Retinal detachment
Retinal detachment can cause sensations of flashes of light, similar to lightning.
However, I also experience visual snow syndrome, where I see persistent blue dots and flashes in dark areas, even with my eyes closed for 24 hours.
Doesn't this make it difficult to determine when a retinal detachment occurs? I see a shadow flashing in my vision, and even with my eyes closed, I can still see this shadow.
Will continuous deterioration of my eyesight lead to blindness?

First, go to the outpatient clinic to confirm whether there are any retinal lesions.
If there are any significant new symptoms in addition to the current ones, an immediate re-examination should be conducted.
If everything remains stable, at least one follow-up should be done annually.

More Info
Retinal detachment is a serious eye condition that occurs when the retina, a thin layer of tissue at the back of the eye, pulls away from its normal position. This can lead to permanent vision loss if not treated promptly. Understanding the symptoms and concerns associated with retinal detachment is crucial for early detection and intervention.
Symptoms of Retinal Detachment
1. Flashes of Light: Many patients report seeing sudden flashes of light, often described as "lightning streaks" or "flashes." This occurs due to the retina being stimulated by the pulling force of the vitreous gel, which can happen during the detachment process.
2. Floaters: The appearance of floaters, which are small spots or lines that drift through your field of vision, is common. These can be more pronounced in individuals with myopia (nearsightedness) or those who have had cataract surgery.
3. Dark Shadows or Curtains: A significant symptom of retinal detachment is the perception of a shadow or curtain descending over your vision. This can indicate that the retina is detaching from the underlying tissue.
4. Blurred Vision: Sudden changes in vision, such as blurriness or a decrease in visual acuity, can also be a sign of retinal detachment.
5. Persistent Black Spots: If you are experiencing persistent black spots or shadows in your vision, especially if they are accompanied by flashes or floaters, this could indicate a serious issue.
Your Symptoms
In your case, you mentioned experiencing flashes that resemble lightning and persistent blue spots in dark areas, even when your eyes are closed. These symptoms can be alarming and may suggest retinal issues, including potential detachment. The fact that you see these flashes continuously, even with your eyes closed, is concerning and warrants immediate medical attention.
Concerns About Vision Loss
Retinal detachment can lead to significant vision loss if not treated quickly. If the retina is not reattached promptly, the affected area can become permanently damaged, leading to irreversible vision loss. The presence of ongoing symptoms like flashes and shadows should not be ignored. It is essential to seek an eye care professional's evaluation as soon as possible.
What to Do Next
1. Immediate Consultation: Given your symptoms, it is crucial to consult an ophthalmologist or visit an emergency eye care facility. They can perform a thorough examination, including a dilated eye exam, to assess the condition of your retina.
2. Monitoring Symptoms: Keep track of any changes in your vision, including the frequency and intensity of the flashes and floaters. Documenting these changes can provide valuable information to your eye care provider.
3. Avoid Strain: While waiting for your appointment, try to avoid activities that may strain your eyes, such as prolonged screen time or reading in dim light.
4. Follow-Up Care: If diagnosed with retinal detachment or any related condition, follow your doctor's recommendations for treatment, which may include surgery or laser therapy to reattach the retina.
Conclusion
In summary, your symptoms of flashes and persistent visual disturbances are concerning and could indicate retinal detachment or other serious eye conditions. It is vital to seek immediate medical attention to prevent potential vision loss. Early diagnosis and treatment are key to preserving your eyesight. Remember, your vision is precious, and any significant changes should be taken seriously.
