Abstract |
PURPOSE To evaluate changes in subfoveal choroidal thickness (SFCT) after patterned panretinal photocoagulation (PRP) using pattern scan laser (PASCAL) in patients with diabetic retinopathy. METHODS: This study included 39 patients (50 eyes) treated with patterned PRP using PASCAL and who were followed for at least 3 months. Patients were classified into 2 groups according to severity: severe non-proliferative diabetic retinopathy and proliferative diabetic retinopathy. SFCT was measured by enhanced depth imaging of spectral-domain optical coherence tomography. The change in SFCT was analyzed at 1 and 3 months after PRP. RESULTS: SFCT was 270.42 ± 61.44 µm before PRP, 264.52 ± 60.78 µm at 1 month, and 255.74 ± 56.89 µm at 3 months after PRP. Significant change of SFCT was found at 3 months after PRP. Central macular thickness was 275.56 ± 50.61 µm before PRP and increased to 295.18 ± 52.80 µm and 293.10 ± 57.24 µm at 1 and 3 months post-treatment, respectively. There were no significant differences between groups in SFCT at baseline or in the amount of change in SFCT after PRP. CONCLUSIONS: SFCT significantly decreased after patterned PRP using PASCAL. |
