Air travel has been contraindicated for patients with intraocular gas on the basis of experimental studies, because of the risk of elevated intraocular pressure during atmospheric depressurization.
A clinical study of gas bubble volume and intraocular pressure rise during a low-altitude air flight was performed on a patient with a gas bubble volume of 65% after retinal detachment surgery.
The flight was well tolerated, and the patient did not experience pain or decreased vision. The maximum altitude of the flight was 3,000. Maximum intraocular pressure was 49 mmHg, with a baseline of 16 mmHg. Increases in intraocular pressure and bubble volume were instantaneous with changes in altitude. Implications for pressurized flight situations are discussed.
Low-altitude air flight can be well tolerated by patients with intraocular gas, even with a relatively large vitreous cavity gas fill. Decisions about when to let patients with intraocular gas fly should be made on an case-to-case basis, depending on ocular factors and the planned flight characteristics.
基于实验研究，眼内有气体的患者一直被禁止乘坐飞机，因为在大气减压过程中存在眼内压升高的风险。
对一名视网膜脱离手术后气泡体积为65%的患者进行了一项关于低空飞行过程中气泡体积和眼内压升高的临床研究。
飞行耐受性良好，患者未出现疼痛或视力下降。飞行的最大高度为3000米。最大眼内压为49 mmHg，基线为16 mmHg。眼内压和气泡体积随高度变化瞬间增加。讨论了对增压飞行情况的影响。
眼内有气体的患者即使玻璃体腔气体填充量相对较大，也能很好地耐受低空飞行。关于何时允许眼内有气体的患者飞行的决定应根据具体情况，依据眼部因素和计划飞行特点来做出。
