Produced by the elevation of intraocular pressure, due to the sudden obstruction of the drainage system that allows the aqueous humor of the eye to pass into the anterior chamber. The main consequence is that the angle formed by the iris and the cornea at the point of encounter narrows. It is rare, since it barely represents 5% of glaucoma, but it is a clinical picture of medical urgency and must be treated immediately.
Treatment: Includes surgery, laser or medication, depending on the severity of the glaucoma. Eye drops are used in conjunction with medication to achieve IOP reduction. It is painless and occurs when the patient does not use the eye drops, which help control intraocular pressure and prevent permanent damage. In fact, the main cause of glaucoma blindness is due to lack of adherence to medication treatment.
