[Chinese expert consensus on diagnosis and treatment of diabetic optic neuropathy (2022)].

Diabetic neuropathy is one of the common chronic complications of type 1 and 2 diabetes, involving the motor, sensory, and autonomic nerves of the central nervous system as well as the peripheral nervous system. When the optic nerve is involved, it is called diabetic optic neuropathy (DON). DON may or may not be associated with diabetic retinopathy. At present, ophthalmologists at home and abroad have insufficient understanding of DON, and early intervention will bring more benefits to the recovery of patients' visual function. Therefore, the Neuro-ophthalmology Group of Ophthalmology Branch of Chinese Medical Association has organized experts to put forward consensus opinions on the diagnosis and treatment of DON, which can help ophthalmologists to better understand and attach great importance to DON, and to do a good job in the screening and prevention of DON, so as to delay the occurrence and development of DON and protect the visual function of diabetes patients.
