Comparison of standard and innovative wide-field optical coherence tomography images in assessment of vitreoretinal interface in proliferative diabetic retinopathy: A pilot study

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 x 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.

Automated summary

This study compared the standard and innovative wide-field optical coherence tomography images in the assessment of vitreoretinal interface in proliferative diabetic retinopathy. The results showed that the innovative wide-field technique provided the widest OCT scans available with some minor quality issues compared to the standard technique.
