Traumatic Cataract

Most common complication of non-perforating and perforating injuries to the globe. Intraocular trauma by surgical instruments, lodged foreign body or intraocular filtration tube is also a possible cause. Clinical features: Cataract formation after non-perforating injuries such as contusion or concussion may occur without any damage to the lens capsule The cataract formation may be slowly progressive or mature suddenly It is not always easy to observe initial changes of the lens Vossius' ring can be seen as circular iris pigment imprinted on the surface of the lens anterior capsule Opacification can occur in a variety of lens structures resulting in discrete, punctate subepithelial changes, or deep in the cortex with the typical rosette (flower-shaped) opacity Trauma may also produce anterior or posterior subcapsular opacities.
