Perimetric sensitivity with the micro perimeter 1 and retinal thickness in patients with branch retinal vein occlusion.
OBJECTIVE
To evaluate the relationship between retinal sensitivity and thickness of the macular edema associated with branch retinal vein occlusion (BRVO).


METHODS
Prospective case series.


METHODS
We prospectively examined 15 eyes of 15 patients with macular edema associated with BRVO. In each patient, retinal sensitivity in the macular area was examined with the Micro Perimeter 1 (MP-1); retinal thickness was measured by optical coherence tomography (OCT). Eyes with marked retinal hemorrhage or macular nonperfusion were excluded from the current study.


RESULTS
Retinal sensitivity measured with the MP-1 was significantly correlated with retinal thickness in the fovea (R(2) = 0.460) and in all extrafoveal regions (R(2) = 0.383 to 0.794). In four eyes treated with triamcinolone acetonide, retinal sensitivity showed marked improvement in parallel with the reduction of the macular edema.


CONCLUSIONS
Retinal sensitivity in the macular area correlates linearly and negatively with increased retinal thickness in eyes with BRVO.
