1/49. HSV-1--induced acute retinal necrosis syndrome presenting with severe inflammatory orbitopathy, proptosis, and optic nerve involvement.OBJECTIVE: To present a unique case in which orbital inflammation, proptosis, and optic neuritis were the initial symptoms of acute retinal necrosis (ARN). The clinical presentation of ARN, as well as the currently recommended diagnostic procedures and guidelines for medical treatment of ARN, are summarized. DESIGN: Interventional case report. TESTING: polymerase chain reaction (PCR) techniques were made on the vitreous for cytomegalovirus, Epstein-Barr virus, herpes simplex virus (HSV), varicella zoster virus, and toxoplasmosis. A full laboratory evaluation was made together with HLA-typing and serologic tests measuring convalescent titers for HSV and other micro-organisms. magnetic resonance imaging scan, computed tomography (CT) scan, and fluorescein angiographic examination were performed. The patient was treated with acyclovir and oral prednisone. MAIN OUTCOME MEASURES: The patient was evaluated for initial and final visual acuity and for degree of proptosis, periocular edema, and vitreitis. RESULTS: The first symptoms and signs of ARN were eye pain, headache, proptosis, and a swollen optic nerve on CT scan. Other than increased c-reactive protein, all blood samples were normal. PCR was positive for HSV-type I in two separate vitreous biopsies. The patient had the strongly ARN-related specificity HLA-DQ7. CONCLUSIONS: This is the first report of HSV-induced ARN presenting with inflammatory orbitopathy and optic neuritis. polymerase chain reaction for HSV-1 was positive more than 4 weeks after debut of symptoms, which is a new finding. The combination of severe vitreitis and retinal whitening, with or without proptosis, should alert the clinician to the possibility of herpes infection and treatment with intravenous acyclovir started promptly.- - - - - - - - - - ranking = 1keywords = cytomegalovirus (Clic here for more details about this article) |
2/49. Progressive outer retinal necrosis caused by herpes simplex virus type 1 in a patient with acquired immunodeficiency syndrome.OBJECTIVE/BACKGROUND: To identify the etiologic agent of rapidly progressive outer retinal necrosis (PORN) in a 32-year-old man with acquired immunodeficiency syndrome (AIDS), who had retinitis developed from cytomegalovirus (CMV). Multiple yellowish spots appeared in the deep retina without evidence of intraocular inflammation or retinal vasculitis, diagnosed clinically as PORN. death occurred after failure of multiple organs. DESIGN: Case report. methods: Both globes were taken at autopsy, fixed in formalin, and examined histopathologically and immunohistochemically to identify causative agents in the retinal lesions. MAIN OUTCOME MEASURE: immunohistochemistry. RESULTS: All layers of the retina were severely damaged and contained focal calcification. Cytomegalic inclusion bodies were found in cells in the damaged retina of the right eye. Immunohistochemical studies for herpesviruses revealed the presence of CMV antigens in the right retina at the posterior pole and herpes simplex virus type 1 (HSV-1)-specific antigen in the periphery of both retinas. No varicella-zoster virus (VZV) antigen was detected in either retina. CONCLUSIONS: PORN has been described as a variant of necrotizing herpetic retinopathy, occurring particularly in patients with AIDS. Although the etiologic agent has been reported to be VZV, HSV-1 can be an etiologic agent.- - - - - - - - - - ranking = 21.037935311719keywords = retinitis, cytomegalovirus (Clic here for more details about this article) |
3/49. Intravitreal antiviral injections as adjunctive therapy in the management of immunocompetent patients with necrotizing herpetic retinopathy.PURPOSE: To report the use of intravitreal antiviral injections as adjunctive therapy in the management of three immunocompetent patients with necrotizing herpetic retinopathy. METHOD: Case series. RESULTS: Three patients with necrotizing herpetic retinopathy received intravitreal antiviral injections for treatment of progressive retinitis, despite standard intravenous acyclovir therapy. The retinitis resolved and visual acuity improved after a minimum of 6 months of follow-up in each case. CONCLUSION: Intravitreal antiviral injections may be a safe and efficacious adjunctive therapy in the management of patients with necrotizing herpetic retinopathy.- - - - - - - - - - ranking = 40.075870623438keywords = retinitis (Clic here for more details about this article) |

5/49. Presumed acquired ocular toxoplasmosis in deer hunters.PURPOSE: To describe acquired ocular toxoplasmosis in deer hunters. methods AND RESULTS: The authors describe five young men presenting with flu-like symptoms followed by visual loss due to a unilateral, focal necrotizing retinitis. All five men gave a history of ingesting undercooked or uncooked venison. All five had elevated toxoplasma serology, and all five improved clinically with an antitoxoplasma regimen. CONCLUSION: In previously healthy young men, flu-like symptoms associated with visual loss and retinitis should prompt questioning about hunting and raw game meat ingestion, especially when toxoplasmosis is suspected.- - - - - - - - - - ranking = 40.075870623438keywords = retinitis (Clic here for more details about this article) |
6/49. Progressive outer retinal necrosis syndrome in a lymphoma patient with good visual outcome.PURPOSE: To report an hiv-negative lymphoma patient who developed progressive outer retinal necrosis syndrome and who had a good visual outcome after treatment with two-drug antiviral therapy and intravenous immunoglobulin. methods: Case report. RESULTS: A 43-year-old man with small lymphocytic lymphoma was diagnosed with progressive outer retinal necrosis in his left eye. Treatment was initiated with intravenous foscarnet and ganciclovir as well as intravenous gammaglobulin at a dose of 0.5 gm/kg per day for 5 days. On the second hospital day he was started on decadron 4 mg orally four times daily. No further posterior retinitis progression was observed despite severe immunosuppression. visual acuity remained stable at 20/30 with 10 months' follow-up. CONCLUSIONS: The benefit of using gammaglobulin in progressive outer retinal necrosis is unknown. Given the rapid improvement seen in this patient's retinitis, it may be reasonable to consider the use of gammaglobulin in other cases of infectious retinitis in immunocompromised patients.- - - - - - - - - - ranking = 60.113805935156keywords = retinitis (Clic here for more details about this article) |
7/49. Optic neuropathy and central retinal vascular obstruction as initial manifestations of acute retinal necrosis.BACKGROUND: The purpose of this brief communication is to alert ophthalmologists that optic neuropathy may herald acute retinal necrosis (ARN). CASE: A previously healthy 54-year-old man exhibited optic neuropathy as an initial presentation of ARN, 8 weeks after varicella-zoster dermatitis. OBSERVATIONS: Central retinal vascular obstruction developed subsequently in his left eye. Later, the classic presentation of ARN appeared in his contralateral eye. Systemic acyclovir therapy stopped the progression of retinitis and resulted in healing of retinal lesions in his right eye. CONCLUSIONS: This case suggests that optic neuropathy, especially with preceding herpetic dermatitis, should be suspected as the prodrome of ARN.- - - - - - - - - - ranking = 20.037935311719keywords = retinitis (Clic here for more details about this article) |
8/49. Acute retinal necrosis in children caused by herpes simplex virus.PURPOSE: To report the diagnosis, management, and outcome of acute retinal necrosis syndrome in children. METHOD: Case series of three consecutive children aged 11 years and younger who were diagnosed with acute retinal necrosis. In addition to full ocular and systemic examinations, the children underwent vitreous biopsy (patients 1 and 2) or aqueous tap (Patient 3) for polymerase chain reaction analysis. RESULTS: All patients had unilateral retinitis that was associated with preexisting chorioretinal scars, and two patients (patients 1 and 3) had concurrent extraocular central nervous system abnormalities. Intraocular herpes simplex virus was detected in all three children: Type 1 in Patient 1 and Type 2 in patients 2 and 3. In addition, all three children had a history of extraocular herpes simplex virus infection. CONCLUSIONS: retinitis associated with preexisting chorioretinal scars and detectable intraocular herpes simplex virus on polymerase chain reaction was common to all three children with acute retinal necrosis.- - - - - - - - - - ranking = 20.037935311719keywords = retinitis (Clic here for more details about this article) |
9/49. Progressive outer retinal necrosis and acute retinal necrosis in fellow eyes of a patient with acquired immunodeficiency syndrome.PURPOSE: To describe an unusual concurrence of acute retinal necrosis and progressive outer retinal necrosis in fellow eyes of a patient with acquired immunodeficiency syndrome (AIDS). methods: Interventional case report. In a 37-year-old man with AIDS and herpes zoster keratitis in the right eye, progressive outer retinal necrosis developed in the right eye and acute retinal necrosis developed in the left eye. RESULTS: Disparate presentations of retinitis persisted in each eye, and retinal detachment and vision loss ensued in both eyes despite antiviral therapy. CONCLUSION: Distinct features of acute retinal necrosis and progressive outer retinal necrosis do not necessarily reflect systemic factors, and they may be variant manifestations of the same underlying infection.- - - - - - - - - - ranking = 20.037935311719keywords = retinitis (Clic here for more details about this article) |
10/49. Aseptic meningitis and optic neuritis preceding varicella-zoster progressive outer retinal necrosis in a patient with AIDS.Varicella-Zoster Virus (VZV) is the second most common ocular pathogen in patients with hiv infection. VZV retinitis is estimated to occur in 0.6% of patients with hiv infection and may occur in one of two clinical syndromes. The first is the acute retinal necrosis syndrome, which also may be seen in immunocompetent hosts. The second clinical syndrome occurs in patients with CD4 cell counts typically < 50 x 10(6)/l and is termed progressive outer retinal necrosis. VZV retinitis has been reported to occur simultaneously with other VZV central nervous system manifestations such as encephalitis and myelitis in hiv-infected patients. In addition, VZV retrobulbar optic neuritis heralding VZV retinitis has recently been described in hiv-infected patients who had suffered a recent episode of dermatomal herpes zoster. Herein we report the case of an hiv-infected individual who presented with VZV meningitis and retrobulbar optic neuritis that preceded the onset of progressive outer retinal necrosis. We also review of the literature of seven additional reported cases of retrobulbar optic neuritis preceding the onset of VZV retinitis.- - - - - - - - - - ranking = 80.151741246875keywords = retinitis (Clic here for more details about this article) |
