Which etiologic category includes exposure to radiation or electric shock as a cataract risk?

• A. Trauma
• B. Metabolic
• C. Radiation and electric shock
• D. Nutritional

Answer: (C)

Exposure to radiation or electric shock injures the lens by delivering energy that denatures crystallins and disrupts the orderly arrangement of lens fibers, leading to opacification. This type of injury is grouped under radiation and electric shock cataract etiologies because it arises from external energy exposure rather than a systemic metabolic disturbance, nutritional deficiency, or a direct mechanical trauma to the eye. Ionizing radiation exposure increases cataract risk in a dose-dependent way, and electric shock can cause lens damage as part of an ocular injury. In contrast, trauma implies a physical wound to the eye, metabolic refers to diseases like diabetes that alter lens metabolism, and nutritional covers deficiencies affecting lens components. Thus, exposure to radiation or electricity fits best in the radiation and electric shock category.
