Choroidal laceration

The choroid is between the retina and sclera, which is rich in blood vessels and pigment cells. It is less resistant to external force shocks than the retina. When the eyeball is impacted by external force from the front through the vitreous body to the posterior pole, the hard sclera is in the It has a resistive effect on the outside, which causes the choroid to rupture and bleed when it is attacked by both internal and external effects. The degree of affected vision varies depending on the location of the rupture. If the rupture is located in or around the macula, central vision can be severely damaged.
