Lens glaucoma spots are one of the symptoms of primary acute angle-closure glaucoma. Severe acute angle-closure glaucoma can cause lens changes, with translucent porcelain or milky white cloudy spots visible under the anterior capsule of the lens in the pupil area, which some describe as glaucoma spots. This disease is a type of glaucoma in which certain physical, mental and environmental factors cause acute closure of the atrial angle in sensitive individuals, leading to an increase in intraocular pressure, so psychological adjustment is important in prevention. The basic cause is related to the anatomy of the anterior segment, especially the state of the atrial angle. Early in the course of the disease, it may appear as a large lamellar pattern, and as the IOP decreases, this lamellar clouding may become partially retransparent, resulting in a punctate, flocculent, or hemispheric pattern. The typical variation is an oblong or punctate clouding, located at the end of the lens fibers. It tends to be distributed along the lens fiber sutures and is therefore often radiolucent. In some milder lesions, only a few scattered dots appear in an irregular arrangement. The occurrence of glaucomatous spots is thought to be the result of dystrophy caused by high intraocular pressure.
