Abstract:
A 79-year-old male was hospitalized for respiratory failure secondary to coronavirus disease 2019 pneumonia. Approximately 6 hours after initiating proning, left globe subluxation with darkening of the superior sclera consistent with tache noir was noted. The left globe was thought to be hypotonus secondary to ciliary body shut down after a prolonged period of high intraocular pressure. The globe was reduced in the supine position with gentle traction of the eyelids. Over the next 24 hours, the left intraocular pressure improved to 10 mm Hg, and the tache-noir de la sclérotique resolved. The authors report the first known case of globe subluxation secondary to proning.
