Temporal distribution of post-cataract surgery anterior ischemic optic neuropathy (pcsAION)

A. Temporal distribution of cases of pcsAION in the year following cataract surgery

B. Temporal distribution of cases of pcsAION occurring any time following cataract surgery depicting clustering of cases in the first 9 months following cataract surgery

C. Incidence rate of pcsAION and spontaneous anterior ischemic optic neuropathy(sAION). The incidence rate of pcsAION within 2 months was 8.6 per 100,000 per year (95% CI 2.2–34.5 per 100,000 per year), compared to incidence rate of sAION, which 6.9 per 100,000 per year (95% CI 5.7–8.4 per 100,000 per year), that did not reach statistical significance, with a difference of 1.7 (95% CI −10.3-13.7). The incidence rate of pcsAION within 1 year was 38.9 per 100,000 per year (95% CI 20.2–74.7 per 100,000 per year), compared to incidence rate of sAION, which was 6.5 per 100,000 per year (95% 95% CI 5.3–7.9 per 100,000 per year), that was statistically significant, with a difference of 32.4 (95% CI 7.0–57.8). The incidence rate of pcsAION occurring anytime following cataract surgery was high (86.3 per 100,000 per year), compared to incidence rate of sAION, which was 5.6 per 100,000 per year, that was statistically significant (p<0.001).
