What is retinal detachment? It is the separation of the retinal nerve epithelium from the pigment epithelium by the accumulation of fluid between the retinal nerve epithelium and the pigment epithelium. What are the types of retinal detachment? Pore-derived retinal detachment, retinal retinal detachment with retraction, retinal detachment with exudation Which is the most common type of retinal detachment? Pore-derived retinal detachment What are the symptoms of pore-derived retinal detachment? In retinal detachment, the following symptoms may be present: flashing sensation, black shadows in front of the eyes, loss of vision, and distortion of vision. What factors may increase a patient’s chance of developing the disease? Myopia, especially moderate to high myopia, has a high chance of retinal degeneration and heavy vitreous liquefaction, so the chance of retinal detachment is higher than normal. The chance of retinal detachment is also increased in people with retinal degeneration areas on fundus examination, cataract surgery, trauma, and foraminogenic retinal detachment in the contralateral eye. Patients with these risk factors should have regular fundus examinations and pay attention to changes in symptoms such as floaters and dark shadows in front of the eyes and seek timely medical attention.
