Long-term use of dopamine antagonist therapies may increase the risk of progression from nonexudative to exudative age-related macular degeneration (AMD), according to a study.
The study included 558 eyes from 354 patients diagnosed with nonexudative AMD and followed them for at least 1 year. After controlling for factors such as age, sex, smoking history, hypertension, and use of Age-Related Eye Disease Study (AREDS) or AREDS2 prescription, the study found that patients on dopamine antagonists for at least 3 years had a significantly higher likelihood of developing exudative AMD (P = 0.005).
The researchers concluded that “These findings warrant further investigation of dopamine signaling in conversion to exudative AMD.”
