11 Lens and Cataract
Chapter 5: Pathology
Electrical shock can cause protein coagulation and cataract formation. Lens manifestations are more likely when the transmission of current involves the patient’s head. Initially, lens vacuoles appear in the anterior midperiphery of the lens, followed by linear opacities in the anterior subcapsular cortex. A cataract induced by an electrical injury may regress, remain stationary, or mature to become a complete cataract over months or years (Fig 5-18).
