The most common eye signs of tuberculosis (TB) include blurred vision and light sensitivity.
TB can affect the eyes, although it's less common than pulmonary (lung) TB. When it does, it can manifest in several ways. Because symptoms can be subtle or mimic other conditions, diagnosis can be challenging.
Here's a more detailed breakdown of potential eye signs associated with TB:
- Blurred Vision: This is a frequent complaint and can stem from inflammation within the eye.
- Light Sensitivity (Photophobia): Increased sensitivity to light can be another indicator.
- Redness of the Eye: Inflammation may cause the eye to appear red or bloodshot.
- Floaters: Patients may see spots or specks that drift across their field of vision.
- Flashes: Some individuals report seeing flashes of light.
- Headache: Eye involvement in TB can sometimes be accompanied by headaches.
It's important to note that some individuals with ocular TB might be asymptomatic, meaning they experience no noticeable symptoms. Others may have symptoms affecting the eyes as their only complaint.
The specific eye conditions linked to TB include:
- Uveitis: Inflammation of the uvea, the middle layer of the eye. This is a common manifestation.
- Choroiditis: Inflammation of the choroid, the layer beneath the retina.
- Retinal vasculitis: Inflammation of the blood vessels of the retina.
- Optic neuritis: Inflammation of the optic nerve, which can lead to vision loss.
- Phlyctenular keratoconjunctivitis: Small nodules form on the cornea or conjunctiva.
If you experience any of these symptoms, particularly if you have a history of TB exposure or infection, it is crucial to consult with a healthcare professional and an ophthalmologist for proper evaluation and diagnosis. Early detection and treatment are essential to prevent vision loss and other complications.
