To describe a novel surgical technique for the removal of a live intravitreal nematode.
We describe the surgical management of a 35-year-old man with a live intravitreal nematode in his left eye. A 23-gauge pars plana limited core vitrectomy was performed to release the nematode from the surrounding vitreous strands. After creating a peritomy, a 20-gauge full thickness sclerotomy was created with a microvitreoretinal blade. The tip of a 20-gauge angiocath needle was cut obliquely and inserted through the sclerotomy. The external portion of the needle was attached to the viscous fluid extraction tubing for the Constellation vitrectomy machine (Alcon). Gentle aspiration pulled the nematode into the angiocath. The nematode was transferred to a syringe for parasitologic evaluation.
The novel surgical technique described allows for aspiration of an intravitreal nematode in a controlled fashion. This technique can be used to manage this rare, but visually significant condition.
描述一种用于取出活体内玻璃体线虫的新型手术技术。
我们描述了一名35岁左眼有活体内玻璃体线虫男性患者的手术治疗情况。进行了23G经平坦部有限核心玻璃体切除术,以将线虫从周围的玻璃体条索中释放出来。在制作结膜切开术后,用微型玻璃体视网膜刀制作了一个20G全层巩膜切开术。将20G血管造影导管针的尖端斜切,然后通过巩膜切开术插入。针的外部连接到用于Constellation玻璃体切除机(爱尔康)的粘性流体提取管。轻柔抽吸将线虫吸入血管造影导管。线虫被转移到注射器中进行寄生虫学评估。
所描述的新型手术技术允许以可控方式抽吸眼内线虫。该技术可用于处理这种罕见但对视功能有重要影响的情况。
