Immediate treatment for a retinal detachment should be sought by an eye specialist
A retinal detachment is an uncommon but serious eye condition in which the retina separates from the inner lining within the eye. It is a problem that occurs most frequently in the middle-aged and elderly.
It is more common among near-sighted patients (myopia) and in people who have a family history of retinal detachment. In New Zealand, around 400 cases occur every year. Early symptoms of a detachment may include flashes of light and a sudden appearance of a floater or a 'curtain' or 'shadow' appearing in the peripheral vision.
If you notice these acute types of symptoms you should be seen immediately by an eye specialist. If the 'shadow' does not involve the central part of your vision, retinal detachment surgery should be carried out as soon as possible. If the central vision has already been affected the timing of surgery is less crucial.

A retinal detachment is an uncommon but serious eye condition in which the retina separates from the inner lining within the eye, often associated with holes or tears. It is a problem that occurs most frequently in the middle-aged and elderly.
There are many causes of retinal detachments but most do not have any clear precipitating factor. They are more common among patients with myopia (nearsightedness) and those with a family history of retinal detachment. In New Zealand, around 400 cases occur every year.
The early symptoms of a detachment may include flashes of light and the sudden appearance of floaters. Many people have floaters, which have been present for many years and are not a cause for concern. If a retinal detachment occurs, a visual field defect can usually be noticed as a "curtain" or "shadow" appearing in the peripheral vision and such a symptom should be taken seriously.
Normal eyes
Vision with a curtain or shadow
Patients with retinal detachment symptoms should urgently contact their eye specialist. If the 'shadow' does not involve the central field of vision, retinal detachment repair should be carried out as soon as possible. If the central vision has already been affected the timing of surgery is less crucial.
The surgical principles involve reattaching the retina on the inside of the eye. A laser is used to "spot weld" the retina back on and often a gas bubble is placed inside the eye to help stabilise the retina while it is healing.
If a gas bubble is used the patient's head must be positioned in such a way that the bubble is placed where it can support the healing retina. The gas usually takes about 10 days to reabsorb and air travel is not advisable during this period.
