Retinal detachment is one of the common retinal diseases, and its key disease is shadow occlusion near the early line of sight. If not treated immediately, the scope of retinal detachment will gradually expand, and the total area of shadow will also increase. When the development trend of retinal detachment reaches the macular area, it will cause the visual acuity of the eyes to decrease obviously, which will eventually lead to high intraocular pressure and eyeball aging. There are three key factors of retinal detachment: first, rhegmatogenous retinal detachment, lack of position near the retina, resulting in partial dry hole cracking or lattice deformation, and liquid enters the lower part of the retina according to the above areas, separating the retina from the eyeball wall, resulting in retinal detachment. Second, exudative retinal detachment, considering the capillary leakage of choroid plexus caused by uveitis, a large amount of leakage liquid stagnated under the retina, causing retinal detachment. Third, traction retinal detachment, considering the production of organic chemical film in front of retina, involves retinal detachment.

When injured, the eyeball can be temporarily deformed at the moment of collision with fitness exercise. Although the eyeball wall can meet the external force, the vitreous body can't. At this time, the basal end of vitreous body is separated from the ball wall, which is easy to cause degloving injury of serrated edge of retina. Hole-breaking trauma can cause retinal detachment at the same time, and middle and late vitreous regeneration can cause traction detachment. People with vitreous diseases in cataract surgery are very prone to retinal detachment, and the increase of vitreous cavity increases the indoor space of vitreous sloshing and improves its driving force to retina, which is very prone to retinal detachment.

Rhegmatogenous retinal detachment is common in the elderly, due to high myopia, aphakia, intraocular lens, eye trauma and other reasons. Traction retinal detachment is common in proliferative diabetic retinopathy, retinopathy of prematurity, capillary retinopathy with vitreous congestion and eye trauma. The key to exudative retinal detachment is serous retinal detachment and hemorrhagic retinal detachment, both of which have no retinal breaks. The key to serous retinal detachment is Harada disease, uveitis and posterior sclera, the latter is more common in wet macular degeneration and eye trauma. Retinal detachment is mainly the detachment of retinal melanin epithelial tissue and nervous system epithelial tissue, which can be divided into rhegmatogenous retinal detachment, traction retinal detachment and exudative retinal detachment. When retinal detachment occurs, we must first make clear what kind of detachment it belongs to and treat the cause.

There are three main types of retinal detachment. One is that there is a hole in the retina, which may be due to age and high myopia, or there is a hole in the retina after trauma, and the water in the eye leaks behind the retina according to the hole, and the retina falls off from the inner wall of the eyeball. This retinal detachment is called rhegmatogenous retinal detachment. There is also a traction retinal detachment, because the mechanism next to the retina is called vitreous body. This vitreous body is a sticky thing, which is filled in the eyeball to support the retina. When the vitreous pulls the retina, it is very likely that the retina will be pulled out, or the genital membrane will be pulled out because of eye diseases. There is also a kind of detachment, called exudative detachment, which is related to the rupture and inflammation of ocular capillaries, and also makes the retina separate from the inner wall of the eyeball.
