Endoscope-assisted vitrectomy for severe ocular trauma with corneal blood staining and no light perception: A clinical efficacy analysis

Objective To evaluate the clinical characteristics and therapeutic efficacy of endoscope-assisted vitrectomy (EAV) for severe ocular trauma complicated by corneal blood staining and no light perception (NLP). Methods A retrospective study was conducted on 23 eyes of 23 patients with severe ocular trauma, corneal blood staining, and NLP who underwent EAV. Among them, 21 eyes were complicated by retinal detachment (RD), and 2 eyes had corneal laceration. The mean interval from injury to surgery was 20.43 days (range, 5 to 64 days). Preoperatively, all eyes had NLP with a mean intraocular pressure (IOP) of 9.9 mmHg (range, 2 to 37.4 mmHg). The mean follow-up period was 8.62 months (range, 0.1 to 45 months). Results Postoperative visual acuity was significantly improved compared with preoperative levels (P < 0.05). Visual acuity recovered to light perception or better in 13 eyes (56.5%), with the best corrected visual acuity reaching 0.7 in one eye. Anatomical retinal reattachment was achieved in 10 of the 21 eyes (47.6%) with preoperative RD. The mean postoperative IOP was 12.50 mmHg (range, 5 to 24 mmHg), which was significantly higher than the preoperative mean (P < 0.05). Conclusion Endoscope-assisted vitrectomy is a safe and effective technique for managing severe ocular trauma with corneal blood staining and NLP. It facilitates visual function recovery and may help reduce the risk of phthisis bulbi.
