Glaucoma is a group of diseases characterized by pathological increase in intraocular pressure that causes damage to the optic nerve and visual field defects. The treatment for glaucoma can include conservative management and surgical interventions. The primary goal of treatment is to control intraocular pressure and delay the progression of optic nerve damage. Generally, intraocular pressure can be controlled with medication; if medication fails to control the pressure, surgery may be necessary to manage it.

Can children have glaucoma?

Children can develop glaucoma. Congenital glaucoma typically presents within the first year of life and is more common in boys. The disease onset before the age of two to three years leads to increased eye pressure, which results in the enlargement of the eyeball. This manifests as photophobia, tearing, and eyelid spasms. Once diagnosed, early surgical treatment is recommended. For children under three years old, the preferred surgical procedures are trabeculectomy or goniotomy. As children are in a developmental stage and have poorer overall tolerance, anti-glaucoma medications are only suitable for short-term bridging treatment.

What is glaucoma?

Glaucoma is one of the main blinding eye diseases in ophthalmology, with a certain genetic predisposition, affecting 10 to 15 percent of direct relatives of patients. Intraocular pressure is the pressure exerted by the contents within the eyeball against its inner wall. Glaucoma is a group of diseases characterized by distinctive optic nerve atrophy and visual field defects, and pathologically increased intraocular pressure is one of the main risk factors for glaucoma. The level of increased intraocular pressure and the tolerance of the optic nerve to pressure damage are primarily related to the occurrence and progression of glaucomatous optic nerve atrophy and visual field defects.

Is it serious if glaucoma causes the pupil to enlarge?

Glaucoma is divided into many types, but the most common are primary angle-closure glaucoma and primary open-angle glaucoma. In these patients, if the pupil dilates or enlarges, the angle of the chamber becomes narrower, leading to increased intraocular pressure, which we refer to as an acute attack of glaucoma. After an attack, patients may experience headaches, nausea, and vomiting. Therefore, it is crucial for glaucoma patients to minimize the time spent in dark rooms to prevent pupil dilation and avoid triggering an acute attack of glaucoma.

What happens if glaucoma worsens?

Glaucoma, if left untreated or improperly treated leading to worsening, can result in blindness, which is referred to as absolute glaucoma. In such cases, it becomes impossible to recover vision; in other words, it is irreversible. Therefore, it is crucial to proactively treat glaucoma after its onset by reducing eye pressure to protect vision, adjusting one's mindset, resting adequately, and avoiding close-range activities. The treatment is generally quite successful nowadays. Glaucoma can be classified into acute angle-closure glaucoma and open-angle glaucoma, both of which are types of primary glaucoma. Additionally, it can be categorized into primary glaucoma, secondary glaucoma, congenital glaucoma, and mixed glaucoma. With active treatment, the outcomes for glaucoma are generally good.

Can glaucoma be contagious?

Glaucoma is not contagious. It is not an infectious disease; rather, it is a group of diseases characterized by increased eye pressure, leading to optic nerve atrophy and vision decline. The most common cause is genetic factors, meaning if elders or parents in the family have this condition, the incidence of glaucoma in their offspring will also be higher. It is an eye disease caused by anatomical abnormalities of the eye. Additionally, some cases of glaucoma are caused by trauma or other reasons, so glaucoma is not contagious.
