Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study aims to determine the impact of Meibomian Gland Dysfunction (MGD) dry eye on low contrast black/white (luminance) and cone color sensitivity performance and improvement in these functions after in-house non-invasive Meibomian gland (MG) expression.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study offers possible benefits from gland expression to patients and subjects in terms of clinical measurements and care associated with meibomian gland dysfunction impacting all age ranges. Prior studies show that these interventions improve dry eye symptoms with intent to improve vision, low contrast color, and B/W vision after intervention in this study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

non-invasive Meibomian gland (MG) expression

Baseline testing of visual acuity, contrast sensitivity, color vision, and Innova, Inc. cone and B/W low contrast vision will be measured.

The intervention will be standard clinical expression of Meibomian superior and inferior glands (MG) using a sterile cotton tip applicator to apply gentle pressure in a rolling motion in the direction of the MGs along the upper and lower eyelid margins to allow oil secretion of the tested eye. One drop of sterile saline will be instilled following the intervention to remove debris. The subject's visual acuity, contrast sensitivity, color vision, and Innova, Inc. cone and B/W low contrast vision will be measured before and after this intervention.

Group Type EXPERIMENTAL

Meibomian gland (MG) expression

Intervention Type PROCEDURE

The procedure is performed with a sterile cotton tip applicator once in the upper and lower eyelids of the subject's choosing.
