One thing is how malignant glaucoma?

The general view, Malignant primary angle closure glaucoma is a type of glaucoma. This type of glaucoma with ordinary conventional anti - glaucoma drugs or conventional treatment of glaucoma surgery is often ineffective, but will invoke the elevation of intraocular pressure, if handled properly often leads to blindness, because the consequences could be serious and called malignant glaucoma. Apart from malignant glaucoma with anterior chamber angle-closure glaucoma shallow, narrow-angle characteristics, but also with some other anatomical features, short axial length, corneal, lens thickness, these factors caused the water into the vitreous countercurrent, making further anterior chamber shallow, occlusion angle, elevation of intraocular pressure. From the onset mechanism, the anatomy of factors led to this disease is the key, so malignant glaucoma called ciliary Central block glaucoma.
In closed-angle glaucoma, the incidence of malignant glaucoma lower, and more generally in glaucoma filtration surgery after. But it may also be a local point before surgery after miotic agent. If Preoperative IOP difficult to control drug use, more vicious after surgery glaucoma. The disease incidence has eyes tendency eye after a malignant glaucoma, an eye disease of the anterior chamber may be normal, angle can also open, but application point of miotic purposes glaucoma or ocular surgery, may equally vicious glaucoma.
Vicious in the secondary glaucoma can be traumatic, uveitis, ciliary body edema.
Some malignant glaucoma broken out, the vision criminals, but as long as the alert doctors, and understand the incidence of clinical features, once a clear diagnosis, take active rescue measures, the majority of patients can be saved and the eyesight of the eyeball, so malignant glaucoma is not so people fear of ophthalmopathy.
Clinical malignant glaucoma risk factors:
(1) a genetic factors. (2) axial length short, preoperative measurement axis following more than 22 mm. (3) corneal small, shallow anterior chamber, lens relatively larger. (4) application of ultrasound biomicroscopy checks can be found, the ciliary process larger or position advancement. (5) Application drug miotic after more shallow anterior chamber, IOP higher.
After malignant glaucoma surgery Clinical features:
(1) glaucoma filtration surgery, the anterior chamber natural recovery slow. (2) must use medication anterior chamber before resuming. (3) treatment of patients with anterior chamber must resume. (4) When necessary, the patients need to get rid of some lens anterior chamber before resuming. (5) after surgery may need long-term application of mydriasis medicine.
