Experts say that retinal tears are one of the most concerning causes of eye floaters. "If the retina tears, it can release pigment or blood into the vitreous that would be seen as a sudden onset ...
Such floaters appear well-defined and usually bear the appearance of a 'crystal worm' or cobweb. Due to their proximity to the retina, the floaters have a significant effect on the visual field for patients. In addition, such floaters are often in the central visual axis as it moves with the intravitreal currents of the eye.
Peripheral (posterior) vitreous detachment occurs when the gel around the eye separates from the retina. This can naturally occur with age. However, if it occurs too rapidly, it can cause photopsia which manifests in flashes and floaters in the vision. Typically, the flashes and floaters go away in a few months.
The vitreous humor is the clear gel that fills the space between the lens and the retina of the eye. A variety of conditions can result in blood leaking into the vitreous humor, which can cause impaired vision, floaters, and photopsia. [2]
Some examples of entoptical effects include: Floaters depiction Purkinje tree depiction. Floaters or muscae volitantes are slowly drifting blobs of varying size, shape, and transparency, which are particularly noticeable when viewing a bright, featureless background (such as the sky) or a point source of diffuse light very close to the eye.
Exudative retinal detachment occurs when fluid accumulates beneath the retina, causing it to detach. [6] [10] [11] This occurs in the absence of retinal tears or breaks. Common causes include age-related macular degeneration, inflammatory diseases, ocular tumors, and injuries to the eye. [6] [9] [10] [11]
