The retina is made up of multiple layers of cells. When the [neuroepithelial layer] and [pigment epithelial layer] of the retina are separated, it is called [retinal detachment]. Since the shedding of the retina loses its visual function due to loss of nutrient supply, if it is not treated promptly and properly, vision may be permanently damaged by cell shrinkage on the retina, leading to blindness.
Causes of retinal detachment:
- 1) Primary:
- Most of the causes are related to deep myopia, heredity, degeneration and vitreous liquefaction. When the retina becomes thin and degenerates with small holes or cracks, the retina will fall off due to the weight of the liquid in the eyeball.
- 2) Secondary:
- Caused by trauma, severe inflammation in the eye, tumors and proliferative retinopathy.
- 1) People with deep myopia (more than 600 degrees)
- 2) Close relatives have had a history of retinal detachment
- 3) Eyes hurt
- 4) Flash constantly
- 5) There are other problems in the body, such as Marfan Syndrome, improper diabetes control, etc.
- 1) Flash
- 2) See small dots of different shapes (commonly known as "flying mosquitoes")
- 3) Sudden vision loss or cloud occlusion
- 4) Lost part of the field of view
- 5) If the retinal detachment occurs in the macula, the central visual acuity will be greatly reduced, and the phenomenon of scene deformation may occur.
Patients with retinal detachment are not red or painful, and the degree of vision loss is related to the location of the retinal detachment, the range of time, and the degree of vitreous opacity.
Retinal detachment is a serious ophthalmic emergency. Because the chance of natural comfort after retinal detachment is very small, patients must receive appropriate treatment, otherwise there will be a chance to cause permanent visual impairment.
