What Is Noninfectious Uveitis?
Uveitis is a type of eye inflammation that can cause vision loss if left untreated. While infectious uveitis is caused by bacteria, viruses, or fungi, noninfectious uveitis is a type of uveitis that is not caused by an infection. Instead, it is often associated with underlying autoimmune disorders, inflammatory conditions, or other systemic diseases.
In noninfectious uveitis, the immune system mistakenly attacks the healthy tissues in the eye, leading to inflammation and damage to the uvea, which is the middle layer of the eye. This can cause a range of symptoms, including eye pain, blurred vision, sensitivity to light, and floaters.
Noninfectious uveitis can affect anyone, but it is more common in people between the ages of 20 and 50. Women are more likely to be affected than men, and it is often seen in people with a history of autoimmune disorders, such as rheumatoid arthritis or lupus.
While the exact cause of noninfectious uveitis is not fully understood, research suggests that it may be linked to genetic factors, environmental triggers, and abnormalities in the immune system. In some cases, noninfectious uveitis may be associated with underlying conditions, such as sarcoidosis, multiple sclerosis, or inflammatory bowel disease.
Types of Noninfectious Uveitis
There are several types of noninfectious uveitis, each with its own set of characteristics and underlying causes. Here are some of the most common types:
Anterior Noninfectious Uveitis
This type of uveitis affects the front of the eye, specifically the iris and ciliary body. It is often associated with autoimmune disorders, such as rheumatoid arthritis, and can cause symptoms like eye pain, redness, and sensitivity to light.
Intermediate Noninfectious Uveitis
This type of uveitis affects the middle of the eye, specifically the vitreous humor and retina. It is often associated with conditions like multiple sclerosis and can cause symptoms like floaters, blurred vision, and eye pain.
Posterior Noninfectious Uveitis
This type of uveitis affects the back of the eye, specifically the choroid and retina. It is often associated with conditions like sarcoidosis and can cause symptoms like vision loss, blind spots, and eye pain.
Panuveitis
This type of uveitis affects all layers of the uvea, including the iris, ciliary body, choroid, and retina. It is often associated with severe inflammation and can cause symptoms like eye pain, vision loss, and sensitivity to light.
If you’re experiencing symptoms of noninfectious uveitis, it’s essential to seek medical attention from an eye care professional.

Causes of Noninfectious Uveitis
While the exact causes of noninfectious uveitis are still not fully understood, research has identified several factors that can contribute to its development. 🧬
Autoimmune Disorders
In many cases, noninfectious uveitis is associated with autoimmune disorders, where the immune system mistakenly attacks healthy tissues. Conditions like:
- Rheumatoid arthritis: This chronic inflammatory disorder can increase the risk of developing noninfectious uveitis.
- Vitiligo: This autoimmune skin condition can also contribute to the development of noninfectious uveitis.
- Psoriasis: People with psoriasis are more likely to develop noninfectious uveitis due to the shared autoimmune mechanisms.
Other Factors
In addition to autoimmune disorders, other factors can contribute to the development of noninfectious uveitis, including:
- Genetics: Having a family history of uveitis or other autoimmune disorders can increase the risk of developing noninfectious uveitis.
- Environmental triggers: Exposure to toxins, chemicals, or certain medications can trigger the condition in susceptible individuals.
- Vitamin D deficiency: Research suggests that low vitamin D levels may be associated with an increased risk of noninfectious uveitis.

Risk Factors for Noninfectious Uveitis
Noninfectious uveitis is a complex and multifactorial disease, and understanding the risk factors can help identify individuals who are more likely to develop this condition. While the exact causes of noninfectious uveitis are still not fully understood, research has identified several factors that may contribute to its development.
Age and Gender
Noninfectious uveitis can affect people of all ages, but it is more common in young and middle-aged adults. Women are more likely to develop noninfectious uveitis than men, especially during their childbearing years. This may be due to hormonal fluctuations, which can trigger an immune response and lead to inflammation in the eye.
Genetic Predisposition
Having a family history of uveitis or other autoimmune diseases can increase an individual’s risk of developing noninfectious uveitis. This suggests that there may be a genetic component to the disease, although the exact mechanisms are still unclear.
Environmental Factors
Environmental factors, such as exposure to toxins, smoking, and UV radiation, may also contribute to the development of noninfectious uveitis. For example, smoking has been linked to an increased risk of uveitis, possibly due to the toxic effects of cigarette smoke on the eyes.
Underlying Medical Conditions
Certain underlying medical conditions, such as rheumatoid arthritis, lupus, and multiple sclerosis, can increase the risk of developing noninfectious uveitis. This is because these conditions can trigger an immune response that leads to inflammation in the eye.
Diagnosing Noninfectious Uveitis
Diagnosing noninfectious uveitis can be challenging, as the symptoms can be similar to those of other eye conditions. A comprehensive eye exam and medical history are essential for an accurate diagnosis.
Eye Exam
A thorough eye exam typically includes a visual acuity test, refraction, and a dilated eye exam. During the dilated eye exam, the doctor will use eye drops to dilate the pupils, allowing them to visualize the retina and optic nerve. This can help identify signs of inflammation, such as vitreous haze or retinal lesions.
Imaging Tests
Imaging tests, such as optical coherence tomography (OCT) and fluorescein angiography, may be used to confirm the diagnosis and monitor the progression of the disease. These tests can help identify signs of inflammation, such as retinal thickening or leakage of fluid from the blood vessels.
Lab Tests
Lab tests, such as complete blood counts and inflammatory markers, may be ordered to rule out underlying infections or inflammatory conditions. These tests can help identify signs of inflammation, such as elevated white blood cell counts or increased levels of inflammatory markers.
Early diagnosis and treatment of noninfectious uveitis are crucial to preventing vision loss and reducing the risk of complications. If you suspect you or a loved one may have noninfectious uveitis, don’t hesitate to consult an eye care professional for a comprehensive evaluation and treatment plan. 🙏
