Case of the Month 08/10

This 58 year old female presented complaining of left eye pain after head trauma.

Question 1: What's wrong with this picture?

View answer

Answer 1:

This CT reveals a posterior dislocation of the left lens (see arrow below.)

Question 2: What causes this and how does it present?

View answer

Answer 2:

Lens dislocation (which can be either anterior or posterior) usually is the result of a congenital condition (such as homyocystinuria or Marfan’s syndrome) or direct trauma. It presents with marked visual blurring. A helpful exam finding is shimmering of the iris with rapid eye movement due to movement of the dislocated lens.

Question 3: If this diagnosis is suspected, what are your imaging options?

View answer

Answer 3:

Ultrasound or CT scan may be used to make this diagnosis if it is not apparent on fundoscopic exam. Treatment options range from observation only to surgical removal.
