The safety of atropine for myopia prevention and control

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. (Chin J Ophthalmol, 2021, 57: 299-304).
