Horseshoe or flap tear
The shrinking vitreous can tug on the retina and pull away from it. In about one in six people, a posterior vitreous detachment causes the retina to tear. Fluid from inside the eye can then seep through the tear and separate the retina from the tissues that nourish it. This separation, called retinal detachment, can lead to permanent vision loss. Retinal tears and detachments are painless.
Key warning signs include: This occurs when the macula — the area of the retina responsible for central vision — detaches. The ophthalmologist uses a laser to make a series of tiny burns around the retinal tear. This creates a barrier of scar tissue that stops the tear from getting bigger.
If you experience any of these warning signs, call your doctor right away. You will need to see an ophthalmologist for an eye exam as soon as possible. If a tear is detected early, treatment can prevent the retina from detaching.
Risk Factors Risk factors are: It is often associated with round retinal holes but it can also be associated with flap tears. In fact, there can be a pronounced vitreoretinal adhesion located at the margin of lattice lesions, which can predispose to retinal tears after PVD. These tears typically occur at the posterior margin or posterior lateral margin of lattice degeneration.
Long-term studies suggest that tractional tears are found in 2. General Pathology Horseshoe tears also occur at sites of strong vitreoretinal adhesion, most commonly at the irregular posterior margin of the vitreous base during PVD.
They are more common in the superior temporal quadrant followed by the superior nasal quadrant. U-tears consist of a flap in which its apex is pulled anteriorly by the vitreous while the base remains attached to the retina.
The actual tear consists of two anterior extensions horns running forward from the apex.

Pathophysiology These horseshoe tears occur at sites of strong vitreoretinal adhesion, most commonly at the vitreous base as a result of vitreous traction. Vitreous traction, resulting most frequently from spontaneous vitreous detachment, creates a tear, with the apex of the flap remaining adherent to the posterior vitreous surface.
Because of the persistent associated vitreous traction, flap tears can frequently lead to detachment. When there is persistent traction, the base of the tear can be avulsed leaving a small round defect in the neural retina with an overlying operculum of retinal tissue, aptly named a round hole with operculum.
They generally indicate complete relief of vitreoretinal traction in this area. So very rarely lead to retinal detachment unless vitreoretinal traction persists in the vicinity of the tear.
These breaks are caused by isolated areas of vitreoretinal adhesion and are not contiguous to the vitreous base. They tend to be more posterior than horseshoe tears, and occasionally an operculated round hole is found posterior to a horseshoe tear in the same meridian.How to Get Rid of Eye Floaters
Primary prevention There are no prophylactic measures against the development of retinal tears and PVD. The later is a common phenomenon of the aging eye and in most individuals it will develop without symptoms or pathological sequeale. Nonetheless, this process is also implicated in a large variety of vitreoretinal disorders, namely due to its role in retinal tear formation and subsequent development of most regmatogenous retinal detachments.

Your eye is filled with a clear gel called the vitreous. Changes in this gel cause most eye floaters. You see flashes when the vitreous gel rubs against the retina or pulls on it. This can be easier to see in the dark or when you move your eyes. Many floaters are harmless and your brain eventually gets used to them, but you should have an eye doctor check any new floaters. Seeing flashes of light or getting a new floater or many floaters can be a sign that the vitreous gel is pulling on your retina.
What Are Floaters and Flashes? - American Academy of Ophthalmology
The retina is the tissue at the back of the eye that receives images. A torn or damaged retina can cause vision loss, and this vision loss is sometimes permanent. If vitreous gel goes through a tear in the retina and gets underneath it, this can push the retina out of its normal position on the back of the eye. But even then, doctors cannot always restore all the lost vision.
Call your eye doctor. You should be seen by an eye doctor within 24 hours if you see flashes of light or have a new floater that affects your ability to see.
A complete, dilated eye exam is the only way to make sure you do not have a retinal tear.
