To investigate effects of intravitreal triamcinolone injection on macular functions in patients with diabetic macular edema.


Intravitreal triamcinolone (4mg) injection was applied to 18 eyes of 18 subjects (Type II Diabetus Mellitus, mean age 57, M/F:9/9) with diabetic macular edema. All patients were assessed for visual acuity (distant [Snellen] and near [Rosenbaum Vision Screener]), contrast sensitivity (Robin Contrast Sensitivity Test), stereopsis (Titmus test), 5-degree macular threshold (Humphrey Field Analyser) and colour vision (Ishihara charts). Measurments were performed in treated and fellow eyes within 24 hours before and 1 week, 1, 2, 3 months after injection.


Distant visual acuity was found improved only at 1 month (P=0.016) whereas near vision wasn’t changed significantly. Contrast sensitivity improved at 1 month (P=0.04). Macular threshold increased significantly at 1 and 2 months (p=0,008 and p=0.008, respectively).


In patients with diabetic macular edema, intravitreal triamcinolone injection improved distant visual acuity, contrast sensitivity and macular threshold temporarily.
