Floaters
It is common for people to notice dark spots or strands in their vision from time to time. These can be referred to as floaters. You are more likely to notice floaters as you get older or if you are short sighted. Whilst floaters are generally harmless, it is important to seek urgent advice from your GP or Optometrist if you notice a sudden increase in the number or size of floaters or if you notice these are accompanied with flashes of light or a shadow in your vision. Occasionally, this can be a sign of the back of the eye – known as the retina – detaching. A retinal detachment is a sight threatening condition and as such urgent medical assistance is required if these symptoms are noticed.
What are the floaters?
People with floaters describe black spots or something that looks like a strand of hair or cobweb floating in their vision. What the person is actually seeing is tiny clumps of gel or cells inside the jelly like fluid that fills the eye known as the vitreous. The clumps of cells in the vitreous cast a shadow across the back of the eye causing the black spot or strand of hair appearance. Floaters will move around the eye when you move your eyes and may be more noticeable when looking at white walls or a blue sky.
Floaters are not usually a cause for concern, and there is generally no need to see your Optometrist or GP if you have had them for a long time and they are not getting any worse.
If any of the following symptoms occur, it is recommended to seek advice immediately from your Optometrist. It is important you advice as soon as you can. If you are unable to speak with your Optometrist, you should seek advice from your local eye casualty department;
Floaters appear suddenly.
The number or size of floaters increases.
You notice flashing lights.
You notice a shadow spreading across your vision.
How are floaters treated?
As floaters are not generally sight-threatening, treatment usually isn’t necessary. Over time, your brain learns to ignore the floaters so that you no longer notice them in your vision.
If you feel the floaters in your vision cannot be tolerated, you should seek advice from your Optometrist or GP who will be able to provide you with a referral to ACES, where our Specialist Clinicians can complete a comprehensive eye examination and recommend an appropriate clinical management plan.
