Which practice helps prevent corneal drying in Bell palsy?

• A. Ointment at bedtime
• B. Start systemic antibiotics
• C. Wear contact lenses
• D. Laser therapy

Answer: (A)

When facial nerve palsy causes the eyelid to not close completely, the cornea is exposed and dries out, especially during sleep. Putting an ophthalmic ointment at bedtime creates a protective, lubricating layer that seals moisture and reduces evaporation while the eye is closed. This simple step directly guards the cornea against exposure keratopathy during the night and helps preserve surface health as blinking and lid closure improve. Systemic antibiotics don’t address dryness, wearing contact lenses can worsen moisture loss and isn’t a preventive measure, and laser therapy isn’t used for this ocular surface issue.
