Purpose: We compared the efficacy of focal laser photocoagulation and intravitreal bevacizumab injection in the treatment of chronic central serous chorioretinopathy.
Methods: We conducted a retrospective analysis involving 46 eyes of 46 patients with chronic central serous chorioretinopathy who received focal laser photocoagulation (22 eyes) or intravitreal bevacizumab injection (24 eyes). Changes in best-corrected visual acuity (BVCA), central macular thickness, and rates of complete subretinal fluid (SRF) resolution and recurrence were compared over a 6-month period.
Results: Although the focal laser photocoagulation and intravitreal bevacizumab injection groups demonstrated a significant reduction in central macular thickness at 6 months (p < 0.001), no statistically significant differences were observed between these groups at the end of the follow-up period. Notably, a gradual improvement in BVCA was observed in both groups following initial treatment, with significant improvement seen at 6 months (p = 0.049 and p = 0.048 for the laser and injection groups, respectively).
However, no statistically significant difference in BVCA improvement was observed between the groups. Complete SRF resolution was achieved in 22 eyes in the laser group and 23 eyes in the injection group. Although recurrence of SRF was observed in 9 and 13 eyes in the laser and injection groups, respectively, there was no statistically significant difference between the groups (p = 0.229).
Conclusions: Focal laser photocoagulation and intravitreal bevacizumab injection significantly improved anatomical and visual acuity outcomes in patients with chronic central serous chorioretinopathy. Although focal laser photocoagulation was associated with more rapid visual recovery and a lower recurrence rate compared to intravitreal bevacizumab injection, further studies are needed to evaluate its potential complications.
