Abstract

PURPOSE : Premacular subhyaloid hemorrhage is usually a benign condition that generally improves spontaneously and rarely causes visual loss. However, because premacular hemorrhage may be associated with permanent macular changes before it spontaneously resolves, Nd: YAG laser posterior hyaloidotomy may be indicated in selected cases. This study was undertaken to assess an alternative, Nd: YAG laser treatment, in treating this type of hemorrhage. MATERIAL-METOD : This study was performed between 1996 and 1999. Six patients had a circumscribed premacular hemorrhage in one eye and who were treated with the Nd: YAG laser to drain the entrapped blood into the vitreous cavity. The size of the hemorrhage expressed in disc diameters. RESULTS : The mean size of the pretreatment hemorrhage was 5.7 (3.5-8.0) disc diameters. The visual acuities of all cases before laser treatment was at the level of hand motions. In all eyes, following Nd:YAG laser treatment, the hemorrhage instantaneously was drained into the vitreous cavity, resulting in a rapid improvement of vision. Complete drainage of the premacular hemorrhage was occured in within one week. Visual acuity improved dramatically within one week. The mean period of follow-up was 26.3 (7-42) months. No retinal damage or rebleeding occured due to the laser treatment, any vitrectomy was not required in any eye. CONCLUSION : Nd:YAG laser posterior hyaloidotomy may be useful in drainage of premacular hemorrhage into the vitreous cavity in selected cases. To establish this treatment as a routine procedure, a randomized trial is needed to evaluate observation, primary vitrectomy, and Nd:YAG laser treatment of premacular hemorrhage.

Özet

AMAÇ : Premaküler subhiyaloid hemoraji (PSH) genellikle zararsız bir durum olup, çoğunlukla kendiliğinden düzelmekte ve nadiren görme kaybına yol açmaktadır. Ancak, PSH kendiliğinden düzelirken, bazı olgularda kalıcı maküler değişikliklere neden olmaktadır. Bu nedenle, bu tür seçilmiş olgularda Nd: YAG laser posterior hiyaloidotomi (NYLPH) ile kanın drenajı yararlı olmaktadır. YÖNTEM : Bu çalışma 1996-1999 tarihleri arasında, bir gözünde değişik nedenlerle PSH olan 2'si kadın, 4'ü erkek toplam 6 hasta üzerinde gerçekleştirilmiştir. PSH'nin büyüklüğü optik disk çapı olarak ifade edilmiş ve bu olgularda PSH'nin tedavisi amacıyla NYLPH işlemi uygulanmıştır. BULGULAR : Tedavi öncesi, görme keskinliği tüm olgularda el hareketleri seviyesinde olup, PSH'nin büyüklüğü ortalama 5.7 (3.5-8.0) disk çapı olarak ölçülmüştür. NYLPH'yi takiben, PSH vitreusa hızla drene olmaya başlamış ve komplet drenaj bir haftada tamamlanmış olup, bu esnada görmede dramatik bir artış gözlenmiştir. Olgular ortalama 26.3 (6-42) ay süresince izlenmiş olup, hiçbir olguda lasere bağlı kanama ve retinal hasar gözlenmemiş; hiçbir olguda vitrektomi gerekmemiştir. SONUÇ : NYLPH, seçilmiş olgularda PSH'nin vitreusa trenajını sağlayarak yararlı olabilmekle birlikte, bu işlemin PSH tedavisinde rutin bir yöntem olabilmesi için, hastaların izlenimleri ve primer vitrektomiyi de içeren randomize çalışmaların yapılması gerekmektedir.
