Pathologic production and deposition of PEX material has been associated with development of intraocular complications (corneal endotheliopathy, iridopathy with reduced pupillary opening, ciliary body alterations, instability and degenerative changes of zonular apparatus, increased lens mobility, lens or intraocular graft decentration and dislocation, pigment dispersion, secondary open-angle and angle-closure glaucoma
, pseudouveitis, anterior synechiae, and anterior chamber hypoxia).
Results: The definitions and classifications of both primary open-angle glaucoma and primary angle-closure glaucoma
differ between Chinese glaucoma consensuses and international primary glaucoma guidelines.
Conversely angle-closure glaucoma
(ACG) is usually a more acute process with more immediate signs and symptoms, but which also can also share similar properties to open-angle glaucoma.
Suddenly, unexpectedly, she lost her vision in her only seeing eye from an attack of acute angle-closure glaucoma
. With none of her children around, the house help looking after her was helpless and it took more than two weeks before the correct help came.
This accumulation causes intraocular complications including cataract, open-angle glaucoma, angle-closure glaucoma
, lens decentration, and iridopathy.
Open-angle glaucoma and angle-closure glaucoma
represent make up around 80 per cent of all cases.
They also reported different tendencies to complications: the incidence of angle-closure glaucoma
was 69.23% in the nanophthalmos group versus 0% in the posterior microphthalmos group, while the incidence of macular folds was 0% versus 24%, respectively .
Configuration of the drainage angle, intraocular pressure, and optic disc cupping in subjects with chronic angle-closure glaucoma
They discuss trabeculectomy, deep sclerectomy, glaucoma drainage device surgery, postoperative management of filtering procedures, the role of the ocular surface, and modulation of scarring processes in glaucoma surgery; new devices and techniques, including laser-assisted techniques, viscocanalostomy and canaloplasty, and ab interno Schlemm's canal surgery; and surgical approaches to angle-closure glaucoma
, concomitant cataract and glaucoma, pediatric glaucoma, and refractory glaucoma.
While acute angle-closure glaucoma
is the most common painful glaucoma, some forms of secondary open- and closed-angle glaucoma are associated with acute pressure spikes and pain.9
The second most common type is angle-closure glaucoma
, where the angle between the iris and cornea is narrow and doesn't permit adequate fluid drainage, resulting in increased IOP Unlike open-angle glaucoma, angle-closure glaucoma
develops quickly; symptoms include eye pain, blurred vision, nausea and vomiting, and seeing halos around lights.
