Common Eye Concerns: When to See an Eye Doctor? - Ophthalmology

Inquiry about eye problems?


Hello, Doctor.
This morning while washing my face, I noticed some discharge in the corner of my eye.
When I rubbed it and looked in the mirror, it seemed to have moved onto the surface of my eyeball, but after rinsing with water, it disappeared.
I'm not sure if it was washed away.
Currently, I don't have any pain or foreign body sensation, but I'm worried if it could have gotten stuck in my eye.
I checked my eyelids and didn't see anything.
Do you think I need to see an ophthalmologist, or is it likely that it was washed away and I shouldn't be too concerned?
Additionally, I wanted to ask about the white part of my eye, which sometimes appears to have red streaks.
Is this normal? I recently visited a doctor who mentioned that a dark spot on the white part of my eye is normal and not to worry about it, but I forgot to ask about the appearance of the microvessels.
Thank you for your response.

Hello Z: Eye discharge is a natural secretion from the eyes, and if there is no sensation of foreign bodies when it enters the eye, it is not a concern.
It will resolve on its own.
The surface of the sclera (the white part of the eye) naturally contains many microvessels (conjunctiva), and having some blood vessels visible is normal.
If there is no discomfort, it is not a problem.
The ophthalmology department at Puzi Hospital in Taiwan is open on Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and Wednesday afternoons from 2:00 PM to 4:30 PM.
Online responses should only be used as a reference; if necessary, it is advisable to seek medical attention at a healthcare facility.
We hope to have the opportunity to serve you.

When it comes to common eye concerns, knowing when to see an eye doctor is crucial for maintaining good eye health. Based on your description, it seems you have experienced a few minor issues, such as the presence of discharge in the corner of your eye and some visible blood vessels in the white part of your eye (sclera). Let’s break down these concerns and discuss when it is appropriate to seek medical attention.

Firstly, regarding the discharge you noticed while washing your face, it is common for eyes to produce mucus, especially upon waking. This discharge can sometimes accumulate in the corners of the eyes and may appear to be on the eyeball itself. If you were able to wash it away without any pain, irritation, or persistent foreign body sensation, it is likely that you do not need to worry. However, if you experience any of the following symptoms, it would be wise to consult an eye doctor:
1. Persistent Discomfort: If you continue to feel discomfort, irritation, or a sensation of something being in your eye, it could indicate that a foreign body is indeed present or that there is an underlying issue such as an infection.

2. Changes in Vision: Any sudden changes in your vision, such as blurriness, double vision, or loss of vision, warrant immediate attention.

3. Increased Discharge: If the discharge becomes more frequent, changes color (especially to yellow or green), or is accompanied by redness and swelling, these could be signs of an eye infection, such as conjunctivitis.

Now, regarding the visible blood vessels in the sclera, it is not uncommon to see small blood vessels, especially if you have been rubbing your eyes or if your eyes are dry or irritated. These blood vessels can become more prominent due to various factors, including:
- Allergies: Allergies can cause eye irritation and lead to increased blood flow to the area, making the vessels more visible.

- Fatigue: Lack of sleep or prolonged screen time can cause eye strain, leading to redness and visible blood vessels.

- Environmental Factors: Exposure to smoke, dust, or other irritants can also cause your eyes to become red and bloodshot.

If your eye doctor previously assessed the black spots in your eye and deemed them normal, it is likely that the blood vessels you are seeing are also not a cause for concern. However, if you notice any significant changes, such as an increase in the number of visible blood vessels, or if you experience discomfort or vision changes, it is advisable to seek further evaluation.

In summary, while your current symptoms do not seem to indicate an urgent need for an eye examination, it is always better to err on the side of caution. If you have any doubts or if your symptoms change, do not hesitate to consult an eye care professional. Regular eye check-ups are essential, especially if you have any pre-existing conditions or if you experience frequent eye issues. Remember, your eyes are a vital part of your overall health, and taking proactive steps can help prevent more serious problems down the line.
