Abstract
Purpose:
To evaluate subfoveal choroidal thickness(SFChT) in patients with acute and longstanding branch retinal vein occlusion(BRVO) using enhanced depth imaging optical coherence tomography.
Methods:
Seventy-four eyes of 73 patients with acute and longstanding BRVO were included in this study. These eyes were divided into acute BRVO with macular edema, longstanding BRVO without macular edema. Using enhanced depth imaging from spectralis domain optical coherence tomography (SD-OCT), the central retinal thickness (CRT), SFChT were measured.
Results:
The mean SFChT measured by enhanced depth imaging from spectralis SD-OCT in 49 eyes of 49 patients who was diagnosed with acute BRVO with macular edema was 247.67 ± 70.03 µm, which was no significantly thinner than that in age-adjusted control groups (259.49 ± 52.49 µm; P=0.347). The mean age and central macular thickness of acute BRVO with macular edema group was 61.86 ± 11.05 years and 516.00 ± 146.55 µm. The mean SFChT in 25 eyes of 24 patients who was diagnosed with long standing BRVO without macular edema was 215.32 ± 68.67 µm, which was no significantly thinner than that in age-adjusted control groups (235.20 ± 44.95 µm; P=0.232). The mean age and central macular thickness of longstanding BRVO without macular edema was 68.60 ± 8.29 years and 263.60 ± 69.32 µm.
Conclusions:
SFChT of acute BRVO with macular edema eyes was no significantly thinner than that of age-adjusted control groups and there were same results that SFChT of longstanding BRVO without macular edema eyes was no significantly thinner than that of age-adjusted control groups. BRVO did not affect SFChT.
