White Light Flashes in Vision: Causes and Solutions

Q: White Light Flashes in Vision: Causes and Solutions

Hello： Based on your description, it sounds very much like floaters, which are impurities in the vitreous body. <br>It should not be a cause for concern, but I recommend that you visit an ophthalmologist for a dilated eye examination.

There is a sensation of white light obstructing vision in the eyes?

Hello, Doctor! I have been experiencing eye issues for about 3 to 4 months.
Initially, I noticed a flash of white light at the outer corner of one eye, which later switched to the other eye.
Recently, the flashes have stopped, and instead, I occasionally see a white oval shape obscuring my vision below both eyes for about 1 second.
The frequency of these occurrences is quite variable (afterward, I do not notice any change in my vision).
I have also observed that this issue seems to occur more frequently when I am sitting cross-legged on the bed or leaning forward in a chair, especially when looking at a screen, while it hardly happens when I am standing or walking.
Additionally, I have dry eye syndrome, and I experience inflammation and soreness around my brow and eye sockets, along with occasional sharp pain in my eyeballs.
During this period, I consulted both an ophthalmologist and a neurologist.
The ophthalmologist performed a slit-lamp examination and checked my intraocular pressure (which was 16) and found no issues, ultimately prescribing me an ointment containing vitamin A.
The neurologist examined my optic nerve and also found no problems.
I have read various articles, and it seems that most people describe seeing tiny star-like lights, but my experience feels more like a solid white object briefly obstructing my vision before disappearing.
I am unsure what could be wrong with my eyes.
Although the frequency may have decreased, the problem persists and seems to shift locations.
Should I continue to see an ophthalmologist or seek a referral? Thank you for reading this.

More Info

The phenomenon of experiencing white light flashes in your vision can be concerning, especially when it occurs frequently or changes in nature. Based on your description, it seems that you have been experiencing these flashes for several months, with variations in their occurrence depending on your posture and other factors. Let's delve into the potential causes and solutions for this issue.

Understanding the Causes
1. Vitreous Detachment: One of the most common causes of flashes of light, particularly in individuals with myopia (nearsightedness), is vitreous detachment. The vitreous gel that fills the eye can shrink and pull away from the retina, leading to sensations of light flashes. This is often accompanied by floaters, which you mentioned you have.

2. Retinal Issues: Although you have had examinations that ruled out retinal tears or detachments, it is crucial to remain vigilant. Flashes can sometimes indicate that the retina is being stimulated due to traction from the vitreous. If you experience an increase in the frequency or intensity of these flashes, or if you notice a sudden increase in floaters, it is essential to seek immediate medical attention.

3. Ocular Migraines: Another possibility is ocular migraines, which can cause transient visual disturbances, including flashes of light or zigzag patterns. These typically resolve within a short period and are often not accompanied by pain. However, they can be confusing, especially if they occur alongside other symptoms.

4. Dry Eye Syndrome: Given your mention of dry eyes, this condition can also contribute to visual disturbances. Dryness can lead to irritation and inflammation, which might cause transient flashes or other visual anomalies. The discomfort you feel around the eyes could be exacerbated by dry eye syndrome.

5. Postural Changes: You noted that the flashes occur more frequently when you are seated or leaning forward. This could be related to changes in intraocular pressure or the position of the vitreous gel within the eye. Certain postures may increase the likelihood of vitreous traction on the retina, leading to flashes.

Recommendations
1. Continued Monitoring: Since you have already consulted with both ophthalmology and neurology, it is advisable to continue monitoring your symptoms. Keep a detailed log of when the flashes occur, their duration, and any associated symptoms. This information can be invaluable for your healthcare provider.

2. Regular Eye Exams: Regular follow-ups with your ophthalmologist are essential, especially given your history of myopia and dry eye. Even if previous examinations have shown no issues, changes in your symptoms warrant re-evaluation.

3. Consider a Referral: If your symptoms persist or worsen, discussing a referral to a retinal specialist may be beneficial. They can perform more specialized tests to assess the health of your retina and vitreous.

4. Manage Dry Eye Symptoms: Since you have dry eye syndrome, consider using artificial tears or other lubricating eye drops to alleviate discomfort. Discuss with your eye care provider about potential treatments, such as punctal plugs or prescription medications, to manage your dry eye symptoms effectively.

5. Lifestyle Adjustments: Pay attention to your posture and try to maintain a neutral position while using screens or reading. Frequent breaks and proper hydration can also help manage dry eye symptoms.

Conclusion
In summary, the white light flashes you are experiencing could be attributed to several factors, including vitreous detachment, retinal issues, ocular migraines, or dry eye syndrome. Given your history and the complexity of your symptoms, it is crucial to maintain open communication with your healthcare providers and continue monitoring your condition. If you notice any significant changes or worsening symptoms, do not hesitate to seek immediate medical advice. Your eye health is paramount, and proactive management can help mitigate potential complications.
