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.

Can glaucoma use steam eye masks?

It is not recommended to use steam eye masks for glaucoma. Because glaucoma, especially during flare-ups, causes conditions like eye congestion and edema, using steam eye masks may exacerbate irritation. Glaucoma is a general term for diseases that cause progressive damage to the optic nerve and ultimately impair vision. Glaucoma is primarily associated with pathologically elevated intraocular pressure. It is the second leading cause of blindness globally, and the vision impairment and visual field defects it causes are irreversible. Glaucoma can be classified into primary glaucoma, secondary glaucoma, and developmental glaucoma. Many glaucoma patients do not show obvious symptoms in the early stages and only seek medical attention during acute attacks. Common symptoms during acute episodes include eye swelling and pain, blurred vision, and even headache, nausea, vomiting, and eyebrow pain. If symptoms of glaucoma appear, it is crucial to visit an ophthalmologist promptly to receive treatment to lower intraocular pressure and protect vision.

What are the symptoms of glaucoma precursor?

The prodromal phase of glaucoma is characterized by transient or recurrent attacks, often occurring multiple times, typically in the evenings. During an attack, patients suddenly experience blurred vision and halos around lights, possibly accompanied by pain in the forehead on the affected side or a sour swelling at the root of the nose on the same side. These symptoms are short-lived and can resolve or disappear after rest. If examined immediately, increased intraocular pressure can be detected, often above 40 mmHg, with slight conjunctival congestion or no congestion. There is mild foggy edema in the corneal epithelium. The anterior chamber is extremely shallow, but the aqueous humor is clear, with a wide closure of the chamber angle, slightly dilated pupils, and sluggish light reflexes. After a minor attack subsides, aside from the characteristic shallow anterior chamber, there generally is no permanent tissue damage.

Glaucoma open angle vs closed angle differences

Primary glaucoma is clinically divided into two major categories: angle-closure glaucoma and open-angle glaucoma. The difference between them is that angle-closure glaucoma is due to a pre-existing abnormal configuration of the iris, leading to a mechanical blockage of the anterior chamber angle by peripheral iris tissue, which obstructs the outflow of aqueous humor, thus causing an increase in intraocular pressure. In contrast, open-angle glaucoma has a normal appearance of the anterior chamber angle, which remains open, and its increase in intraocular pressure is due to a pathology in the trabecular meshwork’s aqueous humor outflow system, increasing the resistance to aqueous outflow. Currently, the ratio of primary angle-closure glaucoma to primary open-angle glaucoma is about 3:1, making it the most common type of glaucoma in China.

The difference between open-angle and closed-angle glaucoma

Primary angle-closure glaucoma is a type of glaucoma caused by the peripheral iris blocking the trabecular meshwork, or permanently adhering to the trabecular meshwork, obstructing the outflow of aqueous humor, leading to increased intraocular pressure. It is characterized by a narrow angle and the anatomical feature of the peripheral iris being prone to contact with the trabecular meshwork. Gonioscopy confirming angle closure is an important diagnostic criterion. The characteristic of open-angle glaucoma, however, is that even though intraocular pressure is elevated, the angle remains open, with the obstruction of aqueous outflow occurring at the trabecular meshwork system.

Glaucoma Precautions

Once glaucoma is confirmed, active treatment is necessary, such as medication or surgery. In daily life, the following points should be noted: First, do not stay in dark environments for a long time. Second, avoid excessive use of eyes and ensure to rest. Third, try to avoid drinking strong tea or coffee and do not drink a large amount of water at once. Fourth, avoid using drugs that can trigger glaucoma attacks, such as antispasmodics and antidepressants.
