What is PVD (posterior vitreous detachment)
Posterior vitreous detachment is a rare, yet serious condition in which the gel-like substance inside the eye separates from the retina. The retina is your vision’s light sensor, and it can become detached for any number of reasons. Some common causes of posterior vitreous detachments include vision loss due to age, diabetes or high blood pressure, injuries such as a fall or a car accident, side effects from certain medications, and genetic defects.
Due to aging and normal wear and tear, the vitreous gel that fills the eye condenses (shrines) with time. The gel eventually runs out of space in the eye’s vitreous cavity, which positioned at the very back of the eye cavity and stays the same size throughout maturity. As a result, the gel separates from the retina.
Up until the PVD finished and the vitreous gel is solely connected to the retina at the vitreous base, the vitreous gel continues to compress over the next one to three months.
The space between the condensed vitreous gel and the retina filled with clear vitreous fluid.
The actual retinal detachment causes no pain. But before it happens or has progressed, there are usually always warning indicators, such as:
- The unexpected emergence of numerous floaters, which are little specks that seem to be moving through your field of vision
- Luminous bursts in either one or both eyes (photopsia)
- Blurred vision
- Gradually deteriorating peripheral (side) vision
- Your range of vision obscured through a curtain-like shadow.
Why is it important that I get my eyes checked?
The most common cause of abrupt increases in floaters is typically a PVD. A PVD often doesn’t cause any issues. The retina, however, can occasionally tear through the vitreous. A retinal tear may result in retinal detachment and eye haemorrhage. These are major issues that need immediate attention. A thorough dilated eye exam required when a posterior vitreous detachment occurs and new floaters noticed.
How Soon Will My Flashes And Floaters Stop?
The symptoms you initially experienced as a result of the posterior vitreous detachment anticipated to gradually go away.
The floaters, which are actually condensations of the vitreous, do not go away; instead, in most people, they either drift out of sight for a significant portion of the time or people get used to them.
While surgery can used to remove floaters, it is better to put off thinking about it for at least six months, and even then, the hazards usually outweigh any potential advantages. This process could take several weeks or even months.
Importantly, the floaters and flashes you currently see are not harmful as long as they do not worsen or intensify.
In adults under the age of 40, posterior vitreous detachment is uncommon, but as people get older, it becomes more frequent.
Myopia (nearsightedness), trauma, and recent eye surgery, such as a cataract procedure, are additional risk factors for PVD. Within a year, patients who have PVD in one eye are frequently diagnosed with PVD in the second eye as well. For any help, Contact our best eye doctor in west delhi at bharti eye foundation
The floaters or flashes typically go away in three months, but three months following your diagnosis, you should have another dilated eye exam to make sure your retina hasn’t suffered any new harm.
After a few months, if you still have significant floaters, your doctor may suggest using a laser to lessen the floater or having surgery to remove the vitreous gel and remove the floaters.
A retinal tear can fixed using laser surgery or cryopexy, which freezes the tear.
What activities am I still able to undertake despite having PVD?
The majority of patients with PVD unrestricted in their ability to engage in daily activities. High-impact exercise advised avoiding for the first six weeks after the onset of a PVD, according to some ophthalmologists. This is due to the possibility that your vitreous has not fully separated from your retina, and you may be more susceptible to developing a retinal detachment at this time.
Exercises requiring a lot of energy or strong impact, such jogging or aerobicsdoing contact sports, like rugby, boxing, or martial arts.
Inverted poses used in exercises like yoga and pilates.
You can continue doing things like walking, light exercise, reading, watching TV, cooking, and using your computer on a daily basis. There is no evidence to support the idea that taking an aircraft can aggravate or worsen your PVD. Additionally, wearing makeup or contact lenses has no impact on your PVD.
