What to do about conjunctivitis?


Hello, doctor.
Today I feel something unusual with my left eye.
When I looked in the mirror, I noticed an issue with my eyelid.
I pulled down my lower eyelid and saw that the outer part of my left lower eyelid is very red (the eyeball itself is not red).
In comparison, my right eyelid has only a slight redness (normal).
Clearly, the redness in my left eyelid is much more pronounced.
I searched online and found that it might be conjunctivitis, which mentions that it can be accompanied by itching and pain (I only have a little pain, no itching).
It also said that cold compresses or 7-10 days would help it heal on its own.

1.
Is this true?
2.
Is this acute or chronic?
3.
Will this affect my vision?
4.
What should I do? Thank you.

Hello Popcat: It could possibly be conjunctivitis, so it's best to see an ophthalmologist for an examination.
If it resolves, it shouldn't affect your vision, so please don't worry.
Online answers can only serve as a reference; if necessary, you should seek medical attention at a healthcare facility.

More Info


Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, the thin membrane that covers the white part of the eyeball and lines the inside of the eyelids. Your symptoms of redness in the lower eyelid, along with mild pain but no itching, suggest that you may be experiencing a form of conjunctivitis. Let's address your questions one by one.

1. Is it true that conjunctivitis can resolve on its own in 7-10 days?
Yes, many cases of conjunctivitis, particularly viral and allergic types, can resolve on their own within a week to ten days. However, bacterial conjunctivitis may require antibiotic treatment to speed up recovery and prevent complications. Cold compresses can help alleviate discomfort and reduce swelling, but it's essential to monitor your symptoms closely.

2. Is this acute or chronic?
Based on your description, it sounds like you are experiencing acute conjunctivitis. Acute conjunctivitis typically appears suddenly and lasts for a short duration, whereas chronic conjunctivitis persists for weeks or longer and may be associated with underlying conditions or repeated exposure to irritants or allergens. If your symptoms do not improve or worsen over the next few days, it would be wise to consult a healthcare professional for further evaluation.

3. Will this affect my vision?
While conjunctivitis itself usually does not cause permanent vision loss, it can lead to temporary vision changes, such as blurriness or discomfort, especially if there is significant tearing or discharge. If the inflammation is severe or if there are complications, such as keratitis (inflammation of the cornea), it could potentially impact your vision. If you notice any sudden changes in your vision, such as increased blurriness or loss of vision, you should seek medical attention immediately.

4. What should I do next?
Here are some steps you can take:
- Cold Compress: Apply a clean, cold compress to your eye for 5-10 minutes several times a day to reduce swelling and discomfort.

- Avoid Irritants: Stay away from smoke, dust, and other irritants that could exacerbate your symptoms.

- Hygiene: Wash your hands frequently and avoid touching your eyes. If you wear contact lenses, consider switching to glasses until your symptoms resolve.

- Monitor Symptoms: Keep an eye on your symptoms. If they worsen or do not improve within a few days, or if you develop additional symptoms such as increased pain, significant discharge, or vision changes, it’s important to see an eye care professional for a thorough examination and appropriate treatment.

In summary, while your symptoms may indicate a mild case of conjunctivitis that could resolve on its own, it’s crucial to monitor your condition closely. If you have any concerns or if your symptoms change, do not hesitate to seek medical advice. Early intervention can help prevent complications and ensure a quicker recovery.
