Summary: | Combined photodynamic therapy (PDT) and intravitreal injection of triamcinolone acetonide is a new option in the treatment of the neovascular form of age-related macular degeneration. With the aim of increasing safety and efficacy we examined whether it is possible to administer the intravitreal injection prior to PDT.
Patients with retinal angiomatous proliferation, who have an unfavourable prognosis when treated with PDT alone, were recruited to this study. Intravitreal injection of triamcinolone acetonide was applied 1 day before PDT. Distance acuity testing, retinal thickness measurement and fluorescein angiography were performed before treatment and 6 weeks and 3 months thereafter.
Twenty-five patients were included: 18 were female, 7 male. Their mean age was 79 years. The distance acuity was 68 letters before treatment and at the follow-up examinations. The retinal thickness decreased significantly from mean 470.8 microm to 335.4 microm at week 6 and 360.8 microm at month 3. At month 3, 48% showed signs of activity in the fluorescein angiography needing retreatment. Visualisation of the fundus was not reduced by the triamcinolone crystals.
PDT was possible without difficulty after intravitreal injection of triamcinolone acetonide. Stabilisation of the visual acuity was possible, although only eyes with retinal angiomatous proliferation were included. |
