چکیده
PURPOSE 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. DESIGN Nonrandomized, prospective, interventional, controlled case series. METHODS 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. RESULTS 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. CONCLUSION 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.

Photodisruptive Nd:Yag laser in the management of premacular subhyaloid hemorrhage.
PURPOSE Premacular subhyaloid hemorrhage is usually a benign condition that generally improves spontaneously and rarely causes visual loss. However, because the hemorrhage may cause permanent macular changes before it resolves, Nd:YAG laser posterior hyaloidotomy may be indicated in selected cases. This study investigated the effects of drainage of premacular subhyaloid hemorrhage into the vitr...
متن کاملNd:YAG Laser Hyaloidotomy for the Treatment of Acute Subhyaloid Hemorrhage: A Comparison of Two Cases
INTRODUCTION Subhyaloid hemorrhage, whether spontaneous or in the context of a Valsalva maneuver, can lead to an acute decrease in vision when located in the premacular region. Nd:YAG laser hyaloidotomy (NYLH) is a minimally invasive treatment option. METHODS We examined two different clinical courses based on two case reports of NYLH. One case report described a 52-year-old female patient wh...
