PURPOSE:

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

METHODS:

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.

RESULTS:

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).

CONCLUSION:

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