Key Clinical MessageAluminum phosphide poisoning may cause rare visual impairment. In a case, a 31‐year‐old female, visual loss was linked to shock‐induced hypoperfusion, causing oxygen lack and cerebral atrophy, emphasizing the need for identifying atypical symptoms.AbstractThis case report describes the multidisciplinary evaluation of a 31‐year‐old female patient who suffered from visual impairment as a result of aluminum phosphide (AlP) poisoning. Phosphine, which is formed in the body when AlP reacts with water, cannot cross the blood–brain barrier; therefore, visual impairment seems unlikely to be the direct result of phosphine. To our knowledge, it is the first documented report of such impairment due to AlP.
