    Spatial and Spectral Imaging of Retinal Laser Photocoagulation Burns

    Purpose: To correlate in vivo spatial and spectral morphologic changes of short to long-pulse 532-nm Nd:YAG retinal laser lesions using Fourier-domain optical coherence tomography (FD OCT), autofluorescence (AF), fluorescein angiography (FA) and multispectral imaging. Methods: Ten eyes with treatment-naive pre-proliferative or proliferative diabetic retinopathy were studied. A titration grid of laser burns at 20-, 100- and 200-milliseconds was applied to the nasal retina, and laser fluence titrated to produce four grades of laser lesion visibility: sub-visible (SV), barely-visible (BV, light-gray), threshold (TH, gray-white), and supra-threshold (ST, white). The AF, FA, FD-OCT, and multispectral imaging were performed 1-week before laser ...
