概括
完整的视网膜色素表皮和外视网膜缩 (cRORA) 和新生的地理缩 (nGA) 是地理缩 (GA) 发展的重要预测因素. 虽然nGA表现出更高的进展率,但cRORA也表明GA风险增加.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜疾病 视网膜疾病
- 生物标志物发现发现
背景情况:
- 与年龄相关的性黄斑变性 (AMD) 需要临床试验的早期生物标志物.
- 地理缩 (GA) 是AMD研究的一个关键终点.
- 目前评估GA进展的方法需要改进.
研究的目的:
- 评估完整的视网膜色素表皮和外视网膜缩 (cRORA) 作为地理缩 (GA) 的早期生物标志物.
- 为了将cRORA的进展风险与新生地理缩 (nGA) 特征进行比较.
- 评估cRORA和nGA在干预试验中的替代终点的有用性.
主要方法:
- 140名双边大德鲁森的参与者被跟踪36个月.
- 光学连贯断层扫描 (OCT) 和彩色底部摄影用于成像.
- 对cRORA,nGA和GA进行了分级,以分析进展率.
主要成果:
- 无论是cRORA还是nGA都与GA发展有显著的关联 (P < 0.001).
- 在24个月内,cRORA对GA的进展概率为26%,nGA为38% (P = 0.039).
- 与cRORA相比,nGA表现出更高的进展风险.
结论:
- cRORA是GA发展的重要风险因素,尽管其进展率低于nGA.
- 特定的nGA特征对于评估GA进展风险至关重要.

01:19Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:14Changes in Skin Color: Clinical Perspectives
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.

01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

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...
