Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Anatomy of the Eyeball

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...

Area of Science:

Ophthalmology
Biomaterials Science

Context:

Anterior segment reconstruction is crucial for patients with aniridia (partial or complete absence of the iris).
Existing prostheses may have limitations in flexibility and adaptability during implantation.

Purpose:

To describe the flexible iris prosthesis by Koch for anterior segment reconstruction.
To detail its design, implantation techniques, and indications for pseudophakic or aphakic eyes.

Summary:

The flexible iris prosthesis features a customizable design with a silicone matrix core and optional tissue layer.
It is implanted in the ciliary sulcus, offering variants with different flexibility and suturing capabilities.
Techniques for partial and full prosthesis implantation, including size calculation and combination with other procedures, are discussed.

Impact:

Provides a valuable, adaptable option for anterior segment reconstruction, improving outcomes in aniridia surgery.
Facilitates complex procedures like silicone oil surgery by preventing endothelial contact.
Enhances the surgical spectrum for restoring ocular aesthetics and function.
