Intermediate Uveitis

Intermediate uveitis is when the middle part of the eye (the vitreous gel and the pars plana just behind the iris) becomes inflamed. This means the tissues in that area swell up because of cells from your immune system. People often call it “pars planitis” when they see white clumps (“snowballs”) or deposits (“snowbanking”) on the edge of the retina. In intermediate uveitis, there is no inflammation in the front (iris) or back (retina/choroid) of the eye—just in the middle layer where the vitreous sits Taylor & Francis Online.

Intermediate uveitis is inflammation primarily involving the vitreous—the clear, gel-like substance filling the back of the eye—and the peripheral retina. In simple terms, immune cells infiltrate and irritate the middle part of the eye, causing floaters, blurred vision, and, if left untreated, sight-threatening complications like cystoid macular edema (CME) Wikipedia. It may occur on its own or herald systemic conditions such as multiple sclerosis or sarcoidosis Wikipedia. The defining hallmarks are “snowballs” (clumps of inflammatory cells in the vitreous) and “snowbanking” (whitish exudates along the pars plana) NCBI.

Anatomic Classification & Types

According to the Standardization of Uveitis Nomenclature (SUN) working group, uveitis is divided by where the inflammation happens. Intermediate uveitis involves mainly the vitreous and pars plana and includes three subtypes:

  • Pars Planitis: Inflammation at the flat part of the ciliary body, often with “snowbanking” on the pars plana.

  • Posterior Cyclitis: Inflammation primarily of the back part of the ciliary body, sometimes extending into the vitreous.

  • Hyalitis: Inflammation limited mostly to the vitreous gel itself.
    Together, these three patterns make up intermediate uveitis PMCMD Searchlight.


Types of Intermediate Uveitis

1. Pars Planitis
Pars planitis is a type of intermediate uveitis where white inflammatory deposits form on the pars plana, the flat part of the ciliary body behind the iris. These deposits look like snowbanks, and you may also see floating white clumps called snowballs. This form often affects young adults and children and can recur over time MD Searchlight.

2. Posterior Cyclitis
Posterior cyclitis means inflammation is deeper in the eye, at the back of the ciliary body. In this type, the vitreous may have scattered inflammatory cells, and the nearby retina can show mild swelling or blood vessel changes. Patients can have floaters and blurred vision when the cells leak into the gel Orpha.

3. Hyalitis
Hyalitis refers to inflammation confined mostly to the vitreous gel, without much visible change on the pars plana. The vitreous becomes hazy or cloudy, causing vision to be fuzzy. This type may not show snowbanking but still leads to floaters and decreased vision due to the cloudy gel American Academy of Ophthalmology.

4. Systemic disease–associated
This type occurs in patients with conditions like multiple sclerosis or sarcoidosis. The underlying disease triggers immune cells to inflame the vitreous, so treating the systemic disorder helps control eye inflammation ScienceDirect.

5. Infectious intermediate uveitis
Infections such as tuberculosis, Lyme disease, or syphilis can inflame the vitreous and peripheral retina. Identifying and treating the infection is key to preventing recurrent inflammation Verywell Health.

6. Masquerade syndrome
Rarely, cancers (e.g., intraocular lymphoma) mimic intermediate uveitis. In these cases, malignant cells infiltrate the vitreous, requiring biopsy or imaging to distinguish from true inflammation PMC.


Causes of Intermediate Uveitis

Many times, doctors cannot find a clear reason for intermediate uveitis (idiopathic). But when a cause is known, it often links to infections, autoimmune disorders, or systemic illnesses. Below are 20 possible causes, each explained in very simple terms:

  1. Idiopathic (Unknown Cause)
    Most patients (50–70%) have no clear trigger. Doctors call this “idiopathic.” It means cells leak into the vitreous for reasons we can’t see on tests Cleveland Clinic.

  2. Multiple Sclerosis
    In some people with MS, the immune system attacks both nerves and eye tissues. About 15% of intermediate uveitis cases link to MS, causing inflammation in the vitreous PMC.

  3. Sarcoidosis
    Sarcoidosis makes small clumps (granulomas) in organs, including the eye. Roughly 25% of people with sarcoidosis develop intermediate uveitis when these clumps form in the vitreous or pars plana EyeWiki.

  4. Lyme Disease
    Caused by a tick bite carrying Borrelia bacteria, Lyme disease can trigger inflammation in the eye weeks or months after the bite, leading to floaters and blurred vision PMC.

  5. Tuberculosis (TB)
    TB bacteria can spread from the lungs to the eye and cause scattered inflammation in the vitreous gel. Doctors look for TB by doing chest X-rays and blood tests PMC.

  6. Syphilis
    The bacteria that cause syphilis can infect the eye, leading to white blood cells in the vitreous. Tests like VDRL or FTA-ABS help find this infection American Academy of Ophthalmology.

  7. Toxoplasmosis
    A tiny parasite (Toxoplasma gondii) from undercooked meat or cat feces can inflame retinal tissue and vitreous, causing floaters and blurred spots.

  8. Toxocariasis
    Roundworm larvae from pets can enter the eye, causing localized inflammation near the pars plana and in the vitreous.

  9. Cat-Scratch Disease
    Bartonella henselae from a cat scratch can inflame eye tissues, including the vitreous, leading to intermediate uveitis symptoms.

  10. HTLV-1 Infection
    Human T-lymphotropic virus type 1 can infect immune cells, sometimes causing ocular inflammation in the vitreous.

  11. Epstein-Barr Virus (EBV)
    EBV, the virus that causes mononucleosis, can rarely trigger intermediate uveitis by attacking eye tissues.

  12. Juvenile Idiopathic Arthritis (JIA)
    In children with JIA, the immune system attacks joints and can also attack eye tissues, causing intermediate uveitis without clear pain Cleveland Clinic.

  13. Behçet’s Disease
    An autoimmune disease that inflames blood vessels can affect the uvea, causing repeated episodes of intermediate uveitis.

  14. Wegener’s Granulomatosis
    Now called granulomatosis with polyangiitis, this disease damages small blood vessels and can inflame the vitreous.

  15. Inflammatory Bowel Disease (IBD)
    Ulcerative colitis or Crohn’s disease can sometimes cause immune cells to attack the eye, including intermediate structures.

  16. Leukemia/Lymphoma
    Cancer of blood cells can sometimes involve the eye, with malignant cells infiltrating the vitreous.

  17. Intraocular Lymphoma
    A type of eye cancer that often looks like chronic uveitis, with cells in the vitreous.

  18. Local Eye Injury
    A blunt injury or surgery can trigger inflammation deep in the eye, including the vitreous.

  19. Medication-Induced
    Some drugs (like rifabutin or cidofovir) can cause uveitis as a side effect, inflaming the vitreous.

  20. Viral Infections (Herpes Viruses)
    Herpes simplex or varicella-zoster viruses can spread to the vitreous, causing intermediate inflammation.

Symptoms of Intermediate Uveitis

Intermediate uveitis often comes on slowly and may last a long time. Here are 15 common symptoms, each explained in plain English:

  1. Floaters
    Little dots or threads that seem to drift in your vision. They are clumps of white blood cells in the vitreous Moorfields Eye Hospital.

  2. Blurred Vision
    Vision becomes fuzzy because the vitreous turns cloudy from inflammation Moorfields Eye Hospital.

  3. Mild Eye Redness
    Unlike front-eye uveitis, the redness is often low-grade and may not be very noticeable Moorfields Eye Hospital.

  4. Eye Pain
    A dull ache rather than sharp pain, felt deep in the eye.

  5. Photophobia (Light Sensitivity)
    Bright lights seem too strong or uncomfortable, because the inflamed tissues react to light.

  6. Decreased Night Vision
    It becomes harder to see in dim light, since inflammation scatters light inside the eye.

  7. Vitreous Haze
    A grayish film over what you see, caused by proteins leaking into the vitreous.

  8. Metamorphopsia
    Straight lines appear wavy, as inflammation near the retina alters light paths.

  14. Reduced Depth Perception
    Judging distances becomes harder, since light scattering blurs fine details.

  15. Intermittent Symptoms
    Symptoms may improve or worsen over weeks to months, as inflammation flares or calms.


Diagnostic Tests for Intermediate Uveitis

To find intermediate uveitis and its cause, eye doctors use a mix of physical checks, manual procedures, lab tests, electrodiagnostic measures, and imaging. Below are 20 key tests, grouped by type, each explained in very simple English:

A. Physical Exam

  1. Visual Acuity Test

  3. Intraocular Pressure (IOP) Measurement
    Checks fluid pressure inside your eye using a small puff of air or a gentle probe. Uveitis can lower or raise IOP.

  4. Fundus Examination
    With special lenses, the doctor looks at the back of your eye (retina and vitreous) to spot cells or snowbanking.

B. Manual Procedures

  1. Gonioscopy
    Uses a mirror lens on the eye to check the drainage angle; inflammation can narrow angles.

  2. Indirect Ophthalmoscopy with Scleral Depression
