. Purpose: To identify characteristic morphological changes of the retina over time and the association with visual function after combined photodynamic therapy (PDT) and intravitreal triamcinolone (IVTA). Methods: In this retrospective study, 40 patients (40 eyes) were treated with PDT and same‐day IVTA. Optical coherence tomography (OCT), fluorescein angiography (FA) and evaluation of distance visual acuity (VA) were performed. The anatomical changes within intra‐ and subretinal compartments and their detailed analysis and grading were the main outcome measures. Results: Intraretinal fluid (IRF) and subretinal fluid (SRF) by OCT decreased until 3 months ( p < 0.01). At month 3, intraretinal cystoid spaces (ICS) had resolved or decreased in 84% of eyes, SRF in 58% and pigment epithelial detachment (PED) in 50%. Mean best‐corrected VA (BCVA) improved significantly at month 1 (p < 0.01). Mean central retinal thickness (CRT) increased from 334 μm at baseline to 439 μm at day 1 (p = 0.03) before decreasing to 286 μm at day 7 (p = 0.06), 233 μm at month 1 (p = 0.001) and 255 μm at month 3 (p = 0.001). Conclusion: Combined verteporfin/IVTA therapy induces distinct time‐related effects on the retina within the different intra‐ and subretinal compartments.
