1. Epidemiology
- Rare occurrence in dentistry but possible during procedures using dental lasers (e.g., soft tissue surgery, whitening).
- Risk higher if protective eyewear is not used.
- Can affect dental professionals, assistants, or patients.
2. Expected Prognosis
- Mild injuries (photokeratitis, transient glare) often recover fully within days to weeks.
- Severe retinal burns or optic nerve damage may cause permanent vision loss.
- Early diagnosis and ophthalmologic care improve outcomes.
3. Natural Progression
- Initial symptoms: pain, tearing, blurred vision, photophobia.
- Without intervention, may progress to scarring, retinal damage, or permanent visual impairment.
- Healing depends on depth and site of injury.
4. Pathophysiology
- Laser light energy absorbed by ocular tissues → thermal, photochemical, or mechanical injury.
- Cornea & lens focus certain wavelengths on retina, increasing damage risk.
- Infrared & visible wavelengths can penetrate deeply, damaging retina; UV can harm cornea
5. Possible Complications
- Corneal burns or ulcers.
- Retinal burns, scotomas, or macular degeneration.
- Permanent partial or complete blindness in affected eye.
- Chronic eye pain or photophobia.
Frequently Asked Questions
Can dental procedures cause eye damage?
Rarely, but dental tools, laser procedures, and even anesthesia can sometimes affect vision temporarily or, in very rare cases, cause complications.
Why do I experience blurry vision after a dental procedure?
This can be due to the effects of local anesthesia, stress, or pressure on facial nerves. If it persists, consult a doctor.
Can dental infections spread to the eyes?
Yes, untreated dental infections can spread to the sinuses and even the eyes, leading to serious complications like orbital cellulitis.
How can I protect my eyes during a dental procedure?
Wearing protective eyewear, which most dentists provide, helps prevent accidental injury from debris or bright lights.
Should I be concerned if my vision changes after a dental visit?
If you experience sudden vision changes, pain, or prolonged blurriness, seek medical attention immediately.
