It was a bright summer afternoon, and I had just settled at the local community picnic when I noticed Steve, a carpenter I had met several times during town events, squinting and rubbing his eye. “Dr. Priya,” he called out, his voice tinged with urgency. “I think something got into my eye while I was working on the wooden benches this morning.”
As Steve explained his discomfort, it was clear that he might have a foreign body in his eye. I decided to walk him through what might be happening and what he needed to do next.
What Is a Foreign Body in the Eye?
A foreign body in the eye refers to any object that does not naturally belong in or on the eye. This could range from tiny particles like dust or sand to more significant fragments such as wood splinters, metal shavings, or even sawdust.
Foreign bodies can lodge on the cornea (the clear front surface of the eye), under the eyelid (conjunctival foreign body), or inside the eye itself (intraocular foreign body), the latter being the most serious. Understanding the location of the foreign object helps determine the urgency and type of care needed.
Types of Foreign Bodies in the Eye
| Type | Description |
|---|---|
| Corneal Foreign Body | Lodged on the clear surface of the eye; commonly causes irritation and redness. |
| Conjunctival Foreign Body | Stuck under the eyelid or on the skin around the eye. |
| Intraocular Foreign Body | Inside the eye, often serious and requiring immediate medical attention. |
Symptoms of a Foreign Body in the Eye
Steve mentioned sharp pain and excessive watering from his eye. These are classic symptoms. Common symptoms include:
- Eye Pain or Discomfort: Ranging from mild irritation to severe pain.
- Watery Eye: A natural response to flush out the foreign object.
- Blurred Vision: Caused by the object or irritation.
- Redness: Due to inflammation.
- Sensitivity to Light: Photophobia can occur when the cornea is irritated.
- Feeling of “Something in the Eye”: Persistent discomfort despite attempts to rinse the eye.
What Causes Foreign Bodies in the Eye?
In Steve’s case, it was wood particles from his carpentry work. But other common causes include:
- Environmental Factors: Windblown dust, sand, or debris.
- Occupational Hazards: Tradespeople like carpenters, welders, and metalworkers are at higher risk.
- DIY or Home Repairs: Activities like drilling or grinding without eye protection.
Risks and Dangers
While most foreign bodies are minor and easily treatable, certain scenarios can lead to serious complications:
- Intraocular Foreign Bodies: Can lead to infection or permanent vision loss if untreated.
- Metallic Fragments: May rust, leaving a scar on the cornea.
- Corneal Abrasions: Scratches on the cornea from the foreign body or during attempts to remove it.
First Aid for Foreign Bodies
I advised Steve to avoid rubbing his eye, as this could push the object deeper or scratch the cornea further. Instead, here’s a general first-aid approach:
- Flush the Eye: Use clean water or saline solution to rinse the eye gently.
- Do Not Remove the Object Yourself: Especially if it is embedded in the eye.
- Blink Repeatedly: This may help dislodge smaller particles.
- Seek Medical Attention: If discomfort persists or the object is not visible.
Medical Treatment
If first aid doesn’t resolve the issue, it’s crucial to see a healthcare professional. Here’s what treatment might involve:
- Local Examination: The doctor uses a slit-lamp microscope to locate and assess the foreign body.
- Anaesthetic Drops: Numbing the eye for a pain-free removal process.
- Removal Tools:
- Cotton buds or fine needles for superficial objects.
- Specialized instruments for deeper or embedded foreign bodies.
- Antibiotic Drops or Ointment: To prevent infection.
- Eye Patch: Used to protect the eye and promote healing in cases of corneal abrasion.
Follow-Up Care
After the foreign body is removed, follow-up care is essential:
- Use of Eye Drops: To soothe the eye and prevent infection.
- Avoid Strenuous Eye Activity: Rest the eye, especially if there’s a corneal abrasion.
- Attend Scheduled Check-Ups: To ensure proper healing.
Preventing Foreign Bodies in the Eye
As Steve nodded along, I emphasized the importance of prevention, particularly for someone in his line of work:
- Wear protective eyewear, especially during activities like grinding, drilling, or sawing.
- Avoid standing too close to sources of flying debris.
- Use eyewear with side shields for added protection in dusty or windy environments.
Steve’s Recovery
Two days later, Steve gave me a call. “Dr. Priya, my eye feels so much better now. I’ve also invested in high-quality safety glasses. Thank you for walking me through everything.”
Hearing this brought me relief. Educating patients not only solves the immediate problem but also empowers them to take proactive steps for future prevention.
