The case of a 31-year-old man who presented to the emergency department with iritis from intranasal cocaine use is described. This was the second episode of iritis in this patient after casual cocaine use. The differential diagnosis of iritis and a proposed pathophysiologic mechanism are discussed.
From November 1981 to early March 1982, an outbreak of scleritis and/or iritis occurred among patients treated with a Nipro brand NAC series cellulose acetate capillary dialyzer. The rate of incidence with dialyzers produced in 1982 was significantly higher than that with dialyzers produced in 1981. An extract obtained from the dialyzers caused iritis in rabbits after its infusion into an auricula vein. Glycerol, acetylated carbohydrate (AC) derivatives, urethane derivatives, and polypropyleneglycol were found in the extract. AC derivatives caused iritis in rabbits, whereas they caused hyperemia of the bulbar conjunctiva in dogs. The AC derivatives contained xylose and glucose units in a ratio of 1.6-2.3:1. The amounts of AC derivatives were significantly larger in the extracts from 1982 than from 1981 devices. Moreover, another brand, but the same type, of dialyzer, the Cordis Dow 4000, contained a slight amount of them. These facts show that AC derivatives derived from hemicellulose played a primary role in the outbreak.
Evidence has been sought for a genetically determined predisposition among children with juvenile rheumatoid arthritis (JRA) who are also at particular risk for the development of inflammatory eye disease.45 unrelated Caucasian patients (41 female) with early-onset pauciarticular JRA were human leukocyte antigen (HLA) types. 28 of the study group were found to be HLA-DRw5 compared with 16 of 84 controls (X(2), 24.3, P = <0.001). 9 patients were HLA-DRw8 compared with 4 of 84 controls (X(2), 7.51, P = <0.01). Iritis developed in 24 of the 45 children studied, 17 of whom were typed as HLA-DRw5 when compared to controls (X(2), 26.76, P = <0.001) and 6 with iritis typed as HLA-DRw8 (X(2), 9.10, P = <0.01). Antinuclear antibody was found in the serum of 17 of the 28 patients typing as HLA-DRw5 compared with 4 of the 17 who did not have this antigen (X(2), 5.88, P = <0.02). No such association was seen in patients with HLA-DRw8. In a study of linked genes, a delta value of 0.090 was found for HLA-DRw5 with HLA-B12, of 0.070 for DRw5 with HLA-Cw4, and a value of 0.050 for DRw5 and HLA-Bw35. This suggests a linkage disequilibrium between HLA-DRw5 and these two B series alleles, a conclusion which was supported by haplotype analysis in families of 11 of the disease probands. HLA-DRw5 has not previously been reported to be increased in any rheumatic disease group. It is proposed that HLA-DRw5 is a genetic marker defining those at risk for early-onset pauciarticular JRA with iritis.
A prospective study that included 82 consecutive children seen over 2 years by five pediatricians was undertaken to determine the incidence of iritis in children with chickenpox. Twenty-one (25%) children without pox on their lids were found to have iritis. Follow-up of children with objective evidence of iritis revealed no long-term sequelae.
A patient with preexisting inactive ankylosing spondylitis experienced a recurrence of back pain and his first episode of acute peripheral arthritis and iritis after a second course of treatment with BCG for bladder cancer. The occurrence of iritis after BCG therapy has not been reported. The recurrence of spondyloarthropathy and the new appearance of iritis may have been part of a generalized enhancement of immunological reactivity produced by the BCG.
OBJECTIVE: We describe a patient with primary Sjögren's syndrome who developed severe, acute, anterior uveitis (iritis), an uncommon complication in this setting. METHODS: We present the case report of the clinical findings, course, treatment, and resolution of the acute uveitis. Titers of anti-SS-A/Ro and anti-SS-B/La antibodies were assessed (by immunodiffusion), as were fluorescent antinuclear antibodies (on HEp-2 cells) and cryoglobulins. RESULTS: Initial treatment with topical steroids, oral prednisone (20 mg/day), and oral methotrexate was unsuccessful. The iritis resolved after combined treatment with intravenous cyclophosphamide (1,500 mg/month), high-dose prednisone (60 mg/day), and cyclosporine (5 mg/kg/day). CONCLUSION: An uncommon, severe complication of primary Sjögren's syndrome is acute uveitis. Combination immunosuppressive therapy may be needed to control this condition.
The iris-claw intraocular lens (IOL) was recently approved by the U.S. Food and Drug Administration for the correction of refractive disorders. Previous reports are not uniform regarding its potential to induce inflammatory reaction. We report the case of a young healthy patient who experienced persistent and intolerable iritis after implantation of an iris-claw IOL. The iritis was resolved only after explantation of the IOL.
PURPOSE: Topical metipranolol therapy for primary open-angle glaucoma has been associated with anterior granulomatous uveitis in the United Kingdom. We studied granulomatous uveitis reactions to topical metipranolol 0.3% therapy for primary open-angle glaucoma in two patients in the United States. METHODS: Two patients, aged 71 and 81 years, were given topical metipranolol 0.3% therapy for primary open-angle glaucoma. RESULTS: Both developed granulomatous uveitis. The iritis was associated with an increase in intraocular pressure in both patients and resolved on discontinuation of the drug. One patient was inadvertently rechallenged with metipranolol, and the iritis recurred. CONCLUSIONS: Topical metipranolol 0.3% therapy may be associated with the development of granulomatous uveitis and a paradoxical increase in intraocular pressure.
PURPOSE: To study the expression of stress-response proteins in the inflamed iris of rats with experimental autoimmune encephalomyelitis (EAE). METHODS: EAE was induced in Lewis rats by immunization with homogenized spinal cord of the guinea pig emulsified in complete Freund's adjuvant (CFA) (group EAE). Control rats included those immunized with only CFA (group CFA) and those that were untreated (group Normal). Immunohistochemical study for the localization of stress-response protein (srp) 27, srp 60, srp 72, ubiquitin, and alphaB-crystallin was performed. RESULTS: All rats in group EAE developed iritis, whereas none of the rats in group CFA and group Normal developed iritis. No expression of ubiquitin, alphaB-crystallin, srp 27, srp 60, or srp 72 was seen in the epithelium of the iris in group CFA rats. In the eyes of rats in group EAE, srp 60 was expressed in the epithelium of the iris in 20 of 22 (90.9%), ubiquitin in 4 of 22 (18.2%), and alphaB-crystallin in 3 of 22 (13.6%). In the group Normal rats, only ubiquitin was expressed in the epithelium of the iris in 1 of 6 (16.7%) eyes examined. CONCLUSIONS: These results suggest that srp 60 may be a potential uveitogenic antigen in the iris in EAE.
Eleven family members over four generations have had granulomatous disease of the skin, eyes, and joints. Ten have had arthritis; two had skin, eye, and joint involvement; one had skin and joint disease, and one had iritis only. The disease is transmitted as an autosomal dominant trait and is not associated with HLA-B27. The disease resembles sarcoidosis in some ways but not in others, and is probably a new syndrome. The major long-term problems are iritis and joint contractures.
We report a patient with broad anterior synechias and corneal endothelial damage. The patient had chronic iritis and cataracts secondary to chronic iritis in both eyes. Because the right eye had broad anterior synechias and severe corneal endothelial damage, extracapsular cataract extraction and intraocular lens implantation were performed through the basal iris. Good postoperative visual acuity was obtained. The cornea showed little trauma from the surgery and remained clear 36 months postoperatively.
Postoperative inflammation is one of the oldest complications of cataract surgery. It was described by the Indian Susruta as early as 500 BC. Following the introduction of cataract extraction by Daviel in 1745, these operations attracted increasing interest. In 1786 de Wenzel distinguished two types of postoperative inflammation. In the dangerous type there was involvement of the entire eye and severe pain; in the benign type, which began in the first few postoperative days, the conjunctiva and lids were not involved, and even if hypopyon developed there was no severe pain. During the 19th century, the possible causes of the benign type of iritis were discussed, including infection, phacoanaphylaxis, trauma, toxicity of irrigation solutions etc. In the early days of implantation of intraocular lenses, from 1949 onward, postoperative inflammation was common. However, it was not until 1980 that the term "toxic lens syndrome" was introduced. The clinical descriptions do not differ much from other descriptions of benign iritis published during the last 200 years. Therefore, it does not seem that there is any great advantage to be gained by using this new term.
Case report on a child with acute lymphogenous leukemia. Although there was constant hematological remission she developed an isolated leukemic iritis and secondary glaucoma. The clinical picture showed a characteristic stratification of the hyphema. After the patient had remained seated for a prolonged period of time the leukemic cells settled above the erythrocytes, forming a so-called pseudohypopyon, which diagnostically important. Cytologic examination after anterior chamber paracentesis is indispensable in order to establish the etiology of the disease. Isolated leukemic iritis may be the first sign of a relapse and therefore indicate a need to reinstitute induction therapy.
The author presents a case report on a 47-year-old man with recurrent serofibrinous iritis. As a result of intensive investigations an IgG-type myeloma was finally diagnosed with the aid of serum electrophoresis, immunoelectrophoresis, and sternal puncture. Apart from ocular symptoms of acute iritis all findings were normal. General clinical findings were also normal and the patient was subjective free of complaints.
Acute iritis, which is often seen in young adults, may cause red eye, photophobia, and aching discomfort. Many times, the condition can be ameliorated or completely reversed by cautious use of cycloplegic agents and corticosteroids. However, undiagnosed or improperly treated iritis can lead to glaucoma and loss of vision.
The present report describes an iritis-like reaction found in 13 patients treated with recombinant human erythropoietin (Eprex), a drug given to hemodialysis patients for their chronic anemia. Among 120 patients being treated by hemodialysis in two centers affiliated with our medical center, ten out of 30 Eprex-treated patients but none of 90 not being treated with Eprex developed this reaction. The observations described support a causal relation between Eprex treatment and the iritis-like reaction. Further investigative effort is needed to establish the mechanism.
A 37-year-old man was admitted to hospital with fever, muscle tenderness, headache and mild exanthema on the right thigh. During his hospital stay, the headache worsened and aseptic meningitis was diagnosed. A bilateral iritis developed, and the exanthema developed into an atypical erythema nodosum. In liver function tests, pathological results were recorded. Vasculitis was suspected but could not be confirmed. All serological tests proved negative except for a fourfold titre rise to Chlamydia pneumoniae. We concluded that the meningitis, hepatitis, iritis and atypical erythema nodosum were most probably due to a C. pneumoniae infection.
A case of foveomacular retinitis, ankylosing spondylitis, iritis, and iris dissociation is described. Only ankylosing spondylitis was present in other family members. The differential diagnosis is discussed. The iritis of ankylosing spondylitis must be considered in cases of developmental full-thickness iris holes.
