ABSTRACT
Purpose:
To investigate the efficacy of half-dose photodynamic therapy (PDT) for treating symptomatic serous non-neovascular pigment epithelial detachment (PED) and to identify factors associated with treatment outcome. Patients andmethods:
This is a single-institute retrospective case series involving 12 eyes of 12 consecutive patients with serous non-neovascular PED who received half-dose PDT. We investigated the temporal change in best-corrected visual acuity (BCVA), the anatomic outcomes of PED, including recurrence, central choroidal thickness (CCT), and also choroidal thickness as a possible factor associated with treatment outcome.Results:
At baseline, mean logMAR BCVA was 0.06 (range Snellen equivalent 6/20 to 24/20); 24 months later, it was 0.01 (Snellen equivalent 6/20 to 24/20; P=0.3). At 3 months, PED had completely flattened in 8, decreased in height in 2, and remained unchanged in 2. The CCT in eyes with PED was 410 µm and thicker than that in fellow eyes (290 µm, P<0.0001). Recurrence was noted in 2 within 12 months after treatment. Eyes in which the choroidal thickness with a baseline CCT >350µm or a 100 µm difference in CCT responded favorably to half-dose PDT (P=0.02).Conclusion:
Half-dose PDT is effective in patients with non-neovascular PED. Thicker choroid and some difference in CCT between affected and fellow eye might be a good index for predicting the efficacy of this treatment.
