[The clinical analysis of optic neuropathy relative to Behcet's disease with clinical manifestation of anterior ischemic optic neuropathy].

ABSTRACT

Objective: To summarize the clinical manifestation, treatment and prognosis of anterior ischemic optic neuropathy(AION) which was the manifestation of optic neuropathy related with Behcet's disease (BD). Methods: Retrospective series of case studies. The clinical data of 6 cases (9 eyes) of AION associated with BD who were hospitalized at the neurology ward of Beijing Tongren Hospital from February to June in 2016 were collected, the clinical characteristics of these patients were summarized, visual acuity were compared by using Wingerchuk visual grade before and after treatment. Results: Among the 6 patients with AION associated with BD, there were 4 males and 2 female, aged 38-60 years. All patients were acute onset, 3 cases had the onset of one eye, 2 cases with the onset of both eyes and 1 case with successively onset of both eyes. Optic nerve was damaged in 6 cases (9 eyes), only 1 case felt pain of eyes, the best corrected visual acuity of 4 eyes were less than 0.1, optic disk edema and linear bleeding around optic disk were oberved in all patients, the lower half visual field defect was the most common damage type (5 eyes), P100 latency of visual evoked potential prolonged in all patients, optic nerve MRI showed abnormal signal of optic nerve involvement in 2 patients. All patients were treated with corticosteroids and followed for 3 months, there was significant improvement in 1 eye of which the vision improved above 3 grade, and improvement in 6 eyes of which vision improved for 1-2 grade, while there has been no change in 2 eyes. Conclusions: BD may be the etiology of AION. Visual impairment of this kind of patients is relatively serious, visual function is expected to improve with early treatment.
