  • Exposure to Nerve Gas

    Symptoms may include: “pinpoint” pupils and blurred vision; difficulty breathing; muscle twitching; excess saliva and other secretions; impaired judgment, seizures and unconsciousness[] Miosis is a very characteristic symptom of nerve agent intoxication. Victims will often report difficulty in seeing (blurred & dimmed vision).[] Immediate signs of sarin exposure include runny nose , watery eyes, constricted (or pinpoint) pupils, blurred vision, excessive sweating, chest tightness, rapid breathing[]

  • Cholinergic Crisis

  • Cholinergic Agent

    According to Advanced Cardiac Life Support (ACLS) protocol (2000), atropine is the drug of choice to treat symptomatic sinus bradycardia.[] Bethanecol can produce side effects such as shortness of breath, blurred vision, and dizziness.[] The pupil also constricts (miosis).[]

  • Carbamate Poisoning

    About 50% of the patients developed sinus tachycardia and only 3 of the subjects had sinus bradycardia.[] Adverse effects of pralidoxime: dizziness, headache, nausea, blurred vision, muscle weakness. Patient Disposition: Admit for observation (for 36-72hrs?)[] Dyspnea and vomiting were the most common symptom and miosis and cyanosis were the most frequently observed signs.[]

  • Pyridostigmine

    This medication may cause blurred vision or impair your thinking or reactions.[] Adverse effects • Muscarinic—Nausea, vomiting, diarrhoea, abdominal cramps, increased peristalsis, increased salivation, increased bronchial secretions, miosis, diaphoresis[] EENT: miosis. GI: abdominal cramps, nausea, vomiting, diarrhea, excessive salivation, increased peristalsis. Musculoskeletal: muscle cramps, muscle fasciculations.[]

  • Anisocoria

Do you have any loss of vision? Do you have eye pain?[] The subgroup with the most pronounced basal miosis of the symptomatic side demonstrated a uniform pattern of deficient symptomatic side dilatation after OH-amphetamine and[]
