A case report of convergence insufficiency related to the use of methyldopa is presented. Methyldopa is a systemic antihypertensive agent. It has sympatholytic properties which lower blood pressure by decreasing peripheral vascular resistance. The proposed effects of methyldopa on binocular vision are reduced accommodative convergence and increased demand on fusional convergence. These effects would create a susceptibility to convergence insufficiency. To my knowledge, an association between methyldopa and convergence insufficiency has not been previously reported.
本文报告了一例与使用甲基多巴相关的集合不足病例。甲基多巴是一种全身性抗高血压药物。它具有交感神经阻滞特性，通过降低外周血管阻力来降低血压。甲基多巴对双眼视觉的推测作用是调节性集合减少和融合性集合需求增加。这些作用会导致易患集合不足。据我所知，甲基多巴与集合不足之间的关联此前尚未见报道。
