Vitreoretinal surgical diseases in children are challenging because of the complex features of the vitreous, retina, and the interface between them. Posterior vitreous detachment is a crucial step during vitrectomy. To date, pharmacologic vitreolysis that liquefies the vitreous and disrupts the posterior hyaloid attachment to the retina has been studied. However, there are reports of unexplained adverse effects. We describe a case performed with a reproducible, safe and time-saving technique using a commercially available flexible loop for posterior vitreous detachment induction in a pediatric patient.
A 10-year-old boy with previously treated retinopathy of prematurity undergoes a 25-gauge pars plana vitrectomy for retina detachment repair. To achieve a posterior vitreous detachment, a flexible loop was used to grasp and pick the vitreoretinal interface around the optic nerve for dissection of the posterior hyaloid, followed by aspiration and cutting with the vitrectomy probe to complete the vitrectomy.
At 3 months follow-up, total retinal reattachment was observed. The patient's vision improved from 20/400 to 20/150.
Posterior vitreous detachment induction with a flexible loop instead of pharmacologic vitreolysis seems a promising tool as demonstrated in this clinical case. Further studies to demonstrate long-term safety and anatomical results are needed.
儿童的玻璃体视网膜手术疾病具有挑战性,因为玻璃体、视网膜及其界面具有复杂的特征。玻璃体后脱离是玻璃体切除术的关键步骤。迄今为止,已经研究了通过药理学方法使玻璃体液化并破坏后玻璃体与视网膜的附着的方法。但是,有报道称存在无法解释的不良影响。我们描述了一种使用市售的柔性环在儿科患者中进行的可重复,安全且省时的技术,用于诱导玻璃体后脱离的案例。
一名 10 岁男孩曾接受过早产儿视网膜病变的治疗,因视网膜脱离修复而行 25G 经睫状体平坦部玻璃体切除术。为了实现玻璃体后脱离,使用柔性环抓住并挑取视神经周围的玻璃体视网膜界面,以分离后玻璃体,然后用玻璃体切割探针抽吸和切割以完成玻璃体切除术。
在 3 个月的随访中,观察到视网膜完全复位。患者的视力从 20/400 提高到 20/150。
与药理学方法相比,使用柔性环进行玻璃体后脱离诱导似乎是一种有前途的工具,正如本临床病例所示。需要进一步的研究来证明其长期安全性和解剖学结果。
