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...

Biomedical Engineering

Background:

Boston keratoprosthesis type 1 is an artificial cornea implant.
A titanium locking c-ring was added in 2004 to prevent device disassembly.
Magnetic resonance imaging (MRI) safety is crucial for patients with ocular implants.

Observation:

A radiologist identified a radio-opaque object during an X-ray of a patient.
The object was confirmed as the titanium locking c-ring of a Boston keratoprosthesis.
The X-ray was performed to assess MRI safety.

Findings:

The titanium locking c-ring is nonmagnetic.
The presence of the titanium locking c-ring does not impede MRI imaging.
Both the titanium locking c-ring and the Boston keratoprosthesis (with titanium or polymethyl methacrylate back plate) are safe for MRI.

Implications:

Patients with Boston keratoprosthesis type 1 can safely undergo MRI scans.
This confirms the safety of specific keratoprosthesis components for advanced imaging.
Ophthalmologists and radiologists can be assured of the MRI compatibility of this device.
