The primary autoimmune condition causing floaters is uveitis, inflammation of the eye's middle layer (uvea), leading to inflammatory cells in the vitreous gel, appearing as floaters, often with redness, pain, and light sensitivity, and linked to systemic diseases like ankylosing spondylitis, juvenile idiopathic arthritis, and multiple sclerosis (MS). Susac's Syndrome, attacking blood vessels in the brain, retina, and inner ear, also causes floaters, alongside other severe vision/hearing issues.
Severe inflammation in the eye can cause white blood cells to enter the vitreous, and this can look like floaters. These are more common in patients with autoimmune diseases like lupus or sarcoid.
Inflammation in the back of the eye.
Posterior uveitis affects the back of the eye, which includes the retina and an eye layer called the choroid. The inflammation causes floaters in the vitreous. Causes of posterior uveitis include infection, autoimmune disorders and inflammatory diseases.
Symptoms. Patients with uveitis may experience sudden, acute symptoms that include eye pain, redness, sensitivity to bright lights, blurred vision and "floaters" that partially obscure vision. Uveitis may also have a chronic, silent course, in which patients do not have any noticeable symptoms.
Certain conditions that affect the whole body can also cause changes in the eyes, including the appearance of floaters. For instance, conditions that cause inflammation throughout the body, such as lupus or rheumatoid arthritis, can also cause inflammation in the eyes, leading to uveitis and floaters.
Lupus eye problems can range from dryness to inflammation to sudden floaters, often appearing without warning. Knowing what to look for and having regular eye exams can make a big difference.
Early eye symptoms of MS often involve optic neuritis, causing blurred vision, pain with eye movement, temporary vision loss (often in one eye), reduced color vision (especially reds), blind spots, or flickering lights; other common issues are double vision (diplopia) from uncoordinated eye muscles and involuntary rapid eye movements (nystagmus). These visual disturbances can be sudden, affect one eye more than the other, and may be the first noticeable sign of MS, but they aren't exclusive to it.
Three key signs of Sjögren's syndrome are dry eyes, dry mouth, and chronic fatigue, stemming from the autoimmune system attacking moisture-producing glands, leading to gritty, burning eyes, difficulty swallowing or speaking, and persistent tiredness, often accompanied by joint pain and swollen glands.
OCT scanning allows us to see what's going on beneath the surface of the eye, which may be useful for detecting conditions — including autoimmune eye diseases — that don't have many noticeable symptoms in the early stages.
Patients with lupus may develop dry eye symptoms, which is also known as dry eye syndrome. Dry eye syndrome is a condition where symptoms of dry eyes become severe, which often cause discomfort for the patients, such as a gritty sensation in the eyes, itching, and burning.
Lots of people, particularly older people, get floaters and flashes. They're usually caused by a harmless process called posterior vitreous detachment (PVD), where the gel inside your eyes changes. Sometimes they can be caused by retinal detachment. This is serious and can lead to permanent vision loss if not treated.
Eye melanoma may not cause any symptoms. When they do happen, signs and symptoms of eye melanoma can include: Flashes of light or what look like specks of dust in a person's vision. These are sometimes called floaters.
They are dots or specks in your vision that seem to disappear when you try to look directly at them. They often appear as circular dots but can also be small lines, rings or other irregular shapes – or portions of the field of vision which appear to be slightly blurry.
Common Autoimmune Disease Symptoms
Eye symptoms may include: A dark area in part(s) of your visual field. A visual disturbance described as “a dark shade or curtain” covering part of your vision. Loss of peripheral (side) vision.
The "worst" autoimmune diseases are subjective but often ranked by severity, impact on life expectancy, and organ damage, with top contenders including Giant Cell Myocarditis (deadly heart inflammation), Vasculitis (blood vessel inflammation like GPA), Systemic Lupus Erythematosus (multi-organ attacks), Multiple Sclerosis (nervous system damage), and Type 1 Diabetes (pancreas destruction). These conditions can severely affect quality of life, cause permanent disability, and reduce lifespan if not managed effectively, though rare ones like Giant Cell Myocarditis are acutely fatal.
Neuromyelitis optica is an autoimmune disorder that affects the nerves of the eyes and the central nervous system, which includes the brain and spinal cord. Autoimmune disorders occur when the immune system malfunctions and attacks the body's own tissues and organs.
Lupus, a chronic autoimmune condition, can affect various organs and tissues in the body, including the eyes. Eye floaters, visual disturbances characterized by tiny specks or cobweb-like shapes that drift in the line of vision, are a common ocular manifestation in individuals with lupus.
Sjogren's (SHOW-grins) syndrome is a disorder of your immune system identified by its two most common symptoms — dry eyes and a dry mouth. The condition often accompanies other immune system disorders, such as rheumatoid arthritis and lupus.
You can get it at any age, but it is most common in people in their 40s and 50s. Sjogren's syndrome is more common in people who have other autoimmune diseases such as rheumatoid arthritis and lupus.
Specific Tests for Sjögren's Syndrome
Your doctor may recommend some or all of the following tests: Blood and urine tests, to look for the presence of antibodies common in Sjögren's syndrome. The results of an ANA (antinuclear antibody) test will determine if you have an autoimmune disorder.
Symptoms of multiple sclerosis (MS)
Visual disturbances are often associated with neurological disorders such as double vision, nystagmus, reduced visual field and acuity, a full or total loss of vision due to papilledema (or a swollen optic disc).
The 'MS hug' is symptom of MS that feels like an uncomfortable, sometimes painful feeling of tightness or pressure, usually around your stomach or chest. The pain or tightness can feel like a tight band stretching under your breasts, around the ribs and back or stomach, or it can be just on one side.
