When most people think of tuberculosis (TB), they imagine a disease affecting the lungs. But here’s a surprising fact — TB can also affect your eyes. This condition is called Ocular Tuberculosis, and if it’s not treated on time, it may lead to serious and even permanent vision problems.
As an Eye specialist in Delhi, I’ve seen many patients shocked to hear that TB can happen in the eyes. The good news? If treated early, there’s a strong chance that your eyesight can be protected. Let’s dive into what ocular TB is, how it happens, and most importantly, how it can be treated.
What is Ocular Tuberculosis?
Ocular Tuberculosis is an infection of the eye caused by the same bacteria that cause lung TB — Mycobacterium tuberculosis. It can affect different parts of the eye, such as the retina, uvea, conjunctiva, or optic nerve.
Sometimes, it spreads from the lungs to the eyes through the blood. In other cases, it only affects the eye without any lung involvement.
Who is at Risk? (Risk Factors)
Anyone can develop ocular TB, but certain factors make it more likely:
- Weakened immune system– People with poor immunity are more vulnerable.
- History of TB exposure– Living with or being in close contact with someone who has TB.
- Past TB infection– Even if you had TB many years ago, the bacteria can stay inactive in your body and reactivate later.
- Poor living conditions– Overcrowded areas with limited ventilation increase risk.
- Chronic illnesses– Diabetes or HIV can make the body more susceptible.
What Causes Ocular Tuberculosis?
The root cause is the TB bacteria (Mycobacterium tuberculosis). It can:
- Spread from the lungs– The bacteria travel via the bloodstream.
- Directly infects the eye– Rare but possible through injury or surgery.
- Reactivate from dormant bacteria– TB can “sleep” in the body for years and wake up when immunity drops.
Symptoms – How Does Ocular TB Feel?
Symptoms can vary depending on which part of the eye is infected. Here are some common ones:
- Blurred or reduced vision
- Redness of the eye
- Eye pain
- Sensitivity to light
- Floating spots or shadows in vision (floaters)
- Swelling of the eyelids
- Watery eyes
- Unexplained eye inflammation that keeps coming back
These symptoms can mimic other eye diseases, which is why you need an eye doctor to confirm the cause.
Signs Your Eye Specialist Looks For
When you visit an Eye hospital in Delhi for an eye test, your doctor might notice:
- Swelling in the back of the eye (retina or choroid)
- Yellowish spots in the retina (granulomas)
- Signs of inflammation inside the eye (uveitis)
- Optic nerve swelling
- Persistent conjunctivitis that does not respond to routine treatment
How is Ocular Tuberculosis Diagnosed?
Your eye specialist will start with a detailed eye examination and then may suggest:
- Eye imaging tests– OCT (Optical Coherence Tomography) or Fundus Photography
- Blood tests– TB Gold or Mantoux test to detect TB infection
- Chest X-ray or CT scan– To check for lung TB
- Eye fluid tests– In rare cases, to directly detect TB bacteria
Treatment Options for Ocular Tuberculosis
The treatment focuses on two things: killing the TB bacteria and controlling inflammation.
- Anti-Tuberculosis Therapy (ATT)
- A combination of medicines is given for 6–9 months.
- These medicines are prescribed in consultation with a chest physician.
- Steroid Eye Drops or Tablets
- To reduce eye inflammation.
- Used carefully under a doctor’s supervision to avoid side effects.
- Regular Eye Checkups
- To monitor recovery and prevent complications.
- Treatment of Related Eye Problems
- Sometimes, laser therapy or minor surgery may be necessary to address complications.
When to See an Eye Doctor Immediately
You should seek urgent help if you notice:
- Sudden vision loss
- Severe eye pain
- Light flashes or sudden floaters
- Persistent redness or swelling
- TB history with new eye symptoms
Possible Complications if Left Untreated
Ocular TB can be dangerous if ignored. Complications may include:
- Permanent vision loss
- Glaucoma (eye pressure damage)
- Retinal detachment
- Optic nerve damage
- Chronic inflammation leading to scarring
