Intravitreal Injection Placement Device
A measuring device has been designed to assist physicians in the accurate placement of intravitreal injections to treat wet age-related macular degeneration (AMD). It consists of a lightweight, semi-circular sheath that snaps onto the barrel of a syringe, with a moveable arm that acts as a measurement point when aligned with the limbus (the border between the cornea and the sclera). The design doesn’t interfere with physician visibility or syringe and needle movement.

Safer Macular Degeneration Treatment
AMD is a degenerative disease that causes partial or total vision loss. In the US, AMD among the elderly population is a growing health concern. During a traditional procedure, a physician measures the injection site and marks it with an indentation to the eye surface. The indentation can cause patient discomfort and damage to the eye. It can also disappear prior to injection, forcing the physician to repeat the process, causing further damage and extending the procedure length. Performing the injection without a marked site can be inaccurate and can lead to retinal injury or detachment. The indentation is also difficult to identify on an eye occluded with blood or other abnormalities.
The new device combines measurement and injection into one step, which removes the indentation method, as well as the need to repeat it or to inject without one. This increases patient comfort, increases accuracy, and decreases damage to the eye. The disposable device is made with inexpensive materials, unlike expensive metal calipers which require time-consuming sanitation after use.
