It’s a good retina.
It’s just gone off!
Myopia is only 200 degrees.
There are always shadows and ripples in front of my eyes.
Cough a little harder for a cold.
I can’t see a thing!
Is “net loss” an alarmist theory?
Or is it really an invisible killer?
01 What is Retinal Detachment
The retina is the equivalent of the light-sensitive film in a camera. It is responsible for receiving light stimuli from the outside world and transmitting signals to the brain to produce the clear images we see.
The retina is a complex, transparent membrane that is attached to the back wall of the eye and consists of a neuroepithelial layer and a pigmented epithelial layer. If a separation occurs between these two layers, we call it a retinal detachment. The detached retina is unable to perceive light stimuli, resulting in the eye receiving incomplete or missing images.
02 Is retinal detachment only possible with high myopia?
Myopia is a high risk factor for retinal detachment, especially high myopia, and the higher the refraction, the higher the risk. It does not mean that retinal detachment will not occur in patients with lower levels of myopia.
The myopic eyeball is longer than the normal eyeball length. When the refractive error of the eyeball increases, the eye axis lengthens, and the posterior eyeball wall gradually expands, the retina at the bottom of the eyeball will become thinner, and the weaker areas around the periphery will be pulled out of the hole, forming a retinal tear, which will in turn pull on the retina and easily lead to retinal detachment. This is related to congenital factors such as retinal elasticity.
Therefore, patients with low to moderate myopia should also have their fundus examined regularly, including the peripheral fundus.
03 Colds and coughs can cause retinal detachment?
Violent coughing will make the liquefied vitreous body to the retina caused by a certain impact force, if at this time the retina has appeared on the deformation or cracked area, from the vitreous body of the liquid can be through the retinal cracks into the retina, may lead to retinal detachment.
04 Symptoms of retinal detachment
Before retinal detachment occurs in most people, there will be a fluttering black shadow in front of the eyes, which gradually worsens, and a flashing sensation, i.e., a phenomenon similar to a discharge flash, will also occur.
With the occurrence and progress of detachment, there will be a fixed curtain-like black shadow blocking in a certain direction of the visual field, and the scope of the black shadow gradually increases, which can be extended to the center of the visual field, and ultimately, the visual acuity will be severely reduced, and even the eyeball will atrophy and become blind.
05 How to prevent?
- Avoid over-exertion of the eyes, pay attention to the combination of work and rest, prevent myopia, especially high myopia, and have regular refractive examinations.
- For high-risk groups, it is recommended that routine dilated pupil examination of the fundus should be performed every six months to one year, and laser closure of retinal tears or degeneration areas can be performed for early detection.
- Patients with high myopia or recently completed laser closure of retinal tears should avoid strenuous exercise and heavy labor to avoid triggering the occurrence of retinal detachment.
- Prevent eye trauma.
- actively control the primary disease, such as high blood pressure, diabetes, uveitis, etc. 6.
- Consult the doctor as soon as possible once the flashing sensation or blurred vision is detected.
