Retinal Detachments

The main symptom associated with Retinal Detachment is sudden partial or full blindness in the effected eye.

The retina is a thin, light sensitive layer of nerve cells at the back of the eye. Retinas detach because they have one or more holes in them, which allows fluid to pass underneath them. This fluid causes the retina to become separated from the supporting and nourishing tissues underneath it.

Symptoms

The main symptom associated with Retinal Detachment is sudden partial or full blindness in the effected eye. Quite often, a detached retina can be preceded by a sudden increase in floaters, and the appearance of flashes in your vision. However, there are other causes for these symptoms too, so there’s no need to panic if you do experience them. It is important to be checked out by an eye specialist, however, to identify whether a detached retina is the cause or not.

A detached retina does not cause any pain, but you should not delay in seeking medical help, because if left untreated, the loss of vision can often be permanent.

Causes

Retinal detachment usually begins with a retinal tear, or hole in the retina. When a small hole or tear occurs, fluid from the eye can seep into the space between the retina and the back of the eye, which peels the retina away further.

Movement of Vitreous Gel

The vitreous ‘gel’ within the eye tends to shrink with age, and can pull on the retina. In some cases, the vitreous gel can peel the retina away from the back of the eye, resulting in a macular hole or retinal tear. This can progress into a retinal detachment if left untreated.

Injury or Trauma

Very occasionally, an injury to the eye or trauma can result in a retinal detachment.

Treatment

If you encounter any of the symptoms of a detached retina, you should seek immediate medical assistance, preferably at the Sydney Eye Hospital which is located at 8 Macquarie St, Sydney (ph: 02 9382 7111).
