Painful vision loss during air travel after vitrectomy with air tamponade: a case report.

Background: While the potentially hazardous effects of intraocular perfluorocarbon gases during air travel have been recognized, the equivalent risk of intraocular air tamponade is less known and has, to the best of our knowledge, not been reported yet.

Case Presentation: A 52-year-old white female experienced a complete loss of vision and pain in her left eye during air travel following pars plana vitrectomy with air tamponade. Clinical and multimodal imaging findings only a few hours after emergency landing indicated a transient central retinal artery occlusion due to a significant increase in intraocular pressure during the flight.

Customized 3D printed bioreactors for decellularization-High efficiency and quality on a budget.

Decellularization (DC) of biomaterials with bioreactors is widely used to produce scaffolds for tissue engineering. This study uses 3D printing to develop efficient but low-cost DC bioreactors. Two bioreactors were developed to decellularize pericardial patches and vascular grafts.
