Ocular toxocariasis most commonly presents as one of three distinct clinical syndromes: endophthalmitis, localized posterior granuloma, or peripheral granuloma. Using standardized echography, the authors studied 11 toxocariasis patients presenting with one of these syndromes. Common echographic findings were noted in ten of these patients, and included: (1) a solid, high-reflective peripheral mass, (2) a vitreous band or membranes extending between the posterior pole and the mass, and (3) a traction retinal detachment or fold from the posterior pole to the mass. These findings were present in patients presenting with leukocoria or endophthalmitis, as well as in patients in whom the peripheral nematode lesion could be visualized clinically. In combination with the history, clinical examination, and enzyme-linked immunosorbent assay (ELISA), standardized echography may be useful in establishing the diagnosis of ocular toxocariasis in cases of leukocoria in which nematode endophthalmitis is suspected.
眼内炎、局限性后极肉芽肿或周边肉芽肿。作者使用标准化超声检查法对11例表现为上述综合征之一的弓蛔虫病患者进行了研究。其中10例患者有常见的超声检查结果，包括：（1）一个实性、高反射性的周边肿块；（2）一条玻璃体带或膜，在眼球后极与肿块之间延伸；（3）一个从眼球后极至肿块的牵拉性视网膜脱离或皱襞。这些表现见于有白瞳症或眼内炎的患者，以及临床上能看到周边线虫病变的患者。结合病史、临床检查和酶联免疫吸附测定（ELISA），标准化超声检查法在怀疑有线虫性眼内炎的白瞳症病例中，可能有助于眼弓蛔虫病的诊断。
