- Abstract
Purpose: To investigate the efficacy and safety of quadrant laser photocoagulation to ameliorate the choroidal congestion in central serous choroidopathy (CSC). Study design: Historically controlled study. Methods: We prospectively studied 20 eyes with acute CSC in the quadrant laser group, in which laser photocoagulation was applied to the macular leakage point(s) as well as the quadrant of the fundus showing vortex vein dilatation. Central choroidal thickness (CCT), vertical diameter of dilated vortex vein, resolution rate of serous retinal detachment (SRD), and visual field were evaluated post-treatment. We also compared the results with those of 18 retrospectively analyzed eyes with acute CSC in an external control group, in which laser photocoagulation had been applied only to the macular leakage point(s). Results: In the quadrant laser group, 2 eyes were excluded from data analysis due to choroidal neovascularization (CNV). CCT was significantly reduced in both groups, but more significantly in the quadrant laser group. The vertical diameter of the dilated vortex vein was significantly decreased only in the quadrant laser group. The resolution rate of SRD was similar in the two groups. In the quadrant laser group, 8 eyes (44.4%) showed mild deterioration of the visual field, consistent with the area subjected to quadrant laser photocoagulation. Conclusion: Quadrant laser photocoagulation can have limited efficacy for ameliorating vortex vein congestion in CSC. When laser photocoagulation to the macular area is combined with quadrant laser photocoagulation, attention must be paid to the possible development of CNV and visual field deterioration.
