Retina is located inside of the rear wall of the eyeball and is formed of light-sensitive cells that receive and process the visual information, is sent to the brain.
This layer of cells is firmly attached to the eyeball and retinal detachment occurs when this attachment is destroyed, some parts of the retina that rose or pulled from its normal position.
Some conditions that can lead to a retinal detachment are:
- severe trauma
- glaucoma
- myopia
- previous cataract surgery
- Previous retinal detachment in the other eye
- family history of retinal detachment
- weak areas of the retina
When retinal detachment occurs, symptoms are small spots or threads in the visual field, usually perceived to be moving, or gray curtains or veils, moving across the visual field. Therefore, the detachment results in visual loss.
In small retinal detachment, also referred to as retinal tears, the goal of treatment is to seal the back of the retina at the back wall of the eyeball. This can be achieved through laser surgery and cryotherapy (freezing), the procedures usually prevent progression to retinal detachment.
Treatment for retinal detachment is surgical and there are many procedures for this condition. Some of these methods utilize pneumatic retinopexy (a gas bubble is injected into the vitreous space eye, pushing the retina back into its normal position), followed by laser or cryo-surgery secures and seals the retina in place.
