Sudden and rapid increase in intraocular pressure

Introduction In acute angle-closure glaucoma, the pain is radiated around the eyelids, sinus, ear roots, teeth, etc. in the area of the trigeminal nerve; the intraocular pressure rises rapidly, the eyeball is hard, often causing nausea, vomiting, sweating, etc.; patients see incandescent lights around A color halo appears or a rainbow like rainbow after rain.

Cause

The cause of sudden and rapid increase in intraocular pressure:

It is caused by sudden narrowing or closing of the angle of the eye, and the aqueous humor cannot be discharged in time, causing the water to rise and the intraocular pressure to rise sharply. More common in middle-aged and older people, 90% of those over 40 years old. The incidence of women is higher, with a male to female ratio of 1:4. Acute angle-closure glaucoma is actually due to the repeated delay of chronic angle-closure glaucoma.

Ophthalmologic eye examination

Examination and diagnosis of sudden and rapid increase in intraocular pressure:

The situation is fierce, the symptoms are mild, the anterior chamber is narrow or completely closed, the sudden onset of intense eye swelling headache, sharp vision loss, eyeball hard as stone, conjunctival hyperemia, nausea and vomiting, constipation, blood pressure, at this time Systemic symptoms are more likely to be misdiagnosed as gastroenteritis, encephalitis, neuropathic headache and other diseases. If you do not get timely diagnosis and treatment for 24-48 hours, you can completely lose sight and have no light. At this time, it is called "violent glaucoma", but some patients in the clinic are less tolerant of pain, only manifested as eyelids and eye discomfort. The eye has no symptoms and is transferred to the forehead, ears, maxillary sinus, teeth and other pain.

Differential diagnosis

Symptoms of sudden and rapid increase in intraocular pressure:

Increased intraocular pressure: the contents of the eye include the lens, vitreous, aqueous humor, and the like. One of the functions of aqueous humor is to maintain intraocular pressure. Normally, the aqueous humor is in a dynamic cycle. If any part of the aqueous circulation channel is obstructed, or if the aqueous humor is excessive, it will cause an increase in intraocular pressure. The normal range of intraocular pressure in humans is between 10 mmHg and 21 mm Hg, and 21 mm Hg to 23 mm Hg is considered to be suspected high intraocular pressure. Abnormally above 24 mm Hg, the performance is as follows: Pain, headache, sometimes nausea, vomiting. Vision is declining. The symptoms of people and people can be different. Therefore, the reason for the diagnosis of high intraocular pressure should be considered in combination with the underlying diseases of the patient itself.

High intraocular pressure: refers to repeated measurements of intraocular pressure above the normal range, but after long-term follow-up, does not cause changes in the optic papilla and visual field.

Eyeball: It means that the eyeball is out of the normal range. The normal eyeball protrusion of Chinese people is 12-14m, with an average of 13mm, and the difference between the two eyes is no more than 2mm. Eyeballs can be signs of eye disease or symptoms of systemic diseases. In addition to the disease itself in the sputum, it is often closely related to diseases of internal medicine, otolaryngology, neurosurgery, and oncology.

Eye movement: Mostly due to congenital hypoplasia, trauma or disease, resulting in abnormal anatomical position of both eyes. Ocular symptoms of sinus cysts: diagnosis of clinical manifestations such as eye pain, diplopia, tearing, and eyeball shift.

The situation is fierce, the symptoms are mild, the anterior chamber is narrow or completely closed, the sudden onset of intense eye swelling headache, sharp vision loss, eyeball hard as stone, conjunctival hyperemia, nausea and vomiting, constipation, blood pressure, at this time Systemic symptoms are more likely to be misdiagnosed as gastroenteritis, encephalitis, neuropathic headache and other diseases. If you do not get timely diagnosis and treatment for 24-48 hours, you can completely lose sight and have no light.
