Definition of Retinal Detachment​



Retinal detachment occurs when fluid accumulates between the retina and the layer underneath it which is called retinal pigment epithelial layer.


The incidence of retinal detachment after cataract surgery will increase in case the patient has:

1- High myopia

2- Intra-operative complications like rupture of the posterior capsule, which will occur after removal of the lens. In this case, the vitreous will come out from the vitreous cavity from the back of the eye to the anterior chamber and it will push the retina forward with it because there are attachments between the vitreous and retina.

3- Collagen Fiber disorders such as Marfan Syndrome, Stickler Syndrome and Ehlers-Danlos syndrome.

The incidence of detachments after cataract surgery can occur in a period that ranges from the first day post operative to weeks or even months.

When there sudden increase in the number of floaters with photopsia or flashes of lights, you should have fundus examination to rule out detachment of the retina. Read more about Eye Floaters.
