目的探讨利用B型超声检查和眼底检查相结合来观察急性PVD时的玻璃体和视网膜的情况。方法通过对2003.7-2003.10期间有症状的急性PVD患者55人55眼进行临床检查和分析。所有患眼均经B超作细致的全周探测,之后由检眼镜、VOLK90D、三面镜检查眼底情况。结果55眼经B超检查发现完全性PVD有41眼,部分性PVD为14眼。后界膜大多表现为后部纤细的中低回声光带,柔软并具有明显的后运动度。B超发现周边部存在中高回声条块和后界膜相连,并怀疑为视网膜裂孔的有8眼,经眼底检查确诊的有5眼。B超发现有7眼增厚的后界膜对视网膜有牵引感,经眼底检查均未发现裂孔。有一眼眼底检查发现周边马蹄形干孔,而超声检查未注意到。结论B超是探查PVD完全性和视网膜裂孔最简单、有效的方法,可以为诊治和预后提供全面的指导。大多完全性PVD的玻璃体有明显的液化、塌陷。在部分性PVD患眼,则需重视后界膜与视网膜粘连处的变化。
Objective To explore the use of B-mode ultrasonography combined with fundus examination to observe the vitreous and retina during acute PVD. Methods Clinical examination and analysis of 55 eyes of 55 patients with symptomatic acute PVD during 2003.7-2003.10. All eyes were B-meticulous for the whole week of exploration, followed by ophthalmoscope, VOLK90D, three-mirror examination fundus situation. Results Of the 55 eyes, B-ultrasound examination revealed 41 eyes with complete PVD and 14 eyes with partial PVD. The posterior membrane showed mostly posterior slender hypoechoic band, which was soft and had significant post-exercise degree. B-ultrasound found in the peripheral part of the existence of high echo block and the posterior boundary membrane connected to the suspected retinal holes and 8 eyes confirmed by the fundus examination of 5 eyes. B-found that there are seven thickening of the posterior limiting membrane on the retina traction sense by the fundus examination were not found in the hole. One eye examination revealed a horseshoe-shaped dry hole around, while the ultrasound did not notice. Conclusion B-ultrasonography is the simplest and effective method to explore PVD completeness and retinal breaks, which can provide comprehensive guidance for diagnosis and prognosis. Most of the PVD vitreous body has obvious liquefaction, collapse. In partial PVD eyes, you need to pay attention to the posterior and membranous retinal changes in adhesion.
