This study aimed to evaluate the ability and role of ultrasound biomicroscopy in imaging the peripheral retina, pars plana, and anterior choroid.
The study design was a case series.
Seventeen eyes of 17 patients with a variety of clinical diagnoses involving the anterior portion of the posterior segment were studied.
High-frequency (50 MHz), high-resolution (50 microns) ultrasound biomicroscopy was performed.
Ultrasound biomicroscopy was capable of imaging the peripheral retina, pars plana, and anterior choroid. Images had features consistent with known histopathology. Retinoschisis consisted of one thin hyper-reflective echo and could be differentiated from a retinal detachment, which was thicker and formed a bilayered echo. A choroidal effusion could be identified as an echolucent space within the suprachoroidea, whereas a choroidal hemorrhage was moderately echodense. Inflammatory diseases, such as a sarcoid granuloma, pars planitis, and Harada's disease, were characterized by different forms of uveal thickening. A ciliochoroidal nevus was internally hyporeflective and could be measured accurately and localized.
Imaging of the peripheral retina, pars plana, and anterior choroid is possible with ultrasound biomicroscopy and may aid in the diagnosis and management of pathology involving this region.
本研究旨在评估超声生物显微镜对外周视网膜、睫状体扁平部及脉络膜前部成像的能力及作用。
本研究设计为病例系列研究。
对17例患有涉及眼后段前部各种临床诊断疾病的患者的17只眼睛进行了研究。
采用高频(50兆赫)、高分辨率(50微米)的超声生物显微镜检查。
超声生物显微镜能够对外周视网膜、睫状体扁平部及脉络膜前部进行成像。图像具有与已知组织病理学一致的特征。视网膜劈裂表现为一个薄的高反射回声,可与视网膜脱离相鉴别,后者更厚且形成双层回声。脉络膜积液可表现为脉络膜上腔内的无回声区,而脉络膜出血则为中等回声密度。结节病性肉芽肿、睫状体扁平部炎和原田病等炎症性疾病表现为不同形式的葡萄膜增厚。睫状脉络膜痣内部回声低,可准确测量并定位。
超声生物显微镜可对外周视网膜、睫状体扁平部及脉络膜前部进行成像,有助于诊断和处理涉及该区域的病变。
