Abstract
Purpose:To compare the standard and “innovative wide-field” optical coherence tomography images in assessment of vitreoretinal interface in proliferative diabetic retinopathy.Methods:Fifty consecutive eyes of 25 patients with proliferative diabetic retinopathy underwent 12 × 12 mm radial swept source-optical coherence tomography (OCT) imaging using standard technique and innovative wide-field (+90D) technique. The image expansion ratio was calculated using Image J software.Results:Out of the 50 eyes, only in four eyes with +90 D were minimally misaligned or were having quality less than grade 2 as compared to standard OCT. The mean age group was 51 ± 4.5 years. The expansion ratio (scan length) increased by a factor of 1.65 ± 0.67 when obtained using +90 D technique.Conclusion:Innovative wide-field technique provides us with the widest of available OCT scans with the presently available machine and the software.
