title: Photodynamic treatment of a secondary vasoproliferative tumour associated with sector retinitis pigmentosa and Usher syndrome type I.
abstract: Vasoproliferative tumours may be primary or secondary and present with severe exudation leading to marked visual loss. We describe a 47-year-old man with unilateral secondary vasoproliferative tumour associated with sector retinitis pigmentosa and Usher I syndrome who was successfully treated with a single session of photodynamic treatment. Standard treatment protocol was used except that the treatment duration was doubled. A year after the treatment, the angioma-like tumour vanished and exudation was dramatically reduced. Photodynamic therapy seems to be a minimally invasive and safe technique in eyes with secondary vasoproliferative tumours.
