Retinal Issues: Black Spots and Flashing Lights in Vision - Ophthalmology

More Info

---

The symptoms you are describing, including the appearance of a small black dot in your vision and flashes of light, can be concerning and warrant further investigation. Given that you recently had a retinal examination that showed no significant issues, it is important to consider a few potential explanations for your current symptoms.

Firstly, the small black dot you see when you close and then open your eye may be related to a phenomenon known as "visual persistence" or "afterimage." This occurs when the photoreceptors in your retina continue to send signals to your brain even after the stimulus (in this case, the light from a lamp or other bright source) has been removed. This can create the illusion of a lingering spot in your vision. However, if this dot is persistent and does not fade quickly, it may be indicative of other underlying issues.

The flashes of light you experience, particularly when you move your eyes quickly or after waking up, could be related to vitreous detachment. In individuals with high myopia (nearsightedness), the vitreous gel that fills the eye can become more liquefied and may pull away from the retina, leading to sensations of flashes or light. This is often benign, but it can sometimes lead to more serious conditions such as retinal tears or detachments, especially if accompanied by new floaters or changes in vision.

Given your history of myopia and the presence of floaters (which you mentioned in previous queries), it is crucial to monitor these symptoms closely. While your recent retinal examination did not reveal any significant problems, the emergence of new symptoms like the persistent black dot and flashes of light suggests that a follow-up examination may be necessary. It would be advisable to consult with an ophthalmologist who can perform a thorough examination of both the retina and the macula (the central part of the retina responsible for sharp vision) to rule out any potential issues.

In summary, while some of the symptoms you are experiencing could be benign, they can also indicate more serious conditions that require attention. It is essential to communicate these new symptoms to your eye care provider, who may recommend additional imaging or tests to ensure that your retina and overall eye health are intact. Early detection and intervention are key in preventing potential complications, especially in individuals with a history of retinal issues or high myopia.
