Iritis

 

an inflammation of the iris of the eye. Since the iris and the ciliary body of the eye are supplied with blood from the same system, an isolated inflammation of the iris is rarely observed; as a rule, iritis is accompanied by inflammation of the ciliary body (see IRIDOCYCLITIS). The term “iritis” is used when inflammation of the iris predominates.

It is to be noted that permanent ocular damage or visual loss can be the consequence of management delay in case of critical acute ophthalmic conditions such as acute glaucoma or severe iritis. Shields [13] stressed that patients suffering persistent or severe eye conditions, especially those involving foreign bodies or corneal abrasions due to high-velocity injuries, should be immediately referred to an ophthalmologist.
However, Ko et al., (1995) observed severe corneal opacity, iritis, conjunctival erythema, edema, and discharge after 13 days, revealing mild skin irritation and severe eye irritation.
This is the first reported case with NFL hemorrhage and thickening and iritis concurrent with papillitis without decreased visual acuity or visual field loss.
Simultaneously frequent iritis during reaction might have induced damage to the iris and later, with due course of time, attachment of the iris to the corneal scar.
A public health expert Dr Wasim Khawaja from Pakistan Institute of Medical Sciences (PIMS) said that the complications of dengue fever are depression, chronic fatigue, pneumonia, bone marrow failure, iritis, orchitis, and variety of neurological complications.
Otras manifestaciones son neuritis, dolor, edema en miembros superiores e inferiores menos intensos que en la reaccion tipo 1, orquitis, iritis, episcleritis y epistaxis (27).
Episodes can last from a few days to 1-2 weeks, and can include migratory nonspecific pain, a rash, abdominal pain, joint pain, chest pain, mouth sores, puffy eyes, and various inflammatory eye symptoms, such as uveitis, iritis, and conjunctivitis.
Any or all of the following symptoms and signs may be associated with ENL, or may occur without ENL, and all are manifestations of type 2 reaction: fever and malaise, nerve pain, periosteal pain, muscle pain, pain and swelling of joints, rhinitis, epistaxis, acute iritis, painful dactylitis, swollen and tender lymph nodes, acute epididymo-orchitis and proteinuria.
Ophthalmologic findings can include uveitis, iritis, vitrial detachment, optic neuritis, and marked vision loss.
However, mobile adult worms trapped in the subconjunctiva or anterior chamber should be removed by eye surgeons to permit precise identification, to prevent posterior uveitis and iritis, and to stop worm migration into the posterior chamber which could cause further eye damage and may require lens removal and vitrectomy for impacted worm extraction.
Other organ involvements are: gastrointestinal (hepatitis, gastritis), renal (glomerulonephritis), pulmonary nodular infiltrates, osseous (periostitis, osteomyelitis, polyarthritis), ophtalmic (optic neuritis, iritis, retinitis), cranial nerve palsies, etc.
Lyons details the nature of syphilitic iritis, its onset and development; he notes that these did not match the timing of Joyce's illness.
