UNASSIGNED: From April 2020 to September 2022, we enrolled patients who were diagnosed with TON and underwent endoscopic optic nerve decompression at our institution. Vision and pupil reflex tests were performed by an ophthalmologist before and after surgery.
UNASSIGNED: Seven patients were enrolled. Their ages ranged from 9 to 78 years and all were male. Among the 7 patients, the patient whose pupillary light reflex was 6mm with sluggish and 7mm with fixated pupil before surgery showed no improvement in vision. Patients with some response to direct reflex or contralateral indirect reflex testing preoperative showed vision improvement postoperative.
UNASSIGNED: Direct and indirect pupillary reflexes can be important factors determining treatment for TON. In unconscious patients with a fracture involving the optic canal, timely surgical intervention based on pupillary reflex can prevent permanent loss of vision.
■从2020年4月至2022年9月,我们招募了诊断为TON并在我们机构接受内窥镜视神经减压术的患者。眼科医生在手术前后进行了视力和瞳孔反射测试。
■7名患者入组。他们的年龄从9岁到78岁不等,都是男性。在7名患者中,手术前瞳孔光反射为6mm,缓慢,瞳孔固定为7mm的患者视力无改善。术前对直接反射或对侧间接反射测试有一定反应的患者术后视力改善。
■直接和间接瞳孔反射可能是决定TON治疗的重要因素。在昏迷的视神经管骨折患者中,及时进行基于瞳孔反射的手术干预可以防止永久性视力丧失。
