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.
It is often associated with substantial losses in visual fields, pain on moving the globe, and sensitivity to light pressure on the globe. It is often an early sign of multiple sclerosis. [2] Papillitis may have the same appearance as papilledema. However, papillitis may be unilateral, whereas papilledema is almost always bilateral.
Pain, visual loss, relapse, and steroid response are typical of CRION. [1] [3] Ocular pain is typical, although there are some cases with no reported pain. [3] Bilateral severe visual loss (simultaneous or sequential) usually occurs, but there are reports of unilateral visual loss. [3] Patients can have an associated relative afferent pupillary ...
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Major symptoms are sudden loss of vision (partial or complete), sudden blurred or "foggy" vision, and; pain on movement of the affected eye. [4] [5] [2]Many patients with optic neuritis may lose some of their color vision in the affected eye (especially red), with colors appearing subtly washed out compared to the other eye.
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.
The main symptom is loss of vision, with colors appearing subtly washed out in the affected eye. A pale disc is characteristic of long-standing optic neuropathy. In many cases, only one eye is affected and a person may not be aware of the loss of color vision until the examiner asks them to cover the healthy eye.
LHON, as the name suggests, is an inherited mutation that results in acute or subacute vision loss, displays incomplete penetrance and predominantly affects young males. Onset is usually between the 2nd and 4th decade of life, and usually presents with rapid vision loss in one eye followed by involvement of the second eye (usually within months).
