Vitreous opacities

Discrete collagen aggregation, liquefaction, hemorrhage, or inflammatory cells forming microscopic intra-vitreal floaters suspended in the eye's vitreous humor that cast shadows on the retina and may degrade retinal image quality. Possible causes are aging, posterior vitreous detachment, vitreous hemorrhage from traumatic/diabetic/hypertensive retinal vessels, uveitis, retinal tear/detachment, and severe myopia causing vitreous detachment.
