Combine intravitreal bevacizumab with Nd:YAG laser hyaloidotomy for valsalva pre-macular haemorrhage and observe the internal limiting membrane changes:a spectralis study

Abstract

Valsalva retinopathy was described as a particular form of retinopathy, pre-retinal and subinternal limiting membrane haemorrhages in nature that rarely may break through and become subhyloid or intravitreal, secondary to a sudden increase in intrathoracic pressure. We reported a new way that Nd:YAG laser for ILM hyaloidotomy in order to drain the sub-ILM blood into vitreous cavity combined with intravitreal bevacizumab to improve the absorption of blood. Therapeutic alliance make significant outcome, protecting vision in time. We used spectralis OCT to observe sub-ILM mix cells and special ILM structure in this lesion for the first time, as the spectralis OCT can reach histology level imagination.
