Eye Flashes: Causes and Concerns for High Myopia Patients - Ophthalmology

Hello,
Thank you for your inquiry regarding the experience of eye flashes and increased floaters, especially in the context of high myopia. Your symptoms are indeed concerning, and it’s important to understand the potential causes and implications associated with them.

High myopia, or severe nearsightedness, can lead to various ocular complications, including changes in the vitreous body (the gel-like substance in the eye) and the retina. The flashes of light you are experiencing, particularly after coughing or straining, may be related to the vitreous pulling on the retina. This phenomenon is often referred to as "photopsia," which is the perception of flashes of light. It can occur when the vitreous gel begins to liquefy and detach from the retina, a process known as posterior vitreous detachment (PVD). This is more common in individuals with high myopia due to the elongation of the eyeball, which can lead to increased tension on the retina.

The increase in floaters you mentioned is also a common occurrence associated with changes in the vitreous. Floaters are tiny clumps of gel or cells that float in the vitreous and can cast shadows on the retina, leading to the perception of spots or strands in your vision. While floaters are often benign, a sudden increase in their number, especially when accompanied by flashes of light, warrants careful evaluation to rule out more serious conditions such as retinal tears or detachment.

Given your history of high myopia and the recent onset of these symptoms following a bout of coughing, it is advisable to seek a thorough examination from an ophthalmologist. They may perform a dilated eye exam to assess the health of your retina and vitreous. This examination can help determine if there are any tears or other changes that require intervention.

In terms of management, if your symptoms are stable and there are no signs of retinal detachment or other serious issues, your doctor may recommend regular monitoring. However, if you experience any new symptoms, such as a sudden increase in flashes or floaters, a shadow or curtain effect in your vision, or any significant changes in your visual acuity, you should seek immediate medical attention.

Additionally, it’s important to manage any underlying health issues, such as stress or anxiety, which can exacerbate your perception of visual disturbances. Ensuring adequate rest, hydration, and nutrition can also support overall eye health.
In summary, while flashes and floaters can be common in individuals with high myopia, the recent changes you’ve experienced, particularly after coughing, should be evaluated by a professional. Regular follow-ups with your eye care provider are essential to monitor your condition and ensure timely intervention if necessary. Please do not hesitate to reach out to your ophthalmologist for further evaluation and peace of mind.

Best wishes for your eye health and overall well-being.
