Deep Red Spots on the Retina: Causes and Follow-Up - Ophthalmology

Share to:

There is a small area on the retina that appears deep red?


Hello, Doctor.
I had a dilated eye exam in mid-June.
The results showed no issues with my left eye, but there was a deep red area in the lower part of my right eye.
The doctor who examined me mentioned that the blood vessels underneath that area appeared normal, and there were no tears or detachments, suggesting it might be due to poor circulation.
I was advised to return for a follow-up in two months.
The next day, I underwent a visual field test, which also came back normal.
The doctor there said it was nothing to worry about and recommended continued monitoring.

Today, during my follow-up appointment, my left eye remained fine, but the deep red area in my right eye has not improved; it hasn't changed in size, and the blood vessels are still flowing normally.
I was advised to continue observation and return for another dilated eye exam in two months.
I would like to ask what kind of issue this might be, as I haven't noticed any changes in my vision, whether during the day or at night.
Thank you, Doctor.

Hello Wei: If there are no issues, there is no need to worry too much; it should not have any impact.
However, I cannot guess what the problem is; perhaps it is related to the blood vessels! It would be advisable to have a physician evaluate whether a fluorescein angiography is necessary.
In Taiwan, the Department of Ophthalmology at Puzi Hospital 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 can only serve as a reference; if necessary, you should visit a medical institution for treatment.
I hope to have the opportunity to assist you.

More Info


The presence of a deep red spot on the retina, particularly when it remains stable over time and does not exhibit any signs of bleeding or retinal detachment, can be concerning for patients. However, based on the information provided, it appears that your eye care professionals have conducted thorough examinations and have not found any significant issues that would warrant immediate concern.

The deep red area you are observing could be attributed to several factors, including but not limited to:
1. Choroidal Nevus: This is a benign pigmented lesion in the choroid layer of the eye. It can appear as a red or brown spot and is usually harmless. Regular monitoring is essential to ensure it does not change in size or appearance.

2. Retinal Hemorrhage: While your doctors have indicated that there is no bleeding, it is worth noting that small, localized hemorrhages can sometimes appear as red spots. These can be caused by various factors, including trauma, hypertension, or diabetes. Since your blood vessels were reported as normal, this seems less likely.

3. Circulatory Issues: As mentioned by your doctor, poor circulation could lead to changes in the coloration of the retinal tissue. This could be due to various underlying conditions, including vascular occlusions or other systemic issues that affect blood flow.

4. Inflammation: Conditions such as uveitis or other inflammatory processes can cause changes in the appearance of the retina. However, these typically present with additional symptoms such as pain, redness, or changes in vision.

5. Retinal Pigment Epithelium Changes: Sometimes, changes in the retinal pigment epithelium can lead to alterations in coloration. These changes can be benign but may require monitoring to ensure they do not progress.

Given that your vision remains stable and you are not experiencing any additional symptoms, the recommendation to continue monitoring is appropriate. Regular follow-ups, as suggested by your healthcare providers, are crucial in ensuring that any changes can be detected early.
It is also important to maintain a healthy lifestyle, including managing any systemic conditions (like hypertension or diabetes) and avoiding smoking, which can contribute to retinal health. If you notice any changes in your vision, such as new floaters, flashes of light, or a sudden decrease in vision, it is essential to seek immediate medical attention.

In conclusion, while the deep red spot on your retina may be concerning, the lack of significant changes and the normal findings from your eye examinations suggest that it may not be a serious issue. Continuing to follow up with your eye care provider is the best course of action. If you have any further concerns or if your symptoms change, do not hesitate to reach out to your healthcare provider for additional evaluation.
