Treatment of herpes zoster related corneal neovascularisation and lipid keratopathy by photodynamic therapy

Traditionally, photodynamic therapy (PDT) has been used to treat choroidal neovascularisation. More recently, its use in corneal neovascularisation has provided promising clinical results. The major advantage of PDT is that it is minimally invasive, resulting in closure of the neovascular network without damaging the surrounding healthy tissue. This report describes the positive results of PDT, clinically and microstructurally, as imaged by in vivo confocal microscopy, for treating corneal neovascularisation with lipid keratopathy, secondary to herpes zoster infection.
