Atropine eye drops strictly speaking, it just can’t be applied to acute closed angle glaucoma, and like post glaucoma surgery or malignant glaucoma still need to use atropine eye drops, why, atropine is mainly a ciliary muscle paralyzing agent, drops into the eye will make the pupil dilated, like this acute closed angle glaucoma will cause pupillary block, or due to the buildup of iris in the angle of the atrium, causing atrial angle block, which hinders the circulation of atrial fluid, which can cause an acute grand mal glaucoma attack. And like after glaucoma surgery, because the channel for glaucomatous atrial fluid circulation has been opened, the pupil needs to be moved with atropine after surgery to prevent adhesions and to act as an anti-inflammatory. In addition, like malignant glaucoma, due to the surgery or point of use of drugs like pupil shrinking agent, instead of causing glaucoma attacks, so it is called malignant glaucoma, it is not the same mechanism of action, mainly due to the inward entry of atrial fluid into the vitreous cavity, so it is instead the need to use atropine to dilate the pupil, in order to reduce intraocular pressure, so atropine can’t be used for acute closed-angle glaucoma, strictly speaking.
