Purpose: The purpose of this study was to report a case of nasal dragging and sliding of retina over the optic disk, as documented by spectral-domain optical coherence tomography.
Methods: Case report.
Results: We present the case of a 22-year-old woman with a history of retinopathy of prematurity noted to have nasal dragging of the retina, stable at least since the patient was 21 months old. Spectral domain optical coherence tomography showed folding of the temporal retina over the disk and the adjacent nasal retina, contributing to the nasal diversion of the vessels within the fold.
Conclusion: Despite retinal anchoring at the optic nerve, the disk does not appear to serve as a barrier to retinal movement. Spectral domain optical coherence tomography showed in vivo a mechanism through which nasal dragging can occur, namely through the sliding and folding of temporal retina over the disk and the adjacent nasal retina.
