Adie syndrome presents with three hallmark symptoms, namely at least one abnormally dilated pupil which does not constrict in response to light, loss of deep tendon reflexes, and abnormalities of sweating. [1] Other signs may include hyperopia due to accommodative paresis, photophobia and difficulty reading. [3]
Uveitis may be an immune response to fight an infection caused by an organism in the eye. They are less common than non-infectious causes and require antimicrobial/ viral/ parasitic treatment in addition to inflammatory control. Infectious causes in order of global burden include: Subretinal abscess in tubercular posterior uveitis. bartonellosis
The mechanism by which the bacteria causes symptoms of blepharitis is not fully understood and may include direct irritation of bacterial toxins and/or enhanced cell-mediated immunity to S. aureus. Staphylococcal blepharitis is caused by an infection of the anterior portion of the eyelid by Staphylococcal bacteria. [14]
There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
The interior of the eye lacks lymph vessels but is highly vascularized, and many immune cells reside in the uvea, including mostly macrophages, dendritic cells, and mast cells. [1] These cells fight off intraocular infections, and intraocular inflammation can manifest as uveitis (including iritis) or retinitis. The cornea of the eye is ...
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.

Non-physiological causes of mydriasis include disease, trauma, or the use of certain types of drug. It may also be of unknown cause. Normally, as part of the pupillary light reflex, the pupil dilates in the dark and constricts in the light to respectively improve vividity at night and to protect the retina from
