Central Retinal Vein Occlusion in 2 Patients Using Antipsychotic Drugs

Purpose: To report our findings in 2 patients who developed a central retinal vein occlusion (CRVO) and were chronic users of antipsychotic medications. Case Presentation: Case 1 was a 62-year-old woman who had a sudden reduction of vision in her right eye to 20/2,000. Her fundus showed signs of an impending CRVO with marked macular edema. She had been taking antipsychotic drugs (quetiapine fumarate and risperidone) for about 2 years. She refused anti-VEGF therapy for her macular edema but selected systemic kallidinogenase. Two days later, the macular edema was significantly reduced but the number of cotton wool spots (CWS) was increased. Ten days later, the macular edema was resolved and her BCVA improved to 20/60. The CWS gradually disappeared, and her BCVA improved to 20/20. Case 2 was a 43-year-old man who presented with vision reduction in his right eye of 1 week's duration. His BCVA was 20/50 and his fundus showed signs of a CRVO-related macular edema with CWS in the peripapillary area. He had been taking sulpiride (Dogmatyl^TM) for depression for 1 year, and his blood test showed an increase in red blood cells and hematocrit. Anti-VEGF therapy was performed, and the macular edema was resolved with vision improving to 20/20. There has been no recurrence to date in both cases. Conclusions: These results indicate that a CRVO can be a complication of chronic use of antipsychotic medications. However, early treatment can lead to good outcomes. Clinicians should question patients who develop a sudden CRVO whether they are using antipsychotic medications.
