Abstract:AIM: To study the peripheral blood T-lymphocyte and natural kill(NK)cell in patients with nonarteritic anterior ischemic optic neuropathy(NAION).
METHODS: The changes of CD3+,CD4+,CD8+,CD4+/CD8+, NK in 30 NAION and 31 normal controls were measured by flow cytometry monoclonal immunofluorescence.
RESULTS: CD3+, CD4+/CD8+ ratio in NAION patients had no significant difference from normal control, CD4+, CD8+ decreased significantly.
CONCLUSION: Serious immunological disturbances of T lymphocyte subsets exist in NAION patients.
