Background  

To evaluate the efficacy of combined photodynamic therapy (PDT) and intravitreal bevacizumab injection in eyes with a serous pigment epithelial detachment (PED) associated with age-related macular degeneration (AMD).

Methods  

Twenty-two eyes with a serous PED exceeding two disc areas associated with AMD with choroidal vascular abnormalities [choroidal neovascularization (n = 10), polypoidal choroidal vasculopathy (n = 9), and retinal angiomatous proliferation (n = 3)] received combined PDT and intravitreal bevacizumab, and were followed about every 6 weeks for more than 1 year. Additional treatments were given for residual or recurrent lesions. The main outcome measures were changes in the PED height measured by optical coherence tomography, and the best-corrected visual acuity.

Results  

After one treatment, the PED resolved in 12 eyes (55%) and the PED decreased in ten eyes (45%). There was no recurrence in eight (36%) eyes; however, PED recurred in 14 eyes. At 1 year, the average PED height decreased to 413 microns from the baseline 751 microns (p < 0.001). Twenty eyes (91%) had improved or stabilized vision; two eyes had decreased vision due to a retinal pigment epithelial tear and subretinal hemorrhage.

Conclusions  

Combined PDT and intravitreal bevacizumab may decrease the PED height and stabilize visual acuity at 1 year.
