Composite fibrous glaucoma drainage implant

IOP Conference Series: Materials Science and Engineering, 2017
Glaucoma is a frequent reason of loss vision. It is usually caused by increased intraocular pressure leading to damage of optic nerve head. This work deals with the development of fibrous structure suitable for glaucoma drainage implants (GDI). Commercially produced metallic glaucoma implants are very effective in lowering intraocular pressure. However,

Aniridia‐associated keratopathy: Clinical and molecular mechanisms of disease progression and emerging therapeutic targets

Acta Ophthalmologica, EarlyView.
Abstract Congenital aniridia is a rare genetic disorder primarily caused by pathogenic variants of the PAX6 gene. It leads to various panocular anomalies, including aniridia‐associated keratopathy (AAK). This review highlights recent insights into its pathogenesis, focusing on clinical staging, microstructural changes in the cornea and molecular ...

Disadvantages of drainage device for output of intraocular fluid in glaucoma [PDF]

, 2019
Основною причиною ураження очного нерва при глаукомі є підвищений рівень внутрішньоочного тиску (ВОТ), що виникає через втрату функцій трабекулярної мережі ока, через яку виводиться внутрішньоочна рідина [1]. Послідовність лікування глаукоми залежить від
