Lacrimal gland

Tearlessness is caused by the underdevelopment of the congenital lacrimal gland or by the disorder of the autoimmune system of the acquired body, which destroys the secretion of the lacrimal gland, leading to the situation of crying without tears. Tearless disease is an eye disease that cannot be cured. Patients can only rely on syrup to improve symptoms, or use special moisturizing glasses to avoid water evaporation.
