Abstract Details


We report a case of a 77 years pseudophakic old patient known for bilateral fuch's endothelial cornea dystrophy (FECD) who experienced a bilateral corneal decompensation during consecutively a flight and a mountain trek. Physiopathological possibles mechanisms are presented.


The patient had bilateral endothelial decompensation with corneal oedema and Descemet folds, first after a 2 hours airplane flight and again after a mountain trek.


Pentacam’s topography and visual acuity a day before and after the flight and the mountain trek are evaluated and the atmospheric pressure was recorded.


Baseline best corrected visual acuity (BCVA) was 0.8 and decreased to 0.6 after each experience, associated to corneal oedema and descemet folds with a normal intraocular pressure and quiet anterior chamber. The patient was treated with topical Nacl 0.5% 5 times a day with a full recovery after two weeks.


Ophthalmologist and physicians following FECD patient should be aware of this possible risk of corneal decompensation in low-pressure environnement. FINANCIAL DISCLOSURE?: No
