The retinal detachment causes are holes or tears in the retina, other health conditions, and eye injuries.
What causes retinal detachment?
Some of the common causes of retinal detachments are:
- Holes or tears in the retina,
- Other health conditions
- Eye injuries
Holes or tears in the retina causes retinal detachment
This happens particularly to people with short sightedness and having thin retina. It the retina has holes or tears in it, fluid in the eye can enter underneath the retina and can detach it from the lining of the eye.
Other health conditions that cause retinal detachment
- Advanced diabetes
- Eye inflammation, such as sarcoidosis or cytomegalovirus retinitis
- Shrinkage of the jelly-like vitreous that is filled inside the eye
Eye injuries that cause retinal detachment
- Trauma
- Complications of eye surgery performed for other eye problems
Retinal detachment cannot be caused by heavy lifting or too much of eyestrain.
Posterior vitreous detachment (PVD)
PVD can also know as the vitreous collapse. With ageing, vitreous may shrink or become liquid. PVD usually does not cause any serious eye problems, but it can develop some visual symptoms such as light flashes (when eyes are closed) and floaters.
Most of the retinal tears are causing by PVD, when not treated may lead to retinal detachment. This can eventually affect the entire retina, causing complete vision loss in the affected eye.
