1/39. cytomegalovirus retinitis in the era of highly active antiretroviral therapy.A number of striking changes have occurred recently in the presentation and course of cytomegalovirus (CMV) retinitis in patients with acquired immunodeficiency syndrome (AIDS) who are receiving highly active antiretroviral therapy (HAART). Before the use of HAART, CMV retinitis was the most common intraocular infection in patients with AIDS, occurring in up to 40% of patients, typically when CD4 cell counts have decreased to less than 0.10 x 10(9)/L. By studying CMV retinitis, clinicians can investigate whether the rejuvenated immune system that results from HAART can effectively control opportunistic infections in patients with AIDS. In some patients, retinitis has not progressed when specific anti-CMV therapy was discontinued, but a number of patients have developed substantial intraocular inflammation, which has resulted in decreased visual acuity. Anterior uveitis, cataract, vitritis, cystoid macular edema, epiretinal membrane, and disc edema may occur in patients with CMV retinitis who have experienced HAART-associated elevation in CD4 cell counts. Since immune recovery uveitis does not occur in eyes without CMV retinitis, the ocular inflammation appears to be related to the CMV infection. Anti-CMV maintenance therapy likely can be safely discontinued in some patients with CMV retinitis if CD4 cell counts are stable or increasing and have been higher than 0.10 x 10(9)/L for at least 3 months. Immune recovery in patients receiving HAART has been effective in controlling opportunistic infections, but it may also result in intraocular inflammation, which can have adverse effects on the eye.- - - - - - - - - - ranking = 1keywords = retinitis, cytomegalovirus (Clic here for more details about this article) |
2/39. Exudative retinal detachment and retinitis associated with acquired syphilitic uveitis.PURPOSE: To describe three cases of exudative retinal detachment and focal retinitis associated with acquired syphilitic uveitis. methods: Three patients who were referred for evaluation of uveitis were examined. Slit-lamp examination, ophthalmoscopy, B-scan ultrasonography, fundus photography, and fluorescein angiography were performed before and after therapy. RESULTS: Each patient had uveitis with exudative retinal detachment, periphlebitis, and focal retinitis. Laboratory testing (fluorescent treponemal antibody absorption) revealed positive serology for active syphilis in all cases. Human immunodeficiency virus antibody testing was negative in all patients. retinal detachment resolved in all cases after treatment with intravenous penicillin. Despite resolution of subretinal fluid, visual acuity remained poor in eyes in which the macula was detached. CONCLUSION: Syphilis is a cause of exudative retinal detachment. Antibiotic therapy can lead to retinal reattachment. Early recognition and treatment may prevent severe vision loss.- - - - - - - - - - ranking = 0.53715634871075keywords = retinitis (Clic here for more details about this article) |
3/39. Long-term posterior and anterior segment complications of immune recovery uveitis associated with cytomegalovirus retinitis.PURPOSE: To identify and describe long-term posterior and anterior segment complications of immune recovery uveitis in patients with inactive cytomegalovirus retinitis who are undergoing highly active antiretroviral therapy-mediated recovery of immune function.methods: A prospective cohort study at a university medical center. Twenty-nine eyes of 21 patients with immune recovery uveitis and inactive cytomegalovirus retinitis were followed for 14.5 to 116 weeks (median, 43 weeks) after diagnosis of immune recovery uveitis. RESULTS: Nine eyes of nine patients developed visually important complications involving the posterior segment, anterior segment, or a combination of both. Posterior segment complications included severe proliferative vitreoretinopathy in three eyes and spontaneous vitreous hemorrhage from avulsion of a blood vessel secondary to contraction of the inflamed vitreous in one eye. Proliferative vitreoretinopathy recurred in all cases after surgery, severely compromising the visual outcome. Anterior segment complications included posterior subcapsular cataracts with vision decrease in five eyes and persistent anterior chamber inflammation after cataract extraction, resulting in posterior synechiae and large visually important lens deposits in three eyes.CONCLUSION: Persistent inflammation in immune recovery uveitis may lead to vision-threatening complications, such as proliferative vitreoretinopathy, posterior subcapsular cataracts, and severe postoperative inflammation. Immune recovery uveitis is a chronic inflammatory syndrome that may result in complications months to years after the onset of inflammation.- - - - - - - - - - ranking = 3.6640097186678keywords = cytomegalovirus retinitis, retinitis, cytomegalovirus (Clic here for more details about this article) |
4/39. fluocinolone acetonide sustained drug delivery device to treat severe uveitis.PURPOSE: Uveitis is often a chronic disease requiring long-term medical therapy. In this report, we describe a pilot safety and efficacy trial of a novel sustained drug delivery system containing fluocinolone acetonide to treat patients with severe uveitis. DESIGN: Prospective, noncomparative, interventional case series PARTICIPANTS: patients with severe uveitis. methods: Sustained drug delivery devices designed to release fluocinolone acetonide for at least 2.5 years were implanted through the pars plana into the vitreous cavity of seven eyes of five patients. All patients had severe uveitis not well controlled with, or intolerant to, repeated periocular corticosteroid injections, systemic corticosteroids, nonsteroidal immunosuppressive agents, or a combination thereof at the time of device implantation. Before device implantation, patients underwent complete evaluation including history, ophthalmologic examination, fluorescein angiography, visual field testing, and electroretinography. After surgery, patients were reexamined at 1 week, 2 weeks, 4 weeks, and at 1- to 3-month intervals. visual fields, electroretinograms, and fluorescein angiography were repeated at 3- to 6-month intervals. MAIN OUTCOME MEASURES: Preoperative and postoperative visual acuity, ocular inflammation, anti-inflammatory medication use, and intraocular pressure. RESULTS: patients had a diagnosis of Behcet's syndrome (two eyes), or idiopathic panuveitis (five eyes, including two with necrotizing retinitis, two with progressive chorioretinitis, and one with iridocyclitis and intermediate uveitis). patients were observed an average of 10 months (range, 5-19 months). All eyes had stabilized or improved visual acuity after device implantation, and four of seven eyes had an improvement of three lines or more. The mean initial visual acuity, measured by Snellen chart, was 20/207, and the mean final visual acuity was 20/57 (P = 0.02). After surgery, at the final visit, no eye had clinically detectable inflammation, and all seven eyes had a marked reduction in systemic, topical, and periocular anti-inflammatory medication use. Four eyes had increased intraocular pressure 6 weeks to 6 months after device implantation. intraocular pressure has been controlled on topical medications. No patient experienced intraoperative complications. CONCLUSIONS: A fluocinolone acetonide sustained drug delivery device is a promising new therapy for the treatment of severe uveitis. intraocular pressure must be carefully monitored long after device implantation. Based on these data, a randomized study of a larger group of patients is warranted.- - - - - - - - - - ranking = 0.17905211623692keywords = retinitis (Clic here for more details about this article) |
5/39. Multiple arterial ectasias in patients with sarcoidosis and uveitis.PURPOSE: To describe and evaluate the cause of a clinical entity characterized by bilateral intraocular inflammation, multiple arterial ectasias including beading, macroaneurysms, comma-like ectasias and kinking, with vasculitis, staining of the optic disk and multiple peripheral round punched-out hypopigmented chorioretinal scars in elderly patients. The formation and the course of the arterial ectasias is analyzed. methods: Seven patients with this syndrome were evaluated by clinical examination, fluorescein angiography, and systemic investigations. RESULTS: Three of the seven patients had a biopsy characteristic of sarcoidosis, two others showed positive bronchoalveolar lavage, as well as other analyses and tests suggesting sarcoidosis, and two showed other findings suggestive of sarcoidosis. The patients were all over 60 years of age and had arterial hypertension. In two patients, an arterial ectasia developed at the site of previous focal inflammation. The macroaneurysms either remained unchanged, became comma-like ectasias, arterial kinks, or completely vanished. CONCLUSION: Elderly patients with multiple arterial ectasias, uveitis, disk staining, and peripheral chorioretinitis should be thoroughly investigated for sarcoidosis. We suggest that sarcoidosis may cause some degree of arteritis, which may weaken the arterial wall, with resulting ectasia. Arterial hypertension may play a role in the formation of the ectasias by increasing the pressure on the arterial wall weakened by inflammation.- - - - - - - - - - ranking = 0.089526058118458keywords = retinitis (Clic here for more details about this article) |
6/39. Simultaneous occurrence of 2 hiv-related immunereconstitution diseases after initiation of highly active antiretroviral therapy.The case of a 44-y-old woman with hiv infection and cytomegalovirus retinitis in whom antiretroviral therapy (HAART) revealed pulmonary cryptococcosis is presented. Pulmonary cryptococcosis occurred simultaneously with immune recovery uveitis after starting HAART, showing that complex clinical pictures may arise from immunreconstitution diseases.- - - - - - - - - - ranking = 0.61066828644463keywords = cytomegalovirus retinitis, retinitis, cytomegalovirus (Clic here for more details about this article) |
7/39. Presumed choroidal atypical tuberculosis superinfected with cytomegalovirus retinitis in an acquired immunodeficiency syndrome patient: a case report.BACKGROUND: To report an unusual case of multifocal choroidopathy with uveitis and cytomegalovirus (CMV) retinitis in a patient with acquired immunodeficiency syndrome (AIDS) after initially presenting with pulmonary tuberculosis (mycobacterium kansasii). CASE: Slit-lamp biomicroscopy and indirect ophthalmoscopic examination were done. Vitreous biopsy, pars plana vitrectomy, and retinal biopsy were performed. Computer tomography scan, magnetic resonance imaging and biopsy of the brain were also carried out. OBSERVATIONS: Multiple yellowish-white, round, slightly elevated subretinal pigment epithelium lesions were noted in areas devoid of the atrophic retina of previous CMV infection. Anterior uveitis and vitritis were also noted. Vitreous, retina, and brain biopsy did not offer any clue for diagnosis. The visual acuity improved later, along with recovered immunity under the anti-tuberculosis medications and the cocktail therapy for AIDS. CONCLUSIONS: Combined CMV retinitis and atypical tuberculosis chorioretinitis, although rare, can develop in the patients with AIDS. Systemic dissemination of atypical tuberculosis infection should be responsible for the choroidopathy in this patient.- - - - - - - - - - ranking = 2.7264646808308keywords = cytomegalovirus retinitis, retinitis, cytomegalovirus (Clic here for more details about this article) |
8/39. Reactivation of CMV retinitis after treatment with subtenon corticosteroids for immune recovery uveitis in a patient with AIDS.We present the case of an hiv-infected patient who developed reactivation of CMV retinitis after a local steroid injection for the treatment of immune recovery uveitis. He responded promptly to reinduction with ganciclovir and recovered. To our knowledge this is the first case of CMV retinitis reactivation in an hiv-infected patient receiving steroids for immune recovery uveitis.- - - - - - - - - - ranking = 0.53715634871075keywords = retinitis (Clic here for more details about this article) |
9/39. Extensive retinal neovascularization as a late finding in human immunodeficiency virus-infected patients with immune recovery uveitis.Sixteen human immunodeficiency virus (hiv)-infected patients with inactive cytomegalovirus (CMV) retinitis who had discontinued systemic anti-CMV therapy while receiving highly active antiretroviral therapy (HAART) were prospectively observed. Fifteen patients developed immune recovery uveitis (IRU); 3 of the patients developed extensive retinal neovascularization, 1 of whom required vitrectomy for recurrent vitreous hemorrhages. These late complications indicate a need for continued ophthalmologic follow-up of hiv-infected patients who have a history of CMV retinitis, even for individuals who have not required anti-CMV therapy for >4 years.- - - - - - - - - - ranking = 0.19426547693388keywords = retinitis, cytomegalovirus (Clic here for more details about this article) |
10/39. Ocular syphilis: the new epidemic.AIM: To present the clinical presentation, diagnosis, and management of syphilitic uveitis in the context of an epidemic of syphilis in the UK. METHOD: Retrospective clinical case series. RESULTS: Six new cases of syphilitic uveitis presented to the Manchester Uveitis Clinic in 2004, after a 15-fold increase in the incidence of syphilis in the UK, including 615 cases in Greater Manchester in the 5 years to 2004. Four cases had secondary syphilis, two had latent disease, two had no rash, and two were hiv positive. Ocular involvement included anterior or panuveitis, retinitis, retinal vasculitis, and papillitis. All resolved on treatment including intramuscular procaine penicillin g with oral probenecid. CONCLUSIONS: Syphilis is much more common recently and syphilitic uveitis should be considered in all patients with rash and/or headache, where there is retinitis and/or retinal vasculitis, or in any uveitis of uncertain origin. Treatment is that of neurosyphilis.- - - - - - - - - - ranking = 0.17905211623692keywords = retinitis (Clic here for more details about this article) |
