Long-term results of Nd:YAG laser treatment for premacular subhyaloid haemorrhage owing to Valsalva retinopathy.

摘要

AimsValsalva retinopathy produces sudden visual loss, which may be prolonged if untreated. Nd:YAG laser enables rapid diffusion of premacular subhyaloid haemorrhage. This study was performed to assess the long-term results and safety of Nd:YAG laser treatment in cases with Valsalva retinopathy.MethodsSixteen patients had Nd:YAG laser treatment to drain premacular haemorrhage. The follow-up period was 24 months.ResultsAll eyes had marked clearing of haemorrhage and immediate improvement of vision following laser treatment. In 14 eyes visual acuity improved to 20/20 level at the end of the first week and the remaining two patients achieved 20/20 level within 1 month. No patient had evidence of retinal or choroidal damage.ConclusionNd:YAG laser treatment for Valsalva retinopathy is an effective, non-invasive, and safe procedure for patients with a premacular subhyaloid haemorrhage larger than 3 disc diameter and no longer than 3 weeks of duration.Eye (2008) 22, 214-218; doi:10.1038/sj.eye.6702574; published online 1 September 2006.
