BACKGROUND
The authors report a case of posterior internal ophthalmomyiasis causing vitreous haemorrhage and retinal detachment after uncomplicated cataract extraction.
CASE REPORT
The patient suffered an abrupt vitreous haemorrhage 9 days after ECCE and posterior chamber IOL implantation. After 2 months the haemorrhage did not clear up and a retinal detachment arose. The patient underwent encircling scleral buckle, pars plana vitrectomy and fluid-gas exchange. In course of intervention the surgeon removed from the vitreous chamber a 14-mm-long round worm subsequently identified as a dipterous larva of the Sarcophagidae family.
DISCUSSION
The patient showed no sign of subretinal tracking or retinal breaks or holes. The sclerocorneal surgical wound seems the most likely site of entrance of the parasite, and this would then be the first reported case of myiasis with no RPE tracking.
背景
作者报告了1例在无并发症的白内障摘除术后发生眼内后部蝇蛆病并导致玻璃体出血和视网膜脱离的病例。
病例报告
患者在超声乳化白内障吸除术及后房型人工晶状体植入术后9天突然发生玻璃体出血。2个月后出血仍未消退，并出现视网膜脱离。患者接受了环扎巩膜扣带术、玻璃体切除术及液-气交换术。在手术过程中，外科医生从玻璃体腔中取出了一条14毫米长的蛔虫，随后鉴定为麻蝇科的双翅目幼虫。
讨论
患者未表现出视网膜下追踪或视网膜裂孔或破洞的迹象。巩膜角膜手术切口似乎是寄生虫最可能的侵入部位，这将是首例无视网膜色素上皮层追踪的蝇蛆病病例报告。
