What is the clinical manifestation of lens ectopia and dislocation?

summary

Lens dislocation is a very common disease. Generally speaking, the normal lens is suspended in the ligament above the ciliary body, and its axis is almost the same as the optic axis. However, sometimes because of external injury or some diseases in the body, it will cause lens dislocation. What are the clinical manifestations of lens ectopia and dislocation? Now let me tell you something.

What is the clinical manifestation of lens ectopia and dislocation?

The early symptoms of lens dislocation are: 1. Incomplete dislocation of lens: the displaced lens is still in the pupil, in the vitreous cavity of the plane behind the iris. The condition of incomplete dislocation of lens is completely determined by the degree of lens displacement. If the static axis is still above the optic axis, then the suspensory ligament will be loose, which will cause crystalline myopia. If the crystal axis is shifted, then severe astigmatism will appear. 2. Total dislocation of the lens: the displaced crystal is completely separated from the pupil area, and the crystal will be displaced or produced.

There are three main causes of lens dislocation: 1. Traumatic lens dislocation: external injury to the eyes, especially blunt injury to the eyeball, is the most common cause of lens dislocation. Because traumatic lens dislocation is often caused by secondary cataract. 2. Lens suspensory ligament is damaged or broken: Generally speaking, the lens will be suspended above the ciliary body in the lens suspensory ligament, and the axis of the lens is almost the same as the optic axis. However, if the suspensory ligament of the lens is damaged or broken, it will cause the complete displacement of the crystal.

Spontaneous lens dislocation: spontaneous lens dislocation is caused by the mechanical side length of the suspensory ligament caused by lesions in the eye, or by the decomposition and degeneration of inflammation. Lens dislocation due to mechanical elongation of the suspensory ligament is usually caused by bovine eye, staphyloma or eyeball expansion.
