Posterior uveitis, or choroiditis, is an eye condition affecting the choroid and retina. It can potentially cause serious vision issues if not treated quickly. Find leading retina specialists listed with Specialty Vision to get the care you need.
Posterior uveitis, often known as choroiditis when it directly involves the choroid and retina, is an inflammation that targets the back parts of your eye. This condition is particularly significant because the choroid plays a vital role in nourishing the retina, the light-sensitive tissue responsible for sending images to the brain. Understanding this condition is essential as it can affect vision if left untreated.
At its core, posterior uveitis refers to inflammation that occurs in the posterior segment—the choroid and retina—of the eye. The choroid is a rich layer of blood vessels located between the retina and the sclera (the white outer layer of the eye), and it is crucial for supplying nutrients and oxygen to the retina. When this area becomes inflamed, it can lead to significant vision problems, ranging from blurred vision and floaters to, in severe cases, permanent vision loss. This inflammation can be triggered by a variety of factors, and its impact depends on both the severity and underlying cause. Posterior uveitis is sometimes referred to as chorioretinitis, highlighting how both the choroid and retina can be affected by the inflammatory process. The potential for serious complications underscores the importance of early detection and proper management by our retina specialists.
Let’s break it down in simple terms. The retina is like the film in a camera—it captures images and sends them to your brain. The choroid, on the other hand, acts more like a nourishing support system, providing essential nutrients and oxygen through its dense network of blood vessels. When inflammation disrupts the vital exchange of nutrients, the retina may not function as effectively, which can lead to various vision problems.
This integrated relationship between the retina and the choroid is why damage to this area through conditions such as posterior uveitis can be so concerning. When the inflammation is intense or remains unchecked, it can develop into what we refer to as chorioretinopathy—a state where the damage to the eye’s tissues becomes more pronounced and potentially permanent.
One of the best ways to safeguard your vision is by being aware of the signs of posterior uveitis. Here’s the thing: changes in vision or discomfort in the eye can be an early indication that something isn’t quite right. Our retina specialists stress the importance of routine check-ups, especially if you notice any unusual symptoms.
You might see small, dark spots or threads drifting across your field of vision.
A sudden appearance of flashes could signal a problem in the back of your eye.
Persistent redness, particularly when accompanied by pain, is a warning sign.
Vision that suddenly becomes less clear is a key symptom of inflammation in the retina or choroid.
Everyday brightness might seem overwhelming or painful.
Increased watering of the eyes can be another indicator that something is off.
If colors appear faded or altered, it may mean that the retina is not functioning optimally.
Any discomfort or pain in your eye should be taken seriously.
These symptoms may seem alarming if you experience just one or two, but remember that early detection leads to better outcomes. If any of these signs pop up, it’s always a good idea to consult with our retina specialists for a thorough evaluation.
In many cases, chorioretinitis is triggered by an infection. These infections might be present at birth (congenital) or acquired later in life. The most common infectious culprit is toxoplasmosis, which is known to affect the eye by causing localized inflammation. However, several other pathogens also play a role:
This bacterial infection can extend its impact to the eye, leading to inflammation.
Particularly in individuals with weakened immune systems, CMV can cause inflammatory changes in the retina.
A bacterial infection that, if untreated, can affect multiple systems including the eyes.
Viruses like Zika, rubella, and varicella-zoster have been identified as potential causes of chorioretinitis.
Though less common, fungal pathogens can also provoke a similar inflammatory response in the eye.
Each of these infections disrupts the normal functioning of the choroid and retina differently, yet all share the common result of inflammation that compromises the essential nutrient supply to the retina. The specific approach to treatment will depend on identifying which infectious agent is responsible.
Not all cases of posterior uveitis stem from infections. Non-infectious factors like injuries or autoimmune responses also contribute to this condition. In these scenarios, the body’s immune system mistakenly targets its own tissues, leading to inflammation and potential tissue damage.
Trauma or direct injury to the eye can instigate an inflammatory response.
Conditions such as rheumatoid arthritis, sarcoidosis, and Behçet’s disease can trigger inflammation that affects the choroid and retina.
Certain types of cancer, including lymphoma or metastatic diseases, can have manifestations that involve the eye.
Some inherited conditions may predispose an individual to inflammation of the posterior eye.
While these non-infectious scenarios differ from infection-based inflammation, they can be equally problematic if not addressed promptly. Our retina specialists work closely with specialists across multiple fields to manage these conditions effectively, ensuring your treatment plan is comprehensive and tailored to your specific situation.
Any time the retina or choroid is involved in inflammation, the stakes for maintaining visual clarity become higher. One of the most concerning aspects of untreated posterior uveitis is that it may lead to permanent vision loss.
When the inflammation becomes severe, it may develop into chorioretinopathy, a condition where infection or inflammation actually damages tissue within the choroid and retina. If the damage progresses, a complication known as chorioretinal atrophy may occur. This atrophy means that parts of the retina or choroid may shrink or not work as efficiently as they once did. Even subtle changes in these tissues can have a big impact on how well your eye functions, emphasizing the importance of early diagnosis and consistent treatment.
It’s important to note that with modern medical approaches, many cases of posterior uveitis can be managed effectively. When the condition is caught early and treatment is tailored to your needs, the outlook is generally positive. Nonetheless, untreated or poorly managed inflammation can indeed lead to significant visual impairment, which is why routine eye examinations are so critical.
Detecting posterior uveitis early is key to preventing damage and preserving vision. Our retina specialists use a variety of diagnostic tests to get an in-depth look at what’s happening inside your eye. The process often begins with a comprehensive dilated eye exam, which allows your provider to observe the back of your eye with greater detail.
In addition to the exam, several imaging tests help paint a clearer picture of the condition:
This non-invasive imaging test uses light waves to capture cross-sectional images of your retina, allowing for a detailed view of its layers.
During this test, a dye is used to highlight the blood vessels in the retina. This can reveal areas where the vessels are leaking or damaged.
Similar to fluorescein angiography, this test focuses on the choroidal blood vessels. It provides essential information about the circulation within the choroid.
In some cases, a sample or swab from the eye may be analyzed to detect specific infections that could be causing the inflammation.
Each of these tests is chosen based on the particular presentation of symptoms and the suspected cause of your condition. By combining these approaches, our retina specialists can create a clear picture of how the choroid and retina are being affected and devise an appropriate treatment plan.

Treating posterior uveitis (choroiditis) involves addressing both the inflammation and its underlying causes. For many cases, the first line of treatment includes the use of steroids. These medications help reduce inflammation quickly and can preserve vision if started promptly. However, steroids can only be used for a short duration because of potential side effects. That’s why our retina specialists often collaborate with specialists in inflammatory diseases to introduce steroid-sparing medications. These medications work by suppressing the immune system in a gentler way, reducing long-term inflammation without over-relying on steroids.
If an infection is the root cause, you will likely be prescribed medications that target that specific pathogen. Depending on which infectious agent is involved, your treatment may include:
To treat bacterial infections such as tuberculosis or bacterial-induced toxoplasmosis.
For infections caused by viruses like cytomegalovirus, herpes viruses (including varicella-zoster), or others.
When fungal infections are identified as the source of the inflammation.
These are used particularly in cases where toxoplasmosis is diagnosed, as this parasitic infection is a well-known cause of chorioretinitis.
In very rare instances, and only when other treatments are not sufficiently effective, a surgical procedure known as vitrectomy may be recommended. This surgery involves removing the fluid and debris from the eye, helping to clear the path for vision and reduce inflammation. Ultimately, the management of posterior uveitis is highly individualized. Your specific treatment plan will be designed based on the severity of the inflammation, the underlying cause, and how your eye is responding to therapy. Consistent communication with our retina specialists is key—they will guide you every step of the way and adjust treatments as needed.
The road to recovery and ongoing management of posterior uveitis begins with staying proactive about your eye health. Regular visits with our retina specialists are crucial not only for monitoring the condition’s progress but also for catching any potential complications early. Think of these appointments as critical check-ups that help keep your vision in optimal focus.
