Iritis in leprosy.

Iritis in leprosy is still a significant cause of blindness and visual impairment in this disabling disease. Evidence is accumulating from clinical observations and from pathological and pharmacological studies that the chronic iritis of lepromatous leprosy may have a neuroparalytic origin. A hypothesis derived from this evidence is presented in order to stimulate further research into the pathogenesis of this condition with a view to developing new methods of management and prevention.

Leukemic iritis with hypopyon.

A patient with acute lymphoblastic leukemia who had received CNS sanctuary treatment with cranial X-irradiation and intrathecal methotrexate displayed his first sign of relapse as iritis with malignant hypopyon. Treatment included topical and subconjunctival corticosteroids and local X-irradiation. Leukemic infiltration of the iris may be the first sign of leukemic relapse. Slit-lamp examination should be performed in all leukemic patients with ocular symptoms.

Acute interstitial nephritis and iritis. Renal-ocular syndrome.

Acute renal failure developed in a previously healthy woman in association with acute iritis. Renal biopsy revealed acute mononuclear interstitial nephritis. Known systemic illnesses that can present as acute renal failure and have ocular manifestations of iritis/uveitis were excluded by detailed testing and observation during a 24-month period. No cause for this renal-ocular syndrome was discovered. There was a dramatic improvement to normal renal function and complete resolution of ocular findings following a two-month course of steroid therapy.

Blockage of complement regulators in the conjunctiva and within the eye leads to massive inflammation and iritis.

The open environment of the eye is continuously subject to an influx of foreign agents that can activate complement. Decay-accelerating factor (DAF), membrane cofactor protein (MCP) and CD59 are regulators that protect self-cells from autologous complement activation on their surfaces. They are expressed in the eye at unusually high levels but their physiological importance in this site is unstudied. In the rat, a structural analogue termed 5I2 antigen (5I2 Ag) has actions overlapping DAF and MCP. In this investigation, we injected F(ab')2 fragments of 5I2 mAb into the conjunctiva and aqueous humor, in the latter case with and without concomitant blockage of CD59. Massive neutrophilic infiltration of the stroma and iris resulted upon blocking 5I2 Ag activity. Frank necrosis of the iris occurred upon concomitant intraocular blockage of CD59. C3b was identified immunohistochemically, and minimal effects were seen in complement-depleted animals and in those treated with non-relevant antibody. The finding that blockage of 5I2 Ag function in periocular tissues and within the eye causes intense conjunctival inflammation and iritis demonstrates the importance of intrinsic complement regulators in protecting ocular tissues from spontaneous or bystander attack by autologous complement.

[Rifabutin-induced hypopyon iritis in HIV infection].

BACKGROUND: Rifabutin is a new semisynthetic rifamycin which is approved in Germany for clinical application since 1/15/95. The drug is used for prophylaxis and treatment of Mycobacterium avium intracellulare (MAI) infection in patients with AIDS. In 1994 it was reported that rifabutin can cause anterior uveitis. This side effect is dose-dependent and aggravated, when the drug is combined with clarithromycin and/or fluconazol. PATIENT: A 32-year-old woman suffered from acquired immunodeficiency syndrome and systemic MAI. She was treated with a combination of rifabutin (450 mg/day), clarithromycin (750 mg/day) and ethambutol (800 mg/day). 78 days later she developed a unilateral hypopyon iritis. RESULTS: Rifabutin was discontinued and topical steroids and mydriatics were given. The uveitis disappeared within two weeks. CONCLUSIONS: The ophthalmologist should be aware of this new potential etiology of anterior uveitis. Rifabutin should be withdrawn immediately. Anti-inflammatory eye drops might be helpful.

[Recurrent bilateral iritis in a case of salmonellosis (author's transl)].

Case report on a 24-year-old patient with bilateral recurrent iritis with salmonellosis (bacterial food poisoning). The stool test revealed salmonella typhi murium. It is remarkable that, in spite of a careful general anamnesis, the patient at first failed to mention the gastroenteric symptoms.

Effect of 9-(2-hydroxyethoxymethyl)guanine on herpesvirus-induced keratitis and iritis in rabbits.

Drugs used for the inhibition of DNA viruses, such as iododeoxyuridine, adenine arabinoside, or trifluorothymidine, are not biochemically selective in their action and also interfere with normal cellular functions. The recently reported 9-(2-hydroxyethoxymethyl)guanine (acycloguanosine) is selectively phosphorylated by viral thymidine kinase but not by normal cellular thymidine kinase. Our present studies show that the acycloguanosine is as effective in treating herpetic keratitis in the rabbit as iododeoxyuridine and trifluorothymidine when given topically as an ointment. It is also effective when given intravenously for the treatment of herpetic iritis and is effective in preventing death from encephalitis in rabbits.

Fibrinous iritis due to oxybuprocaine.

Following minor surgery performed under topical application of oxybuprocaine (Dorsacaine, Novesin) two patients suffered from fibrinous iritis and moderate corneal swelling. We believe that this represents a toxic reaction caused by an inadvertent entry of this drug into the anterior chamber during the procedure.

Pouchitis-associated iritis (uveitis) following total proctocolectomy and ileal pouch-to-anal anastomosis in ulcerative colitis.

A 26-year-old woman with ulcerative colitis treated with a proctocolectomy and ileal pouch-to-anal anastomosis developed an erosive and ulcerative pouchitis. Although no ophthalmological manifestations were present before the staged surgical procedures, iritis developed after appearance of the pouchitis. Both conditions subsequently resolved with oral corticosteroids and metronidazole.

[Unilateral iritis by cysticercal larva in the anterior chamber].

An 8-year-old girl complained of progressive pain, visual loss and photophobia in her right eye for 1 week. Treatment with local steroids for acute iritis had not been successful. Slitlamp examination revealed a marked cellular and fibrinous inflammatory reaction of the anterior chamber and a whitish, fibrin-like structure on the surface of the iris. There was mild serum eosinophilia and leucocytosis. The suspected organic material was removed surgically. By light and electron microscopy, parts of the wall of a helminthic parasite were discovered, anatomically consistent with the diagnosis of an immature stage of Taenia solium found in cysticercosis. Such cases of intra-ocular parasitosis are described very rarely but might still occur, although there is no history of suspicious typical exposition to parasites. It is important to know that eosinophilia may be insignificant or even absent and that complete surgical removal will be the only successful treatment.

Placement of a collagen glaucoma drainage device to control intraocular pressure and chronic iritis secondary to juvenile rheumatoid arthritis.

A patient with juvenile rheumatoid arthritis and chronic iritis is reported with intraocular pressure near 30 mm Hg and previous episodes of intraocular pressure as high as 50 mm Hg despite maximally tolerated medical therapy. Because of the potential risk involved with a full-thickness filtration procedure, it was decided that a nonpenetrating deep sclerectomy would be appropriate, followed by placement of a collagen glaucoma drainage device to maintain aqueous outflow. Immediately postoperatively, intraocular pressure was stabilized. At 24 months postoperatively, intraocular pressure was well controlled at 15 mm Hg with patient receiving only Lotemax. No significant complications were noted at any point in the postoperative course. Because of the patient's predisposition for serious complications frequently associated with trabeculectomy, nonpenetrating deep sclerectomy with the collagen glaucoma drainage device was an effective alternative for this patient.

The interrelationship between sex, susceptibility factors, and outcome in ankylosing spondylitis and its associated disorders including inflammatory bowel disease, psoriasis, and iritis.

OBJECTIVE: To examine the evidence that families, where the mother has disease, carry more heritable factors and investigate the effect of maternal/paternal inheritance on phenotypic expression of disease in terms of (a) severity and outcome and (b) additional co-disorders. The children of women with ankylosing spondylitis (AS) develop the disease more often than the children of men. This suggests that either women with disease carry more susceptibility factors than men or that the uterine environment/breast feeding may play a role in AS. METHODS: The number of second degree relatives (i.e., grandparent, aunt/uncle) was calculated for those index patients with a mother with disease as opposed to a father. Outcome measures were compared and prevalence of secondary disorders (i.e., psoriasis, iritis, inflammatory bowel disease) was examined in patients with an AS mother as opposed to an AS father. RESULTS: The affected offspring of maternal cases had more second degree relatives with disease [20% vs 9%, respectively, p = 0.012, odds ratio (OR): 2.3, 95% confidence interval (CI): 1.2, 4.5] than did children of affected men. The affected children of a mother with AS were comparable in terms of disease activity, function, and radiology to children of a father with disease. Inflammatory bowel disease was more prevalent among children of AS mothers than AS fathers (15% vs 5%, respectively, p = 0.009, OR: 2.9, 95% CI: 1.3, 6.3). Psoriasis was less prevalent among sons of AS mothers than among sons of AS fathers (9% vs 22%, respectively, p = 0.03, OR: 0.4, 95% CI: 0.2, 0.9). CONCLUSION: The inherited susceptibility load is strongly linked to the sex of the parent with AS. Women with disease carry higher heritability (which is associated with inflammatory bowel disease) than do men. There is a male sex impact on susceptibility to psoriasis (when AS is present). However, there is no evidence that the susceptibility load has an effect on outcome or severity of disease (as measured by disease activity, function, and radiology), or that outcome is influenced by transmission of maternal as opposed to paternal factors.

[Herpes simplex virus isolations from the aqueous humor of patients suffering from focal iritis, endotheliitis, and prolonged disciform keratitis with glaucoma (author's transl)].

Aqueous humor from 33 herpes patients, 4 zoster patients, and 14 patients with etiologically unclear anterior uveitis was cultured for the presence of herpes viruses. Nine taps from 8 herpes patients with corneal endothelial disease and/or anterior uveitis yielded herpes simplex virus. In the case of one patient two taps were positive at 14 days' interval. Control cultures from the surface of conjunctiva and cornea were consistently virus-negative. Analysis of the virus-positive cases displayed three remarkable features: 1. Secondary glaucoma was uniformly present. This in itself is an indication for culturable herpes simplex virus in the aqueous. 2. Three clinical pictures could be differentiated biomicroscopically: focal iritis, peripheral endotheliitis, and prolonged disciform keratitis. 3. In a proportion of cases, tissue damage resulting from associated immune reactions seems to be more important for the functional outcome than tissue damage by viral cytolysis itself. After having tried several antiviral substances (trifluorothymidine topically, adeninearabinoside-monophosphate intravenously, human leukocyte interferon intramuscularly and intracamerally) we presently favour a topical combination therapy consisting of trifluorothymidine and steroids. This must be complemented by cycloplegics and--in cases of high intraocular pressure--by acetazolamide.

Iritis. How to recognize and manage a potentially sight-threatening disease.

A red eye is a common complaint, often related to benign conditions. However, a red eye in conjunction with symptoms such as photophobia, pain, and decreased visual acuity is an important clue to a much more serious disorder. Iritis is one of these but is reversible with proper use of mydriatic and cycloplegic agents and corticosteroids. Heightened clinical suspicion is necessary for timely diagnosis. The examiner should be skilled in the use of a slit lamp or should refer the patient to an ophthalmologist for immediate evaluation. Once the diagnosis is made, treatment with topical corticosteroids is imperative. Close monitoring is required because overuse of corticosteroids has ominous side effects.

Acute iritis induced by granulocyte colony-stimulating factor used for mobilization in a volunteer unrelated peripheral blood progenitor cell donor.

We describe a volunteer unrelated peripheral blood progenitor cell donor with previously diagnosed dermatitis herpetiformis in whom the administration of G-CSF for the mobilization of precursor cells induced acute iritis. G-CSF has been administered to healthy people with minimal side-effects but when used in patients with autoimmune disorders worsening of symptoms or new manifestations may be a potential concern.
