AIM: To analyze the characteristics of neurological ophthalmology manifestation of patients with neurosyphilis.<p>METHODS: Retrospective and nonrandomized case analysis were used. Totally 22 cases of 39 eyes were included. They were 17 males and 5 females, aged from 34 to 65 years old. The average age were 49.6 years old. <p>RESULTS: The optic nerve atrophy presented in 11 cases of 22 eyes. One eye of them accompanied by left eye oculomotor nerve palsy; 5 eyes in 3 cases expressed as optic neuritis acute phase; neuroretinitis appeared in 4 cases of 6 eyes; 1 case of 2 eyes expressed as chorioretinitis accompanied by optic disc edema; central retinal artery occlusion were found in 1 case of 1 eye. Argyll-Robertson pupil was as only manifestation in 2 cases of 3 eyes. In all cases, Argyll-Robertson pupil signs can be seen in 19 eyes. Treponema pallidum particle agglutination test(TPPA)were positive in all 22 cases. Syphilis rapid plasma reactin test(RPR)were positive in 19 of 21 cases. All patients underwent lumbar puncture and cerebrospinal fluid were detected for RPR, cerebrospinal fluid protein, white blood cell count. Cerebrospinal fluid RPR were positive in 13 cases. Cerebrospinal fluid protein were greater than 450mg/L in 18 cases. Cerebrospinal fluid white blood cell count were greater than 5/mm³ in 13 cases. <p>CONCLUSION: Neurosyphilis involving neuro-ophthalmology often occurs in middle-aged men and subacute onset. Both eyes can suffered from optic nerve disease simultaneously or sequencely. A few can be expressed as other cranial nerve palsy, which may lead to misdiagnosis. Considering medical history, clinical manifestations, ophthalmic examination, serum and cerebrospinal fluid laboratory tests can improve the diagnostic rate.
