Nd:YAG laser therapy for premacular subhyaloid haemorrhage

Objective & Hypothesis:Nd:YAG laser posterior hyaloidotomy was intervened to two male patients with acute visual loss due to premacular subhyaloid haemorrhage between 2005 and 2006.

📊

Key Findings & Data:Before treatment, visual acuities were hand motion for the patients aged 71 years old and 0.6 for the other patient aged 52 years old who had parafoveal haemorrhage.

💡

Conclusion & Impact:It causes rapid resolution of premacular subhyaloid haemorrhage, and thus decrease the need for vitreoretinal surgery.

Abstract

Nd:YAG laser posterior hyaloidotomy was intervened to two male patients with acute visual loss due to premacular subhyaloid haemorrhage between 2005 and 2006. Their etiology, visual acuity, fundus photographs and prognosis were analyzed. Before treatment, visual acuities were hand motion for the patients aged 71 years old and 0.6 for the other patient aged 52 years old who had parafoveal haemorrhage. The etiologies of haemorrhage were macroaneurysm and proliferative diabetic retinopathy, respectively. After Nd: YAG laser hyaloidotomy, the hemorrhages drained into the vitreous cavity and complete resorbtion was observed in both patients three weeks later. The mean follow up time was 6 months. In the last examination, their visual acuities reached to 0.3 and 0.7, respectively, and they had no any evidence of damage due to laser application. Nd:YAG laser hyaloidotomy is a easy, safe and effective procedure for premacular subhyaloid hemorrhages. It causes rapid resolution of premacular subhyaloid haemorrhage, and thus decrease the need for vitreoretinal surgery.

Özet

2005-2006 yılları arasında premaküler subhiyaloid hemoraji nedeniyle ani görme kaybı gelişen iki erkek hastaya Nd:YAG lazer ile arka hiyaloidotomi yapıldı. Hastaların etiyolojileri, görme keskinlikleri, fundus fotoğrafları, prognozları değerlendirildi. Tedavi uygulanmadan önceki görme keskinlikleri 71 yaşındaki hastada el hareketi düzeyinde, diğer 52 yaşındaki parafoveal hemorajili hastada 0.6 düzeyinde idi. Olgulardaki kanama nedenleri, sırasıyla anevrizma ve proliferatif diabetik retinopatiydi. Hastalarda Nd:YAG lazer ile hiyaloidotomi yapıldıktan sonra kanın rezorbsiyonu üç hafta içinde tamamladı. Ortalama takip süreleri 6 ay olan hastaların görme düzeyleri son kontrollerinde sırasıyla 0.3 ve 0.7’ye yükseldi. Takip süresince hastalarda lazer uygulamasına bağlı her hangi bir retinal hasar bulgu gözlenmedi. Kolay, güvenilir ve etkili bir metot olan Nd:YAG lazer hiyaloidotomi işlemi premaküler subhiyaloidal hemorajinin hızlı bir biçimde rezolüsyonuna neden olarak vitreoretinal cerrahiye olan gereksinimi azaltmaktadır.
