Objectives: We aimed to investigate the short-term changes in macular choroidal thickness and volume after Panretinal Photocoagulation (PRP) in patients with Proliferative Diabetic Retinopathy (PDR) using a choroidal thickness map with Spectral-Domain Optical Coherence Tomography (SD-OCT).
Methods: In this retrospective study, we reviewed the charts of patients who received PRP for diabetic retinopathy. Central volume scans using a 25-scan pattern and macular thickness map protocols were subsequently performed using the Spectralis OCT before and 1 month after PRP. Retinal thickness was measured by automated segmentation and choroidal thickness was obtained using a volume scan program with manual segmentation. For segmentation of the choroidal layer, the reference lines of the retinal boundary were adjusted to the choroidal boundary. Macular .. View More»
