Novel tactile bottle neck adaptor (Ring-IT) facilitates eye drop adherence in visually impaired patients

Researchers tested the use of Ring-IT, a novel 3D tactile bottle neck adaptor in topical eye drop adherence in visually impaired patients. Ring-IT with 1,2 or 3 protrusions with cube or sphere endings were used.  In phase 1, low vision was simulated in 20 healthy subjects with a 20/200 vision simulator; in phase 2, 20 patients with 20/70 or worse vision were recruited. Conclusions: Ring-IT was identified with accuracy and speed by both low vision simulated subjects, and by patients with true limited visual capabilities. These tactile bottle neck ring adaptors can be used as an assistive low vision aid device and may increase eye drop regimen adherence in visually impaired patients.
