Abstract
Dry eye disease (DED) is a complex disorder of the ocular surface with a loss of tear film homeostasis, causing an imbalance in the tear-air interface and leading to ocular discomfort, pain, and vision issues. Immune control issues are a primary factor in dry eye disorder's origin, progression, and management. The aim of managing DED is to reduce symptoms and improve the life quality of those affected. Despite the diagnosis, up to half of the patients do not get proper care. The scarcity of successful treatments for DED is worrisome, and it is of increasing importance to comprehend the root causes and create more effective therapies to alleviate the distress of those afflicted with the disorder. Therefore, the role of the immune system in the initiation and progression of DED has become the research focus. This paper reviews the current insight into the immune response in DED, the existing treatment methods, and ongoing research to search for better treatments.
