Current advances in dry eye disease diagnosis and treatment

Dry eye disease (DED) is a disorder of the ocular surface caused due to hyperosmolarity and insufficient production of tears to moisturize the eye, which leads to less lubrication and ocular surface inflammation and results in visual disturbance and discomfort to the eye. Long-time use of computers, laptops, and mobiles causes less blinking, making the eye's mucin layer thinner, leading to tear-film instability and DED. Tens of millions of people are getting affected by DED worldwide. It is also known as Sjogren's syndrome, which impacts the lacrimal gland of the eyes, decreases tear secretion, and causes the development of aqueous tear film in the eyes and meibomian gland dysfunction. Here we have discussed the various diagnosis methods used for identifying DED and also the emerging technologies for the diagnosis of DED. The treatment options are discussed as per the disease's severity, including novel therapies like autologous serum, topical corticosteroids, and anti-inflammatory agents.
