Nodular Scleritis: Causes, Symptoms And Treatment

Nodular scleritis is a condition that affects the white outer coating of the eye known as the sclera. It is characterized by the development of nodules or lumps on the sclera, which can cause pain, redness, and inflammation.

The exact cause of nodular scleritis is not fully understood, but it is believed to be linked to underlying autoimmune diseases such as rheumatoid arthritis or systemic lupus erythematosus. In some cases, infections or trauma to the eye may also contribute to the development of nodular scleritis.

Understanding the underlying cause of nodular scleritis is important for effective management and treatment. If you experience any symptoms related to eye pain or redness, it is essential to

What Are the Symptoms of Nodular Scleritis

Symptoms may include severe eye pain, redness, tearing, sensitivity to light, and blurred vision. Patients with nodular scleritis often experience a visible raised area on the sclera, which can be tender to touch.

In some cases, the condition may also be associated with systemic diseases like rheumatoid arthritis. If you are experiencing these symptoms, it is essential to seek medical attention promptly to receive appropriate treatment and prevent potential complications.

Redness and inflammation in the eye that is often painful and may be accompanied by blurred vision.
Sensitivity to light, causing discomfort when exposed to bright light sources such as sunlight or artificial lighting.
Tenderness and swelling around the affected eye, which may be noticeable to the individual or their healthcare provider.
Discharge or tearing from the eye, which can be a bothersome symptom and may indicate underlying inflammation.
Changes in vision, such as seeing halos around lights or experiencing difficulty focusing, which can impact daily activities and quality of life.

Causes of Nodular Scleritis

Autoimmune conditions such as rheumatoid arthritis, systemic lupus erythematosus, and granulomatosis with polyangiitis are common triggers for nodular scleritis. Infections, including herpes zoster and tuberculosis, can also lead to this condition.

Additionally, trauma or injury to the eye, exposure to irritants, or underlying systemic diseases may contribute to the development of nodular scleritis. Understanding these potential causes is crucial for accurate diagnosis and appropriate management of this painful and potentially sight-threatening condition.

Autoimmune disorders, such as rheumatoid arthritis, can trigger nodular scleritis, causing inflammation in the eye's sclera.
Infections, like herpes zoster virus or tuberculosis, may lead to nodular scleritis by affecting the eye's tissues.
Systemic inflammatory conditions, including sarcoidosis or granulomatosis with polyangiitis, can contribute to the development of nodular scleritis.
Trauma or injury to the eye can result in nodular scleritis, leading to localized inflammation and nodules on the sclera.
Underlying medical conditions like gout or syphilis can be associated with nodular scleritis, impacting the eye's scleral tissue.

Types of Nodular Scleritis

Anterior nodular scleritis typically presents with a raised, localized area near the limbus, causing severe pain and redness. Posterior nodular scleritis affects the posterior segment of the eye, leading to blurry vision and discomfort. Necrotizing scleritis with inflammation may result in tissue damage and thinning of the sclera.

Diffuse anterior nodular scleritis involves multiple nodules across the anterior sclera, causing significant inflammation and discomfort. Understanding these variations is crucial for proper diagnosis and management of nodular scleritis.

Types of Nodular Scleritis:

Diffuse Anterior Scleritis: This type involves inflammation across a wide area of the sclera, causing redness, pain, and tenderness.
Nodular Anterior Scleritis: Characterized by localized nodules on the sclera, leading to a raised, firm area that can be quite painful.
Necrotizing Scleritis: A severe form where tissue death (necrosis) occurs in the sclera, often associated with serious complications and vision loss.
Posterior Scleritis: Involves inflammation at the back of the eye, leading to symptoms such as eye pain, blurred vision, and sensitivity to light.

Risk Factors

Nodular scleritis is a serious eye condition with various risk factors that may contribute to its development. These risk factors include autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus, infections like herpes zoster, trauma or injury to the eye, and certain medications such as bisphosphonates.

Additionally, individuals with a history of smoking or those exposed to environmental factors like UV radiation may also be at an increased risk of developing nodular scleritis. Proper management and early detection are crucial in addressing this condition and preventing potential complications.

Having an autoimmune disease, such as rheumatoid arthritis, increases the risk of developing nodular scleritis.
Individuals with a history of eye trauma or injury are at higher risk of developing nodular scleritis.
Smoking is a significant risk factor for nodular scleritis and can worsen the condition if already present.
Certain infections, such as herpes zoster, can increase the likelihood of developing nodular scleritis.
Women are more likely than men to develop nodular scleritis, making gender a potential risk factor.

Diagnosis of Nodular Scleritis

Symptoms such as eye pain, redness, and vision changes are assessed, along with the presence of nodules on the sclera. Additional tests like blood work, imaging studies, or a biopsy may be recommended to rule out underlying causes or associated conditions.

Ophthalmic evaluation, including slit-lamp examination and ocular imaging, helps in confirming the diagnosis and determining the severity of the condition. A multidisciplinary approach involving rheumatologists or other specialists may be necessary for comprehensive management and treatment planning.

Diagnosis of nodular scleritis typically involves a comprehensive eye examination by an ophthalmologist.
Ocular imaging, such as ultrasound or optical coherence tomography, may be used to assess the severity of inflammation.
Blood tests can help identify underlying systemic conditions associated with nodular scleritis.
Biopsy of the scleral nodule may be performed to confirm the diagnosis and rule out other causes.
A thorough medical history review is crucial to understand the patient's symptoms and potential triggers for scleritis.

Treatment for Nodular Scleritis

Treatment for Nodular Scleritis aims to reduce inflammation and relieve symptoms. Nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids may be prescribed to decrease inflammation and pain. In severe cases, immunosuppressive medications like methotrexate or biologics may be necessary to manage the condition. Additionally, artificial tears or lubricating eye drops can help with dryness and discomfort. In some instances, surgery may be required to address complications such as scleral thinning or perforation. It is important to consult with an ophthalmologist for a personalized treatment plan tailored to individual needs and the severity of the condition.

Nodular scleritis, a severe form of scleritis characterized by painful inflammation and the presence of nodules on the sclera, typically requires aggressive treatment.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to help reduce pain and inflammation associated with nodular scleritis.
Corticosteroids, either in the form of eye drops, oral medications, or injections around the eye, are often used to control inflammation in nodular scleritis.
Immunosuppressive drugs, such as methotrexate or cyclosporine, may be recommended in cases of severe or recurrent nodular scleritis to help suppress the immune response.
