The eyes are important organs that help us see the world around us. However, as we enter middle age or old age, many people may begin to experience problems seeing floaters, black spots, or black lines drifting around, similar to cobwebs in the visual field, which are symptoms of “vitreous degeneration.” Although this condition is common and usually not seriously dangerous, it can affect quality of life and work performance.
What is vitreous degeneration? What causes it? What symptoms should raise suspicion? Are there ways to prevent or treat it? To take care of eye health and maintain good vision quality.

What is the vitreous humor?
The vitreous humor is a clear, colorless gel-like substance inside the back part of the eyeball. It has a volume of about 4 milliliters, or approximately 80% of the total volume of the eyeball. The vitreous consists of 95-98% water and other substances including collagen, hyaluronic acid, and various proteins.
The important functions of the vitreous humor include serving as a medium for light and images to pass through to the retina, as well as
- Maintaining the shape of the eyeball
- Helping nourish the lens and retina
- Protecting the eye from impact
What is vitreous degeneration?
Vitreous degeneration is a condition where changes occur in the vitreous humor, the clear gel-like component inside the eye. When degeneration happens, the vitreous changes from a viscous, clear gel to a more liquid state, causing proteins and collagen fibers to clump into small particles floating in the vitreous. This results in shadows or floaters that look like cobwebs in the visual field. Vitreous degeneration is a natural aging process usually seen in people over 40 years old but can also occur in younger individuals with risk factors such as high myopia or eye trauma.
Symptoms of vitreous degeneration that can be observed
Common symptoms found in people with vitreous degeneration
- Visual symptoms
- Seeing black spots or floaters in the visual field
- Seeing thread-like fibers resembling spider webs drifting around
- Seeing rings or various shapes floating in the visual field
These symptoms are usually more noticeable when looking at a white or bright background
- Characteristics of vision
- Floaters may move with eye movement, a condition called Posterior Vitreous Detachment (PVD), caused by the vitreous pulling away
- Symptoms may worsen when looking at computer screens or the sky
- Sometimes flashes of light or flickers may be seen
When should you see a doctor?
- If the number of black spots appearing is unusually high or persists for a long time
- If you see flashes of light resembling lightning or flashes
- If you see a dark curtain blocking vision, causing problems in daily life
Dangers and adverse effects of vitreous degeneration
Vitreous degeneration can affect daily life in many ways, such as vision, psychological impact, or other complications.
Impact on vision
- Interferes with reading or work that requires intense visual focus
- May cause eye fatigue easily
- Affects driving or activities requiring precise vision
Psychological impact
- Causes anxiety about eye health
- Reduces confidence in performing various activities
- May cause depression in some cases
Regarding the dangers of vitreous degeneration that many worry about when symptoms first appear, the severity and adverse effects vary by case. Some cases of vitreous degeneration are harmless, but others may develop complications involving the retina, increasing the risk of retinal tears or detachment, which can severely affect retinal function and potentially lead to blindness.
What causes vitreous degeneration?
- Aging: As age increases, natural degeneration of the vitreous occurs in everyone due to collagen fiber deterioration, similar to collagen degradation under the skin that causes wrinkles and loss of elasticity.
- High myopia : In cases of high myopia, especially those with myopia over 600 diopters, the eyeball is elongated. Eye movements cause the vitreous to swing more than in normal eyes, accelerating collagen fiber degeneration.
- Eye injury: Eye surgery or severe trauma such as being hit, punched, or falling can cause earlier vitreous degeneration and increase the risk of retinal tears or detachment in the future.
- Diabetes and hypertension: In people with diabetes or high blood pressure, small blood vessels can become fragile, rupture, leak, or become blocked easily. Especially in diabetic retinopathy, bleeding into the vitreous from ruptured retinal vessels can rapidly cause vitreous degeneration.
- Inflammation of the vitreous and retina (Intermediate and Posterior Uveitis) : Caused by immune system inflammation, infections, or other physical conditions such as cancer.
Can vitreous degeneration be prevented?
Vitreous degeneration is a normal condition that occurs naturally with aging, but it can be prevented or slowed down by self-care as follows:
General eye health care
- Get enough rest for your eyes
- Avoid prolonged continuous use of your eyes
- Wear sunglasses when outdoors
- Protect your eyes from trauma to reduce the risk of vitreous degeneration
Diet
- Focus on foods rich in vitamins A, C, and E
- Eat vegetables and fruits high in antioxidants
- Drink enough water
Behavioral changes
- Reduce smoking
- Control blood sugar levels
- Exercise regularly
Advice: Avoid rubbing your eyes hard or pressing/massaging the eyeballs, as this can cause vitreous degeneration and tears. Eye health should be checked at least once a year, especially if you are over 40 and have never had an eye exam. Early eye exams can assess the risk of eye diseases. In cases diagnosed with diabetes, eye exams should be done to detect diabetic eye diseases such as vitreous degeneration, early cataracts, and diabetic retinopathy.
How to know if you have vitreous degeneration? What are the examination methods?
If you suspect vitreous degeneration, it is recommended to see a doctor for proper diagnosis, which can be done by several methods such as:
- Basic examination: includes history taking, vision testing, and external eye examination
- Specialized examination: such as retinal examination with special instruments, retinal imaging, and high-frequency ultrasound examination
How is vitreous degeneration treated?
Once diagnosed with vitreous degeneration, treatment depends on the severity of symptoms, such as:
Supportive treatment: If there are only a few floaters, doctors will advise patients to adapt and learn to live with the symptoms. Using appropriate glasses and adjusting the work environment can help reduce floaters or shadows without further treatment.
Medical treatment: If symptoms are severe or there are retinal tears, doctors may recommend laser treatment or vitrectomy surgery in severe cases.
Q&A about vitreous degeneration
What to eat to nourish vitreous degeneration
According to scientific evidence, there is no definitive way to slow down vitreous degeneration through diet. However, risk factors for physical degeneration can be reduced by wearing sunglasses to protect against UV rays, eating a nutritious diet, avoiding smoking, and limiting alcohol consumption.
Can floaters in the eye go away on their own?
In mild cases, early-stage vitreous degeneration causes floaters or thread-like shapes that move with eye movement. Changing behavior can lead to spontaneous improvement. However, if complications such as retinal degeneration or tears occur, and floaters increase rapidly, vision blurs, or frequent flashes of light appear at night or in the dark, prompt medical attention is necessary for appropriate treatment.
What kind of glasses should be worn for vitreous degeneration?
For those with vitreous degeneration who engage in activities that affect the eyes, protective glasses such as polycarbonate lenses, which are clear and very durable, are recommended to prevent eye injuries. For daily life, wearing sunglasses outdoors to protect against UV light is advised, as UV rays can accelerate vitreous degeneration.
Summary: Vitreous degeneration can be managed and prevented
Vitreous degeneration is a common condition that occurs with aging. Although it may not be entirely preventable, its progression can be slowed by maintaining good eye health, eating nutritious food, and having regular eye exams at least once a year, especially for diabetics, to reduce risks and severity of symptoms.
