Serpiginous Choroidopathy (SC) is a chronic inflammatory eye condition that requires diligent monitoring and tailored management. Find expert eye care specialists listed with Specialty Vision who can help manage SC and protect your vision.
Serpiginous Choroidopathy (SC) is a rare, bilateral, chronic inflammatory condition that affects the retinal pigment epithelium (RPE), choriocapillaris, and the choroid. This disease, although infrequent—accounting for less than 5% of posterior uveitis cases—tends to impact young to middle-aged adults, with a higher prevalence in men. Recognizing SC is important because its recurring nature requires careful monitoring and tailored management to protect vision.
At its core, SC is characterized by a progressive and recurrent inflammation that damages the back layer of the eye. The disease appears as gray-yellowish subretinal infiltrates that spread in a serpentine, or snake-like, pattern around the optic disc. Here’s the thing—while the precise etiology remains unknown, researchers believe that SC likely has an immunogenic foundation. The condition often responds to treatments that include corticosteroids and other immunosuppressants, supporting the theory of its immune-related origins.
SC stands apart as a unique clinical entity among inflammatory eye disorders. It starts with a primary inflammatory reaction in the RPE, choriocapillaris, and choroid—a process that eventually leads to retinal damage. In active cases, the lesions display a leading edge and gradually resolve with the development of atrophy in the RPE and choriocapillaris. With repeated episodes, these atrophic changes accumulate, producing areas of both hypo- and hyperpigmentation. Although the exact trigger remains elusive, some studies have noted associations with HLA-B7 and retinal S-antigen reactivity, hinting at a probable immune-mediated mechanism.
While some researchers have speculated about a connection between SC and infectious agents like Mycobacterium tuberculosis or herpes viruses, these associations are not yet confirmed. Instead, many specialists view SC as an autoimmune process. It is essential to differentiate SC from similar conditions, such as tuberculosis-related serpiginous-like choroidopathy (SLC), which mimic SC in appearance but differ significantly in their management.
SC is considered a condition that most commonly impacts young to middle-aged adults, with a notable predisposition in men. Despite its rare occurrence, SC can have devastating effects on vision if not properly managed. There are no well-established links with systemic diseases, and the absence of systemic associations requires our retina specialists to focus solely on ocular manifestations and related complications when evaluating and treating the condition.
Patients with SC may notice subtle changes in their vision that can initially be overlooked. Here’s what to keep an eye out for:
Typically, one eye may begin to experience a reduction in vision without any associated pain.
This term refers to distortions in vision where straight lines may appear wavy or bent.
These are blind spots that develop around the central field of vision, alerting patients to possible retinal involvement.
The lack of discomfort can sometimes delay patients in seeking care, which makes periodic retinal evaluations crucial, especially if you notice any changes in your sight.
In clinical practice, the appearance of SC on eye examinations is quite distinctive. When performing a fundus evaluation, our retina specialists look for gray-yellowish subretinal lesions that originate near the optic disc and spread outward in a serpentine fashion. These lesions can be active or inactive, and recognizing their stage is paramount to guiding treatment.
Active lesions, with their leading edge inflammation, present a risk when they approach the fovea—the central area responsible for high-acuity vision. Conversely, inactive areas appear dark and uniformly hypoautofluorescent in imaging studies, highlighting the areas where tissue damage has already occurred. This contrast in lesion appearance aids in monitoring the progression of the disease over time.
When SC is suspected, a range of imaging techniques is employed to confirm the diagnosis and assess the extent of retinal damage. Here’s a summary of the diagnostic tools our retina specialists may use:
FA is pivotal in highlighting early hypofluorescence in active lesions that later show leakage. This pattern correlates with the inflammatory activity at the lesion margins.
ICG provides a different perspective by consistently revealing hypofluorescence throughout the active period of lesions, thereby underlining the extent of choroidal involvement.
This minimally invasive test has become increasingly useful for monitoring SC. Active lesions show a distinct hypoautofluorescent halo, while semi-active areas display a linear hypoautofluorescence, and inactive zones become uniformly dark.
Using these imaging techniques in combination offers a detailed view of the lesion characteristics. This step is essential in distinguishing SC from other similar-appearing conditions and in formulating an effective management plan.
There are several conditions that can mimic the appearance of SC, which necessitates a careful approach to diagnosis. Differential diagnosis is a challenge because many of these conditions share overlapping features. For instance, other causes of posterior uveitis, such as multifocal chorioretinitis, acute posterior multifocal placoid pigment epitheliopathy (APMPPE), and infectious causes like toxoplasmosis or tuberculosis, may resemble SC on preliminary examination.
One related condition is serpiginous-like choroidopathy (SLC), particularly associated with tuberculosis. Unlike classic SC, SLC often shows lesions that are not contiguous with the optic disc, tend to be multifocal or more peripheral, and may spare the central vision even when the macula is involved. Importantly, while SC generally responds well to corticosteroids and immunosuppressants, SLC requires additional antibacillary treatment combined with oral corticosteroids to avert recurrences.
This distinction is not just academic—it directly influences treatment decisions. Our retina specialists emphasize the importance of TB testing, such as tuberculin skin testing or the QuantiFERON-TB Gold test, particularly for patients originating from regions where tuberculosis is common. Accurate diagnosis ensures that the patient receives the appropriate therapy and avoids potential complications from a misdiagnosis.
Treatment of Serpiginous Choroidopathy focuses on halting the progression of chorioretinal inflammation, especially when active lesions threaten the fovea. The primary goal is to preserve as much vision as possible while preventing recurrence. Systemic and periocular corticosteroids remain the frontline treatment option; however, given the chronic and recurrent nature of the disease, long-term management often requires steroid-sparing agents. Our retina specialists might recommend medications such as antimetabolites (for example, methotrexate, mycophenolate mofetil, or azathioprine), cyclosporine A, or even anti-TNF agents like adalimumab or infliximab—once it has been confirmed that tuberculosis is not a contributing factor.
Managing SC is challenging because its relapses can occur over variable intervals, ranging from months to years. The intermittent nature of these recurrences means that even when symptoms temporarily recede, patients still need regular follow-up evaluations and imaging tests to monitor the disease’s course. This vigilance is important since, in up to 25% of cases, final visual acuity may drop to less than 20/200, underscoring the need for early detection and careful management.
One of the pressing concerns about SC is the development of complications that can further compromise vision. The most frequently encountered complication is choroidal neovascularization (CNV), which affects up to 35% of patients. CNV refers to the formation of new, abnormal blood vessels beneath the retina, which may leak and result in further vision loss.
Additional complications include:
Scar tissue can form under the retina, further impairing vision.
Fluid accumulation in the macula can disrupt the central vision important for reading and other activities.
Blockage of small retinal veins that can complicate the picture by adding vascular issues.

Separation of the retina from its underlying layers that, if left untreated, may lead to significant visual impairment.
Abnormal new vessels might also form on the optic disc, posing a further risk to vision.
Although less common, inflammation in the front part of the eye may also occur.
These complications underscore the importance of regular monitoring and timely intervention. If you notice any changes in your vision or if symptoms seem to progress, do not hesitate to call our office for a comprehensive evaluation.
Serpiginous Choroidopathy is often described as a progressive disease with a relapsing-remitting course. This means that while there are periods of significant inflammation, there may also be intervals where the disease appears quiet. However, even during these quieter phases, microscopic or subtle changes may be slowly occurring in the back of the eye. That’s why our retina specialists recommend periodic imaging using techniques like FAF, which can detect even minor alterations in the retinal structure.
Over time, repeated bouts of inflammation lead to accumulation of retinal atrophy. This results in mixed patterns of pigmentation that can be detected as both darkened (hypopigmented) and lightened (hyperpigmented) areas in the retina, reflecting the history of the disease’s activity. It’s a sign that while some lesions resolve, they leave behind a permanent imprint of damage that requires lifelong monitoring.
Understanding Serpiginous Choroidopathy and its management can help reduce anxiety and set realistic expectations about the course of the disease. While the diagnosis may sound concerning, knowing that effective management strategies are available can be a comfort. Regular follow-up visits with our retina specialists are critical; during these consultations, they will conduct imaging tests and adjust treatment plans as needed to tackle any new lesions or recurrences as early as possible.
It’s also important to note that while the initial presentation might involve a sudden drop in vision in one eye, the disease is typically bilateral, though often asymmetrical. This means that the unaffected eye might serve as a window for early detection, prompting timely intervention before both eyes are significantly impacted.
Our approach to managing SC is comprehensive. We aim to not only address the inflammation with medications but also to carefully monitor for complications like CNV, which could lead to further visual decline. This commitment is why regular eye examinations and imaging assessments are crucial components of your overall treatment plan.
Due to the overlapping features of several ocular inflammatory conditions, it is essential to consider other possible diagnoses when encountering signs that resemble SC. One notable differential is serpiginous-like choroidopathy (SLC), which is particularly associated with tuberculosis. While SC and SLC share similar clinical findings, certain features can help distinguish them:
These distinctions are clinically significant because they affect treatment choices. In cases of SLC, antibacillary therapy combined with oral corticosteroids is usually necessary to prevent recurrences. This remains different from the standard management for classic SC. It is why our retina specialists advocate for thorough tuberculosis testing as part of the diagnostic process, especially for patients who live in or have traveled to areas where tuberculosis is endemic.
The chronic nature of Serpiginous Choroidopathy necessitates a proactive and customized long-term management strategy. Our retina specialists work together with you to design a treatment regimen that not only controls the active inflammatory process but also minimizes the risk of recurrences. This often involves the use of immunosuppressive therapies beyond corticosteroids—a vital step, particularly when repeated relapses are a concern.
Monitoring the disease over time is equally important. During routine check-ups, detailed imaging studies such as FA, ICG, and FAF will be performed to help map out any changes in the retinal profile. These tests allow for a better understanding of the extent of atrophy and the subtle transitions between active, semi-active, and inactive lesions. With this ongoing evaluation, our retina specialists can timely adjust therapy to ensure that inflammation is kept in check and complications are prevented.
In addition to medical therapy, lifestyle adjustments such as a healthy diet rich in antioxidants and the maintenance of regular eye exams can support overall retinal health. These complementary strategies are part of a holistic approach intended to preserve vision and enhance quality of life, despite the challenges that SC may pose.
The treatment journey for SC is highly individualized, taking into account the extent of retinal involvement, the proximity of active lesions to critical areas like the fovea, and the patient’s overall health. As mentioned earlier, initial management typically starts with corticosteroids to calm the inflammation. However, long-term suppression of disease activity often demands the use of steroid-sparing agents. Our retina specialists might recommend one or more of the following options based on your specific situation:
Medications such as methotrexate, mycophenolate mofetil, or azathioprine work by reducing immune system activity, thereby diminishing the frequency and severity of SC recurrences.
Cyclosporine A can be beneficial as it modulates immune responses and minimizes inflammatory damage in the retina.
In certain cases, agents like adalimumab or infliximab are considered to target inflammatory mediators directly, particularly after confirming that an infectious trigger like tuberculosis is not involved.
Because SC is a chronic condition, these treatments are not curative but are instrumental in controlling inflammation and preserving as much vision as possible. Frequent reassessment allows for dose adjustments or therapy modifications—ensuring that the treatment aligns closely with how the disease behaves in your eye. It’s a dynamic process that depends partly on regular communication and follow-up visits.
It’s important to have realistic expectations when managing Serpiginous Choroidopathy. The disease is often unpredictable with intervals of activity that can vary greatly between individuals. While some patients maintain relatively good vision over the long term, others may experience significant visual decline, especially if complications such as choroidal neovascularization occur.
Studies have shown that up to 25% of eyes affected by SC may ultimately achieve a final visual acuity lower than 20/200. This statistic highlights the significance of early detection and aggressive management of active lesions. Although the prognosis can be challenging, our retina specialists strive to minimize the progression of retinal damage through careful monitoring and individualized treatment strategies.
Looking ahead, advances in imaging and treatment are promising. The integration of newer diagnostic tools and a better understanding of immunologic markers associated with SC pave the way for more targeted therapies. This ongoing evolution in care provides hope that management will continually improve, preserving vision and quality of life for those affected by this complex condition.
