- Abstract: PURPOSE: The goal of the present research was to study post-treatment changes in polypoidal choroidal vasculopathy (PCV) shown by optical coherence tomography (OCT). METHODS: The study included 12 patients with naive PCV. Photodynamic therapy and 3 consecutive intravitreal bevacizumab injections at 6-week intervals were given. Best corrected visual acuity, subretinal fluid (SRF), pigment epithelium detachment (PED), central macular thickness (CMT), and total macular volume (TMV) were measured before and after treatment as assessed by Stratus OCT3. RESULTS: After treatment, the SRF height decreased earlier than the PED height. The SRF diameter decreased with statistical significance. However, the PED diameter did not show a statistically significant improvement, persisting at pre-treatment levels. Both CMT and TMV decreased significantly after treatment. CONCLUSIONS: After PCV treatment, SRF and PED stabilized, as shown by OCT. However, the PED treatment response was both delayed and refractory compared to the SRF response. The small change in post-treatment PED diameter may suggest the possibility of PCV recurrence.
