Purpose:
|
To present a case of 74 year-old female with poor visual acuity bilaterally as consequence of NAAION atrophy in left and persisting NAAION optic disc edema in right eye.
|
|
Methods:
|
Patient was treated with methyl prednisolone 1g/day i.v. for 3 days and 80 mg perorally decreasig for 10 mg every week.
|
|
Results:
|
hree days after treatment with methyl prednisolone i.v., disc edema on right eye decreased and vision improved
|
|
Conclusion:
|
NAAION is due to ischemia of the optic nerve head, which is primarily supplied by the posterior ciliary artery circulation. Ischemia of axons in NAAION results in axoplasmic flow stasis.The exact mechanism by which steroids act in all these conditions is not known, it seems most probable that they alter capillary permeability and reduce fluid leakage.
