广州管圆线虫,通常被称为鼠肺虫,主要在亚洲发现,太平洋盆地,加勒比海地区,但也是夏威夷特有的,尤其是在夏威夷岛.眼部血管圆线虫病是一种罕见的,但以前报道过的与永久性视力丧失相关的并发症。这是美国首例涉及视网膜或眼后段的眼血管圆线虫病。一名来自芝加哥的24岁男性参观了夏威夷岛,他在农场工作,吃素食。当他回到芝加哥时,他生病并因嗜酸性粒细胞性脑膜炎住院。一个月后,他出现了视网膜脱离,需要进行手术修复,包括玻璃体切割术。在手术期间视网膜重新附着的过程中,在视网膜下间隙中发现了一种活动线虫。内激光探针固定并杀死了线虫,随后通过巩膜切开术将其取出。包括视网膜切开术部位在内的所有视网膜孔周围都有热疤痕,以稳定视网膜,注入全氟丙烷气体以实现临时填塞。此后,患者的脑脊液恢复为广州管圆线虫抗体阳性。在长期随访期间,由于复发性视网膜脱离,患者最终丧失了患眼的所有视力.此例眼血管圆线虫病证明了从流行地区获取旅行史的重要性,知道患嗜酸性粒细胞性脑膜炎的风险,并了解在涉及视网膜的情况下永久性视力丧失的风险。
Angiostrongylus cantonensis, commonly known as the rat lungworm, is mostly found in Asia, the Pacific Basin, and the Caribbean, but is also endemic in Hawai\'i, especially on the Island of Hawai\'i. Ocular angiostrongyliasis is an uncommon but previously reported complication associated with permanent vision loss. This is the first reported
case of ocular angiostrongyliasis involving the retina or posterior segment of the eye in the US. A 24-year-old male from Chicago visited the Island of Hawai\'i, where he worked on a farm and ate a vegetarian diet. When he returned to Chicago, he became sick and was hospitalized for eosinophilic meningitis. One month later, he developed a retinal detachment which required surgical repair involving a pars plana vitrectomy. During the reattachment of the retina during surgery, a live motile was identified nematode in the subretinal space. An endolaser probe immobilized and killed the nematode, and it was subsequently extracted through the sclerotomy. Thermal scars around all retinal holes including the retinotomy site were made to stabilize the retina, and perfluoropropane gas was injected to achieve temporary tamponade. Thereafter, the patient\'s cerebrospinal fluid returned positive for angiostrongylus cantonensis antibodies. During extended follow-up, the patient eventually lost all vision in the affected eye due to recurrent retinal detachment. This
case of ocular angiostrongyliasis demonstrates the importance of obtaining travel history from endemic areas, knowing the risk of developing eosinophilic meningitis, and understanding the risk of permanent vision loss in cases involving the retina.
