Tiny device may help people living with glaucoma.
One day, eye pressure may be instantly monitored through wireless computer implants. For now, a group of researchers has taken the world one giant step closer to this reality by creating a prototype eye-pressure monitor.
A tiny, wireless, low-energy, solar-powered, pressure-sensing computer the size of the tip of a pen can be implanted into the eye and used to closely monitor changes in intraocular eye pressure (IOP). Elevated IOP is a risk factor for glaucoma. The innovative wireless radio transmitter built into the implant doesn't need external tuning and sends the vital eye pressure information to an external hand-held monitoring device. If shown to be promising in laboratory testing, this prototype implant may one day be taken into human clinical trials.
This is an important advance, because IOP increase is common in some forms of glaucoma, and it can cause much of the damage and vision loss connected with this devastating disease. Continual measurements (every 15 minutes) with this implant instead of the less frequent measurements in the doctor's office will allow for better fine-tuning of treatments, thus potentially limiting the eye damage and vision loss.
