Abstract:
AIM:To evaluate the efficacy of half-dose verteporfin photodynamic therapy for central serous chorioretinophathy (CSC) in patients aged above 45 years old.METHODS:Thirty-two eyes of 30 patients aged above 45 years old with central serous chorioretinophathy were included,and all the eyes received half-dose verteporfin photodynamic therapy (PDT).Best-corrected visual acuity (BCVA),central macular thickness (CMT) and subretinal fluids absorption (SRF) were measured before and after treatment (1,3 and 6mo).RESULTS:The rate of SRF absorbing completely was 44％ at 1mo,63％ at 3mo and 75％ at 6mo.The difference in cure rate of the three time points was statistically significant (x2 =6.621,P=0.037).All the patients were divided into two groups according to the duration,patients in Group A were treated less than 6mo,Group B were ≥6mo.The mean LogMAR BCVA in the two groups were respectively 0.6149±0.4117 and 0.8167±0.4370 before treatment and the mean CMT were 409.47±129.422μ m and 395.82 ± 153.756μm before treatment.The difference between the two groups in the LogMAR BCVA was not statistically significant (F=0.303,P=0.823),but the time difference within the subjects was statistically significant (F=32.837,P＜ 0.001).In Group A,the differences of the LogMAR BCVA at pre-treatment,1 mo and 3mo was all statistically significant (P＜ 0.05),but the differences of the LogMAR BCVA at 3mo and 6mo was not statistically significant (t =2.024,P =0.063).In Group B,the differences of the LogMAR BCVA at any two time points were all statistically significant (P＜ 0.05).The difference between the two groups in the CMT was not statistically significant (F=0.064,P=0.978),but the time difference within the subjects was statistically significant (F=26.447,P＜0.001).In Group A,the differences of the CMT at any two time points were all statistically significant (P＜0.05).So were in Group B (P＜0.05).CONCLUSION:Half-dose verteporfin PDT was effective in treating CSC aged above 45 years old,it still could improve BCVA and subretinal fluids absorption.
