Abstract | Aim: To evaluate the effect of scleral buckling on intraocular pressure (IOP) change during atmospheric decompression for eyes with small volumes of intravitreal gas. Methods: 12 eyes of 12 patients, including 6 with and 6 without scleral buckles, were evaluated in a hypobaric chamber simulating air travel approximately 1 month post pars plana vitrectomy with 15% C 3F8 gas fluid exchange. The chamber was decompressed with an ascent rate of 300 feet/min to a peak altitude of 8000 feet. After 15 min of cruising, descent was undertaken at 300 feet/min. IOP was measured at baseline and then every 5 min using slit-lamp mounted Goldmann applanation tonometry. The data were entered onto a spreadsheet and comparative statistics were done. Results: During ascent, IOP steadily rose from an average of 13±3 mm Hg to a peak of 26±9 mm Hg at 8000 feet. Patients with scleral buckles had significantly lower peak IOPs compared with those without buckles (20±5 mm Hg vs 32±8 mm Hg, p=0.013, t test) representing lower absolute increases in IOP (7±1 mm Hg vs 19±7 mm Hg, p=0.001, t test) and lower percentage increases in IOP from baseline (62±25% vs 140±40%, respectively). Conclusions: Eyes with small volumes of intravitreal gas demonstrate significant IOP changes during atmospheric decompression in simulated flight. The presence of a scleral buckle significantly limits the magnitude of IOP change, suggesting that such patients can likely tolerate typical air travel without undue risk of dangerous IOP elevation. |
