Photodynamic monotherapy or combination treatment with intravitreal triamcinolone acetonide, bevacizumab or ranibizumab for choroidal neovascularization associated with pathological myopia

Indian J Ophthalmol. 2011 May-Jun;59(3):242-6. doi: 10.4103/0301-4738.81049.

Abstract

This retrospective, interventional case series analyses treatment outcomes in eyes with choroidal neovascularization (CNV) secondary to pathological myopia, managed with photodynamic therapy, (PDT), (Group 1, N = 11), PDT and intravitreal triamcinolone acetonide (4 mg/0.1ml) (Group 2, N = 3), PDT and intravitreal anti-vascular endothelial growth factor (anti-VEGF) bevacizumab 1.25 mg/0.05 ml, ranibizumab 0.5 mg/0.05 ml and reduced-fluence PDT and intravitreal ranibizumab 0.5 mg/0.05 ml (Group 3, N=12). All the patients underwent PDT. Intravitreal injections were repeated as required. SPSS 14 software was used to evaluate the data. Wilcoxon signed ranks test was used to evaluate pre- and post-treatment vision. The Kruskal-Wallis test was used for comparison between the groups. All the groups were statistically comparable. All the eyes showed complete regression of CNV, with a minimum follow-up of six months. All groups had visual improvement; significantly in Group 3 ( p = 0.003). Combination PDT with anti-VEGF agents appeared to be efficacious in eyes with myopic CNV. However, a larger study with a longer follow-up is required to validate these results.
