At this price, there's no reason this large 3-dimensional model isn't available for use by eye cancer (also called uveal melanoma, choroidal melanoma, eye melanoma, ocular melanoma, intraocular melanoma and ciliary body melanoma) patients and their ocular oncology or retinal specialist physician.
The removable eye model is mounted on a sturdy platform allowing full rotation. The outside structure shows the eye muscles and a cut-away view of the three eye layers: the tough, outer layer of the white sclera, the blood-rich middle layer of the choroid and the inner retina, the half-moon area that covers the back of the eye.
For brachytherapy patients, doctors can show their patients exactly where the disc-shaped plaques containing the radioactive seeds will be sewed onto the back of their sclera, what muscles will be cut to access the placement area and what vital structures, such as the optic nerve, could be impacted. Patients receiving proton beam, will see how the narrow beam will enter through the pupil to the target area. The model can also be used to explain other less common but available therapy such as trans-scleral resection or TTT.
The horizontal halves of this model can then be separated for a look inside the eye. With this perspective, patients will appreciate the physical location of the tumor to vital internal structures such as the macula, fovea, major blood vessels, and the optic nerve, and compare that to the location of the external plaque delivering the tumor-killing radiation to the choroidal layer, where more than 85% of eye tumors arise.
Depending on the tumor size, location and dose delivery, some radiation will seep past the choroid and negatively impact the retina causing a condition known as radiation retinopathy.
The iris projects images onto the retina which sends those signals through the optic nerve to the brain for sight. Radiation retinopathy damages the smooth retinal surface, distorting and interrupting the visual process. Using this model, patients will see just how and why this happens.
This model allows doctors to share with their patients vital insight into their care. And that's a perspective worth seeing.
It’s your sight.
It’s your life.
