Mydriasis itself will not cause adverse effects on patients. However, after mydriasis, there may be temporary fear of light and blurred vision (it doesn't matter if you look far away, you can still live normally). The time to return to normal varies according to different mydriatic drugs. Tropicamide usually returns to normal in 4-6 hours, and atropine takes 3 days. Atropine can recover itself after about 2-3 weeks of mydriasis, which is harmless to the eyes. After mydriasis, the eyes can have a rest and can also be used to prevent myopia. However, attention should be paid to shielding under strong light to reduce the intake of ultraviolet rays.
Attention should be paid after mydriasis
(1) The eye ointment applied to the skin outside the eyes should be wiped clean. (2) Atropine can dilate pupils, so it is normal for patients to feel photophobia and difficulty in seeing. (3) Avoid strong light stimulation, especially strong sunlight stimulation, and wear sun hats or sunglasses outdoors. (4) During mydriasis, children should be cared for to avoid collision due to blurred vision. (5) Because mydriasis is to relax the adjustment of ciliary muscles, don't use your eyes at close range during mydriasis, such as reading, watching TV and using a computer. (6) A very small number of children have obvious symptoms such as facial flushing, thirst, fever, headache, nausea, vomiting, constipation, hallucination, spasm, excitement and eyelid edema after mydriasis. If atropine is considered as an adverse reaction, they should stop taking drugs immediately or consult an ophthalmologist. (7) After stopping mydriasis, it takes about three weeks for the pupil to return to normal. However, due to individual differences, the recovery time of pupils will be different, which is normal.
