由于水库河段地处青藏高原东缘梯级地貌过渡带上,河流深切,山势雄伟,河谷两岸为高达百米至千米以上的陡峻岸坡,河谷主要未"V"形峡谷,地质构造背景复杂。所以本文重点结合该水库的地质构造条件,研究该库区段可能发生的邻谷渗... 由于水库河段地处青藏高原东缘梯级地貌过渡带上,河流深切,山势雄伟,河谷两岸为高达百米至千米以上的陡峻岸坡,河谷主要未"V"形峡谷,地质构造背景复杂。所以本文重点结合该水库的地质构造条件,研究该库区段可能发生的邻谷渗漏、绕坝渗漏、断层渗漏三种渗漏问题,并分析给出了三种渗漏发生的可能性大小,这对以后的工作有着很深远的意义。 展开更多

Objective To explore the diagnosis, classification, and management of uveal effusion syndrome (UES). Methods The clinical data of 10 patients diagnosed with UES in our hospital between 1990-2010 were extracted from hospital records and analyzed, including ophthalmologic examination, ophthalmologic ultrasonography, ultrasound biomicroscopy (UBM), fundus fluorescence angiography (FFA), indocyanine green (ICG) angiography, surgical procedures, and outcomes. Results The fundus examination of all impacted eyes showed bullous retinal detachment shifting with head position, confirmed by ultrasonography revealing retinal and choroidal detachment. UBM showed annular peripheral ciliochoroidal detachment in all cases. FFA was performed in 5 patients and revealed leopard spots without leakage from choroid into subretinal space. ICG angiograpy was performed in 3 patients and demonstrated diffused granular marked hyperfluorescence in the choroidal fluorescence in the very early phase, which increased with time and persisted until the late phase. Four eyes of 2 patients underwent full-thickness sclerectomies and 1 eye of 1 patient underwent subscleral sclerectomy, all of whom achieved reattachment of the retina without recurrence during 1-year follow-up. Conclusions Comprehensive preoperative evaluation, including ophthalmologic ultrasonography, computed tomography, and magnetic resonance imaging, is crucial for accurate classification of UES and selection of proper management strategy. Surgical treatment can achieve optimal clinical outcomes for type 1 and type 2 UES. 展开更多
