Flashes and corneal issues?

I have had keratoconus for about twelve years and have been regularly visiting the clinic every year.
This year, in early April, I noticed a small area in my vision that flashes when I blink.
After my follow-up appointment, I asked the doctor about it, and he said there was no issue, so I felt reassured.
However, after July, I discovered that in sunlight, that small area started to produce intense flashes and some color changes when I blink.
Could this be related to retinal detachment?

Hello: The sensation of flashes and changes in vision may be related to retinal issues and should be taken seriously.
Keratoconus itself can lead to blurred or distorted vision, but flashes and changes in color are less common.
Common symptoms of retinal detachment include a sudden increase in floaters, flashes of light, and visual field loss.
Although your symptoms may not be directly related to retinal detachment, it is advisable to see an ophthalmologist as soon as possible to assess the condition of your retina and rule out potential retinal detachment or other serious problems.
Ongoing changes in vision and flashes, especially in bright sunlight, warrant close attention.
Seeking medical attention promptly can help identify and address potential issues, ensuring the health of your vision.

More Info

Based on your description, it sounds like you are experiencing some concerning symptoms related to your eyes, particularly flashes of light and changes in vision. Given your history of keratoconus and regular check-ups, it is understandable that you would be vigilant about any changes in your eye health.

Flashes of light in the vision can indeed be associated with several ocular conditions, including retinal detachment. Retinal detachment occurs when the retina, the light-sensitive layer at the back of the eye, separates from its underlying supportive tissue. This can lead to serious vision loss if not treated promptly. Symptoms of retinal detachment often include sudden flashes of light, an increase in floaters, and a shadow or curtain effect over the visual field.
In your case, the fact that you have a history of keratoconus, which affects the cornea's shape and can lead to visual distortions, adds another layer of complexity. Keratoconus can cause irregular astigmatism, leading to visual disturbances, including flashes or halos around lights, particularly in bright conditions. However, the new onset of strong flashes, especially in sunlight, raises a concern that should not be overlooked.

The changes you describe, particularly the increase in flashes and the alteration in color perception, could be indicative of a few potential issues:
1. Retinal Issues: As mentioned, flashes of light can be a sign of retinal detachment or other retinal problems. Given your symptoms, it would be prudent to have a thorough examination of the retina, including a dilated fundus exam and possibly optical coherence tomography (OCT) to assess the retina's health.

2. Keratoconus Progression: Changes in your vision could also be related to the progression of keratoconus. As the cornea becomes more irregular, it can lead to increased visual disturbances, including flashes of light. This is particularly relevant if you are experiencing changes in your vision that correlate with your keratoconus.

3. Corneal Scarring or Changes: If there are any changes in the cornea due to keratoconus or other factors, this could also lead to visual disturbances. Scarring or irregularities on the corneal surface can cause light to scatter, leading to flashes or halos.

4. Other Ocular Conditions: Conditions such as posterior vitreous detachment (PVD) can also cause flashes of light. This occurs when the vitreous gel inside the eye pulls away from the retina, which can happen with age or due to other factors.

Given your symptoms and the potential seriousness of retinal detachment, I strongly recommend that you seek an immediate evaluation from an eye care professional. It is essential to communicate all your symptoms clearly, including the nature of the flashes, any changes in your vision, and your history of keratoconus.
In summary, while your symptoms could be related to keratoconus or other corneal issues, the presence of strong flashes of light, especially in bright conditions, warrants a thorough examination to rule out retinal detachment or other serious conditions. Early detection and treatment are crucial in preserving your vision. Please prioritize scheduling an appointment with your eye care provider as soon as possible.
