    Abstract:
    PURPOSE: To describe the safety and efficacy of intravitreal tissue plasminogen activator (tPA) and sulfur hexafluoride (SF6) gas with sequential photodynamic therapy (PDT) in the management of submacular hemorrhage (SMH) associated with macular degeneration (MD). METHODS: Consecutive case series of five patients presenting with acute SMH from neovascular MD between May 2004 and January 2006 in a UK Eye Centre. Duration of visual loss was less than 7 weeks. Treatment involved intravitreal injections of tPA, SF6 gas to achieve pneumatic displacement of SMH, and 24 hours prone posturing. Displacement of SMH was assessed by digital photography, and choroidal neovascularization (CNV) was reclassified using angiography. PDT was applied when indicated within 1 to 12 days postoperatively. RESULTS: Adequate displacement of SMH allowed visualization of CNV within 24 hours in three of five patients. One patient with large SMH of 7 weeks duration had partial displacement of SMH. Three patients were reclassified with classic CNV after tPA-SF6 injection, and successfully underwent PDT. CONCLUSIONS: Intravitreal tPA and SF6 assisted pneumatic displacement of SMH is a safe and effective intervention. This technique facilitates more accurate angiographic classification of CNV. PDT may be sequentially and rapidly applied as early as 1 day after injections. The technique may be offered to patients with neovascular MD presenting with acute SMH.
