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. [6] Hannibal's sight was lost in his right eye in 217 BC by what was likely ophthalmia. He lost ...
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 .
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 ...

Adenoviral keratoconjunctivitis, also known as epidemic keratoconjunctivitis, is a contagious eye infection, a type of adenovirus disease caused by adenoviruses. [1] It typically presents as a conjunctivitis with a sudden onset of a painful red eye, watery discharge and feeling that something is in the eye. [3]
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.
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]
