The purpose of this study is an evaluation of a tactile labeling strategy developed in the Ophthalmology Clinical Research Center at University of Texas Medical Branch (UTMB) in collaboration with the UTMB Maker Space to improve low vision patients capability to identify their topical ophthalmic drop treatments and the frequency with which they should be administered. The labeling strategy includes protrusions as frequency markers and shapes to differentiate between treatments of similar frequency prescription.
The first aim is to evaluate the patient capability to identify the number of protrusions and therefore the frequency of administration prescribed. This should be completed in a timeframe that is not frustrating or problematic to the patient in practice.
The second aim is to evaluate the patient ability to differentiate between drugs with similar frequencies based on a shape on the frequency protrusions in a tactile manner. This also should be completed in a timeframe that is not over burdensome or frustrating to the patient. The protocol is designed to evaluate this tactile labeling design in the population it is designed to support.
