Traumatic Cataract

Eye injuries occur very often especially in case of children (when they play, when they practice sports). Males are more prone to injuries and to traumatic cataract than females.

Traumatic cataract may also appear if the patient suffered in the past an eye surgery or diabetes, sulfate oxides deficiency, hyperlysinemia.

The diagnose is set after an ophthalmic examination that may include (depending on each particular case): the observation of the fundus in order to find retinal detachment or hemorrhage, or problems of the optical nerve; also the pupils are checked and the lenses integrity. Possible studies in this case are : A-scan, and CT scan for the orbits.

Children that practice aggressive sports are advised to use protective eyewear in order to avoid injuries and traumas. It is better to try to prevent traumatic cataract than to treat it, especially because complication may appear. Retinal detachment can happen or lens dislocation, the chorodial can rupture, hemorrhages may start at the retrobulbar level. It’s hard to describe the outcome of traumatic cataract because this depends on each case of injury .

The treatment depends on each particular case. If the lens are subluxated, then miotics may help. It may also help when the visual axis is close to the cataract . If the patient has glaucoma then the intraocular pressure must be kept under control with medications.

Surgery is not necessary in the case of inflammation and dislocation without glaucoma, but it will be performed when the patient presents : glaucoma, when capsular rupture appears and the lens are swelling, a high decreased vision. . An phacoemulsification is recommended when the capsule is intact but when the lens was prior dislocated then intracapsular cataract extraction is needed and as soon as possible because it may lead to pupillary block glaucoma.

After a strong blow when the lens is subluxed other problems may appear :astigmatism, myopia, and different powers of the lens between an eye and the other. They will certainly cause unclear vision and possible an ” lazy eye”
