Glaucoma

Introduction Severe acute angle-closure glaucoma can cause lens changes, and translucent porcelain white or milky white opaque spots can be seen under the anterior capsule of the lens in the pupil area, which is described as glaucoma. The disease belongs to a type of glaucoma caused by the acute closure of the angle of the sensitive person due to certain physical and mental and environmental factors, which leads to an increase in intraocular pressure. Therefore, psychological adjustment is very important in prevention.

Cause

Severe acute angle-closure glaucoma can cause lens changes. Translucent porcelain white or milky white opaque spots, called glaucoma spots, can be seen under the anterior capsule of the lens in the pupil area.

In the early stage of the disease, it can be expressed as a large piece. As the intraocular pressure drops, the flaky turbidity can be partially re-transparent, and the result is punctate, flocculent or hemispherical. A typical change is an oblong or point turbidity at the end of the lens fiber. It tends to be distributed along the lens fiber slits and is therefore often radial. Some of the lesions are lighter, and only a few scattered small spots appear in an irregular arrangement. The occurrence of glaucoma is considered to be the result of nutritional disorders caused by high intraocular pressure. As the age increases, glaucoma can be pushed deep into the transparent cortex. These speckle opacity does not occur in the posterior cortex of the lens and in front of the lens covered by the iris. Glaucoma spots have a certain value in the diagnosis of acute angle-closure glaucoma, especially retrospective diagnosis.

Differential diagnosis

Digestive tract disease

As acute angle-closure glaucoma can cause severe headache and gastrointestinal symptoms during an acute attack, it may be misdiagnosed as a medical or other medical condition and may delay treatment. In order to avoid this, it is very important for non-ophthalmologists to master the basics of acute angle-closure glaucoma.

2. Secondary glaucoma

In addition to acute angle-closure glaucoma, blood-stained glaucoma, lens expansion, lens solubility, glaucoma caused by subluxation of the lens, neovascular glaucoma, secondary glaucoma caused by uveitis can cause acute elevation of intraocular pressure Even left the signs of ocular damage caused by high intraocular pressure, in order to identify the above situation, the most important of which is to check the contralateral eye. For primary angle-closure glaucoma, both eyes often have the same anatomy. Characteristics, if it is found that the contralateral eye does not have the same characteristics, it should be further examined to make a differential diagnosis.

3. Acute iridocyclitis and acute conjunctivitis

The differential diagnosis has been introduced in general textbooks, which is relatively easy, but it must be emphasized that there are contradictions in the treatment of these three diseases. Therefore, a wrong diagnosis will lead to a worsening of the condition and even the possibility of blindness.

4. Malignant glaucoma

Because the clinical manifestations and anatomical signs of primary malignant glaucoma and the disease have many similar aspects, it is easy to cause misdiagnosis. In addition, because the treatment principles of the two diseases are different, the misdiagnosis can cause serious losses, so the differential diagnosis of the two is very important. Malignant glaucoma also has a narrow feature of the anterior segment of the eye, but it is often narrower than the anterior segment of the eye, the thickness of the lens is thicker, the axis of the eye is shorter, and the relative position of the lens is higher. The anterior chamber is shallower and the disease is different. The iris appears to be anteriorly consistent with the front of the lens. The most important thing is that the condition deteriorates after treatment with the miotic agent.
