What Is Pseudoexfoliation Glaucoma?

This disease is a systemic disease. Grayish white debris can be seen on the surface of the lens, iris, ciliary epithelium, and trabecular meshwork. The presence of exfoliated substances increases the incidence of glaucoma 6 times. Currently, it is the most common cause of white glaucoma .

Types of

Systemic disease

Lead

White glaucoma

Main signs

Pupil flakes with white patches.

Symptoms: Early asylum is usually asymptomatic. Second, the main signs

1. White patchy debris on the edge of the pupil.

2. The surface of the anterior capsule of the lens is divided into three regions. The exfoliation in the central region is often curled; the middle region is the transparent region; the peripheral region is the cloud-like region.

3. Transillumination defect of iris around pupil.

4. Glaucomatous changes include enlarged cups, visual field defects, and increased intraocular pressure.

5. The above signs are asymmetric in both eyes.

Third, other signs

1. Irregular melanin deposits on the trabecular meshwork, which is more obvious below.

2. Pigments in front of the Schwalbe line can be seen under the anterior angle lens, especially below.

3. Bilateral onset but often asymmetric, poor response to mydriasis (severe cases, is thought to be secondary to pupil atrophy).

4. Incidence increases with age.

1.

1. Medical history with or without high-temperature work history.

2. Slit lamp and measurement of intraocular pressure, dilated pupils to observe the anterior lens capsule, pupils are often difficult to spread.

3. Anterior gonioscopy.

4. Optic nerve assessment.

5. Visual field inspection: It is recommended to apply automatic visual field inspection.

1. Drug treatment is the same as primary open-angle glaucoma.

2. The initial success rate of argon laser trabeculoplasty exfoliative glaucoma is higher than that of primary open-angle glaucoma.

3. Protective filtering surgery may be considered when medication or laser treatment fails.

4. The course of exfoliative glaucoma is not linear. The early course is often relatively benign with intraocular pressure fluctuations. When intraocular pressure is difficult to control, glaucoma progresses rapidly, sometimes causing severe optic nerve damage within months.

Note: Cataract extraction does not eradicate glaucoma. Due to the slack ligament fibers and the face around the anterior capsule of the iris and lens, the surgery is more complicated and the posterior lens capsule is also prone to rupture.
