Indirect trauma causing dislocation of the crystalline lens--a case report.

PURPOSE: To report a case of indirect trauma causing dislocation of the crystalline lens in a patient with no underlying risk factors.

METHODS

Case report.

RESULTS

A 76-year-old woman fell injuring her right temple area. She complained of blurring of vision in her right eye. Her vision was reduced to 6/60. Ocular examination revealed right aphakia associated with complete posterior dislocation of the crystalline lens into the vitreous cavity. No predisposing factors as pigment dispersion or pseudoexfoliation material was found on gonioscopy.

CONCLUSIONS

Dislocation of the crystalline lens has been reported following direct trauma. It is known to occur spontaneously in mature and hypermature cataracts and in cases of weak zonules. Our case shows that indirect trauma can cause complete dislocation of the crystalline lens in the absence of any predisposing factors.
