Fluorescein angiography (FA) is a useful test in patients affected by diabetic retinopathy (DR) to evaluate the blood-retinal barrier integrity and the presence of non-perfused areas, vascular leakage, microvascular abnormalities, and neovascularization. The peripheral retina is involved in most DR lesions, and, thus, its proper visualization is crucial for the screening, diagnosis, monitoring, treatment, and prognosis of DR. To expand the field of view, wide-field and ultra-wide-field imaging have been developed, allowing images up to 200° of retinal surface in one single photo. In this chapter, emerging issues concerning ultra-wide-field FA in DR are illustrated.
荧光素血管造影(FA)对于糖尿病视网膜病变(DR)患者是一项有用的检查,可用于评估血视网膜屏障的完整性、无灌注区的存在、血管渗漏、微血管异常以及新生血管形成。大多数DR病变累及周边视网膜,因此,对其进行清晰成像对于DR的筛查、诊断、监测、治疗及预后至关重要。为了扩大视野,已开发出广角和超广角成像技术,能够在一张照片中呈现多达200°的视网膜表面图像。在本章中,将阐述有关DR中超广角FA的新问题。
