The ophthalmologist named the cause of short-term flashes when sneezing

Short-term flashes or sparks that occur when sneezing are in most cases a normal physiological phenomenon. The nature of the occurrence of visual phenomena during sneezing on September 10 was explained to Izvestia by an ophthalmologist, ophthalmic surgeon at JSC "Medicine" (Academician Roitberg Clinic), Candidate of Medical Sciences Sino Goziev.

"These optical effects, known as phosphenes, are a subjective sensation of light without a real external source and occur due to mechanical or electrical stimulation of the retina, optic nerve, or cortical visual centers of the brain. When sneezing, there is a sharp increase in intra—thoracic and intra-abdominal pressure, which is briefly transmitted to the vessels of the brain and eyeballs," the doctor explained.

He clarified that this causes micro-vibration of the retina or a change in blood flow, which leads to short-term flashes. If phosphenes occur only when sneezing, coughing, or sudden movement, last less than 1-2 seconds, and are not accompanied by pain, loss of vision, or floating opacities, then this is considered a variant of the norm.

However, as Dr. Goziev emphasizes, there are alarming signs that require immediate medical attention. If the flare-ups become more frequent, intense, or prolonged, appear spontaneously without provoking factors, or are accompanied by other symptoms such as headache, nausea, or decreased vision, this may indicate serious pathologies. Among the possible problems, the specialist identifies retinal detachment, posterior vitreous detachment, increased intracranial pressure, glaucoma and migraine with aura.

Special attention should be paid to patients with high degree of myopia, who have suffered head or eye injuries, as well as those suffering from retinal degenerative changes. Dr. Goziev recommends regular routine checkups with an ophthalmologist, especially after the age of 40, blood pressure monitoring and avoiding sudden head movements for those who are predisposed to retinal problems.

As preventive measures, the specialist advises maintaining a healthy weight, regular physical activity, avoiding prolonged exertion, quitting smoking and limiting alcohol consumption. It is also important to maintain water balance and treat infections of the ENT organs in a timely manner, as chronic runny nose and frequent sneezing can worsen symptoms.

In conclusion, Dr. Goziev notes that although phosphenes are harmless in most cases when sneezing, any changes in visual sensations require careful attention. A timely examination by an ophthalmologist and neurologist can preserve vision and prevent the development of dangerous complications.

Earlier, on July 9, Anna Solovey, ophthalmologist at the 3Z clinic, reported that sunglasses can be an excellent eye protection against allergic conjunctivitis. In case of eye inflammation, the doctor recommends contacting a specialist who will prescribe the right treatment.
