A 76-year-old man developed left-eye choroidal detachment about 7 weeks after his CPAP pressure was increased and a new, less-leaky mask was introduced.
2
The detachment progressed to a kissing configuration, with visual acuity declining to hand movements and intraocular pressure rising to 27 mm Hg.
3
The patient received topical dexamethasone and cyclopentolate, followed by dorzolamide plus timolol; CPAP therapy continued during ocular recovery.
4
The choroidal detachment had completely resolved anatomically by week 16, while visual acuity and intraocular pressure improved.
5
The authors proposed that greater effective positive airway pressure might impair choroidal venous drainage, but this single case could not establish causation.
