Corneal edema
Hello, doctor.
I would like to ask, if I suddenly experience swelling of the sclera (the white part of the eye) at night or outdoors, and it even appears that the eyeball is slightly retracted, what should I do? Are there any methods to alleviate or reduce the swelling on the spot?
Mr. Hsu, 10~19 year old female. Ask Date: 2011/05/01
Dr. Hu Yusheng reply Ophthalmology
Hello Mr.
Hsu: The conjunctival edema is likely caused by an allergy.
You can initially use cold compresses to reduce the swelling, or consult an ophthalmologist for further treatment and preventive measures.
Thank you for your inquiry, and I wish you health and safety.
Sincerely, Dr.
Hu Yu-Sheng, Ophthalmologist.

More Info
Sudden swelling of the eyeball, particularly the white part (sclera), can be alarming and may indicate various underlying issues, ranging from allergic reactions to infections or even trauma. Here are some steps you can take for immediate relief and management, as well as some insights into potential causes and when to seek medical attention.
Immediate Relief Tips
1. Cold Compress: Applying a cold compress to the affected eye can help reduce swelling and provide immediate relief. You can use a clean cloth soaked in cold water or a cold pack wrapped in a towel. Apply it gently to the eye for about 10-15 minutes. This can help constrict blood vessels and reduce inflammation.
2. Avoid Rubbing: It’s crucial not to rub or touch the swollen area, as this can exacerbate the swelling and potentially introduce bacteria, leading to infection.
3. Elevate Your Head: If you are lying down, try to elevate your head with an extra pillow. This can help reduce swelling by allowing fluids to drain away from the eye.
4. Stay Hydrated: Drinking plenty of water can help your body manage inflammation and reduce swelling.
5. Over-the-Counter Antihistamines: If you suspect that the swelling is due to an allergic reaction (for example, from pollen, dust, or pet dander), taking an over-the-counter antihistamine may help alleviate symptoms.
Potential Causes of Eyeball Swelling
1. Allergic Reactions: Allergies can cause the eyes to swell, often accompanied by redness, itching, and tearing. Common allergens include pollen, dust mites, pet dander, and certain foods.
2. Infections: Conditions such as conjunctivitis (pink eye) or other eye infections can lead to swelling. These may be accompanied by discharge, redness, and discomfort.
3. Injury or Trauma: Any direct trauma to the eye can result in swelling. This could be from a physical impact or even from something like a foreign body entering the eye.
4. Fluid Retention: Sometimes, fluid retention due to systemic conditions (like kidney issues or hormonal changes) can cause swelling around the eyes.
5. Other Medical Conditions: Conditions such as thyroid disease (Graves' disease) can lead to swelling of the eyes.
When to Seek Medical Attention
While mild swelling may resolve with home care, you should seek medical attention if:
- The swelling persists or worsens despite home treatment.
- You experience significant pain, vision changes, or sensitivity to light.
- There is discharge from the eye, especially if it is yellow or green.
- You have a history of eye problems or recent eye surgery.
- You suspect an allergic reaction that is severe or accompanied by other symptoms like difficulty breathing or swelling in other areas.
Conclusion
In summary, sudden swelling of the eyeball can be managed initially with cold compresses, elevation, and possibly antihistamines if allergies are suspected. However, it is essential to monitor your symptoms closely and consult a healthcare professional if the condition does not improve or if you experience additional concerning symptoms. Remember, your eyes are delicate organs, and prompt attention to unusual changes is always the best course of action.
