[Chinese expert consensus on dry eye: dry eye related to drugs (2021)].

Ocular local or systemic medication may cause drug-related dry eye, which has become one of the important types of dry eye. A missed diagnosis or misdiagnosis of this type of dry eye is easy to occur clinically. To arouse the attention of ophthalmologists, experts from the Chinese Branch of the Asian Dry Eye Society and other related academic organizations have combined the new research progress and clinical practice associated with this specific disease, in terms of its definition, classification, risk factors, related drug types, pathogenesis, diagnosis, differential diagnosis, treatment principles and preventive measures, to form expert consensus opinions, hoping to promote the standardized diagnosis and treatment of drug-related dry eye in China.
