To report a case of cilioretinal artery occlusion (CRAO) with central retinal vein occlusion (CRVO) after a journey to high altitude region and the use of late period hyperbaric oxygen (HBO) therapy successfully.
A previously healthy 48-year-old lowlander woman was admitted to our department for sudden blurred vision in her right eye started at 2 weeks prior to examination. The patient had a history of 1-month exposure to high altitude that finished a day before the onset of her complaints. The best corrected visual acuity (BCVA) was 10/20 in the right eye (RE) and 10/10 in the left eye. Fundus examination of the RE revealed whitening of the retina along the distribution of cilioretinal artery, sparing fovea, flame-shaped hemorrhages, and roth spots with minimally dilated and tortuous retinal veins. Visual field analysis revealed centrocecal scotoma. The patient was treated by a daily session of 2 h of HBO at 2.5 atmosphere absolute for 11 days. BCVA rised to a level of 20/20 for the RE and the scotomas were disappeared immediately after using of the HBO treatment.
CRVO related CRAO should be regarded as a rare complication of exposure to high altitude and HBO seems to be the treatment of choice of high altitude related co-occurence of CRVO and CRAO in the late period.
报告一例因高原旅行和后期高压氧（HBO）治疗而导致的睫状视网膜动脉阻塞（CRAO）合并视网膜中央静脉阻塞（CRVO）病例。
一名既往健康的 48 岁低海拔女性因右眼突然视力模糊而于检查前 2 周入院。患者有 1 个月的高原暴露史，在发病前一天结束。最佳矫正视力（BCVA）右眼为 10/20，左眼为 10/10。右眼眼底检查显示沿睫状视网膜动脉分布的视网膜变白，黄斑区保留，火焰状出血和 Roth 斑，视网膜静脉轻度扩张和扭曲。视野分析显示中心暗点。患者接受了每天 2 小时、2.5 个大气压绝对压力的 11 次 HBO 治疗。右眼 BCVA 提高至 20/20，立即使用 HBO 治疗后暗点消失。
CRVO 相关的 CRAO 应被视为高原暴露的罕见并发症，HBO 似乎是高原相关 CRVO 和 CRAO 后期同时发生的治疗选择。
