To determine the value of high frequency ultrasound biomicroscopy (UBM) in the assessment of pars planitis, and in particular to correlate UBM findings and ophthalmoscopy findings.
All patients with pars planitis were identified from the uveitis database of the Department of Ophthalmology, University of Aberdeen. Fifteen consecutive patients (age 14-52 years) underwent complete ophthalmological examination. UBM was performed at a sound frequency of 50 MHz on 17 eyes of 10 patients to determine the extent of disease. UBM findings were evaluated by two investigators in a blinded fashion and graded from 0 to 3 according to the following grading criteria: 0=no cells, 1=mild cells, 2=marked cells, 3=organization of cells. Opthalmoscopy findings were also graded using the same criteria. UBM and ophthalmoscopy findings were independently graded and compared.
We found a good inter-observer correlation for the UBM grading of pars planitis (rho=0.86). There was no significant difference in the grading of pars planitis by indirect ophthalmoscopy as compared to grading by UBM (P>0.05).
UBM appears to be a valuable and reliable diagnostic technique for the evaluation of patients with pars planitis and may be useful especially in patients with media opacities to diagnose and/or monitor efficacy of treatment.
确定高频超声生物显微镜（UBM）在评价睫状体平坦部炎中的价值，尤其是将UBM检查结果与检眼镜检查结果进行关联。
从阿伯丁大学眼科的葡萄膜炎数据库中识别出所有患有睫状体平坦部炎的患者。连续15例患者（年龄14 - 52岁）接受了全面的眼科检查。对10例患者的17只眼采用50MHz的超声频率进行UBM检查以确定疾病的范围。两名研究者以盲法评估UBM检查结果，并根据以下分级标准从0到3级进行分级：0 = 无细胞，1 = 少量细胞，2 = 大量细胞，3 = 细胞机化。检眼镜检查结果也采用相同标准进行分级。UBM和检眼镜检查结果分别独立分级并进行比较。
我们发现UBM对睫状体平坦部炎分级的观察者间相关性良好（rho = 0.86）。间接检眼镜检查对睫状体平坦部炎的分级与UBM分级相比无显著差异（P>0.05）。
UBM似乎是评估睫状体平坦部炎患者的一种有价值且可靠的诊断技术，尤其在伴有介质混浊的患者中，对于诊断和/或监测治疗效果可能有用。
