Do all glaucoma patients need pupil constriction?

Glaucoma does not always require miotic treatment; pupillary constriction may be necessary during acute attacks. However, for glaucoma patients with stable conditions and well-controlled intraocular pressure, miotic therapy may not be needed. Patients are advised to seek timely medical care and follow their doctor's instructions for treatment. The analysis is as follows:

During an acute attack, the pupil may become moderately dilated or even fixed. In such cases, miotic treatment can help constrict the pupil, reduce iris compression on the anterior chamber angle, improve aqueous humor circulation, and lower intraocular pressure. Under specific circumstances—such as narrow angles, angle adhesions, or elevated intraocular pressure without optic disc damage—doctors may consider using miotic medications to reduce eye pressure and minimize aqueous humor-related damage to the optic nerve.

For patients with stable glaucoma and well-controlled intraocular pressure, miotic treatment is typically unnecessary. Instead, they should continue their current treatment regimen and regularly monitor intraocular pressure and optic nerve status. In open-angle glaucoma, the drainage angle is open, and impaired aqueous outflow is not caused by iris blockage; therefore, miotics are not the first-line treatment. For these patients, doctors may opt for alternative treatments such as laser therapy or surgical intervention to control intraocular pressure and protect the optic nerve.

Patients with colorectal cancer may experience distinctive changes in flatulence, including unusually foul odor, increased frequency, greater volume, presence of blood, or mucus. It is recommended that patients seek prompt medical evaluation and follow medical advice for appropriate treatment. The analysis is as follows:
