NOT associated with obstructive sleep apnea?

• A. NTG
• B. NAION
• C. Floppy eyelid syndrome
• D. PSC cataracts

Answer: (D)

Obstructive sleep apnea mainly affects the eye through vascular regulation and eyelid mechanics. OSA can lead to nocturnal hypoxia and unstable optic nerve perfusion, which helps explain its associations with conditions like non-arteritic anterior ischemic optic neuropathy and normal tension glaucoma, where reduced blood flow or vascular dysregulation harms the optic nerve. It also often accompanies floppy eyelid syndrome, a condition linked to eyelid laxity and mechanical rubbing that can affect the ocular surface. Posterior subcapsular cataracts, however, form from lens-specific factors such as steroid exposure, diabetes, or inflammatory processes, not from nocturnal hypoxia or perfusion issues related to sleep apnea. Therefore, PSC cataracts are not considered associated with obstructive sleep apnea.
