Purpose: To evaluate photodynamic therapy (PDT) with verteporfin along with intravitreal triamcinolone acetonide (IVTA) in the treatment of neovascular age-related macular degeneration (AMD).Materials and Methods: This prospective interventional case series included 23 patients (23 eyes) of choroidal neovascularization due to neovascular AMD who were treated with PDT with verteporfin followed by an injection of 4 mg IVTA. The main outcome measures were visual acuity (VA), contrast sensitivity, retreatment frequency with PDT (and triamcinolone) and frequency of side-effects.Results: Twenty-three eyes underwent PDT with verteporfin followed by IVTA one week later. All patients were followed up for one year. Initial VA ranged from 20/32 to 20/800 and final VA ranged from 20/40 to 20/500 at the end of 12 months. VA stabilized (that is loss/gain < 2 lines) in 19 (82%) eyes. Contrast sensitivity also improved in 16/23 eyes (70%). Lesion type and patient's age had no influence on the outcome, but baseline VA had a borderline statistically significant effect (P =0.059). Six eyes (27%) had an increase in intraocular pressure that required therapy. There were no cases of endophthalmitis, but four eyes (18%) developed significant cataract that required surgery during the follow-up period.Conclusion: The combination of PDT along with IVTA improves contrast sensitivity and stabilizes vision during one-year follow-up.
