【 摘 要 】

Purpose: To report findings on the tilt angle of optic nerve heads (ONHs) that developed intrapapillary hemorrhage with adjacent peripapillary subretinal hemorrhage (IHAPSH) using swept-source optical coherence tomography (SS-OCT). Observations: Five consecutive patients who presented with IHAPSH were reviewed retrospectively. We reviewed five consecutive eyes from the five patients, analyzed the optic tilt angle obtained from SS-OCT B-scans, and compared the results and other clinical characteristics. All patients had larger optic disc tilt angles in the eyes with IHAPSH than in the contralateral, unaffected eye. The mean ratio of the tilt angle in the eyes with IHAPSH to that in the contralateral eye was 1.37 (95% confidence interval 1.15–1.58). Conclusions and Importance: The ONH of IHAPSH was evaluated quantitatively with SS-OCT for the first time in this study. Larger angle tilted discs in IHAPSH-affected eyes are anatomically and histologically more vulnerable and may explain why IHAPSH develops monocularly.
