Complications of ectopic and dislocated lens

Common complications: cataract, ametropia and malignant glaucoma

Complications of ectopic and dislocated lens

In addition to serious ametropia, lens dislocation often produces some serious complications.

1. Uveitis

It is a common complication of lens dislocation. There are two kinds of uveitis caused by lens dislocation. One is that uveal tissue is caused by mechanical stimulation of lens, and the other is that dislocated lens becomes overmature cataract. Allergic uveitis with crystals. Both types of uveitis are intractable inflammation and can lead to secondary glaucoma.

2. Secondary glaucoma

It is also one of the most common complications. Pupil block glaucoma can occur when the lens is detached from the pupil area or vitreous hernia is incarcerated in the pupil. Repeated pupil block can make iris bulge and produce aphakic malignant glaucoma. Long-term dislocation of lens can produce lens-soluble glaucoma. In addition, lens dislocation caused by ocular contusion can be combined with iris root recession and angle splitting, resulting in secondary glaucoma.

3. Retinal detachment

It is the most common and serious complication of lens dislocation, especially in eyes with congenital anomalies, such as Marfan syndrome, and even binocular. The treatment of retinal detachment caused by lens dislocation is difficult, because dislocated lens often hinders finding the accurate position of retinal tear and the range of retinal detachment. If the lens is removed first, it will make vitreous body lose, aggravate retinopathy and delay the time of retinal detachment reattachment operation.

4. Corneal opacity

In recent years, it has been noticed that dislocation of lens can cause corneal opacity. After dislocation of lens into anterior chamber, it contacts with corneal endothelium, which leads to damage of corneal endothelial cells and corneal edema and turbidity.
