Multifocal choroiditis and panuveitis. A syndrome that mimics ocular histoplasmosis.

A review of 28 cases of multifocal choroiditis with vitreous inflammatory cells demonstrates that these patients have chorioretinal scars similar to those in the presumed ocular histoplasmosis syndrome (POHS), but they have a low incidence of positive histoplasmin skin test reactions and calcified granulomata on chest x-ray films. Anterior chamber inflammation is a frequent finding. The epidemiologic background of these patients is different from those with POHS. The subjects in this study were also different from patients with birdshot or vitiliginous choroiditis and acute posterior multifocal placoid pigment epitheliopathy. However, unilateral cases are difficult to distinguish from cases of diffuse unilateral subacute neuroretinitis. While it is possible that a subretinal nematode may have caused some of the unilateral cases in this review, multiple causative agents are likely, including an unidentified agent that causes cross reactions to histoplasmin skin tests.

Epstein-Barr viral antibodies in multifocal choroiditis and panuveitis.

A syndrome of multifocal choroiditis, pigment epithelial disturbance, and inflammatory vitreous cells was found to be associated with Epstein-Barr virus specific antibodies. The ten patients in this series had positive viral capsid antigen IgM or Epstein-Barr early antigen antibody titers. Patients with this syndrome were generally healthy and had no history of a clinical episode of infectious mononucleosis. No patient from the control group with other ocular diseases had positive viral capsid antigen IgM or early antibody titers. All patients in the study group and most of the control patients had viral capsid antigen IgG and Epstein-Barr nuclear antigen antibodies, indicating a previous exposure to the virus as expected in an adult population.

[Acquired ocular toxoplasmosis (panuveitis) after liver transplantation].

We present one case of acquired Toxoplasma gondii retinochoroiditis after livrer transplantation. Three weeks after receiving liver transplant from a seropositive donor for Toxoplasma gondii, the fundus examination showed a vitreal haze and an edematous retinal lesion with retinal hemorrhages. Routine screening tests for uveitis were performed. The serum toxoplasmosis titers revealed a seroconversion for toxoplasmosis (pre-transplantation tests were negative). The PCR assay on aqueous humor resulted in an amplified product identical to toxoplasmosis. This immunocompromised patient likely received an infected hepatic transplant. The patient's ocular inflammation cleared on 1-month pyrimethamine-sulfadiazine medication. Four months later, the patient developed a retinal detachment with massive proliferative vitreoretinopathy.

Seasonal hyperacute panuveitis of unknown etiology.

A severe form of unilateral uveitis, which in most cases leads to blindness within hours of its onset, has been seen in Nepal since 1975. This disease appears with the onset of autumn in early September and lasts until the end of December in two-year cycles (1975, 1977, 1979). However, some cases occurred in 1980 as well. As expected there was an outbreak of this disease in 1981. Although early cases were seen in patients from Western Nepal, the disease has since been identified in patients from various parts of the country. In one of the outbreaks (1977) in western Nepal some patients or their parents gave a history of a white moth sitting on the child's face or arm prior to the onset of ocular symptoms. Some of these were claimed to be followed by blister formation at the point of contact. These moths were presumed to be responsible for producing this uveitis in those cases. The present report describes the clinical features of the cases seen from the time the disease was first recognized, case histories of four cases seen during the last outbreak, results of laboratory experiments using the aqueous humor of these patients, and the results of experiments using three different varieties of moths.

Panuveal malignant mesenchymoma.

Intraocular malignant mesenchymal tumors are very rare, and only a few case reports of such primary and metastatic tumors have been reported. We report a case of a malignant mesenchymoma involving the entire uveal tract. A 21-year-old woman presented with a tumor on the whole iris of the right eye, which caused intractable glaucoma. Upon enucleation of the eye, a very anaplastic tumor was found to occupy the whole uveal tract; its features were compatible with a tumor of mesenchymal origin, including rhabdomyosarcomatous and liposarcomatous characteristics. Choroidal osteoma was a coincidental finding. The histologic findings of the tumor were of two types of malignant mesenchymal tumors, and therefore the diagnosis of malignant mesenchymoma was made. This is to our knowledge the first tumor of its kind to be reported intraocularly.

Uveitis in the southeastern United States.

PURPOSE: Previous epidemiologic studies of uveitis have focused on predominantly Caucasian populations, and none have been based in the Southeast. We analyzed the epidemiology of uveitis among a referral population with a high percentage of African Americans in the United States. METHODS: We evaluated demographic data from 385 consecutive patients referred to the Duke Uveitis Clinic. RESULTS: Of the 385 patients, 120 (31%) were African American and 258 (67%) Caucasian; 237 (62%) were female and 148 (38%) male. The most common diagnoses among the 385 patients were idiopathic panuveitis (64 patients [17%]), idiopathic anterior uveitis (47 patients [12%]), pars planitis (46 patients [12%]), sarcoidosis (44 patients [11%]), and toxoplasmosis (39 patients [10%]). These diagnoses were also the most common among the 120 African American patients: 33 patients (28%) had idiopathic panuveitis, 30 (25%) had sarcoidosis, 10 (8%) had idiopathic anterior uveitis, 8 (7%) had toxoplasmosis, and 6 (5%) had pars planitis. Among the 258 Caucasian patients, the most common diagnoses were pars planitis (39 patients [15%]), idiopathic anterior uveitis (37 patients [14%]), toxoplasmosis (30 patients [12%]), idiopathic panuveitis (28 patients [11%]), and multifocal choroiditis and panuveitis (MCP) (17 patients [7%]). Categorizing diagnoses of all 385 patients by anatomic location, panuveitis was most frequent (148 patients [38%]), followed by anterior uveitis (97 patients [25%]), posterior uveitis (93 patients [24%]), and intermediate uveitis (47 patients [12%]). CONCLUSIONS: The higher frequency of sarcoidosis and idiopathic panuveitis than previously reported is related to our larger African American population base. The racial composition of the Southeast does not, however, account for differences such as our higher percentage of MCP; it is possible that other genetic or environmental factors play a role in this region.

Clinical patterns and associated conditions in chronic uveitis.

We determined the relative frequencies of the different types of chronic uveitis, and the possible associated conditions, among 400 consecutive patients with chronic uveitis examined during the years 1982 through 1988. Of the 400 patients, 183 (45.75%) had anterior uveitis, 98 (24.5%) ahd panuveitis, 61 (15.3%) had intermediate uveitis, and 58 (14.5%) had isolated posterior uveitis. Only four of the 98 patients with panuveitis (4.1%) were considered idiopathic after a comprehensive examination, whereas 94 of the 183 patients with anterior uveitis (51.4%) were similarly classified. We found an associated condition in 242 of the 400 patients of the study group (60.5%). Of these 242 patients, 61 had Behçet's disease, which constituted the most frequently encountered associated condition in this study. Of the 61 patients with Behçet's disease, 58 had panuveitis and constituted 59.2% of the panuveitis group. Of the 61 patients with intermediate uveitis, 17 (27.9%) had a concurrent disease. An associated condition was found in 95% and 96.2% of patients with unilateral and bilateral panuveitis, respectively, but in none of the patients with unilateral intermediate uveitis. Environmental, cultural, or genetic factors may be accountable for the differences discovered between our findings and those of previously published studies from the United States and England with respect to relative frequencies of some of the associated diseases in patients with chronic uveitis.

Multiplex cytokine detection versus ELISA for aqueous humor: IL-5, IL-10, and IFNgamma profiles in uveitis.

PURPOSE: The purpose of this study was to determine levels of IL-2, -4, -5, -10, TNF-alpha, and IFN-gamma in aqueous humor (AH) from patients with active panuveitis, anterior uveitis (AU), and noninflammatory controls by using a flow cytometric mutiplex array (CBA) and to compare with results from ELISA. METHODS: Pooled normal AH was spiked with six cytokines at decreasing concentrations for evaluating the CBA. AH was also obtained from 10 controls (cataract patients) and 36 patients with active uveitis. Cell-free supernatants were added to a cocktail of capture beads and detector antibodies or to antibody-coated wells for CBA and ELISA determination, respectively. RESULTS: CBA demonstrated greater sensitivity for detecting IL-4, IL-10, and TNF-alpha than with ELISA. Increased IFN-gamma was detected in both AU and panuveitis groups compared with controls (P < 0.01). IL-10 was higher in the panuveitis group on steroids (P < 0.01). IL-5 was detected in the control (P < 0.01) and AU groups (P < 0.05) but was undetectable in the panuveitis group (n = 10). Correlations between IFN-gamma and IL-10 were found in all uveitis groups (P < 0.01) but not in controls, whereas TNF-alpha correlations with IL-4/IFN-gamma were obtained in controls but not in the uveitis groups (P < 0.01). CONCLUSIONS: It was possible to measure cytokines titrated into normal AH specimens by CBA, and a greater number of cytokines were detected with increased sensitivity than with ELISA. Elevated IFN-gamma in active uveitis and decreased IL-5 in posterior uveitis suggest Th1 polarity is more marked, with greater uveal tract involvement. The increased IL-10 in the steroid treated group suggests glucocorticoid-induced IL-10 upregulation.
