The clinical manifestation of lens glaucoma spots is a shorter eye axis length, thicker crystal, more anterior relative position, and shallower anterior chamber. The pupillary block increases posterior chamber pressure and the peripheral iris is pushed forward to block the atrial angle, resulting in obstructed atrial aqueous drainage and increased intraocular pressure. The following diseases need to be differentiated: swollen lens cortical granules in the anterior chamber: lens granular glaucoma: history of cataract surgery or lens trauma anterior chamber is deeper, atrial angle remains open during attacks, atrial water flash is obvious? The anterior chamber contains a large number of swollen healthy searching lens cortical granules with a small number of larger macrophages and small leukocytes, visible in the iris peripheral anterior adhesions. Iron deposits in the lens: iron is the most common intraocular foreign body, foreign body in the lens can form a limited cataract, if the iron foreign body is small, it can exist in the crystal for many years without obvious reaction, iron can oxidize in the eye and gradually spread in the eye, forming ocular rust deposits, including rust deposits in the cornea, iris, lens, and retina, eventually leading to blindness, the rust deposits in the eye with the intraocular foreign body The size and location of the intraocular foreign body are related to the size and location of the foreign body, the larger and posterior part of the eye tend to migrate to the posterior segment of the eye. In the initial stage, there are small brownish-yellow dots under the anterior capsule of the crystal, and in the later stage, there are brown rust spots under the anterior capsule, which can be detected only after the pupil is dilated in the initial stage, and in the later stage, the crystal fibers become degenerated and gradually develop into total cataract, and eventually the crystal is curled up, or the crystal is dislocated due to degeneration of the suspensory ligament. Even if the cataract is removed, vision cannot be restored quickly. Lens rust deposition is a clinical symptom of traumatic cataract. Direct or indirect mechanical damage to the lens can cause cloudy changes, called traumatic cataract. Patients are most often seen in children, young adult males and warriors. There are three common types of cataracts caused by blunt contusions, blast injuries, and penetrating eye injuries. The disease has a variety of names due to the factors causing the injury and the local presentation. Most cases can be described with an obvious history of trauma, however it is important not to overlook traumatic cataracts that deny a history of trauma, especially in infants and children.
