Patients with acute glaucoma typically present with a sudden onset of symptoms. These may include severe eye pain, headache, nausea, vomiting, blurred vision, and seeing halos around lights. The affected eye may appear red, and the pupil may be mid-dilated and non-reactive to light. These symptoms are due to the rapid increase in eye pressure, which can cause significant discomfort and visual disturbances.

The workup for acute glaucoma involves a thorough eye examination by an ophthalmologist. Key diagnostic tests include:

• Tonometry: Measures the intraocular pressure. Elevated IOP is a hallmark of acute glaucoma.
• Gonioscopy: Assesses the angle between the iris and cornea to determine if it is closed.
• Slit-lamp examination: Evaluates the anterior segment of the eye for signs of angle closure.
• Optic nerve assessment: Checks for any damage to the optic nerve.

These tests help confirm the diagnosis and differentiate acute glaucoma from other types of eye conditions.

Immediate treatment is crucial to lower the intraocular pressure and prevent optic nerve damage. Initial management may include:

• Medications: Eye drops and oral medications to reduce eye pressure.
• Laser therapy: Laser peripheral iridotomy creates a small hole in the iris to improve fluid drainage.
• Surgery: In some cases, surgical intervention may be necessary to create a new drainage pathway.

The choice of treatment depends on the severity of the condition and the patient's overall health.

With prompt treatment, the prognosis for acute glaucoma can be favorable, and vision can be preserved. However, delayed treatment can lead to permanent vision loss. Regular follow-up with an eye specialist is essential to monitor eye health and prevent future episodes.

Acute glaucoma occurs when the drainage angle of the eye becomes blocked, preventing the aqueous humor (fluid) from exiting the eye. This blockage can be due to anatomical factors, such as a narrow angle between the iris and cornea, or other conditions that push the iris forward. Risk factors include age, family history, hyperopia (farsightedness), and certain medications.

Acute glaucoma is less common than other forms of glaucoma, such as open-angle glaucoma. It is more prevalent in older adults, particularly those of Asian descent. Women are also at a higher risk due to anatomical differences in eye structure. The condition can occur in both eyes, but often presents in one eye first.

In acute glaucoma, the normal flow of aqueous humor through the trabecular meshwork is obstructed, leading to increased intraocular pressure. This pressure can damage the optic nerve, which is responsible for transmitting visual information from the eye to the brain. The sudden rise in pressure is what causes the acute symptoms and potential for rapid vision loss.

Preventive measures for acute glaucoma focus on identifying individuals at risk and monitoring their eye health. Regular eye exams, especially for those with risk factors, can help detect narrow angles before they lead to an acute attack. In some cases, prophylactic laser iridotomy may be recommended to prevent angle closure.

Acute glaucoma is a serious eye condition that requires immediate medical attention. It is characterized by a sudden increase in intraocular pressure due to blocked fluid drainage, leading to severe symptoms and potential vision loss. Early diagnosis and treatment are crucial for preserving vision. Understanding the risk factors and maintaining regular eye check-ups can help prevent this condition.

If you experience sudden eye pain, headache, nausea, or changes in vision, it is important to seek medical attention immediately. Acute glaucoma is a medical emergency that can lead to permanent vision loss if not treated promptly. Regular eye exams are essential, especially if you have risk factors such as a family history of glaucoma or are of Asian descent. Your eye doctor can provide guidance on how to protect your eye health and prevent acute glaucoma.
