Patterns of exacerbations of chronic non-infectious uveitis in pregnancy and puerperium.

PURPOSE: To determine patterns of exacerbations of recurrent non-infectious uveitis during pregnancy and puerperium. DESIGN: Retrospective cohort study. METHODS: The medical records of 32 women with a history of chronic non-infectious uveitis, who were pregnant during their follow-up at the Ocular Immunology and Uveitis Service of the Massachusetts Eye and Ear Infirmary, from 1983 through 2003, were reviewed. The uveitis relapse rate during pregnancy was compared to the relapse rate during pregnancy-free periods in these women and to the relapse rate in a control group of women of childbearing age with recurrent non-infectious uveitis. RESULTS: Among the 32 women who were pregnant during follow-up (40 pregnancies), the rate of flare-ups during pregnancy (1.0 recurrence per year) was lower than that observed during non-pregnant periods (2.4 per year; p<0.001) and lower than that observed in the non-pregnant control group (3.1 per year; p<0.001). Flare-ups were most frequent in the first trimester of pregnancy and decreased markedly in the second and third trimesters (2.3, 0.5, and 0.4 recurrences per year, respectively; p<0.001). CONCLUSIONS: Pregnancy is associated with lower numbers of flare-ups of non-infectious uveitis compared to the non-pregnant state. If flare-ups do occur during pregnancy, they happen predominantly in the first trimester.

Analysis of clonal immunoglobulin heavy chain rearrangements in ocular lymphoma.

BACKGROUND: The morphologic diagnosis of primary and metastatic intraocular lymphoma (IOL) was made difficult by the paucicellular specimens with fragile populations of lymphocytes retrieved through pars plana vitrectomy (PPV). The analysis of immunoglobulin heavy chain (IgH) gene rearrangements (AIGHR) was used as an adjunct to cytopathology and flow cytometry in systemic lymphoma. In IOL, the sensitivity and specificity of AIGHR are unknown. METHODS: The authors reviewed the clinical records of patients who underwent PPV for suspicion of IOL at the Immunology and Uveitis Service of the Massachusetts Eye and Ear Infirmary (Boston, MA) between 2000 and 2002. AIGHR was performed as a routine diagnostic test on cell lysates isolated from < 0.5 mL of vitreous fluid. The authors used seminested polymerase chain reaction (PCR) with consensus primers for the VDJ-region of the IgH gene. PCR products were analyzed by polyacrylamide gel electrophoresis. RESULTS: Thirty patients (37 specimens) with chronic vitritis and 17 patients (23 specimens) with IOL were included. The specificity of vitreous fluid cytopathology, flow cytometry, and AIGHR was 1.0, and the sensitivity values were 0.24, 0.36, and 0.64, respectively. AIGHR was negative in two patients for whom cytopathology or flow cytometry revealed the diagnosis of lymphoma. Clonal IGHR was found in four specimens classified as negative for lymphoma based on cytopathology and flow cytometry. CONCLUSIONS: AIGHR supplemented cytopathology and flow cytometry to increase the diagnostic yield in IOL.

Psoriatic uveitis: a distinct clinical entity?

PURPOSE: To describe the clinical characteristics of uveitis occurring in patients with psoriasis and to compare them with patients with idiopathic anterior uveitis and HLA-B27-associated anterior uveitis. DESIGN: Case-control study. METHODS: The charts of 36 patients with a diagnosis of uveitis and psoriasis visiting the Immunology and Uveitis Service at the Massachusetts Eye and Ear Infirmary between January 2000 and December 2001 were reviewed. Clinical characteristics, therapy, and outcomes of uveitis were compared with 30 randomly selected patients with either idiopathic anterior uveitis or with HLA-B27-associated anterior uveitis. RESULTS: The mean age at presentation for uveitis was significantly higher in patients with psoriasis compared with nonpsoriatic groups (44.6 years in HLA-B27-psoriatic patients vs 35.9 years in HLA-B27- nonpsoriatic patients, P = .034; 52.7 years in HLA-B27+ psoriatic vs 35.7 years in HLA-B27+ nonpsoriatic patients, P = .001). Uveitis in patients with psoriasis also tended to be bilateral (62%) and prolonged (11.2 weeks). HLA-B27+ patients with psoriasis required supplemental therapy with oral nonsteroidal anti-inflammatory drugs (95% confidence interval [CI] 1.41 to 5.36, P = .003) for anterior uveitis more often than did the HLA-B27+ nonpsoriatic group. Patients with psoriasis and uveitis who were HLA-B27+ required oral NSAIDs (95% CI 1.51 to 9.79, P = .001) for anterior uveitis more often than did HLA-B27- psoriatic patients. CONCLUSION: Uveitis in patients with psoriasis may have distinguishing clinical features. Further epidemiologic studies are required to determine the strength of association between psoriasis without arthritis but with uveitis.

Successful treatment of idiopathic orbital inflammation with mycophenolate mofetil.

PURPOSE: To report our experience with the use of mycophenolate mofetil for treatment of idiopathic orbital inflammation (IOI). DESIGN: Noncomparative interventional case series. METHODS: We reviewed the records of five patients with IOI who were treated with mycophenolate mofetil. The indications for use included recurrent inflammation after other therapies (four patients) and to avoid corticosteroid-induced blood sugar elevation in poorly controlled diabetes mellitus (one patient). Treated patients were followed for a median of 8.5 months (range, 4-30 months) after mycophenolate mofetil therapy was begun. Main outcome measures were response to treatment, treatment-related side effects, drug dosage, previous and final treatment regimens, and discontinuation of systemic corticosteroids. RESULTS: Mycophenolate mofetil therapy was discontinued in one patient because of nausea. Each of the remaining four patients experienced complete resolution of orbital inflammation. Of these, only one patient remains on prednisone, but at a significantly reduced dose (1 mg/d). CONCLUSION: Mycophenolate mofetil therapy resulted in the resolution of inflammation in patients with refractory or corticosteroid-dependent IOI and was used successfully for a first episode of IOI in a patient for whom corticosteroids were contraindicated.

Ocular pemphigus.

BACKGROUND: Ocular involvement in patients with pemphigus vulgaris (PV) has been rarely reported. We report ocular involvement in 11 patients with PV. METHODS: Medical records of 11 biopsy-proven patients with PV treated during the period between 1990 and 2003 were reviewed and clinical information was analyzed. RESULTS: Mean age at onset of PV was 52.3 years (range, 30-80 years). Ocular disease was preceded by involvement of the skin, other mucosae, or both in all patients. Ocular involvement was limited to the conjunctivae, the eyelids, or both. PV did not affect the visual acuity of any of the patients. Suprabasal acantholysis was observed on routine histologic examination of the conjunctiva and skin of the eyelid. Direct immunofluorescence of perilesional eyelid skin demonstrated deposition of IgG on epithelial cell surface. Mean duration of follow up was 48.9 months (range, 4-100 months). Recurrence of ocular disease occurred in 3 patients; recurrence at nonocular mucosae occurred in 4 patients. No sequelae were observed during detailed follow-up. Ocular pemphigus improved with systemic therapy. The mean remission period was 32 months (range, 0-92 months). CONCLUSIONS: Ocular involvement in PV is rare. Involvement is limited to the conjunctiva, the eyelids, or both. PV does not appear to affect visual acuity. Patients have full recovery without sequelae.

Ahmed valve implantation for uncontrolled pediatric uveitic glaucoma.

PURPOSE: We sought to evaluate the safety and efficacy of Ahmed valve implantation for the management of glaucoma associated with chronic uveitis in pediatric patients. METHODS: A retrospective chart review was conducted of 6 pediatric patients (7 eyes) who underwent Ahmed valve implantation because of refractory uveitic glaucoma. Intraocular pressure (IOP) reduction, preoperative and postoperative visual acuities, the number of hypotensive medications required, and complications associated with the operation were evaluated. RESULTS: Mean follow-up was 36.8 months (range, 6-60). At the last visit, all 7 eyes had IOPs between 9 and 18 mm Hg (average, 12.1). IOP reduction averaged 69.6% (P = 0.0005, paired t-test). The number of hypotensive agents was reduced from an average of 3 to an average of 0.71 medicines per eye (P = 0.001). The only complication was hemorrhagic choroidal detachment postoperatively in two eyes; both resolved within one month. CONCLUSIONS: For children with good immunomodulatory control of their inflammation and appropriate follow-up, Ahmed valve implantation can be an effective and safe procedure for treating pediatric uveitic glaucoma.

Combined pars plana vitrectomy and phacoemulsification to restore visual acuity in patients with chronic uveitis.

PURPOSE: To report the outcomes of combined phacoemulsification and pars plana vitrectomy (PPV) to restore visual acuity in patients with cataract and posterior segment involvement secondary to chronic uveitis. SETTING: Ocular Immunology and Uveitis Service, Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, Massachusetts, USA. METHODS: This study comprised 34 patients (20 women, 14 men; 36 eyes) with posterior segment involvement secondary to chronic uveitis who had combined phacoemulsification and PPV from 1998 to 2002. The main outcome measures were visual acuity, intraocular pressure, and cystoid macular edema. RESULTS: The mean patient age was 45 years +/- 16.09 (SD). The mean duration of uveitis before surgery was 56 +/- 44.17 months. In 24 eyes (66.7%), an intraocular lens (IOL) was implanted during surgery; 12 eyes (33.3%) were left aphakic. Five eyes (13.8%) received an intraocular steroid injection intraoperatively. Visual acuity improved in 26 eyes (72.2%), deteriorated in 5 (13.9%), and was unchanged in 5 (13.9%). The main reason for decreased visual acuity was refractory macular edema. During the follow-up, 2 IOLs were explanted secondary to lens intolerance. One IOL was repositioned because of iris capture by the haptics, and 1 dislocated inferiorly, causing monocular diplopia. The mean follow-up was 23.4 +/- 16.7 months. CONCLUSIONS: Results indicate that combined phacoemulsification and PPV is a feasible technique for the removal of cataract and pathologic vitreous in eyes with chronic uveitis. Although the exact role of vitrectomy in patients with uveitis remains to be determined, the combined surgery successfully restored useful vision in most cases.

Initial evaluation of subcutaneous daclizumab treatments for noninfectious uveitis: a multicenter noncomparative interventional case series.

PURPOSE: To assess the feasibility of a study design that may determine whether subcutaneous administration of the interleukin-2 receptor antibody daclizumab can safely reduce the dependence on standard systemic corticosteroids or other immunosuppressive regimens in patients with sight-threatening, noninfectious intermediate uveitis, posterior uveitis, or panuveitis. DESIGN: Prospective, multicenter, nonrandomized, noncomparative, open-label interventional trial. PARTICIPANTS: Fifteen patients, 5 each at 3 clinical centers, with noninfectious intermediate, posterior, or panuveitis, who require a currently stable immunosuppression regimen of systemic corticosteroids and/or other systemic treatments to control noninfectious intraocular inflammation. METHODS: After enrollment and baseline ophthalmic evaluations, 2 induction treatments were given 2 weeks apart using subcutaneous (SC) daclizumab at 2 mg/kg. Subcutaneous daclizumab maintenance treatments were then continued every 2 weeks at 1 mg/kg for 6 months. The initial immunosuppression load was tapered over 8 to 12 weeks in a staggered fashion beginning with the first induction treatment. Safety evaluations were performed at each treatment visit, with a primary efficacy evaluation at 12 weeks and a repeat efficacy evaluation at 26 weeks. MAIN OUTCOME MEASURES: Best-corrected visual acuity (Early Treatment of Diabetic Retinopathy Study [ETDRS] method) with a concurrent taper of concomitant systemic immunosuppression medication load (tabulated by use of a weighted scoring system) was assessed; target for success was defined as a 50% or greater reduction in concomitant immunosuppression load by 12 weeks while maintaining visual acuity within 5 ETDRS letters of baseline. Ocular inflammation was assessed at each visit with standardized grading scales. RESULTS: Ten of 15 patients (67%) receiving SC daclizumab treatments every other week successfully achieved the primary efficacy end point of reducing their concomitant immunosuppression load by at least 50% while maintaining their baseline visual acuity at 12 and 26 weeks. Subcutaneous daclizumab injections were well tolerated with no serious adverse events observed during the 6 months of treatments, although 3 patients experienced possibly related, nonserious adverse events. CONCLUSIONS: Subcutaneous daclizumab induction treatments at 2 mg/kg followed by 1 mg/kg maintenance treatments every other week seems safe and, in most cases, may reduce the concomitant immunosuppressive load required to treat noninfectious uveitis for 12 to 26 weeks.

Long-term follow-up of patients with birdshot retinochoroidopathy treated with corticosteroid-sparing systemic immunomodulatory therapy.

PURPOSE: To evaluate the outcomes of patients with birdshot retinochoroidopathy (BSRC) treated with corticosteroid-sparing systemic immunomodulatory therapy (IMT). DESIGN: Retrospective, noncomparative, interventional case series. PARTICIPANTS: Thirty-five patients with BSRC evaluated at the Ocular Immunology and Uveitis Service of the Massachusetts Eye and Ear Infirmary from 1980 through 2003. METHODS: Data on age, gender, follow-up time, delay to diagnosis or referral, treatment before and during follow-up, complications of BSRC or treatment, Snellen visual acuities (VAs), and electroretinograms (ERGs) were recorded from patient charts. MAIN OUTCOME MEASURES: Disease progression as determined by Snellen VAs and serial ERGs, ocular complications of BSRC or corticosteroids, and complications of systemic IMT. RESULTS: Twenty-eight patients with a mean follow-up of 81.2 months were included. None of the patients had sufficient control of their inflammation before referral. All patients were treated with corticosteroid-sparing systemic IMT at some point during their follow-up: 92.9% were treated with cyclosporine, 67.9% with mycophenolate mofetil, 17.9% with azathioprine, 10.7% with oral methotrexate, and 7.1% with daclizumab. Ocular complications of BSRC and/or corticosteroids were cataract (53.6%), cystoid macular edema (35.7%), glaucoma (21.4%), epiretinal membrane (10.7%), and retinal detachment (3.6%). Average Snellen VAs at the time of initial visit were 0.64 (right eye) and 0.59 (left eye). Average final Snellen VAs were 0.74 (right eye) and 0.71 (left eye). (Logarithm of the minimum angle of resolution equivalents were -0.23, right eye initial; -0.19, right eye final; -0.38, left eye initial; and -0.31, left eye final.) In the right eye, 78.6% of patients and, in the left eye, 89.3% of patients had either the same or improved VA at the end of the follow-up. The 30-hertz flicker implicit time was prolonged in 58.3% of initial ERGs and in 62.5% of final ERGs. The bright scotopic amplitude was abnormal in 45.5% of initial and final ERGs. CONCLUSIONS: Long-term preservation of visual function is attainable with systemic corticosteroid-sparing IMT for patients with BSRC. Prompt treatment with systemic IMT may offer the best hope of maintaining retinal function in what is often thought of as a chronically progressive disease resistant to treatment.

Discoid lupus erythematosus masquerading as chronic blepharoconjunctivitis.

PURPOSE: To recognize discoid lupus erythematosus (DLE) as a treatable cause of chronic blepharoconjunctivitis. DESIGN: Retrospective observational case series. PARTICIPANTS: Records of 5 patients with biopsy-proven DLE were reviewed. METHODS: Clinical and pathology records were examined. MAIN OUTCOME MEASURES: Patients' clinical and histopathological characteristics and response to treatment were assessed. RESULTS: Clinical features included meibomian gland dysfunction, blepharitis, chalazia, trichiasis, madarosis, conjunctivitis, chronic eyelid edema, and eyelid plaques. Histopathology showed hyperkeratotic epithelium, degeneration of the basal cell layer, and a perivascular lymphocytic infiltrate. There was delayed diagnosis in all cases, ranging from 4 months to 25 years. All of the patients responded to systemic hydroxychloroquine therapy. CONCLUSIONS: Heightened awareness of eyelid DLE may lead to earlier detection and specific therapy for this chronic disorder.

Analysis of pediatric uveitis cases at a tertiary referral center.

OBJECTIVE: To analyze demographics, anatomic data, diagnoses, systemic associations, and visual outcomes of pediatric patients in a large tertiary eye center. DESIGN: Retrospective cohort study. METHODS: The records of 1242 patients with uveitis referred to the Ocular Immunology and Uveitis Service of the Massachusetts Eye and Ear Infirmary (MEEI) from 1985 to 2003 were reviewed retrospectively. Two hundred sixty-nine patients 16 years and younger were identified. RESULTS: Among 269 children with uveitis, 53.5% were girls, 82% were Caucasian, and 82% were born in the United States. Mean age was 8 years (standard deviation, 3.8; range, 1-16). Anterior uveitis represented 56.9% of cases; intermediate, 20.8%; panuveitis, 16%; and posterior, 6.3%. Nongranulomatous (77.6%) and noninfectious (85.7%) were the most frequent types of inflammation. The process was bilateral in 74.4% of patients. Mean follow-up was 22 months, with mean age of 8 years at diagnosis. Mean duration of uveitis at the time of presentation at the MEEI was 2 years. The range of time between the diagnosis of uveitis and referral was 1 day to 5.6 years. The length of time between diagnosis of uveitis and the referral to the tertiary center strongly correlated with the complication rate and degree of visual impairment in our study. The longer the time before the patients were seen by the uveitis expert, the worse the visual outcomes. No systemic associations were found in 58% of patients, juvenile idiopathic arthritis was responsible for 33% of cases, 8% of patients had other systemic associations, and 1% had tubulointerstitial nephritis uveitis syndrome. CONCLUSIONS: Uveitis remains a serious cause of morbidity and visual loss in children. Timely referral to uveitis specialists in the tertiary referral centers may lead to improved visual outcomes in children with chronic uveitis.

Stevens-Johnson syndrome and toxic epidermal necrolysis: a review of the literature.

OBJECTIVE: To perform a comprehensive review of Stevens-Johnson syndrome and toxic epidermal necrolysis. DATA SOURCES: A MEDLINE search was performed for the years 1975 to 2003 using the keywords Stevens-Johnson syndrome and toxic epidermal necrolysis to identify relevant articles published in English in peer-reviewed journals. STUDY SELECTION: All clinical studies that reported on 4 or more patients, review articles, and experimental studies that concerned disease mechanisms were selected and further analyzed. Clinical reports that included fewer than 4 patients were selected only if they were believed to carry a significant message about disease mechanism or therapy. RESULTS: Stevens-Johnson syndrome and toxic epidermal necrolysis seem to be variants of the same disease with differing severities. A widely accepted consensus regarding diagnostic criteria and therapy does not exist at present. Despite the recent experimental studies, the pathogenic mechanisms of these diseases remain unknown. Although progress in survival through early hospitalization in specialized burn units has been made, the prevalence of life-long disability from the ocular morbidity of Stevens-Johnson syndrome and toxic epidermal necrolysis has remained unchanged for the past 35 years. Further progress depends on modification of the acute phase of the disease rather than continuation of supportive care. The available published evidence indicates that a principal problem in the pathogenesis is immunologic and that immunomodulatory intervention with short-term, high-dose intravenous steroids or intravenous immunoglobulin holds the most promise for effective change in survival and long-term morbidity. CONCLUSIONS: The results of this review call for a widely accepted consensus on diagnostic criteria for Stevens-Johnson and toxic epidermal necrolysis and multicenter collaboration in experimental studies and clinical trials that investigate disease mechanisms and novel therapeutic interventions, respectively.

Masquerade scleritis.

PURPOSE: To report two cases in which malignancy masqueraded as scleritis, delaying the diagnosis. METHODS: Two patients initially diagnosed and treated for unilateral scleritis were referred for management of persistent inflammation. Additional evaluation uncovered underlying malignant processes. RESULTS: The first patient presented with scleritis initially responsive to systemic corticosteroids, with relapse one month later. Upon referral, peripheral fundus examination revealed elevated lesions. Additional studies confirmed the diagnosis of choroidal melanoma. The patient was treated with proton-beam irradiation. The second patient developed necrotizing scleritis unresponsive to systemic steroids, methotrexate, and cyclophosphamide. A scleral biopsy disclosed an undifferentiated high-grade carcinoma, likely metastatic. Exenteration was performed. CONCLUSIONS: Scleritis can present a diagnostic challenge. It is often the sole initial manifestation of an occult systemic problem. Treatment-resistant scleritis should raise the suspicion of an infectious or malignant masquerade.

Eosinophil activation in Wegener's granulomatosis: a harbinger of disease progression?

PURPOSE: To investigate the relation between eosinophil activation in tissue from patients with an active, limited form of Wegener's granulomatosis (WG) affecting the eye and subsequent systemic disease activity. METHODS: Analysis of ocular specimens obtained from 10 patients was performed. Sections were probed with antibodies to assess the presence of major basic protein (MBP) and eosinophil cationic protein (ECP). RESULTS: Four of the 10 specimens demonstrated the presence of MBP and ECP. WG progressed to the complete form in two of these patients, who received no or inadequate treatment. The other two, treated with cyclophosphamide for one year, did not progress to the complete form of WG during observation after therapy. CONCLUSIONS: Activated eosinophils in sclera or conjunctiva of patients with ocular limited WG may predict progression to complete WG.

Somatostatin for Uveitic Cystoid Macular Edema (CME).

PURPOSE: To report the favorable response of bilateral recalcitrant uveitic cystoid macular edema (CME) to treatment with a somatostatin analog. METHODS: Medical ophthalmic history and the results of ophthalmic examinations were recorded. Fluorescein angiography (FA) studies were reviewed. RESULTS: A 52-year-old white female with intermediate uveitis developed bilateral recalcitrant CME. Treatment with subcutaneous injections of the somatostatin analog octreotide resulted in partial resolution of the CME and improvement of visual acuity. CONCLUSIONS: Somatostatin may play a role in the treatment of CME secondary to uveitis.

Mucous membrane pemphigoid: an update.

PURPOSE OF REVIEW: To review articles on mucous membrane pemphigoid, published between June 2004-May 2005. RECENT FINDINGS: Decreased glycosylation of mucin was found in patients with ocular cicatricial pemphigoid. A unique antigen in oral mucous membrane pemphigoid has not yet been identified. Increased vascular cell adhesion molecule and intercellular adhesion molecule 1 expression was found in skin of patients affected by mucous membrane pemphigoid. Autoreactive T cells to an epitope of bullous pemphigoid antigen 180 kilodaltons were identified in the blood of some patients with mucous membrane pemphigoid. Circulating IgA against an antigen in mucous membrane pemphigoid was found in about 20% of patients, without prognostic significance. Enhanced sensitivity for direct immunofluorescence was reported if skin biopsy specimens were stored for 24 hours in saline. An enzyme-linked immunosorbent assay for detection of circulating autoantibodies against laminin-5 was developed. Sensitivity was higher than indirect immunofluorescence on salt-split skin and immunoblotting. Patients with younger onset (<60 years) of ocular cicatricial pemphigoid were found to have disease evolution similar to that of an older group (>70 years) but were visually impaired earlier in life. Intravenous immunoglobulin as treatment of ocular cicatricial pemphigoid was found to be superior to conventional immunosuppressants, with fewer side effects and better long-term outcome for halting disease activity. Intraoperative adjunction of mitomycin C during fornix reconstruction with amniotic membrane resulted in achieving a deeper fornix in 83% of patients with various cicatrizing conjunctivitis. Transplantation of cultured epithelial cells of oral mucosa in corneal limbal stem cell deficiency was successful in improving visual acuity and reestablishing corneal transparency in mid- to advanced ocular cicatricial pemphigoid. SUMMARY: Further advances have been achieved in the field of mucous membrane pemphigoid.
