A 9-year-old girl witnessed the violent murder of a close family member. She now says she is blind. However, she flinches when objects are quickly moved toward her face. There is no neurologic evidence of blindness. What is the most likely diagnosis?

Choice A reason: Factitious disorder involves intentionally producing or feigning symptoms to assume the sick role, usually for attention. This child is not deliberately faking blindness; it is a subconscious response to trauma. Choice B reason: Illness anxiety disorder involves excessive worry about having or acquiring a serious illness without significant somatic symptoms. The child’s symptoms are not due to health anxiety. Choice C reason: This is the correct answer. Conversion disorder involves neurologic symptoms, such as blindness, paralysis, or seizures, without a medical explanation, often triggered by psychological stress. The flinching reflex indicates intact vision despite reported blindness, consistent with conversion disorder. Choice D reason: Somatic symptom disorder involves distressing somatic symptoms that cause significant impairment but are not intentionally produced. While similar, the acute onset of functional blindness after trauma fits conversion disorder rather than somatic symptom disorder.
