Vitreous Opacities & Lesions: Causes, Symptoms & Treatments
Ageing affects every part of the body, but it can cause changes in the eyes more commonly and earlier than other areas.
One of the most common symptoms of ageing is the appearance of “floaters” in the field of vision. These are also known as vitreous opacities. They typically will appear as thread-like strands, squiggly lines, specks, “flies”, “spiders” and – in extreme cases – as “cobwebs”.
Floaters appear to move with the eye’s movement, so they appear to dart away when you try to look at them directly. But vitreous opacities don’t follow eye movements exactly and they can seem to continue to drift after you stop moving your eyes.
Eye Lesions are abnormal tissues on the eye. They typically develop after a trauma to the eye or as a symptom of some other health issue. Common symptoms of lesions include dry or red eyes, eye pain, and blurred vision that can’t be corrected with lenses.
Eye lesions can grow quite large in size, becoming more easily noticed, more irritating, and in some cases leading to the loss of sight. In rare cases, they can contain cancerous qualities, but usually they are relatively benign.
Causes of Floaters
There are several potential causes of floaters, including:
- Ageing – As the eye grows older, it undergoes normal degenerative changes, such as translucent opacities
- Posterior vitreous detachment
- Vitreous Bleeding – Minor bleeds are seen as spots in the vision, although major bleeds can cause more serious decreases in the ability to see
- Vitritis – A condition caused by an irritation to the cells in the vitreous due to uveitis
- Asteroid Hyalosis – Small yellow and white particles scattered throughout the vitreous. This condition is usually benign
- Amyloidosis – Sheet-like opacities
- Tumours – In people with cancers such as lymphoma, floaters can appear as a result of vitritis
In about 25% of cases, floaters are attributed to a degeneration of the vitreous, where collagen fibres become thickened with vitreous liquidation and then become visible.
Typically, this develops gradually. It’s a perfectly normal effect of ageing and there typically is no threat to eye health unless the situation deteriorates. These types of vitreous opacities tend to settle at the bottom of the eye, below the line of sight, so they become less distracting.
While most people eventually ignore them, they can become seen when looking at bright objects, such as a white sheet of paper or on a sunny sky. They are most common among older adults, as well as in people who have short-sightedness (myopia), are diabetic, or have had a cataract operation.
A related condition to vitreous opacities and lesions are haloes. These occur when light passing through water in or on the surface of the eye is broken down into its spectral colours, just like a rainbow. When this occurs, the viewer can see rainbow-like rings around lights or brightly lit objects.
The most common cause of haloes is acute angle-closure glaucoma, which is a condition that can seriously threaten your eyesight. But haloes have other causes, including:
- Over-production of tears
- Oedema of the corneal epithelium due to wearing contact lenses too long
- Late-stage corneal dystrophies
- Early cataracts
- Pigment dispersion syndrome
- Vitreous opacities
Haloes can also be seen by some people when they use drugs containing digitalis and chloroquine.
Ethos Bright Eyes drops are a specialised eye drop treatment that can effectively treat vitreous opacities, lesions, and haloes. Applying just a few drops of Bright Eyes to your eyes daily can help improve eye health and eliminate the conditions that can lead to these eye disorders, as well as relieving their symptoms including; eye irritation, dryness, redness and pain.
If you want to avoid experiencing any symptoms of vitreous opacities and lesions, then you need to use Bright Eyes eye drops. They give your tired, aching eyes the relief they need before temporary or permanent damage can occur.
