Retinal and Vitreous Detachment
Retinal Detachment or Tear
Retinal detachment is the situation when the delicate retina lifts off the inside surface of the eye this can result in immediate loss of sight of the lifted area and if unattended urgently can continue lifting the rest of the retina with irreparable damage. (see simulated image above).
The warning sign is seeing flashes of lights infront of the eyes especially to head movement and a constant shadow appearance in the side vision.
If any of these are noticed you need to see an eyecare practitioner immediately to confirm its cause.
Treatment can consist of laser surgery to spot weld the retina back onto the eye preventing it from further lifting or tearing.
Retinal tear has similar signs, the only difference is that the retina is torn or split.
The end result may be total loss of vision or permanent distorted vision in the affected region.
The vitreous is the clear jelly type fluid that fill the inner part of the eye, it pushes up against the inside of the eye to give the eye its full round shape. If there is a sudden movement or jerk to the head eg an knock of quickly lifting head up from a kneeling position to standing. This sudden move may detach the vitreous off the retina. The immediate awareness is flashes of light and a shadow or film on side of your vision. The normal eventual outcome is that it can settle back but the immediate fear is that it may result in a retinal tear or detachment.
Because the symptoms are similar it is important to seek immediate eyecare.
