Abstract Details

Purpose:

To report a case of a 73-year-old female patient victim of blunt trauma that resulted in multiple fractures of temporal and orbital bones, with consequent traumatic mydriasis and lens dislocation to the anterior chamber, detected 4 months after the trauma.

Setting:

Ophthalmology Department, Hospital de Santa Maria - Centro Hospitalar Lisboa Norte, Portugal

Methods:

Case Report. The patient was submited to head and orbit computed tomography, ophthalmic exam, anterior segment photographs, pentacam, specular microscopy, ocular ultrasonography and macular optical coherence tomography.

Results:

The patient presented to the ophthalmology office with a 4 month history of painless reduction of vision of the left eye, after violent blunt trauma to the head and left orbit. The lens was completely dislocated to the anterior chamber, lightly touching the corneal endothelium, without corneal edema, intraocular hypertension or inflammation. The patient was submited to intracapsular cataract extraction and implantation of an iris fixation retropupilar intraocular lens. The best corrected visual acuity improved from counting fingers to 20/100 one month after surgery.

Conclusions:

We present a rare case of traumatic anterior chamber lens dislocation without consequent corneal edema, intraocular hypertension or inflammation. One month after surgery, the best corrected visual acuity increased only to 20/100, probably due to the high induced astigmatism and the corneal edema secondary to the surgery. Light sensivity could be improved with iridoplasty and vision improvement is expected to occur after recovery of cornea edema.
