Serpiginous Choroiditis: Symptoms, Causes and Types

Serpiginous Choroiditis is a rare eye disorder that affects the choroid, the layer in the rear of the eye that supplies nourishment to the retina. It is mostly caused by an aberrant immunological response, in which the body's defense system incorrectly targets the choroidal tissues, resulting in inflammation, scarring, and potential vision loss. In some cases, Serpiginous Choroiditis tuberculosis has been linked to the disease, especially in regions where tuberculosis is common.

Doctors often use advanced imaging techniques like Serpiginous Choroiditis autofluorescence to detect early changes in the retina and choroid, helping with diagnosis and treatment planning. This condition generally affects adults between 20 and 70 years of age, with no particular preference for gender. Early detection and timely treatment are essential for preserving vision and preventing further complications.

What are the Symptoms of Serpiginous Choroiditis?

Patients may experience blurry vision, seeing dark spots, or distortions in their sight. Here are most common serpiginous choroiditis symptoms:

Patients may experience floaters or dark spots in their vision, which can be bothersome and impact daily activities.
Eye pain or discomfort, often described as a dull ache, can be present in individuals with Serpiginous Choroiditis.
Photophobia, or sensitivity to light, may be heightened in those with this condition, leading to discomfort in bright environments.
Distorted or wavy vision is another symptom of Serpiginous Choroiditis, affecting the quality of visual perception in affected individuals.

If you notice any of these symptoms, it's important to see an eye specialist for diagnosis and treatment to help preserve your vision and prevent complications.

Causes of Serpiginous Choroiditis

Serpiginous choroiditis is a rare but serious eye condition that leads to progressive inflammation in the choroid and retina. While the exact reason behind it is not fully understood, several factors have been found to contribute to its development. Serpiginous choroiditis causes may include genetic factors, autoimmune disorders, infections, environmental triggers, and issues with the immune system. Knowing these causes can help in early diagnosis and better treatment.

Genetic Factors

Some people may be more prone to this condition due to their genes.
If there is a family history, the risk might be higher.

Autoimmune Disorders

Diseases like sarcoidosis can lead to inflammation in the eye.
Other immune-related conditions may also contribute to the problem.

Infections

Tuberculosis (TB): A common infection in India, TB can affect the choroid and cause inflammation.
Syphilis: Though less common, this infection can also lead to serpiginous choroiditis.

Environmental Factors

Exposure to pollution or harmful chemicals might increase the chances of developing this condition.
Certain external factors may worsen the inflammation.

Immune System Issues

If the immune system is not working properly, it may mistakenly attack the eye’s choroid layer.
This can lead to long-term damage and vision problems.

Types of Serpiginous Choroiditis

There are two main types of serpiginous choroiditis: geographic and helicoid. Geographic serpiginous choroiditis is characterized by irregularly shaped lesions that spread outward from the optic nerve. Helicoid serpiginous choroiditis, on the other hand, manifests as a swirling or helical pattern of inflammation that progresses from the periphery towards the central vision. Both types can cause vision loss if not promptly diagnosed and treated by an ophthalmologist.

Classic serpiginous choroiditis typically manifests as active, advancing choroiditis with well-defined borders.
Ampiginous choroiditis is a rare variant characterized by a more aggressive and widespread form of choroiditis.
In classic serpiginous choroiditis, lesions often show a characteristic snakelike appearance as they progress.
Ampiginous choroiditis lesions may involve the macula and optic nerve, leading to severe visual impairment.
Both types of serpiginous choroiditis can result in scarring and atrophy of the choroid and

Risk Factors

While the exact cause is unknown, certain risk factors have been identified. These include genetic predisposition, autoimmune disorders, such as rheumatoid arthritis or lupus, and environmental factors like smoking. Additionally, individuals with a history of infections like tuberculosis or toxoplasmosis may be at higher risk for developing serpiginous choroiditis. Early detection and treatment are crucial in preventing complications and preserving vision in patients with this condition.

Genetic predisposition: Having a family history of Serpiginous Choroiditis increases the risk of developing the condition.
Autoimmune disorders: Conditions like rheumatoid arthritis or lupus can elevate the likelihood of Serpiginous Choroiditis.
Age: Older individuals are more prone to developing Serpiginous Choroiditis compared to younger age groups.
Gender: Women may have a higher risk of developing Serpiginous Choroiditis compared to men.
Ethnicity: Some ethnic groups may have a higher susceptibility to Serpiginous Choroiditis than others.

Diagnosis of Serpiginous Choroiditis

Typically, the process involves a thorough eye examination by an ophthalmologist to assess the characteristic lesions in the choroid layer at the back of the eye. Here are the following approaches involved in serpiginous choroiditis diagnosis:

Diagnosis of Serpiginous Choroiditis typically involves a comprehensive eye examination by an ophthalmologist.
Fluorescein angiography may be used to visualize the characteristic lesions in the choroid.
Indocyanine green angiography can help in further delineating the extent of choroidal involvement.
Optical coherence tomography (OCT) may reveal subretinal fluid or retinal pigment epithelial detachments.
Blood tests may be performed to rule out infectious or inflammatory causes.
A thorough medical history and symptom assessment are crucial in the diagnostic process.

Treatment for Serpiginous Choroiditis

Serpiginous choroiditis is a rare but serious eye condition affecting the choroid layer. If left untreated, it can lead to severe vision loss. Proper serpiginous choroiditis treatment is necessary to control inflammation, manage complications, and protect eyesight. Treatment usually involves medications to suppress the immune response and prevent further damage. Here are the treatment options for serpiginous choroiditis

Immunosuppressive Therapy

Corticosteroids: Commonly prescribed to reduce inflammation and ease symptoms.
Immunosuppressants:
- Methotrexate
- Biologic agents (like anti-TNF medicines)
- Given to patients who do not respond well to steroids.

Anti-Inflammatory Medicines

Anti-VEGF Drugs: Help control disease activity and prevent complications like choroidal neovascularization.

Laser & Photodynamic Therapy

Used in severe cases to target inflamed areas and prevent further damage.

Regular Check-ups

Frequent visits to an eye specialist are crucial to monitor progress.
Treatment may be adjusted based on the response to prevent vision loss.
