Hee Seong Yoon_SCIENTIFIC POSTER 2015

Purpose:

To evaluate changes in subfoveal choroidal thickness (SFCT) after Pattern Scan Laser (PASCAL) panretinal photocoagulation (PRP) in patients with diabetic retinopathy.

Methods:

This study included 39 patients (50 eyes) treated with PRP using PASCAL then followed for at least 3 months. Patients were classified into 2 groups according to severity: very severe non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR). SFCT was measured by enhanced depth imaging (EDI) optical coherence tomography (OCT) (Cirrus-HD OCT, Carl Zeiss). The changes of SFCT was analyzed at 1 and 3 months after PRP.

Results:

SFCT was 270.42 ± 61.44 ㎠› before PRP, 264.52 ± 60.78 um at 1 month and 255.74 ± 56.89 um at 3 months after PRP. Significant change of SFCT was found at 3 months after PRP (p=0.036). Central macular thickness (CMT) was 275.56 ± 50.61 um before PRP and increased to 295.18 ± 52.80 um and 293.10 ± 57.24 um at 1, 3 months post-treatment (p=0.001, 0.007). There were no significant differences between groups in baseline and amount of change in SFCT after PRP.

Conclusion:

After PASCAL laser PRP, SFCT showed no significant change at 1 month, but significantly decreased at 3 months.
