Introduction:

In India, a country with a rich cultural heritage and diverse population, the prevalence of uveitis is a significant concern. Uveitis refers to the inflammation of the uvea, which is the middle layer of the eye responsible for providing blood supply and nourishment to the retina. This condition can be debilitating and may lead to vision loss if left untreated. In this article, we will explore the signs, symptoms, classification, causes, risk factors, types, diagnostic tests, treatments, complications, and prevention techniques associated with uveitis, with a focus on India.

Signs and Symptoms:

Uveitis can manifest with a variety of signs and symptoms, depending on the specific type and severity of inflammation. Common indicators include eye redness, pain, blurred vision, sensitivity to light, floaters (spots or specks that float in the visual field), and decreased visual acuity. Some individuals may also experience headaches, eye floaters, and a feeling of “grittiness” in the eye.

What is Uveitis? :

Uveitis is a broad term encompassing a group of eye conditions characterized by inflammation of the uvea. The uvea consists of the iris, ciliary body, and choroid. Uveitis can affect one or both eyes and may be acute (short-term) or chronic (long-lasting). It is crucial to seek prompt medical attention in case of any suspected symptoms to prevent potential complications and vision loss.

Classification of Uveitis:

Uveitis can be classified based on the affected part of the uvea, duration, and underlying cause. The primary classifications are:

• Anterior Uveitis (Iritis): Inflammation predominantly involving the front part of the uvea, including the iris and ciliary body.

• Intermediate Uveitis (Cyclitis): Inflammation affecting the middle part of the uvea, including the ciliary body.

• Posterior Uveitis (Choroiditis): Inflammation affecting the back part of the uvea, including the choroid.

• Panuveitis: Inflammation involving all layers of the uvea.

 Causes and Triggers:

Uveitis can have various causes and triggers, including infections (such as tuberculosis or viral infections), autoimmune disorders (such as rheumatoid arthritis or lupus), trauma or injury to the eye, certain medications, and sometimes the cause remains unknown (idiopathic uveitis). In India, infectious causes such as tuberculosis, toxoplasmosis, and dengue fever are relatively more prevalent, emphasizing the importance of accurate diagnosis and appropriate treatment.

Risk Factors:

Several risk factors may increase the likelihood of developing uveitis. These include:

• Autoimmune Disorders: Conditions like rheumatoid arthritis, ankylosing spondylitis, or sarcoidosis.

• Infections: Tuberculosis, herpes simplex, HIV/AIDS, or toxoplasmosis.

• Eye Trauma: Previous eye injuries or surgeries.

• Genetic Predisposition: Certain genetic factors may increase susceptibility to uveitis.

• Age: Uveitis can occur at any age, but it most commonly affects individuals between 20 and 60 years old.

• Ethnicity: Certain ethnic groups may have a higher risk of developing uveitis.

Types of Uveitis:

 a. Anterior Uveitis (Iritis):

• Most common type.

• Presents with eye redness, pain, light sensitivity, and blurred vision.

• May be associated with autoimmune disorders or infections.

b. Intermediate Uveitis (Cyclitis):

• Inflammation primarily affects the vitreous (gel-like substance inside the eye).

• Symptoms include floaters, blurred vision, and eye pain.

• Associated with conditions like multiple sclerosis or sarcoidosis.

c. Posterior Uveitis (Choroiditis):

• Involves inflammation of the choroid layer at the back of the eye.

• Presents with decreased vision, floaters, and visual disturbances.

• Infections, such as toxoplasmosis or viral retinitis, can cause this type of uveitis.

d. Panuveitis: 

• Affects all layers of the uvea.

• Symptoms include severe eye pain, redness, blurred vision, and sensitivity to light.

• Can be associated with systemic diseases like Behçet’s disease or Vogt-Koyanagi-Harada syndrome.

Diagnostic Tests and Treatments:

Diagnosing uveitis requires a comprehensive eye examination, including a detailed medical history and various diagnostic tests. The tests commonly used include:

1. Visual Acuity Test: Measures how well an individual can see at various distances.

2. Slit-lamp Examination: Allows the doctor to examine the structures of the eye using a specialized microscope.

3. Fundoscopy: Examination of the retina and optic nerve to assess for any signs of inflammation or damage.

4. Optical Coherence Tomography (OCT): Provides detailed images of the retina, helping in the evaluation of the extent of inflammation.

5. Blood Tests: Aid in identifying underlying infections, autoimmune disorders, or systemic diseases.

6. Aqueous or Vitreous Tap: Collecting a small sample of fluid from the eye for laboratory analysis if an infection is suspected.

 Treatment for uveitis involves addressing the underlying cause, relieving inflammation, and preventing complications. It may include:

• Topical or oral corticosteroids to reduce inflammation.

• Immunosuppressive medications in cases of severe or chronic uveitis.

• Antiviral, antibiotic, or antifungal medications if an infection is present.

• Biologic therapies for certain types of uveitis.

• Intravitreal injections for localized treatment.

Complications of Uveitis:

If left untreated or poorly managed, uveitis can lead to severe complications, such as cataracts, glaucoma, retinal detachment, macular edema, and permanent vision loss. Regular follow-up appointments with an ophthalmologist are crucial to monitor the condition and address any emerging complications promptly.

Prevention Techniques:

While some cases of uveitis cannot be prevented, certain measures can help reduce the risk and manage the condition effectively: 

• Promptly treat underlying infections or systemic diseases.

• Protect the eyes from trauma by using appropriate safety measures.

• Seek regular eye examinations to detect uveitis at an early stage.

• Follow prescribed treatment plans and medications as directed by healthcare professionals.

• Maintain overall good health and manage any pre-existing autoimmune conditions

Uveitis, a group of inflammatory diseases affecting the uvea (middle layer) of the eye, can lead to severe visual impairment if not diagnosed and managed properly.
