PURPOSE
Swept Source Optical Coherence Tomography validates lamina cribrosa anomaly in optic disk pit.
METHOD
Observational case report.
RESULTS
A 25-year-old African American male presented with decreased vision in right eye of 4 days duration. Best corrected visual acuity (BCVA) for distance in right eye was 20/200 and in left eye was 20/20. Dilated fundus examination of right eye showed serous macular detachment of entire posterior pole along with an optic pit on temporal margin of optic disk. En-face image of the optic disk on Swept source OCT (SS-OCT) confirmed defect in the lamina cribrosa in the right eye.
CONCLUSION
Congenital optic disk pit a birth defect in lamina cribrosa is a rare, visually impairing disorder. Spectral domain optical coherence tomography (SD-OCT) scan showed neurosensory detachment, however, lamina cribrosa defects are not delineated with it. SS-OCT a recent advance in scanning technology allows superior resolution of optic disk and confirms the anomaly of lamina cribrosa.
目的
扫频光学相干断层扫描技术用于验证视盘凹陷中的筛板异常。
方法
观察性病例报告。
结果
一名25岁非裔美国男性，右眼视力下降4天。右眼最佳矫正视力（BCVA）为20/200，左眼为20/20。右眼散瞳眼底检查显示整个后极部浆液性黄斑脱离，视盘颞侧边缘有一个视盘凹陷。扫频光学相干断层扫描（SS-OCT）的视盘表面图像证实右眼筛板存在缺损。
结论
先天性视盘凹陷是筛板的一种先天性缺陷，是一种罕见的致盲性疾病。光谱域光学相干断层扫描（SD-OCT）扫描显示神经感觉层脱离，然而，它无法清晰显示筛板缺损。SS-OCT作为扫描技术的最新进展，能够提供更高分辨率的视盘图像，并证实筛板异常。
