Lens glaucoma spots, severe acute closed-angle glaucoma can cause lens changes, and translucent porcelain or milky white cloudy spots can be seen under the anterior capsule of the lens in the pupil area, called lens glaucoma spots. The clinical manifestations of lens glaucoma spots are a shorter axial length of the eye, a thicker crystal, a more anterior relative position, and a shallower anterior chamber. The pupillary block increases posterior chamber pressure and pushes the peripheral iris forward to block the atrial angle, resulting in obstructed atrial aqueous drainage and increased intraocular pressure. The basic cause of lens glaucoma is related to the anatomy of the anterior segment of the eye, especially the state of the atrial angle, and the acute onset of the disease can be caused by emotional stress, prolonged work in dark environments and close reading, climate change, and seasonal changes. Most of them appear in the evening or late afternoon, and after sleep or sufficient rest, the IOP can return to normal and the symptoms disappear. A small number of people have no symptoms at all. With increasing age, glaucomatous spots can be pushed deeper by the hyaline cortex. These spots are clouded without appearing in the posterior lens cortex and in front of the lens obscured by the iris. Glaucoma spots are valuable in the diagnosis of acute angle-closure glaucoma, especially retrospectively.
