Weiss ring: a large, ring shaped floater that is sometimes seen if the vitreous body releases from the back of the eye. When this occurs there is a characteristic pattern of symptoms: Flashes of light ; A sudden dramatic increase in the number of floaters; A ring of floaters or hairs just to the temporal side of the central vision
According to Dr. Sastry, "If the source of the floaters is not benign, such as a retinal tear, intraocular bleeding or inflammation, the eye may need to be treated with oral medications, laser ...
When the retina detaches, common symptoms include seeing floaters, flashing lights, a dark shadow in vision, and sudden blurry vision. [1] [3] The most common type of retinal detachment is rhegmatogenous, which occurs when a tear or hole in the retina lets fluid from the center of the eye get behind it, causing the retina to pull away.

Floaters: Tiny particles drifting across the eye. Although often brief and harmless, they may be a sign of retinal detachment. Retinal detachment: Symptoms include floaters, flashes of light across your visual field, or a sensation of a shade or curtain hanging on one side of your visual field.

The two sides of the RPE include the choroid side, where blood vessels form and bring nourishment to the eye, and the photoreceptor side, with rods and cones that receive light signals.) In particular, the RPE secretes vascular endothelial growth factor (VEGF) at its basement membrane, with the VEGF reaching the choriocapillaris to maintain ...
When they are first noticed, the natural reaction is to attempt to look directly at them. However, attempting to shift one's gaze toward them can be difficult because floaters follow the motion of the eye, remaining to the side of the direction of gaze. Floaters are, in fact, visible only because they do not remain perfectly fixed within 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.
