Purpose: The purpose was to establish the position of fovea centralis optic nerve via en-face, near-infrared spectral domain optical coherence tomography (NIR-OCT) in healthy patients. This may shed light on physiological variability and be used for studying subtle cases foveal ectopia macular pathology after retinal detachment. Methods: SD-OCT data 890 eyes were retrospectively analyzed. Exclusion criteria included axial myopia causing tilting disc, peripapillary atrophy >1/3 width images excluding greater than half patients unable maintain vertical head positioning. Two independent reviewers measured horizontal distance from disc center diameter cross-sectional en-face scanning laser ophthalmoloscopy OCT imaging. Results: study. right left differed (4359 vs. 4248 µm, P < 0.001) (464 µm 647, 0.001). corresponded a smaller angle between (6.07° 8.67°, Older age associated with larger (P = 0.008) (0.025). These differences persisted correcting length 487 axial-length data. Conclusions: study compares among individuals without micron level basis. significant indicates that contralateral eye evaluation cannot reliably used. Rather, true requires assessments preoperative postoperative NIR-OCT scans. finding is relevant detachment ectopia. Translational Relevance:
