What are the types of glaucoma?

Many types. Typically the types are divided into "causes" or the "drain status" thus primary glaucoma vs. Secondary glaucoma (caused by something that is affecting the drain of the eye) or open angle vs. Closed angle glaucoma basically glaucoma can happen at various pressures that is damaging to the individual patient, so there is no pressure cutoff.
Many. Many types of glaucoma - classified into primary and secondary types. Specific types include congenital, traumatic, medication induced, inflammatory, angle glaucoma (closed, narrow, or open). Primary open angle glaucoma is common, and more common than we know because it can be generally silent in symptoms, which makes it difficult to detect without routine eye exams.

Any type can, but. Typically a narrow-angle/angle-closure types cause rapid visual loss. This type of glaucoma is symptomatic (eye pain, blurriness, nausea), although by the time the symptoms arise it's often too late. Patients with open-angle glaucoma and low/normal tension glaucoma often experience what *seems* like rapid visual loss, when in reality the 'blind spots' have slowly crept into the central vision.

What type of surgery reduces glaucoma pressure?

Laser, operation. If treatment by anti-glaucoma eyedrops fails or is ineffective, then laser can lower the pressure and for more severe cases there are surgical ways to reduce the pressure including the construction of bypass channels (trabeculectomy) and the implantation of drainage devices. Discuss this with your glaucoma specialist ophthalmologist. Read more...
Several. All eye treatment for glaucoma (eye drops, laser, surgery) reduce intraocular pressure in order to prevent glaucoma damage from worsening. Laser (slt and alt) increases outflow of aqueous humor from the eye into the trabecular meshwork. Trabeculectomy and tube shunts increase outflow of aqueous humor to the outside of the eye by a newly created channel. Read more...
They all do. The purpose of glaucoma surgery is to lower intraocular pressure when medical &/or laser treatment insufficiently does it to protect the optic nerve.
