Is there any relationship between photodynamic therapy for exudative age-related macular degeneration and choroidal neovascolarization recurrence?
The authors failed to identify angiographic signs helpful to predict the risk of CNV persistence or recurrence. PDT leaves minor but persistent changes in the choroidal vasculature within the treatment area. In some cases, the recurrent CNV seems to be related to the laser spot of the PDT.
In this retrospective analysis of a large PCI database, the 'heparins crossover' during PCI was not associated with increased bleeding risk.
