Sudden White Light and Sounds When Closing Eyes: Causes and Concerns - Ophthalmology

Share to:

Sudden flashes of white light when closing your eyes at night could be a phenomenon known as "phosphenes." These are visual sensations that occur without light actually entering the eye, often caused by pressure on the retina or spontaneous activity in the visual system?


Hello Doctor,
Recently, I underwent a vitrectomy with silicone oil tamponade and laser photocoagulation due to retinal detachment.
It has been almost a month since the surgery.
However, in the past few days, I have experienced sudden flashes of white light (lasting about a second) when I close my eyes to sleep or rest.
Sometimes, while sleeping, I also hear sudden sounds accompanied by the white light, which startles me.
As a result, I feel anxious when trying to sleep or rest with my eyes closed.
I am concerned and wonder if this could be related to a worsening of my condition.
Could you please provide some clarification? Thank you.

Hello Mr.
Wu: This may be an electrical response of the retina.
Since silicone oil has been injected, it should be more stable.
However, if you are still concerned, it would be best to have it checked.

Hello! Thank you for reaching out with your concerns regarding the sudden appearance of white light and sounds when closing your eyes, especially after undergoing vitrectomy and retinal laser treatment. It's understandable to feel anxious about any new symptoms following such significant eye surgery.

First, let's address the phenomenon of seeing white light when your eyes are closed. This experience can be attributed to several factors, particularly in the context of your recent surgery. After vitrectomy, the eye undergoes various changes as it heals, and the presence of silicone oil can also influence visual perception. The white light you are experiencing may be a form of visual phenomenon known as "phosphene," which occurs when the retina is stimulated by pressure or movement, even in the absence of light. This can happen when you close your eyes, especially if there is any residual tension or movement in the vitreous gel or surrounding structures.

Additionally, the sudden sounds you mention could be related to a heightened state of awareness or anxiety, particularly if you are feeling tense or worried about your eye condition. It's not uncommon for individuals recovering from eye surgery to experience increased sensitivity to sensory stimuli, including sounds and visual phenomena. This heightened sensitivity can lead to a perception of sounds that may not be present or are more pronounced than usual.

Given your history of retinal detachment and the recent surgical intervention, it is crucial to monitor any new symptoms closely. While the experiences you describe may be benign, they could also indicate changes in your eye condition that warrant further evaluation. For instance, if the white light becomes more frequent, persistent, or is accompanied by other symptoms such as flashes of light, an increase in floaters, or changes in vision, it would be advisable to consult your ophthalmologist promptly. These could be signs of complications such as retinal tears or further detachment, which require immediate attention.

In the meantime, here are a few recommendations to help manage your anxiety and monitor your symptoms:
1. Keep a Symptom Diary: Document when the white light and sounds occur, their duration, and any associated activities or feelings. This information can be helpful for your doctor during follow-up visits.

2. Practice Relaxation Techniques: Engaging in relaxation exercises, such as deep breathing or mindfulness meditation, can help reduce anxiety and improve your overall sense of well-being.

3. Follow-Up Appointments: Ensure you attend all scheduled follow-up appointments with your ophthalmologist. Regular monitoring is essential after retinal surgery to assess healing and detect any potential issues early.

4. Limit Eye Strain: Avoid activities that may strain your eyes, such as prolonged screen time or reading in dim light, especially if you notice increased symptoms during these activities.

5. Stay Informed: Educate yourself about the recovery process and potential symptoms to expect after your surgery. Understanding what is normal can help alleviate some of your concerns.

In conclusion, while the sudden appearance of white light and sounds when closing your eyes can be alarming, it is often related to the healing process following your surgery. However, it is essential to remain vigilant and consult your ophthalmologist if you notice any changes or worsening of your symptoms. Your eye health is paramount, and addressing any concerns with a professional will provide you with the best guidance and peace of mind. Wishing you a smooth recovery and good health!
