This study aimed to evaluate the benefits of Nd:YAG laser posterior hyaloidotomy as a method allowing rapid drainage of subhyaloid hemorrhage into the vitreous gel.
Nonrandomized, prospective, interventional, controlled case series.
Nd:YAG laser posterior hyaloidotomy was performed in four eyes of three patients with premacular subhyaloid hemorrhage. The etiologies were bleeding tendency, proliferative diabetic retinopathy, and idiopathic. Four eyes of four patients with premacular subhyaloid hemorrhage were managed conservatively. The etiologies were proliferative diabetic retinopathy and Valsalva retinopathy.
A rapid resolution of subhyaloid hemorrhage with improvement of visual acuity was achieved in all patients treated with Nd:YAG laser posterior hyaloidotomy, without evidence of damage to the retina or choroid. With regard to the conservatively managed eyes, there was a tendency towards slow spontaneous absorption of hemorrhage during the follow-up period.
Nd:YAG laser posterior hyaloidotomy was a safe and effective procedure for rapid resolution of premacular subhyaloid hemorrhage, allowing rapid restoration of visual acuity, visualization of the underlying retina, expedited access for macular photocoagulation and avoidance of vitrectomy.
本研究旨在评估钕钇铝石榴石(Nd:YAG)激光后玻璃体膜切开术作为一种能使黄斑下出血快速引流至玻璃体凝胶中的方法的益处。
非随机、前瞻性、干预性、对照病例系列。
对3例黄斑前黄斑下出血患者的4只眼进行Nd:YAG激光后玻璃体膜切开术。病因分别为出血倾向、增殖性糖尿病视网膜病变和特发性。对4例黄斑前黄斑下出血患者的4只眼进行保守治疗。病因分别为增殖性糖尿病视网膜病变和瓦尔萨尔瓦视网膜病变。
所有接受Nd:YAG激光后玻璃体膜切开术治疗的患者黄斑下出血均迅速消退,视力提高,且无视网膜或脉络膜损伤的迹象。对于保守治疗的眼睛,在随访期间有出血缓慢自发吸收的趋势。
Nd:YAG激光后玻璃体膜切开术是一种安全有效的方法,可快速消除黄斑前黄斑下出血,使视力迅速恢复,能看清视网膜下层,便于进行黄斑光凝,并避免了玻璃体切除术。
