The incidence of these lens opacities is
higher in men than in women due to occupational and sports injuries. The
following types of traumatic cataracts are differentiated:
❖ Contusion cataract: Contusion of the eyeball will produce a rosette-shaped subcapsular opacity on the anterior surface of the lens. It will nor-mally remain unchanged but will migrate into the deeper cortex over time due to the apposition of new fibers (Fig. 7.13).
❖ Infrared radiation cataract (glassblower’s cataract): This type of cataractoccurs after
decades of prolonged exposure to the infrared radiation of fire without eye
protection. Characteristic findings include splitting of the anterior lens
capsule, whose edges will be observed to curl up and float in the anterior
chamber. Occupational safety regulations have drastically reduced the incidence
of this type of cataract.
❖ Electrical injury: This dense subcapsular cataract can be caused bylightning or
high-voltage electrical shock.
❖ Cataract from ionizing radiation
