What are the causes of retinal detachment?
Retinal detachment can be due to the following:
- Advanced diabetes
- Eye injury
- A sagging vitreous
Retinal detachment can occur when vitreous leaks through a retinal hole or tear and collects beneath the retina.
Aging or retinal disorders can cause the retina to turn thin. This contributes to the risk of retinal detachment as it is due to the collapse of the vitreous and builds up under the retina with may create a tear.
Fluid within the vitreous passes through the tear and starts collecting under the retina which peels it from the core tissues.
