Acute angle-closure glaucoma is a medical emergency that occurs when the fluid pressure inside the eye increases suddenly due to blockage of the drainage channels in the eye. This condition can cause severe eye pain, vision loss, and permanent damage to the optic nerve if not treated promptly.
The term “angle-closure” refers to the angle between the iris (the colored part of the eye) and the cornea (the clear outer layer of the eye). In acute angle-closure glaucoma, the angle between the iris and cornea becomes blocked, which prevents fluid from draining out of the eye, leading to a rapid increase in intraocular pressure.
Symptoms of acute angle-closure glaucoma may include:
- Severe eye pain
- Blurred vision
- Halos around lights
- Nausea and vomiting
- Redness of the eye
- Headache
Diagnosis of acute angle-closure glaucoma typically involves an eye exam, measurement of intraocular pressure, and imaging tests such as ultrasound or optical coherence tomography (OCT).
Treatment of acute angle-closure glaucoma typically involves medications to lower intraocular pressure, such as eye drops or oral medications, and sometimes surgery to remove blockages or create a new drainage channel in the eye. If left untreated, acute angle-closure glaucoma can cause permanent vision loss.
If you experience sudden and severe eye pain or vision changes, seek immediate medical attention, as prompt treatment is crucial for preserving vision and preventing complications.
