Study Overview
Brief Summary
The purpose of this study is to examine the impact of nasal spray treatment on Meibomian gland function and ocular surface health in symptomatic dry eye patients with mild to moderate Meibomian gland dysfunction (MGD).
Detailed Description
Dry eye disease is a common condition that occurs when eyes do not produce enough tears or when the quality of the tears is poor causing tears to evaporate quickly off the eye. This can lead to symptoms such as dryness, burning, irritation, and/or blurred vision. Meibomian gland dysfunction is the most common cause of evaporative dry eye disease. The purpose of this study is to examine the impact of nasal spray treatment on Meibomian gland function and ocular surface health in symptomatic dry eye patients with mild to moderate Meibomian gland dysfunction (MGD). The nasal spray is FDA approved for the treatment of signs and symptoms of dry eye disease.
