BACKGROUND AND OBJECTIVE
To report on details of the choroid in dry age-related macular degeneration imaged with Swept Source Optical Coherence Tomography.
MATERIAL AND METHODS
Swept Source Optical Coherence Tomography was performed in 28 eyes with dry age-related macular degeneration (Group 1), who were age and refractive error-matched with 28 eyes of 28 healthy controls (Group 2). The visibility and contour of the outer choroidoscleral boundary and suprachoroidal layer was estimated.
RESULTS
Choroidoscleral boundary was visible in all eyes, irregular in 78% in Group 1 and in 18% in Group 2. Suprachoroidal layer was visible in 36% eyes in Group 1 and in 7% eyes in Group 2. Mean choroidal thickness did not differ between groups (p=.11).
CONCLUSIONS
The outer choroidoscleral boundary is irregular in most cases of age-related macular degeneration. Suprachoroidal layer and suprachoroidal space are more often visible in dry age-related macular degeneration than in healthy controls.
背景与目的
报告经扫频源光学相干断层扫描成像的干性年龄相关性黄斑变性患者脉络膜的详细情况。
材料与方法
对28例干性年龄相关性黄斑变性患者的28只眼（第1组）进行扫频源光学相干断层扫描，这些患者在年龄和屈光不正方面与28名健康对照者的28只眼（第2组）相匹配。评估脉络膜巩膜外边界和脉络膜上腔的可视性及轮廓。
结果
所有眼中均可见脉络膜巩膜边界，第1组中78%的眼边界不规则，第2组中18%的眼边界不规则。第1组中36%的眼可见脉络膜上腔，第2组中7%的眼可见脉络膜上腔。两组间平均脉络膜厚度无差异（p = 0.11）。
结论
在大多数年龄相关性黄斑变性病例中，脉络膜巩膜外边界不规则。与健康对照者相比，干性年龄相关性黄斑变性患者中脉络膜上腔和脉络膜上间隙更常可见。
