A case of retinal central vein occlusion (CRVO) in a 43-year-old man is presented in which hyperbaric oxygen (HBO2) was used as the only treatment method. CRVO is a relatively common cause of visual loss, with hypertension, diabetes, glaucoma and hypercoagulable conditions identified as risk factors. The patient in this report had none of these risk factors and declined treatments other than hyperbaric oxygen. HBO2 was effective in sustaining the ischemic retina and controlling retinal edema until the retina revascularized and vision stabilized. The initial visual acuity in the left eye was 20/200 (corrected), and after two hyperbaric treatments it was 20/30 (corrected). Following three months of HBO2 treatments the vision stabilized to 20/20 (corrected) in the affected eye. Treatment considerations in using HBO2 as adjunctive therapy for CRVO are early institution of treatment, and continuation of HBO2 until the retinal edema has resolved and vision has stabilized.
本文介绍了一例43岁男性视网膜中央静脉阻塞（CRVO）病例，该病例仅采用高压氧（HBO2）进行治疗。CRVO是导致视力丧失的一个相对常见原因，高血压、糖尿病、青光眼和高凝状态被确定为危险因素。本报告中的患者没有这些危险因素，并且拒绝了除高压氧之外的其他治疗。HBO2在维持缺血性视网膜和控制视网膜水肿方面有效，直至视网膜血管再通且视力稳定。左眼初始视力为20/200（矫正后），经过两次高压氧治疗后为20/30（矫正后）。经过三个月的HBO2治疗，患眼视力稳定在20/20（矫正后）。将HBO2用作CRVO辅助治疗的治疗考虑因素包括尽早开始治疗，以及持续使用HBO2直至视网膜水肿消退且视力稳定。
