PURPOSE: To evaluate the efficacy of intravitreal injection of bevacizumab combined with photodynamic therapy (PDT) for the treatment of occult choroidal neovascularization (CNV) associated with serous pigment epithelium detachment (s-PED) due to age-related macular degeneration (AMD).

METHODS: In this retrospective study, six patients (six eyes) with subfoveal occult CNV associated with s-PED due to AMD were treated with intravitreal bevacizumab combined with PDT. All patients were treated at baseline with PDT followed by intravitreal bevacizumab 1.25 mg 1 hour later. Afterwards, according to the findings of optical coherence tomography and fluorescein angiography, repeat bevacizumab injections were given, if necessary, monthly for three doses followed by further doses every 3 months. PDT was repeated every 3 months according to the same criteria. Follow-up time was 9 months.

RESULTS: All patients completed their treatment during the first 3 months from baseline. Best-corrected visual acuity (BCVA) improved or remained stable related to the baseline values in all patients at the end of the follow-up time. Mean BCVA improved from 20/67 to 20/42. S-PED and subretinal fluid decreased or disappeared. The mean central 1-mm retinal thickness was reduced from baseline value for the 9-month follow-up period by 128 microm.

CONCLUSION: Intravitreal bevacizumab combined with PDT seems to be a promising treatment with good functional and anatomical results for occult CNV associated with s-PED due to AMD.
