Patients with a history of acute glaucoma attacks, treated with medication or surgery, may have a legacy of dilated pupils even if the IOP drops. Recent studies have shown that many of the closed-angle glaucoma in the Chinese population is due to atrial angle drainage disorders caused by the cataract expansion phase, and a significant number of patients have good control of IOP after cataract extraction and IOL implantation. However, some patients have irrecoverable pupillary dilatation. Other patients with ocular trauma may have an enlarged pupil due to loss of function of the pupillary scotomata, even though the iris is not defective. Dilated pupils caused by other conditions are relatively uncommon. A dilated pupil is not a serious problem, but it still causes some discomfort for the patient. They may be afraid to open their eyes in bright light, and they may not be able to see clearly enough, and they may easily suffer from eyestrain. Excessive UV radiation through the pupil to the fundus of the eye can also cause damage to the macula. Only a small percentage of these can be temporarily reduced by drops of pupil-reducing medication. Many patients have to adapt to this condition on their own for a long time. Pupilloplasty: This can be performed interspersed with combined glaucoma cataract surgery or ocular trauma surgery depending on the patient’s specific condition, or it can be performed in stage II after all ocular conditions have stabilized.
