What are the causes of vitreous opacities ?
• Blood: diabetes, retinal vein occlusion, trauma, subarachnoid haemorrhage, sickle cell retinopathy.
• Cholesterolosis bulbi, where free-floating, highly refractile crystals are seen in liquified vitreous and in patients with severe intraocular disease.
• Asteroid hyalitis (Benson's disease), where whitish yellow solid bodies, con-taining calcium palmitate and stearate, are suspended in normal vitreous. Prognosis for vision is good.
• Synchysis scintillans: gold or yellowish-white particles made up of cholesterol are located in the vitreous; they settle to the bottom of the eye due to gravity. Associated with previous trauma or surgery to the eye.
• Other, e.g. retinoblastoma, primary amyloidosis.
