Abstract Details

Purpose:

to assess perfusion changes of optic disk in patient with unilateral acute nonarteritic ischemic optic neuropathy (NAION) after therapeutic treatment.

Setting:

Federal State Institution "EYE MICROSURGERY” COMPLEX S.N. FEDOROV, RUSSIA, MOSCOW

Methods:

A 48-years old man had the acute NAION of the left eye and had therapeutic treatment. The radial peripapillary capillaries (RPC) density using AngioVue™ on spectral-domain optical coherence tomography angiography RTVue-XR™ device with a scanning area of 4,5*4,5 mm² was measured on both eyes. The optic nerve microcirculation was assessed on the first visit and 12 days, 3 weeks, 1 and 3 months after the treatment.

Results:

The best corrected visual acuity of the left eye after the treatment increase from 0,2 to 1,0. The RPC density of the peripapillary area of the left eye before the treatment was 24,8%; 12 days, 3 weeks, 1 and 3 months after the treatment was 31,6%, 27,0%, 30,5%, 29,2%. The RPC density of the fellow eye before the treatment was 50,6%; 12 days, 3 weeks, 1 and 3 months after the treatment was 53,9%, 51,9%, 53,7%, 55,0 %.

Conclusions:

Our treatment showed good visual results in the patient with acute NAION of the left eye, but insignificant changes of the microcirculation in comparison with the normal and the fellow eye. Patients with NAION require dynamic observation.
