The patient must not have had any treatment for NA-AION prior to our evaluation, There must be a follow-up of 3 months at least to provide enough length of follow-up to obtain valid information in the three treated groups
Exclusion criteria

NA-AION patients with only background diabetic retinopathy will be included, but those who has active neovascularization, vitreous hemorrhages, traction detachment, DME or other complications influencing the visual acuity or fields will be excluded. Patients who had a diagnosis of glaucoma and visual field loss are excluded; however, those with history of elevated intraocular pressure and on ocular hypotensive therapy, with a documented normal field prior to the onset of NA-AION, are included. Patients with a follow-up of less than 3 months are excluded.
