EYE DISEASES : LENS DISLOCATION AND SUBLUXATION OF THE LENS (LUXATIO ET SUBLUXATIO LENTIS) - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
Congenital subluxation of the lens is due to uneven development Zinovii ligament; acquired - caused by breaks when contusions of the eye. Dislocation develops or subluxation of, or immediately when severe contusions.
Symptoms. When subluxation in the pupil visible edge of the lens, especially good in sensing eye mirror; it looks like a curved dark line. In dislocation of the crystalline lens or offset in the anterior chamber or in the vitreous, where it can be discovered.
For. Subluxation gradually increases and can go into dislocation. Congenital subluxation of the lens, usually bilateral. Dislocation into anterior chamber is always complicated by glaucoma; dislocation into the vitreous body can lead to the iridocyclitis (see) or glaucoma (see).
Recognition is not difficult.
When subluxation of the lens, if the vision is improved from the glass, the appointment of the relevant points; if not improved by the surgery. In dislocation of the lens in the anterior chamber - the surgical removal; if the whole lens into the vitreous body, the removal is more difficult and often leads to serious complications, so if there is no formidable phenomena, it is better to confine symptomatic treatment, depending on the eye condition (glaucoma - pilocarpine, in iritis - atropine, leeches).
