Retinal detachment is more common in spring
Published on
Spring brings more outdoor activity and increased allergies, factors that can increase the risk of retinal detachment. But why does this happen, and how can we prevent it? In this article, we explain everything you need to know to protect your eye health this season.
What is retinal detachment?
Retinal detachment is a serious eye condition in which the retina separates from the choroid. Without treatment, it can cause irreversible vision loss.
Why is retinal detachment more common in spring?
There are several reasons why this condition is more common in spring. Let us look at them in detail:
1. Greater exposure to sunlight
The pupil contracts when we are exposed to the sun. This pupillary contraction, stimulated by light, is an automatic mechanism regulating the amount of light entering the eye and reaching the retina. The more light there is, the greater the contraction, and sunlight is one of the strongest stimuli, much more powerful than artificial lighting.
When the pupil contracts suddenly and strongly, the ciliary body is pulled forwards, taking the vitreous humour with it. This sudden contraction can cause the vitreous humour to separate from the retina, which in predisposed people could cause tears, and therefore the possibility of retinal detachment.
Although no conclusive studies demonstrate this relationship, our clinical experience confirms it. In Castellón, when the sun shines intensely, we see more patients noticing the sudden appearance of black spots or floaters. In many cases, this is due to vitreous detachment.
It is estimated that around 10% of people with symptomatic vitreous detachment may have a retinal tear or break. If not detected and treated in time, this could progress to retinal detachment, a serious condition that threatens vision.
2. Increased physical activity and sport
Impact sports, such as football, cycling or tennis, can cause eye trauma that triggers retinal detachment.
3. Allergies and excessive eye rubbing
Spring allergies make the eyes itch more, leading to excessive rubbing, which could change intraocular pressure, creating traction of the vitreous on the retina and potentially causing a retinal tear.
Warning signs: how can retinal detachment be detected?
If you notice any of these symptoms, see an ophthalmologist immediately:
- Flashes of light (photopsia).
- Sudden appearance of floaters.
- Blurred vision or the sensation of a “black curtain”
Who is at greater risk in spring?
- People with high myopia (>6 dioptres).
- People who play sport and active individuals.
- Patients with a history of eye surgery (cataracts, retinal laser treatment).
- Patients with inflammatory eye diseases (uveitis).
Prevention: how can you protect your eyesight in spring?
- Wear sunglasses with a UV filter
- Avoid rubbing your eyes and use artificial tears.
- Have regular ophthalmic check-ups, especially if you have high myopia.
- Protect your eyes during contact sports with specialist glasses.
Retinal detachment can occur at any time, but certain factors increase the risk in spring. Protect yourself, have your eyes checked and act on any symptoms.
