Symptoms include eye pain, eye redness, floaters and blurred vision, and ophthalmic examination may show dilated ciliary blood vessels and the presence of cells in the anterior chamber. Uveitis may arise spontaneously, have a genetic component, or be associated with an autoimmune disease or infection .
Eratosthenes, who among other things was a Greek geographer and mathematician, contracted ophthalmia as he aged, becoming blind around 195 BC, depressing him and causing him to voluntarily starve himself to death. He died in 194 BC at the age of 82. [7] Hannibal's sight was lost in his right eye in 217 BC by what was likely ophthalmia. He lost ...
Endophthalmitis requires immediate medical attention to ensure the condition is diagnosed as soon as possible and treatment is started in order to reduce the risk of the person losing vision in the eye. [2] Treatment options depend on the cause and whether the condition is caused by an endogenous or exogenous mechanism.
The infection usually begins in one eye but may spread easily to the other eye. [ citation needed ] Viral conjunctivitis manifests as a fine, diffuse pinkness of the conjunctiva which may be mistaken for iritis , but corroborative signs on microscopy , particularly numerous lymphoid follicles on the tarsal conjunctiva, and sometimes a punctate ...
In many cases the cause of panuveitis is unknown. [5] Possible causes include exogenous or endogenous infection, injury, or an autoimmune disease. Endogenous infections caused by syphilis, tuberculosis, mumps, smallpox, influenza, toxoplasmosis, lupus, sarcoidosis, and immune-related inflammations such as Behcet syndrome or Vogt–Koyanagi–Harada disease causes panuveitis.
Long-term untreated blepharitis can lead to eyelid scarring, excess tearing, difficulty wearing contact lenses, development of a stye (an infection near the base of the eyelashes, resulting in a painful lump on the edge of the eyelid) or a chalazion (a blockage/bacteria infection in a small oil gland at the margin of the eyelid, just behind the ...
Some infections may scar the cornea, thereby limiting vision. Others may result in perforation of the cornea, endophthalmitis (an infection inside the eye), or even loss of the eye. With proper medical attention, infections can usually be successfully treated without long-term visual loss. [citation needed]
Keratoconjunctivitis is a term used to describe inflammation of both the cornea (the clear, front part of the eye) and the conjunctiva (the thin, transparent membrane covering the white part of the eye and lining the inside of the eyelids). This condition can have various causes, and its presentation may vary depending on the underlying factors.
