Yag laser membranotomy and pneumatic displacement for premacular haemorrhage secondary to valsalva retinopathy: The inverse drainage technique

Purpose: To describe an alternative mode of treatment for premacular haemorrhage secondary to valsalva retinopathy with inferior borders over the fovea. Method: Interventional case series involving 3 patients with premacular haemorrhage due to valsalva retinopathy with inferior margins over the fovea. All were treated with Nd:YAG membranotomy to the superior border of the haemorrhage with inverse drainage facilitated by intravitreal injection of sulfur hexafluoride (SF6) and 24hrs of prone positioning. Results: Clearing of the premacular haemorrhage and restoration of normal vision was achieved within a week in the three eyes treated. Conclusion: Nd:YAG membranotomy combined with intravitreal injection of SF6 may be an alternative, safe and effective method for treating premacular haemorrhage with an inferior border overlying the fovea.
