Abstract

Purpose: Retrobulbar hematoma (RBH) is a rare but serious vision threatening emergency. We analyze the relationship between hematoma volume, visual impairment and outcome. Methods: Fifty-four patients with RBH receiving orbital decompression were retrospectively included. Volumetric analysis of RBH was performed by semi-automatic segmentation based on pre-operative CT scans using ITK-SNAP software. Best corrected visual acuity (BCVA) measurements were obtained and correlated in 2 groups (no light perception (NLP), severe visual impairment) with the hematoma volume. Results: NLP was documented preoperatively in 5/28 and postoperatively in 9/43 patients. Preoperative NLP was significantly associated with a larger hematoma volume (P = .03) and higher hematoma/ orbital volume ratio (P = .03). Postoperative severe visual impairment showed significant associations with a larger hematoma volume (P = .02) as well as higher hematoma/orbital volume ratio (P = .02). Conclusion: Eyes with severe visual impairment and large hematoma volumes preoperatively are at high risk of permanent vision loss. Hematoma volume calculation might represent an additional prognos- tic parameter for visual outcome after RBH. (C) 2021 The American Association of Oral and Maxillofacial Surgeons.
