ObjectiveTo observe the effects of personalized clinical therapy for polypoidal choroidal vasculopathy (PCV). MethodsEighty-six eyes of 79 patients with PCV were enrolled in this study. There were 60 males (65 eyes) and 19 females (21 eyes). The average age was (64.48±13.15) years old. Best corrected visual acuity (BCVA), slit lamp ophthalmoscopy, fundus photography, optical coherence tomography (OCT), fundus fluorescein angiography (FFA) and/or indocyanine green angiography (ICGA) were measured. The average BCVA was 0.19±0..20. There were three groups in this study including photodynamic therapy (PDT) group (group A, 45 eyes), PDT and intravitreal ranibizumab injection group (group B, 31 eyes), and PDT combined with sub-Tenon's capsule triamcinolone acetonide injection group (group C, 10 eyes). Follow up begun at 1 month after the treatment. 40 eyes in group A were followed up for 1 to 12 months with the average 3.27 months.28 eyes in group B were followed up for 1 to 36 months with the average 6.68 months. 9 eyes in group C were followed up for 1 to 12 months with the average 5.67 months. Patients with recurrent or worsen lesions were followed by FFA or ICGA. Pre- and post-treatment BCVA and retinal thickness of the fovea were comparatively analyzed. ResultsAll eyes (100.0%) in group A, 20 eyes (64.52%) in group B and 9 eyes (90.00%) in group C received treatment only once. The mean BCVA at 1 month after treatment was significantly increased than the pre-treatment BCVA in all 3 groups (t=2.061, 3.262, 3.258; P<0.05), but no significant difference was found between the 3 groups (t=1.345, 0.683, 0.168; P>0.05). Compared to pre-treatment measures, the mean retinal thickness of the fovea was significantly decreased in group A and group B (t=2.239, 4.334; P<0.05), but not changed in group C (t=2.286, P>0.05) at 1 month after treatment. Thirteen eyes in group A were followed by FFA and (or) ICGA, which showed that there were 3 eyes with complete closed PCV and alleviated pigment epithelial detachment (PED), 4 eyes with partial closed PCV, 3 eyes with stable PCV and 3 eyes with worsen PCV. Ten eyes in group B were followed by FFA and (or) ICGA, which showed that there were 3 eyes with complete closed PCV, 3 eyes with partial closed PCV, 4 eyes with recurrence PCV. Five eyes in group C were followed by FFA and (or) ICGA, which showed that there were 4 eyes with complete closed PCV, 1 eyes with recurrence PCV. ConclusionAll 3 therapy strategies can stop or reduce PCV leakage and improve the visual acuity in some degree.
