Presentation
A P -value Results The demographics of the patients included in this study are presented in Table 1. [dovepress.com]
Method Patients presenting to the eye casualty with symptomatic PVD were examined by the casualty staff. [nature.com]
Retinal tear (defined as a full-thickness break in the retina) is present in about 10% of cases on presentation and a further 2-5% of patients in the weeks that follow). [patient.info]
Signs and symptoms Many patients do not present with acute symptoms when PVD occurs. Presenting symptoms include entoptic phenomena such as floaters, change in pattern of floaters and photopsias. [eyewiki.aao.org]

Entire Body System
- Collapse
[…] v=M0hl-SY_oSQ ) is a normal eye with a C-PVD with collapse. [dovepress.com]
Patients who had complete PVD with collapse of the detached vitreous were most commonly either aged or highly myopic. In fact, this type of PVD was found in over 80% of high myopes. [bjo.bmj.com]
Vitreous detachment is a process in which the vitreous separates from the retina with or without collapsing in on itself. [news-medical.net]
With ageing the vitreous can become liquified and as a result it can pull away or separate from the retina and collapse into the central hollow space of the eye. [myeyespecialist.com.au]
At some point the gel collapses on itself and condenses (the same way a cake falls when brought out of the oven). The posterior portion of the vitreous detaches, or separates, from the retina, yet the more anterior portions remain attached. [retinaeyedoctor.com]
- Weakness
The foveal retina is very thin and can be punched out easily with weak vitreous traction. [dovepress.com]
A reproducibly observed, remarkable finding was a discrete linear signal in the posterior vitreous cavity, characterized by a blue or blue-green weak intensity in the false-color display system of the OCT instrument and distinguished from random noise [jamanetwork.com]
Eyes
- Photopsia
In some patients, there is difficulty in judging which eye is affected by the photopsia. [news-medical.net]
It also may cause photopsia, exacerbated by eye movements. [radiopaedia.org]
Presenting symptoms include entoptic phenomena such as floaters, change in pattern of floaters and photopsias. [eyewiki.aao.org]
As the pockets collapse on themselves, they pull on the retina giving a sensation of flashes of light (photopsias.) Eventually, the vitreous may completely separate from the neurosensory retina. [patient.info]
Common symptoms of retinal tears include: Sudden onset of black spots or ‘floaters’ in your field of vision Photopsia (flashes of light) in one or both eyes Blurred vision Gradually decreased peripheral (side) vision A curtain-like shadow over your visual [austinretina.com]

You should see your optometrist or emergency hospital eye department within 24 hours if you experience any of these symptoms: A sudden increase in the number and size of floaters An increase in the number of flashing lights you see Blurred vision The [specsavers.co.uk]
However, you usually need a further examination if you suddenly develop a lot more flashes or floaters (this could be a small tear) a shutter or curtain of blurred vision drifts across your eye, sometimes from below. [goodhopeeyeclinic.org.uk]
- Vitreous Floaters
“For patients who are totally intolerant of vitreous floaters, vitrectomy may be offered as an option,” he said. [healio.com]
“Floaters” can be seen in the absence of a vitreous detachment and are simply caused from cells or bits of coalesced vitreous casting shadows on the retina. There are, however, other more serious causes of flashes and floaters. [mastereyeassociates.com]
These floaters may represent bleeding inside the eye, torn retinal tissue, or normal aging changes in the vitreous. [eyeconsultants.net]
An operculum can be distinguished from a vitreous floater due to its disc-shaped appearance as compared to the spherical appearance of a vitreous floater. 16 Operculated retinal holes may be symptomatic in the initial stages, but symptoms subside once [reviewofoptometry.com]
Treatment
PVD usually doesn’t require treatment. Complete detachment typically takes no longer than three months. If you continue to see floaters after detachment is complete, discuss treatment options with your doctor. [healthline.com]
Dose and Treatment in Human Donor Eyes T able 1. [iovs.arvojournals.org]
Treatment is only necessary when there is a risk to the health of your retina, in which case you’ll be referred for urgent treatment to repair a retinal tear, hole, or detachment. [specsavers.co.uk]
Laser Treatment for Floaters Recently, a laser procedure called laser vitreolysis has been introduced that is a much safer alternative to vitrectomy for eye floater treatment. [provisu.ch]
Treatment: We will proceed to a retinal periphery examination to control that the vitreous detachment did not tear the retina. [retinegallien.com]
Prognosis
Prognosis The prognosis is generally good for PVD. Boyd K, Vemulakonda GA. Floaters and Flashes. American Academy of Ophthalmology. EyeSmart ® Eye health. https://www.aao.org/eye-health/diseases/floaters-flashes-list. Accessed March 13, 2019. [eyewiki.aao.org]
Treatment and Prognosis In most situations, our board-certified eye surgeons will likely perform a vitrectomy, which removes the vitreous gel substance from the center of the eye to help reduce the appearance of floaters and blurry vision. [houstonretina.com]
[…] like a clear, blue sky Symptoms that may indicate a more serious problem Sudden decrease of vision along with flashes and vitreous floaters Veil or curtain that obstructs part or all of the vision Sudden increase in the number of floaters Treatment and Prognosis [mastereyeassociates.com]
Treatment and prognosis PVD is non-sight-threatening and the symptoms subside in the vast majority of patients. Most patients no longer notice flashes after 3 months and floaters tend to improve. No specific treatment is needed for PVD. [asrs.org]
Prognosis [ 5 ] Most patients become symptom-free over a few months and learn to tolerate the floaters quite quickly. The vitreous will not reattach but the associated symptoms subside and there are no complications. [patient.info]
Etiology
Etiologies include age-related degeneration of the vitreous tissue, elongation of the ocular bulb, and eye injuries. Patients are usually asymptomatic, but may complain of floaters and photopsia. [amboss.com]
In cases of dense VH, ultrasonography (B-scan) may aid in ascertaining the presence of retinal detachment, retinal tear, or any other associated etiologies. [reviewofoptometry.com]
Epidemiology
Epidemiology Prevalence of PVD increases with age and with axial length of the eye. PVD affects most eyes by the eighth decade of life. Age at onset is generally in sixth to seventh decade and men and women appear to be equally affected. [eyewiki.aao.org]
Epidemiology PVD is the most common cause of flashes and floaters. Some older studies suggest a prevalence in high myopes of over 70% by age 65 [ 1 ]. [patient.info]

Pathophysiology
Pathophysiology The vitreous is strongly attached to the retina at the vitreous base, a ring shaped area encircling the ora serrata (2mm anterior and 4mm posterior to it). [eyewiki.aao.org]
The pathophysiologic mechanism of the development of PVD is beyond the scope of this study. However, some aspects warrant discussion. [jamanetwork.com]
Prevention
Source : Patient Prevention It is recommended to drink enough to prevent dehydration of the vitreous. Diagnosis The only way to diagnose the cause of the problem is by a comprehensive dilated eye examination. [provisu.ch]
A dilated exam is recommended to look for possible holes or tears in the retina, and if these are uncovered, prompt treatment can prevent vision loss. Daniel D. Esmaili, MD Retina Vitreous Associates Medical Group [discoveryeye.org]
If a retinal tear is found, it is usually treated with laser to prevent a retinal detachment developing. Laser is usually able to be performed in the consulting rooms. [retinaandeye.com.au]
There is no cure for floaters unless they are disabling or prevent normal day to day functioning, and only then would removal of the gel within the eye be recommended. [retinahi.com]
If a retinal tear is found for example, it can often to be treated with a laser procedure in office to prevent a retinal detachment. Our doctors will thoroughly explain all treatment options available and answer all questions. [retinaspecialistsofmichigan.com]
