Abstract
Purpose: To investigate the comparative efficacy and safety of half-dose photodynamic therapy (PDT) and half-fluence PDT in the management of chronic central serous chorioretinopathy (cCSCR).
Design: Systematic review and meta-analysis METHODS: A comprehensive literature search was conducted on Ovid MEDLINE, Embase, and the Cochrane Library, covering publications from January 2000 to March 2024. The review focused on studies reporting the efficacy and safety of half-dose PDT compared to half-fluence PDT in treating cCSCR. The primary outcome was the best-corrected visual acuity (BCVA) at the last study observation. Secondary outcomes included retinal thickness (RT), the presence of subretinal fluid (SRF), and SRF recurrence across follow-up visits. Random effects meta-analysis was performed using RevMan 5.4.
Results: A total of 10 studies (eight observational and two randomized controlled trials) were included in the analysis. The results indicated that half-dose PDT and half-fluence PDT achieved similar BCVA at 1 month (p=0.24), 3 months (p=0.40), and 6 months (p=0.16). Similarly, there were no significant differences in RT at 1 month (p=0.23), 3 months (p=0.99), and at 6 months (p=0.54) between the two treatment protocols. Both treatment protocols were associated with minor complications, indicating similar safety profiles in patients with CSCR.
Conclusion: The findings suggest that both half-dose and half-fluence PDT are effective and safe for treating CSCR, with no significant differences in BCVA, RT, or SRF resolution between the two modalities. These results support flexibility in selecting treatment based on individual patient needs. Further research with larger sample sizes and longer follow-up is required to optimize these protocols and confirm these results.
