Abstract
- Aims:To study the efficacy of verteporfin photodynamic therapy (VPDT) retrospectively in the treatment of idiopathic subfoveal choroidal neovascularization (ICNV) in an Asian population in correlation with number of treatments and age at treatment. This is the first report to compare the efficacy between single and multiple treatments.Methods:VPDT was administered according to protocol to 45 eyes in 45 patients aged 18–55 years diagnosed with active subfoveal ICNV between September 2003 and December 2005. In total 28 patients received a single VPDT treatment and the remaining 17 received multiple treatments. Collected measurements of visual acuity (VA) were plotted on a time-course model, and later dichotomized by age (18–45 vs46–55 years).Results:The 28 patients receiving a single VPDT treatment showed significant improvement in VA at 3-month follow-up. The 17 patients, who did not show improvement after the first treatment, received multiple VPDT treatments. Those patients showed an even clearer trend in VA improvement although significance was detected only at the 24th month. All patients showed a significant improvement in mean VA of 0.46 logMAR (P<0.01 compared to baseline) by the end of the 24-month observation period, although VPDT treatment for subfoveal ICNV appears to stabilize vision more rapidly in younger patients.Conclusions:ICNV patients who did not benefit from single VPDT treatments could receive multiple treatments, and showed a more significant improvement in visual acuity. These results are the first of their kind in ICNV treatment.Eye (2009) 23, 314–319; doi:10.1038/sj.eye.6703073; published online 18 January 2008 [ABSTRACT FROM AUTHOR]
