固定与前瓣比其下暴露的色素上皮区小是PVR己发生的临床证据.因此当临床上出现玻璃体出血、葡萄膜炎、脉络膜脱离及第一次手术没成功时要警惕术后发生严重的PVR.     

先天性视网膜色素上皮肥大对家族性腺瘤性息肉病的筛查

对8例家族性腺瘤性息肉病(FAP)5名I级高危亲属和100例对照组作眼底色素病变研究。结果表明：先天性视网膜色素上皮肥大对FAP有筛检价值，若色素斑有晕圈、数量≥4颗、病变为双眼且位于后极部，则FAP的可能性很大。 （中华眼底病杂志，1995，11：1-3）     

RELIABILITY OF,DIFFERENCE AND CORRELATION BETWEEN FAR AND NEAR HYPERPHORIAS

Far and near hyperphorias were obtained from three groups of subjects, 25 each. Retest reliability from group 1 was high (0.96 and 0.99). Far then near hyperphorias from group 2 was highly correlated (0.94). Near then far hyperphorias from group 3 was not Significantly correlated. Frequency of occurrence of hyperphorias in. the reversed order of near then far measurement was significantly higher than that in the usual order of far then near, indicating influence of some undetermined sources. No significant difference was found between any comparison of the means. Thus, near hyperphoria may be omitted in the usual order of clinical measurement.
