Glaucoma is a chronic disease with progressive degeneration of optic nerve fibers resulting in decreased visual field. Elevated intraocular pressure is considered the most important and the only treatable risk factor. This manuscript describes a simple, surgeon-friendly, non-incisional technique, named Ultrasound Cyclo Plasty, for reducing intraocular pressure in glaucoma patients.

A Magnetic Microbead Occlusion Model to Induce Ocular Hypertension-Dependent Glaucoma in Mice

Here, we present a protocol to induce ocular hypertension in the murine eye that results in the loss of retinal ganglion cells as observed in glaucoma. Magnetic microbeads are injected into the anterior chamber and attracted to the iridocorneal angle using a magnet to block the outflow of aqueous humour.

Experimental Glaucoma Induction via Iridocorneal Angle Obstruction In a Mouse Model

In this video, an anesthetized rat undergoes an ocular procedure where magnetic beads are injected into the anterior chamber under a magnetic field to block the iridocorneal angle. This blockage obstructs the trabecular meshwork, preventing aqueous humor drainage and leading to increased intraocular pressure, damaging the retinal ganglion cells and optic nerve. This develops a glaucoma-like condition.

We present a method for inducing elevated intraocular pressure (IOP), by injecting magnetic microspheres into the rat eye, to model glaucoma. This leads to strong pressure rises, and extensive neuronal death. This protocol is easy to perform, does not require repeat injections, and produces stable long-lasting IOP rises.
FAQs
Elevated intraocular pressure is one factor that can make optic nerve fibers more vulnerable to damage. Because this damage may progress before noticeable symptoms appear, day-to-day vision does not reliably show whether risk is changing. Clinicians therefore combine pressure assessment with evaluation of optic nerve structure, supporting earlier recognition of concerning changes and more appropriate follow-up.
Older age, a family history of glaucoma, and certain medical conditions can each increase the likelihood that a person will develop the disease. These factors matter because they help clinicians identify people who may need closer observation, even when symptoms are absent. Risk assessment uses this context alongside intraocular pressure and structural findings rather than treating any single factor as decisive.
Structural changes can indicate that optic nerve fibers may be more vulnerable, adding important information beyond symptoms or pressure measurements. Since optic nerve damage can progress unnoticed, examining these structures helps clinicians judge whether a person requires continued monitoring or consideration of early treatment. Structural assessment is therefore central to identifying risk before irreversible vision loss becomes apparent.
Assessment may include a comprehensive eye examination, intraocular pressure measurement, and evaluation of optic nerve structure. Clinicians also consider age, family history, relevant medical conditions, and other structural changes in the eye. Bringing these findings together helps determine how closely a person should be monitored and whether early treatment may be appropriate.
Risk assessment helps clinicians determine how frequently a person should receive screening and ongoing examinations. Individuals with factors associated with greater vulnerability may need careful monitoring of intraocular pressure and optic nerve structure over time. This planned follow-up can identify concerning changes earlier than symptom-based evaluation and supports decisions about whether treatment should be considered.
Early evaluation is important because glaucoma-related damage may advance before noticeable symptoms develop, while optic nerve loss is irreversible. Comprehensive assessment and continued monitoring give clinicians an opportunity to recognize risk, track pressure and structural findings, and identify people who may benefit from early treatment. This approach can reduce preventable vision loss and support long-term eye health.
