Abstract

BACKGROUND

A measurable burden to the emergency ophthalmology department is represented by ocular trauma in pediatric patients. Traumatic cataracts still result in visual disability despite great advancements in diagnostic and treatment methods. Cataract surgery with intraocular lens (IOL) implantation aids in the improvement of visual acuity in such cases. Duration of trauma is an important prognostic factor for recovery of visual acuity before amblyopia sets in young patients with penetrating ocular injury.

PURPOSE

This video deals with the management of a case of partially absorbed traumatic cataract in a scenario of an old and neglected penetrating injury. This case had a corneal scar, ruptured anterior lens capsule, and posterior synechiae formation between the posterior pigmented epithelium of the iris and the lens capsule.

SYNOPSIS

In a case of penetrating ocular injury, one should always suspect violation of posterior lens capsule, weakened or broken zonules and retained intraocular foreign body. In this case, a circular capsulorhexis is difficult to attain. After staining the capsule with trypan blue dye, viscoelastic substance is instilled in the anterior chamber to have good control over the rhexis and to avoid rhexis run out. In case the rhexis runs off to the equator, a pair of Vannas scissors is used to cut the extended flap. The cataract is partially absorbed, white and soft in nature and is easily mobilized from the bag and eaten up via phacoaspiration. Before implantation of posterior chamber intraocular lens (PCIOL) in the sulcus, posterior synechiae are released by swiping a cyclodialysis spatula in the sulcus area. Visual axis is cleared by giving nicks in the posterior capsule to remove the central dense posterior plaque. Automated anterior vitrectomy is done and a three-piece PCIOL is implanted safely in the ciliary sulcus. Retained viscoelastic substance is washed, intracameral antibiotic is instilled, and the anterior chamber is subsequently formed via stromal wound hydration.

HIGHLIGHTS

Through this video, we tried to show how one should proceed with phacoaspiration with intraocular lens implantation in a case of traumatic cataract post penetrating injury in a sequential manner.

摘要

背景

儿科患者的眼部创伤给急诊眼科带来了可衡量的负担。尽管在诊断和治疗方法上取得了很大进展,但外伤性白内障仍然导致视力障碍。在这种情况下,白内障手术联合人工晶状体(IOL)植入有助于提高视力。对于穿透性眼外伤的年轻患者,在弱视发生之前,外伤持续时间是影响视力恢复的一个重要预后因素。

目的

本视频介绍了一例陈旧性穿透性眼外伤所致部分吸收性外伤性白内障的处理方法。该病例存在角膜瘢痕、前晶状体囊破裂和虹膜后色素上皮与晶状体囊之间的后粘连。

概要

在穿透性眼外伤的情况下,应始终怀疑后晶状体囊破裂、悬韧带变弱或断裂以及眼内异物残留。在这种情况下,圆形撕囊较难完成。用台盼蓝染料染色囊膜后,在前房内注入黏弹剂,以良好控制撕囊口,避免撕囊口跑向赤道部。如果撕囊口跑向赤道部,可以使用一对 Vannas 剪刀来切割延长瓣。白内障部分吸收,呈白色和柔软,很容易从囊袋中游离出来,并通过超声乳化吸出。在将后房人工晶状体(PCIOL)植入巩膜槽之前,通过在巩膜槽区域滑动环扎刀来松解后粘连。在后囊中央致密后斑处做切口以清除视轴,随后行自动前段玻璃体切除术。安全地将三件式 PCIOL 植入睫状沟。冲洗掉残留的黏弹剂,眼内注入抗生素,然后通过基质伤口水化形成前房。

要点

通过本视频,我们试图展示在陈旧性穿透性眼外伤后外伤性白内障的情况下,如何按照顺序进行白内障超声乳化吸出联合人工晶状体植入。
