1, the management of acute angle-closure glaucoma high intraocular pressure under inflammatory reaction is heavy, should not be complex surgery, should use a variety of drugs combined to lower the intraocular pressure, on the stage, full postbulbar anesthesia, press the eye, reduce the intraocular pressure to about 30mmHg, 29G or 30G needle anterior chamber puncture, inject a little air into the anterior chamber, try to extract the atrial aqueous, if necessary posterior chamber puncture to extract the posterior chamber aqueous, do a small incision of the iris circumferential incision, rapid suturing The incision is made, the eye is massaged to lower the intraocular pressure, the anterior chamber is injected with a little viscoelastic to form the anterior chamber, glucocorticoid anti-inflammatory therapy is given after surgery, the UBM is checked after the IOP is controlled, and trabeculectomy or Phaco+IOL is performed at an elective stage. 2, indications for LPI After the 3-minute dark room excitation test, check the anterior segment OCT before and after the test, there are obvious changes in the atrial angle; check the 24-hour IOP, there is a significant increase in 10pm belongs to the high-risk PACS, LPI is needed, LPI to reduce IOP fluctuations. 3, the problem of malignant glaucoma Nowadays, the occurrence of malignant glaucoma is due to the patient’s ocular anatomical factors – short eye axis, shallow anterior chamber, thick crystal, anterior segment crowding, the first choice of drug treatment such as atropine, ineffective then surgical treatment, limited 25G anterior vitrectomy. 4. True microphthalmia Ocular axis <21mm, equatorial scleral opening + partial full sclerectomy + partial flattened lamellar sclerectomy.
