Retinal Microvascular Abnormalities in Neurofibromatosis Type 1 Associated with Congenital Retinal Macrovessels

Retinal microvascular abnormalities overlying choroidal nodules in neurofibromatosis type 1

BACKGROUND Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder involving aberrant proliferation of multiple tissues of neural crest origin. Retinal vascular alterations in NF1 have rarely been reported in the literature and their nature is not clear. This study describes distinctive retinal microvascular alterations and their relationship to choroidal nodules in patients with neuro...

Corkscrew retinal vessels in neurofibromatosis type 1: report of 12 cases.

AIM To describe a distinctive spectrum of retinal microvascular abnormalities in 12 patients with neurofibromatosis type 1 (NF-1). METHODS This is an observational prospective study of the ocular fundus evaluated by direct ophthalmoscopy with or without fluorescein angiography, to investigate retinal microvascular abnormalities in 32 patients with NF-1 and in 30 control subjects. The evaluati...

Optical Coherence Tomography Angiography of Retinal Microvascular Changes Overlying Choroidal Nodules in Neurofibromatosis Type 1

PURPOSE To report 3 cases of neurofibromatosis type 1 (NF1) with choroidal nodules associated with retinal microvascular changes imaged with optical coherence tomography angiography (OCTA). METHODS Small case series in 3 NF1 patients. OCTA examinations were performed by a trained examiner (J.J.) after pupillary dilation. A standard scan, centered over the macula measuring 6 × 6 mm and 3 × 3 m...

Retinal Microvascular Response to Short-Term Exposure to Particulate Matters As an Indicator of Cardiovascular Effects in Work Environments

Introduction: According to the literature, Central Retinal Arteriolar Equivalent (CRAE), Central Retinal Venular Equivalent (CRVE), and Artemio Venule Ratio (AVR) are three important markers in determining the changes of retinal artery. These markers are employed as an indicator of cardiovascular effects in workers. This study aimed to evaluate the changes in retinal micro vascular responses in...
