Objective: To analyze the spectrum and epidemiological characteristics of neuro-ophthalmic diseases from single center, and to provide basis for guiding the diagnosis and treatment of neuro-ophthalmic diseases. Methods: Patients with neuro-ophthalmic diseases admitted to the neuro-ophthalmology ward of Chinese PLA General Hospital from January 1, 2010 to December 31, 2021 were enrolled. The age, gender, regional distribution and disease subtypes of all included patients were retrieved and recorded from the electronic case system. Results: A total of 7245 patients with neuro-ophthalmic diseases were enrolled, including 3331 males(46.0%)and 3914 females(54.0%), with a male to female ratio of 1:1.2. The average age was 38.2±17.5 years. 83.25%(6031/7245)were afferent nervous system diseases, 9.92% (719/7245)were efferent nervous system diseases and orbital diseases, and 6.83%(495/7245)were not classified. The ratio of demyelinating optic neuritis(DON)was the highest(40.17%,2910/7245), followed by nonarteritic anterior ischemic optic neuropathy(NAION)(11.37%,824/7245)and traumatic optic neuropathy(TON) (5.15%,373/7245). The ratio of optic nerve atrophy with unknown causes was 7.85%(569/7245). Characteristics of age distribution, the DON and TON were more common in 18-40 age group(the proportion were 48.63% and 44.24%,respectively), the NAION was common in 41-60 age group(66.14%), and the hereditary optic neuropathy was common in younger 18 age group (48.58%). In 2226 DON patients, the proportion of neuromyelitis optica(NMO)/neuromyelitis optica spectrum disorder(NMOSD)-optic neuritis(ON)was the highest(60.02%)and myelinoligodendrocyte glycoprotein antibody(MOG-IgG)ON was 11.68%, while multiple sclerosis(MS)-ON and chronic recurrent inflammatory optic neuropathy(CRION)were relatively low(1.8% and 2.25%,respectively). In DON patients, the male to female ratio was 1:3.08. In NMO/NMOSD-ON patients, the ratio of male to female was 1:8, and that of MOG-ON was 4:5. In atypical ON, the ratio of male to female was higher than that of female(1.28:1). In DON patients, 81.79% of patients were young and middle-aged, and the proportion of children with MOG-ON(less than 18 years old)was 41.15%.Conclusions: DON and NAION are the two most common diseases of neuro-ophthalmic afferent system.
