目的分析超声检查在玻璃体混浊疾病诊断中的作用与不足,以提高超声诊断的准确性。方法分析105例超声诊断为玻璃体混浊病例的临床资料。结果近视性玻璃体混浊55例,老年性玻璃体混浊15例,玻璃体积血12例,玻璃体变性9例,少量硅油残留4例,确诊101例,确诊率96.2%,误诊4例,误诊率3.8%。结论超声检查在玻璃体混浊的诊断中有很大的优势,但仪器增益调节不当、忽略病史、忽视声像图相似疾病的鉴别诊断等都会导致误诊。
Objective To analyze the role and deficiency of ultrasonography in the diagnosis of vitreous opacity to improve the accuracy of ultrasonic diagnosis. Methods Clinical data of 105 cases diagnosed as vitreous opacity by ultrasonography were analyzed. Results There were 55 cases of myopic vitreous opacity, 15 cases of senile vitreous opacity, 12 cases of vitreous hemorrhage, 9 cases of vitreous degeneration and 4 cases of small residual silicone oil. There were 101 cases diagnosed, 96.2% diagnosed and 4 misdiagnosed cases. The misdiagnosis rate was 3.8%. Conclusions Ultrasonography has great advantages in the diagnosis of vitreous opacity. However, improper adjustment of instrument gain, ignoring medical history, ignoring the differential diagnosis of similar diseases of sonography can lead to misdiagnosis.
