Retinal vasculitis and posterior pole "hypopyons" as early signs of acute bacterial endophthalmitis.

PURPOSE: To report a case of acute postoperative bacterial endophthalmitis presenting with retinal vasculitis and posterior pole "hypopyons." DESIGN: Observational case report. METHODS: Observational case report. RESULTS: In a 73-year-old woman, acute postoperative endophthalmitis presented with retinal vasculitis, diffuse retinal hemorrhages, and several posterior pole "hypopyons" that were collections of yellow-white inflammatory debris. The inflammation was located primarily in the posterior one third of the vitreous, and except for severely impaired visual acuity, the classic signs of acute postoperative endophthalmitis were not present until the next day. An immediate pars plana vitrectomy with intravitreal injection of vancomycin, amikacin, and dexamethasone was performed. Vitreous and aqueous cultures grew coagulase-negative Staphylococcus species. After intravenous and topical therapy for endophthalmitis, the inflammation subsided. Eight weeks after the initial cataract surgery, the best corrected visual acuity of the patient was 20/25. CONCLUSION: Acute postoperative bacterial endophthalmitis may present with atypical clinical signs and inflammation located primarily in the retina and posterior vitreous.

Phacoemulsification cataract extraction and posterior chamber lens implantation in patients with uveitis.

PURPOSE: This study reports outcomes of phacoemulsification cataract extraction and posterior chamber intraocular lens implantation within the capsular bag in patients with uveitis. METHODS: We retrospectively reviewed the charts of 32 patients (39 eyes) with uveitis who underwent phacoemulsification cataract extraction and posterior chamber intraocular lens implantation by two surgeons at The Cleveland Clinic Foundation from January 1990 to June 1998. Patients with less than 3 months of follow-up were excluded. RESULTS: Diagnoses of uveitis included idiopathic (15 eyes), sarcoidosis (10 eyes), pars planitis (four eyes), CMV retinitis (two eyes), Fuchs heterochromic iridocyclitis (two eyes), syphilis (two eyes), and one eye each of tuberculosis, Crohn's disease, HLA-B27 associated, and acute retinal necrosis. Average follow-up was 20 months (range, 3 to 63 months). Best-corrected visual acuity improved in 37 eyes (95%). Average improvement was 4 +/- 3 Snellen acuity lines (range, 1 to 10 lines). Thirty-four eyes (87%) attained final visual acuity better than or equal to 20/40. Visual loss occurred in one eye (3%) with CMV retinitis. No improvement in visual acuity was seen in one eye (3%) that developed a retinal pigment epithelial detachment. Posterior capsule opacification occurred in 24 eyes (62%), 12 of which required Nd:YAG capsulotomy (31%). Other postoperative complications included recurrence of uveitis (41%), cystoid macular edema (33%), epiretinal membrane formation (15%), and posterior synechiae (8%). CONCLUSIONS: Phacoemulsification cataract extraction with posterior chamber intraocular lens implantation is safe in patients with uveitis. The incidences of recurrence of uveitis, cystoid macular edema, epiretinal membrane, and posterior synechiae were lower than those reported previously for extracapsular cataract extraction.

Immune recovery vitritis and uveitis in AIDS: clinical predictors, sequelae, and treatment outcomes.

PURPOSE: To determine 1) clinical predictors of an inflammatory syndrome associated with cytomegalovirus (CMV) retinitis (immune recovery vitritis or uveitis [IRV or IRU]); 2) clinical sequelae of IRV; and 3) the effect of corticosteroid treatment on visual acuity. METHODS: A cohort study from the AIDS Ocular Research Unit of the University of California, San Diego, and a case series from the Cleveland Clinic consisted of patients who had acquired immunodeficiency syndrome and inactive CMV retinitis who responded to highly active antiretroviral therapy (HAART) with CD4 T-lymphocyte levels >60 cells/mm3. The cohort was followed for a median of 13.5 months following increase in CD4 count. The authors studied the occurrence of IRV, defined as symptomatic (vision decrease and/or floaters) vitritis of 1+ or greater severity associated with inactive CMV retinitis. Macular edema or epiretinal membrane formation was determined by clinical examination and fluorescein angiography. Five eyes were treated with sub-Tenon corticosteroid injections. RESULTS: In the cohort study, 19 (63%) of 30 HAART responders developed IRV (26 eyes). The clinical spectrum of inflammation included vitritis, papillitis, macular edema, and epiretinal membranes. Eyes with CMV surface area >30% of the retina were at the highest risk (relative risk = 4.5) of developing IRV (P = 0.03). During follow-up, inflammation persisted without treatment for a median of 20 weeks and 14 patients (16 eyes) developed macular changes. Treatment resulted in vision improvement without reactivation of retinitis. Histology and immunohistochemistry of associated epiretinal membranes showed evidence of chronic inflammation with a predominant T-lymphocyte cell population. In the case series, 3 (38%) of 8 HAART responders developed IRV (4 eyes). All four eyes were treated and resulted in visual acuity improvement of one line. CONCLUSIONS: Symptomatic IRV or IRU develops in a significant number of patients with CMV retinitis following successful HAART. Eyes with CMV surface area >30% of the retina are at the greatest risk. Eyes with IRV respond favorably to antiinflammatory therapy without reactivation of retinitis. Immune recovery vitritis may be the result of an immunologic reaction to latent CMV antigens in the eye in which T-lymphocytes play a role.

Corticosteroid therapy for optic disc neovascularization secondary to chronic uveitis.

PURPOSE: To report successful corticosteroid treatment of optic disc neovascularization associated with uveitis. METHODS: Retrospective review of medical records. RESULTS: Nine patients were identified with chronic uveitis and optic disc neovascularization without clinical or angiographic evidence of retinal ischemia. Ages ranged from 14 to 37 years (median age, 27). All patients were treated with either oral and/or subtenon's corticosteroids. Partial regression of the neovascularization was observed in all patients within 2 to 6 weeks (median, 5 weeks) after initiating treatment. Eight of nine patients had complete resolution of disc neovascularization at a median of 3 months (range, 2 to 42 months) after initiation of treatment and a median follow-up of 24 months (range, 7 to 144 months). Recurrence of disc neovascularization occurred in two patients, but it regressed again after further corticosteroid therapy. CONCLUSIONS: Optic disc neovascularization may occur in patients with chronic uveitis in the absence of retinal ischemia. This neovascularization can be successfully treated with corticosteroids.

Cicatrizing conjunctivitis associated with paraneoplastic lichen planus.

PURPOSE: To report two cases of cicatrizing conjunctivitis associated with paraneoplastic lichen planus. METHODS: Case reports. RESULTS: Two patients were examined because of redness and discomfort in both eyes. A 63-year-old woman with follicular, small-cleaved cell lymphoma had cicatrizing conjunctivitis, stomatitis, vulvitis, and skin lesions. A 25-year-old man with malignant thymoma had cicatrizing conjunctivitis, erosive stomatitis, and penile papules. Histopathologic studies of conjunctiva and skin biopsy specimens in the first patient and labial biopsy specimens in the second revealed lichen planus. CONCLUSION: Paraneoplastic lichen planus is a possible cause of cicatrizing conjunctivitis associated with inflammatory skin and mucous membrane disease.

Should all patients with candidaemia have an ophthalmic examination to rule out ocular candidiasis?

PURPOSE: To determine the incidence of ocular candidiasis and length of ophthalmic follow-up required to rule out ocular candidiasis in candidemia patients. METHODS: We prospectively studied patients with candidemia at our institution. Eligibility criteria included a dilated ophthalmological examination within 72 h of fungemia. Patients without ocular candidiasis on initial examination had follow-up dilated ophthalmoscopy performed at 1, 2, 4, 12 and 24 weeks. RESULTS: Between May 1996 and March 1997 a total of 50 patients with fungemia were identified of whom 31 were included in the study; 15 excluded patients died before an initial examination was performed. The overall incidence of ocular candidiasis was 26% (8/31 patients), all manifested as chorioretinitis. Five patients (16%) had ocular candidiasis on their initial examination. One of 21 patients (5%) without ocular candidiasis on initial examination developed ocular candidiasis within 1 week. Two of 16 patients (13%) without ocular candidiasis on initial examination or at 1 week follow-up developed ocular candidiasis within 2 weeks. No evidence of ocular candidiasis occurred in the 12 patients with follow-up at 4 weeks, the 8 patients with follow-up at 12 weeks and the 4 patients with follow-up at 24 weeks. CONCLUSION: The incidence of ocular candidiasis among hospitalized patients is clinically significant. We recommend ophthalmological follow-up for development of ocular candidiasis for at least 2 weeks after an initial negative eye examination.

Endogenous endophthalmitis: case report and brief review.

Endogenous endophthalmitis is a potentially blinding ocular infection resulting from hematogenous spread from a remote primary source. The condition is relatively rare but may become more common as the number of chronically debilitated patients and the use of invasive procedures increase. Many etiologic organisms (gram-positive, gram-negative and fungal) have been reported to cause endogenous endophthalmitis. Risk factors are well defined and include most reasons for immune suppression. A high clinical suspicion is needed for early diagnosis and treatment. Early intravenous antibiotic therapy remains the cornerstone of treatment. The roles of intravitreal antibiotics and vitrectomy are evolving and may become more widely accepted as therapeutic modalities. The authors report a case of endogenous endophthalmitis and provide a brief review of the literature.

Haemophilus influenzae associated scleritis.

AIMS: To describe the clinical course and treatment of Haemophilus influenzae associated scleritis. METHODS: Retrospective case series. RESULTS: Three patients developed scleritis associated with ocular H influenzae infection. Past medical history, review of systems, and laboratory testing for underlying collagen vascular disorders were negative in two patients. One patient had arthritis associated with an antinuclear antibody titre of 1:160 and a Westergren erythrocyte sedimentation rate of 83 mm in the first hour. Each patient had ocular surgery more than 6 months before developing scleritis. Two had cataract extraction and one had strabismus surgery. Nodular abscesses associated with areas of scleral necrosis were present in each case. Culture of these abscesses revealed H influenzae in all patients. Treatments included topical, subconjunctival, and systemic antibiotics. Scleral inflammation resolved and visual acuity improved in each case. CONCLUSION: H influenzae infection may be associated with scleritis. Accurate diagnosis and treatment may preserve ocular integrity and good visual acuity.

Posterior segment inflammation in HLA-B27+ acute anterior uveitis: clinical characteristics.

PURPOSE: To examine clinical characteristics of patients who have posterior segment manifestations in HLA-B27-associated acute anterior uveitis. METHODS: Medical records of 114 HLA-B27-positive patients with acute anterior uveitis were reviewed in a retrospective fashion. Criteria for inclusion were the presence of acute anterior uveitis, a positive HLA-B27 antigen, and one of the following findings: vitreous cells >/=+2; cystoid macular edema; papillitis; vasculitis; or pars plana exudates. Twenty-four patients met the inclusion criteria. RESULTS: Posterior segment manifestations were found in 24 (21.05%) of 114 patients with HLA-B27+ acute anterior uveitis. Eighteen patients had diffuse vitritis (75%), seven had cystoid macular edema (29.1%), and two had papillitis (8.3%). Three patients had more than one finding. The prevalence of associated systemic disease (15 of 24 patients, 62.5%) and hypopyon (6 of 24 patients, 25%) in patients with posterior segment involvement was significantly higher than in the group of patients without posterior segment involvement (systemic disease, 33 of 90, 36.7%, p=0.04, exact chi-quare test; hypopyon, 4 of 90, 4.4%, p=0.006, exact chi-square test). The mean visual acuity at the last visit was 20/30 (range 20/20-20/100). Immunosuppressive therapy (other than corticosteroids) and surgical intervention were not required in the treatment of patients with posterior segment manifestations. CONCLUSION: HLA-B27+ anterior uveitis is associated with posterior segment manifestations. Patients with posterior segment involvement have a significantly higher incidence of associated systemic diseases and hypopyon.

Long-term follow-up of extracapsular cataract extraction and posterior chamber intraocular lens implantation in patients with uveitis.

OBJECTIVE: The objective of the study was to determine the long-term outcome of patients with uveitis who underwent extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens (PCIOL) implantation. DESIGN: Retrospective review. PARTICIPANTS: Twenty-eight patients (36 eyes). INTERVENTION: Extracapsular cataract extraction and PCIOL implantation. MAIN OUTCOME MEASURES: Level of best-corrected Snellen visual acuity, change in visual acuity, length of follow-up, long-term findings, and complications. RESULTS: In long-term follow-up (mean, 81.4 months), 94% of eyes had visual acuity improvement compared with preoperative levels. Average change in visual acuity for all eyes was an improvement of 6.4 Snellen lines; 75% of eyes were 20/40 or better. The prevalences of cystoid macular edema (CME), epiretinal membrane (ERM), and posterior capsule opacification (PCO) were 56%, 56%, and 58%, respectively. CONCLUSIONS: Patients with uveitis who are treated with ECCE with PCIOL implantation can have successful visual results in long-term follow-up despite the prevalence of PCO or macular abnormalities such as CME and ERM.

Optic nerve head neovascularization in a patient with inactive cytomegalovirus retinitis and immune recovery.

PURPOSE: To report a case of optic nerve head neovascularization in a patient with acquired immunodeficiency syndrome (AIDS) associated with inactive cytomegalovirus retinitis and immune recovery. METHOD: Case report. RESULTS: We examined a 29-year-old man with AIDS and inactive cytomegalovirus retinitis and found vitritis and prominent optic nerve head neovascularization. The patient had been treated with reverse transcriptase and protease inhibitors, resulting in a notable rise in CD4+ lymphocyte count and an undetectable human immunodeficiency virus (HIV)-RNA viral load. No cause of neovascularization other than intraocular inflammation was detected. CONCLUSION: Immune recovery in a setting of inactive cytomegalovirus retinitis can result in optic nerve head neovascularization, as seen in our patient.

Chest computed tomography and mediastinoscopy in the diagnosis of sarcoidosis-associated uveitis.

PURPOSE: To report the usefulness of chest computed tomography and mediastinoscopy in diagnosing sarcoidosis in elderly patients with uveitis. METHODS: Case reports. Two Caucasian women, aged 73 and 70 years, underwent evaluations for uveitis, which included chest computed tomography and mediastinoscopy. RESULTS: A chest computed tomographic scan of each woman disclosed mediastinal lymphadenopathy and warranted mediastinal lymph node biopsy by mediastinoscopy. In both patients, histopathologic and microbiologic studies demonstrated sterile noncaseating granulomas consistent with the diagnosis of sarcoidosis. CONCLUSIONS: The diagnosis of sarcoid-associated uveitis in the elderly may be facilitated by chest computed tomography, which may be more sensitive than conventional chest roentgenography. Laboratory studies of biopsied mediastinal nodes obtained by mediastinoscopy can confirm the diagnosis.

Immune recovery vitritis associated with inactive cytomegalovirus retinitis: a new syndrome.

OBJECTIVE: To describe a syndrome of posterior segment intraocular inflammation that causes visual loss in patients with acquired immunodeficiency syndrome and cytomegalovirus retinitis. This syndrome was associated with immune recovery mediated by combination antiretroviral treatment including protease inhibitors. DESIGN: A case-control study at 2 university medical centers. PARTICIPANTS: One hundred thirty patients with acquired immunodeficiency syndrome and cytomegalovirus retinitis were examined at 2 medical centers for 15 months. In addition, the medical records of 509 patients examined at 1 center for 11 years before the initiation of protease inhibitor therapy were analyzed retrospectively. RESULTS: Five patients with symptomatic vitritis and papillitis with cystoid macular edema or epiretinal membrane formation were documented. In each patient there was inactive cytomegalovirus retinitis that had not caused visual decrease before the onset of inflammation. All patients had elevated CD4+ T lymphocyte levels (median increase, 86x10(6)/L [86 cells/mm3]) after combination treatment including protease inhibitors. Two patients with cystoid macular edema were treated with corticosteroids and had resolution of the cystoid macular edema and an increase in visual acuity without reactivation of the retinitis. Retrospective analysis failed to disclose similar patients with intraocular inflammation in the era before the introduction of protease inhibitors. CONCLUSIONS: This newly described syndrome of posterior segment inflammation related to cytomegalovirus retinitis is a cause of visual morbidity in patients with acquired immunodeficiency syndrome. It is associated with increased immune competence as a result of combined antiretroviral treatment with protease inhibitors and may be amenable to corticosteroid therapy without reactivation of retinitis.

Acute posterior multifocal placoid pigment epitheliopathy after acute group A streptococcal infection.

PURPOSE: We studied a case of acute posterior multifocal placoid pigment epitheliopathy in a 40-year-old man who had had an acute febrile illness. METHODS: The medical record was reviewed for clinical manifestations, course of disease, and laboratory findings, including results of fluorescein and indocyanine green angiography. RESULTS: The patient had the typical clinical course of acute posterior multifocal placoid pigment epitheliopathy with spontaneous resolution of posterior pole lesions and improvement in visual acuity from 20/60 to 20/20. The laboratory evaluation was remarkable for a rise in the anti-DNAse B antibody titer between initial and convalescent-phase serum samples, providing evidence of recent group A streptococcal infection. CONCLUSION: Although acute posterior multifocal placoid pigment epitheliopathy is often attributed to a postviral condition, this syndrome may also develop after an acute group A streptococcal infection.
