We present six cases of central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) that we recently treated with hyperbaric oxygen (HBO). Patients in three of the six cases, including the CRVO case, experienced near to complete restoration of their vision. Another case had marked improvement. Our findings are similar to other case studies with approximately 65-70% improvement in patients treated for CRAO. Physicians should be aware that rapid referral of CRAO and CRVO patients to HBO is efficacious. Such patients should be placed on 100% oxygen by non-rebreather mask as soon as the diagnosis is suspected, pending transportation to HBO.
我们介绍了最近用高压氧（HBO）治疗的6例视网膜中央动脉阻塞（CRAO）和视网膜中央静脉阻塞（CRVO）病例。6例中的3例患者，包括CRVO病例，视力接近完全恢复。另一例有显著改善。我们的发现与其他病例研究相似，CRAO治疗患者的改善率约为65-70%。医生应意识到，将CRAO和CRVO患者迅速转诊至HBO治疗是有效的。一旦怀疑诊断，此类患者在转运至HBO之前，应立即通过非重复呼吸面罩给予100%氧气。
