Abstract:
Objective:To observe the clinical efficacy of half-dose photodynamic therapy (PDT) in the treatment of acute central serous chorioretinopathy (CSC) by enhanced deep imaging-OCT (EDI-OCT).Methods:A retrospective case study. From September 2015 to November 2018, 100 patients with acute CSC who received half-dose PDT in Hangzhou Branch of the Eye Optometry Hospital of Wenzhou Medical University were included in the study. Among 100 patients, 69 patients were males and 31 patients were females; the average age was 49.63±7.97 years; the average duration of disease was 2.19±0.71 months. All patients underwent BCVA, EDI-OCT, FFA, ICGA and other examinations. BCVA was used on the international standard visual acuity chart and converted to logMAR visual acuity records. Before treatment, the average logMAR BCVA was 0.29±0.19, the average macular foveal retinal thickness (CMT) was 370.59±134.98 μm, and the average macular subfoveal choroidal thickness (SFCT) was 366.93±86.95 μm. All patients were treated with half-dose PDT. We compared the changes of BCVA, CMT, SFCT, and subretinal fluid (SRF) of the eye before treatment and 2 weeks after treatment and 1, 3, and 6 months. Pearson correlation analysis method was used to analyze the correlation between BCVA and baseline BCVA, CMT, SFCT after 6 months of treatment.Results:Six months after treatment, SRF was completely absorbed in 98 eyes, with an effective rate of 98.0%. Compared with before treatment, 2 weeks and 1, 3, and 6 months after treatment, the BCVA of the eye significantly increased ( F=66.493, P<0.001), and CMT and SFCT significantly decreased ( F=134.625, 30.394; P<0.001,<0.001). The results of Pearson correlation analysis showed that BCVA was positively correlated with baseline BCVA 6 months after treatment ( r=0.529, P<0.001), and there was no significant correlation with CMT and SFCT. There were no serious complications related to treatment during the follow-up period. Conclusions:Half-dose PDT can effectively increase BCVA in a short period of time for acute CSC. EDI-OCT can observe that CMT, SFCT and SRF absorption are significantly reduced after treatment.
