ABSTRACT
Purpose:
To study the long?term microvasculature changes at the macula and the optic disk in eyes with nonarteritic anterior ischemic optic neuropathy (NAION).Methods:
Patients with acute NAION of less than 6 weeks duration were included. Optical coherence tomography angiography (OCTA) of the macula and the optic disk was performed at baseline, 3 and 6 months and compared with the controls.Results:
The mean age of 15 patients was 52.25 (±9.06) years. The whole image superficial peripapillary density (42.49 ± 5.28) was significantly low when compared to that of control eyes (46.36 ± 2.09); similarly, radial peripapillary capillary density (49.35 ± 5.64) was also significantly reduced when compared to controls (53.45 ± 1.96, P < 0.05). These parameters showed significant progressive decrease at 3 and 6 months (P < 0.05). At the macula, both superficial (41.83 ± 3.64) and deep macular vasculature densities (47.30 ± 2.04) were significantly reduced when compared to control eyes (52.15 ± 4.84 and 55.13 ± 1.81, respectively). The vascular density at the macula remained stable at 3? and 6?months period.Conclusion:
The study shows that the microvasculature in case of NAION is significantly reduced both in peripapillary area and in macular area.
