New treatments for diabetic macular edema

Figure 1 Mean retinal thickness (A) or visual acuity (B) following intravitreal triamcinolone injections over 7 years. Number of intravitreal triamcinolone injections from a cohort of 92 eyes receiving intravitreal triamcinolone (IVTA) in a given 6-mo period and up to 84 mo (seven years) later. Note that the initial number for n is recorded as 94 in this graph as two eyes from the 92 in the cohort received two injections in the first six month period. There was a significant improvement in macular thickness both between number of IVTA administration and one month later, and also between one month and three months following IVTA administration (P < 0.02, Wilcoxon matched-pairs signed rank tests) and also between one month and three months following IVTA administration (P < 0.04, Wilcoxon matched-pairs signed rank test).
