概括
在手术前的OCT上,foveal山峰标志可以预测在玻璃切除术后对亚黄斑出血的黄斑孔的形成. 这一发现有助于评估患有视网膜动脉宏动脉瘤破裂的患者的风险.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜疾病 视网膜疾病
- 外科手术的结果
背景情况:
- 从破裂的视网膜动脉大动脉瘤 (RAM) 引起的黄斑下出血 (SMH) 可以导致视力丧失.
- 黄斑孔 (MH) 形成是SMH玻璃切除术后的一个潜在并发症.
- 确定MH的预测因素对于手术规划和患者咨询至关重要.
研究的目的:
- 为了确定与黄斑洞 (MH) 发育相关的术前临床和成像特征,在玻璃切除术后为SMH继发于破裂的视网膜动脉宏动脉瘤 (RAM).
主要方法:
- 对48只因RAM而出现SMH的眼睛进行了回顾性分析,这些眼睛接受了玻璃切除术.
- 对手术前的因素和成像检测结果的比较,其中的眼睛发展了MH,而不是那些眼睛.
- 评价最佳校正的视敏度和光学连贯性断层扫描 (OCT) 发现.
主要成果:
- 黄斑孔 (MH) 在8只眼睛 (16.3%) 形成了视切除术后.
- 在所有MH病例中,手术前的OCT揭示了明显的"叶山峰"标志 (在叶处的最大视网膜厚度与亚内部限制膜出血).
- 与没有 (47.5%,P=0.006) 相比,发病的眼睛 (100%) 的眼睛中,状山峰标志显著更为普遍.
结论:
- 在外科手术前的OCT上的"山峰"标志可能作为一个有价值的指标,表明在与RAM相关的SMH的玻璃切除术后,MH形成的风险增加.
- 这种成像发现可以帮助眼科医生进行风险分层和患者管理.

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
