Description

Trauma to the eye may result in damage to the crystalline lens, its capsules and/or supporting structures. If this damage results in an inflammatory response, then additional damage to the eye may develop.


 

Cataract and opacification of the lens:

(1) contusion cataract (partial or localized opacification following blunt trauma)

(2) rosette cataract (a type of contusion cataract causing visual impairment, with a central "rosette" radiating from the central nuclear sutures)

(3) injury to the anterior capsule with partial or complete lenticular opacification

(4) Soemmering ring cataract (remnant of the lens capsule and cortex that remains after resorption of the lens)

(5) intralenticular foreign body (may be relatively inert or result in lens opacification)

(6) rupture of the posterior capsule (may result in lens opacification)

 

Displacement:

(1) subluxation of the lens (following a partial zonular dehiscence)

(2) dislocation of the lens (following a complete zonular dehiscence, with forward displacement of the lens)

 

Other:

(1) lenticular glaucoma (glaucoma caused by (a) inflammation following release of lenticular material into the anterior chamber or (b) anterior displacement of the lens)

(2) lens involution (aphakia following an inflammatory response caused by a laceration of the anterior lens capsule)

(3) Vossius ring (pigment from the pupillary border onto the anterior surface of the lens after contusion injury)
