Abstract
Purpose :
To estimate the effect of sub-Tenon’s capsule triamcinolone acetonide injection (STTA) combined with panretinal photocoagulation (PRP) using pattern scan laser (PSL) for high risk non-proliferative diabetic retinopathy (NPDR), in terms of the inflammation and the progression of diabetic macular edema (DME).
Methods :
This retrospective study includes NPDR patients underwent PRP using PSL with (STTA+PSL group, n=24) or without pretreatment of STTA (PSL group, n=19). We measured anterior flare intensity (AFI) and central retinal thickness (CRT) at day of STTA (day 0), 1, 3, 7, 11 and 15 weeks.
Results :
The CRT of the STTA+PSL group was significantly lower than that of the PSL group at 7 (p = 0.04), 11 (p = 0.01) and 15 weeks (p = 0.02). AFI levels in the STTA+PSL group were significantly lower than those in the PSL group at 11 (p = 0.007) and 15 weeks (p = 0.009). The significant improvement of CRT from baseline was noticed through the observational periods in STTA+PSL group, but not in the PSL group.
Conclusions :
Pretreatment of STTA has the potential to not only prevent the worsening of DME, but also reduce the CRT and AFI of eyes with NPDR after PRP using PSL.
