A Laser uses an intense beam of light that can be precisely focused to treat certain diseases of the retina. The retina is the lining in the back of the eye where the images you see are formed.
The main purpose of utilising laser as a treatment is to preserve your current level of vision and prevent further loss of vision from occurring.
There are 3 common types of retinal disease we treat with laser at Australian Eye Care:
- Macular Degeneration: As our eyes age, irregular blood vessels can sometimes grow under the retina in the centre of the line of eye sight. If this occurs then the straight line of vision can be impaired. In some cases laser can be utilised to extinguish the abnormal blood vessels and stabilise your sight to prevent further vision loss.
- Repair a retinal tear or hole: In this treatment laser is proactively used to seal the layers of the retina together. If a tear or hole is not treated, fluid will leak through the tear or hole eventually causing these layers to separate and detach. If this was to happen it may cause vision loss – depending on the degree of detachment.
- Diabetic Eye Disease: Diabetes can cause leakage from small blood vessels causing swelling, which can blur vision if in the centre of the eye, so laser can be utilised to stop the leaking.
Sometimes Diabetes can also cause blood vessels to block and new blood vessels may grow into the eye where they can break and bleed. Laser treatment can be utilised to stop these blood vessels from growing and reducing the risk of vision loss.
