Glaucoma is an eye disease in which the intraocular pressure is either intermittently or continuously elevated. The elevated intraocular pressure can have various symptoms and manifestations depending on its etiology, and the continuous high intraocular pressure can bring damage to various parts of the eye tissues and visual function, causing vision loss, and if not treated in time, vision can be drastically lost or even blindness. Acute angle-closure glaucoma is often preceded by anger, fatigue and other triggers. The acute phase is characterized by severe eye pain, rapid loss of vision, or in severe cases, only the frontal index or light perception, accompanied by ipsilateral headache, often combined with nausea, vomiting, fever, chills and constipation, etc. A few patients may have diarrhea. On examination, high intraocular pressure, dilated pupils, ocular congestion, corneal edema, cloudy atrial fluid, crystal changes, shallow anterior chamber, atrial angle occlusion, and iris atrophy may be found. Since most patients have a combination of elevated blood pressure, headache, nausea, vomiting, fever and chills during an attack, they are often misdiagnosed by primary care doctors as hypertension, cerebrovascular disease, migraine, gastrointestinal disease and the flu, which delays the disease. Once acute angle-closure glaucoma is diagnosed, surgery is the first choice, and drug therapy is only used in preparation for surgery and in cases of poor IOP control after surgery or when surgery is very dangerous. Patients with high intraocular pressure in the acute attack period should be treated with drugs to lower intraocular pressure, preferably 20% mannitol drops, 1% pilocarpine and timothyroxine dots if necessary, or oral acetazolamide. After IOP control, surgical treatment should be chosen, and postoperative IOP control should be supplemented with drugs. With regular and reasonable treatment, glaucoma can control its development rate and preserve the living vision during the lifespan. At present, our ophthalmology department has successfully performed glaucoma surgery on several patients, and the postoperative patients have good IOP control and no further attacks, and the surgical results are satisfactory.
