Clinical Trial Summary

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.


Description:

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.

Eligibility IInclusion Criteria: Phase I: - Candidates will be healthy adults between 18 and 100 years of age - Candidates will complete the consent briefing and consent documents prior to participating in any study activities. - Phase II:Inclusion Criteria: - Candidates will be between 50 and 100 years of age. - Candidates will have a BCVA equal to or less than 20/70 or have central vision field less than 20 degrees. - Candidates will complete the consent briefing and consent documents prior to participating in any study activities. Exclusion Criteria: Phase I: - Candidates who do not complete the consent briefing and indicate consent through completion of consent documents with or without a witness (as indicated by their ability to read the documents for themselves out loud with whatever optical assistance necessary (large print, magnification, optical correction, etc.), prior to any study activity, will not be included in this study. - History of prior non-compliance or the presence or history of psychiatric condition (including drug or alcohol addiction) that would, in the opinion of the investigator, make it difficult for the subject to comply with the study procedures or follow the investigators instructions.

Advanced neuropathy of the hands, dementia, or mental incapacity) will be excluded. - Candidates who do not complete the consent briefing and indicate consent through completion of consent documents with or without a witness (as indicated by their ability to read the documents for themselves out loud with whatever optical assistance necessary (large print, magnification, optical correction, etc.), prior to any study activity, will not be included in this study. - History of prior non-compliance or the presence or history of psychiatric condition (including drug or alcohol addiction) that would, in the opinion of the investigator, make it difficult for the subject to comply with the study procedures or follow the investigators instructions.

Intervention

Device:
Tactile Labels for Drug identity and dose frequency
The tactile labeling proposed in this protocol is rigid labeling. A ring-clip has an inner diameter of 12.5cm, an outer diameter of 16 cm, and a height of 1.5 cm. The ring is cut at 2 cm to form a semi-circle allowing it to be clipped onto the bottleneck. The ring clip fits most if not all prescription eye drop bottles. The individual protrusions with shapes at the end can be cut off by the pharmacist to match the frequency of administration prescribed.
