Abstract
OBJECTIVE: We report 3 cases of intraoperative floppy-iris syndrome (IFIS) during cataract surgery in patients without a history of selective α1-blocker use but with a long-term history of antipsychotic drug use. We reviewed previously reported cases of antipsychotic drug-associated IFIS cases. DESIGN: Observational case series. RESULTS: In case 1, bilateral IFIS developed in a 39-year-old man with chronic angle-closure glaucoma. He had used several classes of antipsychotic drugs to treat schizophrenia, including the first-generation antipsychotic drugs haloperidol and chlorpromazine, the dopamine system stabilizer aripiprazole, the dopamine serotonin antagonists olanzapine and quetiapine, and the serotonin dopamine antagonists risperidone and blonanserin for 7 years. In case 2, a 63-year-old woman with schizophrenia had used aripiprazole, quetiapine, and risperidone for more than 10 years. In case 3, a 65-year-old woman with an organic mental disorder had used haloperidol for more than 10 years. At least 5 cases of antipsychotic drug-induced IFIS have been reported in the literature. CONCLUSIONS: Any class of antipsychotic drugs can cause IFIS. Although antipsychotic drug-induced IFIS can be mild, surgeons should be alert to the possibility of IFIS when they treat patients with current and past use of antipsychotic drugs.
