What are the symptoms of cataract?

summary

After extracapsular cataract extraction or lens trauma, the residual cortex and epithelial cells on the posterior capsule proliferate and form a translucent membrane in the pupil area, which is called posterior cataract. With the popularization of aspiration, extracapsular surgery and phacoemulsification, posterior cataract is more common. What are the symptoms of cataract? Let's talk about it

What are the symptoms of cataract?

During contusion, the iris pigment epithelium at the edge of the pupil ruptures and falls off, and adheres to the anterior surface of the lens, which is called vossius ring opacification. The corresponding opacification appears under the capsule, which can disappear after a few days or exist for a long time.

When the lens is contused, the structure of its fiber and suture is destroyed, and the fluid flows towards the suture space and lamella of the lens, forming radial turbidity, which can occur within a few hours or weeks after injury, and can be absorbed or exist permanently.

Severe contusion can lead to rupture of lens capsule, especially posterior capsule, and aqueous humor entering into lens body. When the tear is small, the lens can be completely turbid in a short time. Ocular contusion can cause anterior chamber hemorrhage, anterior chamber angle recession, lens dislocation and secondary glaucoma.
