Asteroid Hyalosis (AH) - EyeWiki
Asteroid hyalosis (AH) is a common (1 in 200 person) clinical entity in which calcium-lipid complexes are suspended throughout the collagen fibrils of the vitreous. [1] Benson, in 1894, was the first to describe accurately and to differentiate AH from synchysis scintillans.

Mimickers of asteroid hyalosis – (A) montage fundus photography of ocular amyloidosis and (B) Optos imaging of de-hemoglobinzed vitreous hemorrhage resembling AH. Further diagnostic workup is rarely needed for AH or synchysis scintillans but can be pursued in cases where clinical examination and imaging alone are insufficient to differentiate ...
Asteroid Hyalosis - Journal of the Foundations of Ophthalmology
2024年10月28日 · Asteroid hyalosis (AH) is a benign vitreous opacification in which calcium-lipid complexes are suspended throughout the collagen fibrils inside the vitreous cavity (1). These complexes are named asteroid bodies due to their reflective appearance that resemble the stars (asteroids) in the night sky.
Spotlight on Asteroid Hyalosis: A Clinical Perspective - PMC
Asteroid hyalosis is seen as numerous vitreous opacities that are round in shape, bright yellow in appearance, and moves with the vitreous with eye movements but avoids gravitating downwards. Optical coherence tomography show hyperreflective foci in the vitreous (Figure 2).

2023年3月13日 · Figure 3 Mimickers of asteroid hyalosis – (A) montage fundus photography of ocular amyloidosis and (B) Optos imaging of de-hemoglobinzed vitreous hemorrhage resembling AH. Posterior vitreous detachment (PVD) is a far more common entity to consider for older patients presenting with floaters and vitreous debris.
Photocoagulation guided by wide-field fundus autofluorescence …
FA and OCT imaging utilise specific wavelengths of light and are less affected by asteroid hyalosis than are conventional imaging approaches such as colour photography or indirect microscopy, both of which utilise white light. 3, 4 The Optos 200TX (Optos PLC, Dunfermline, UK) used for autofluorescence imaging at our institution utilises green ...

2024年12月5日 · To compare the diagnostic capacity of a color fundus camera (CFC), ultra-wide-field bicolor confocal scanning laser ophthalmoscope (BC-cSLO; OPTOS), and true-color confocal scanning ophthalmoscope (TC-cSO; EIDON) in detecting coexisting retinal diseases in eyes with asteroid hyalosis (AH).
Asteroid Hyalosis: An Update on Prevalence, Risk Factors, …
2023年6月20日 · Today, a growing body of epidemiologic data estimates the global prevalence of asteroid hyalosis to be around 1%, and there is a strong established association between AH and older age. While pathophysiology remains unclear, a variety of systemic and ocular risk factors for AH have recently been suggested in the literature and may provide ...
