阿托品是一种在临床上应用甚广的经典药物，在眼科方面，阿托品可用于验光前的散瞳以及治疗弱视、虹膜睫状体炎、恶性青光眼等。近年来，阿托品用于近视眼防控这一“老药新用”的现象成为热点，其有效性已得到初步认可，但在广泛推广应用于临床前，阿托品的安全性同样应受到关注。本文回顾了有关阿托品用于近视眼防控的不良反应情况，因瞳孔扩大引起的畏光最为常见，其次是视物模糊、过敏及炎症反应、局部刺激症状，其他报道的不良反应还有停药反弹、干眼、眼压升高、全身反应、光损伤及毒性作用等。其中，一些不良反应仅为理论推测，还有一些长期效应未明确，待进一步研究探索。目前，阿托品防控近视眼作为临床研究性探索应用是有益的，但应重视其安全性与疗效的评估。n （中华眼科杂志，2021，57：299-304）“,”Atropine is a classical drug with a wide use in clinical practice. In ophthalmology, atropine can be used for cycloplegia before optometry, and the treatment of amblyopia, iridocyclitis, malignant glaucoma, etc. In recent years, the “old drugs with new application ” research and application of atropine for myopia prevention and control has become a hotspot and the efficacy of atropine has been preliminarily recognized. However, before the widely used in clinical, the safety of atropine draws attention. Researches concerning side effects of atropine were searched. The most common problem is photophobia due to dilated pupils, followed by poor near visual acuity, allergy and inflammation, local irritation. Other side effects include withdraw rebound, dry eyes, elevation of intraocular pressure, system reactions, photic damage and toxicity. Among them, some side effects are theoretical yet, and the long-term effects of some side reactions are not clear. Further research and exploration is needed to serve clinical evidence. At present, investigational usage for myopia prevention and control in clinical trials of atropine can be beneficial. Safety observation and efficacy evaluation are equally important in the course of application. (n Chin J Ophthalmol, 2021, 57: 299-304)
