Inflammation of the choroid in which the sensory retina becomes edematous and opaque. The inflammatory cells and exudate may burst through the sensory retina to cloud the vitreous body.
Infection caused by the protozoan parasite TOXOPLASMA in which there is extensive connective tissue proliferation, the retina surrounding the lesions remains normal, and the ocular media remain clear. Chorioretinitis may be associated with all forms of toxoplasmosis, but is usually a late sequel of congenital toxoplasmosis. The severe ocular lesions in infants may lead to blindness.
Inflammation in which both the anterior and posterior segments of the uvea are involved and a specific focus is not apparent. It is often severe and extensive and a serious threat to vision. Causes include systemic diseases such as tuberculosis, sarcoidosis, and syphilis, as well as malignancies. The intermediate segment of the eye is not involved.
Inflammation of the choroid as well as the retina and vitreous body. Some form of visual disturbance is usually present. The most important characteristics of posterior uveitis are vitreous opacities, choroiditis, and chorioretinitis.
A genus of parasitic nematodes whose organisms live and breed in skin and subcutaneous tissues. Onchocercal microfilariae may also be found in the urine, blood, or sputum.
Conditions which affect the structure or function of the pupil of the eye, including disorders of innervation to the pupillary constrictor or dilator muscles, and disorders of pupillary reflexes.

Inflammation of part or all of the uvea, the middle (vascular) tunic of the eye, and commonly involving the other tunics (sclera and cornea, and the retina). (Dorland, 27th ed)
Prenatal protozoal infection with TOXOPLASMA gondii which is associated with injury to the developing fetal nervous system. The severity of this condition is related to the stage of pregnancy during which the infection occurs; first trimester infections are associated with a greater degree of neurologic dysfunction. Clinical features include HYDROCEPHALUS; MICROCEPHALY; deafness; cerebral calcifications; SEIZURES; and psychomotor retardation. Signs of a systemic infection may also be present at birth, including fever, rash, and hepatosplenomegaly. (From Adams et al., Principles of Neurology, 6th ed, p735)
The space in the eye, filled with aqueous humor, bounded anteriorly by the cornea and a small portion of the sclera and posteriorly by a small portion of the ciliary body, the iris, and that part of the crystalline lens which presents through the pupil.

De novo lesions in presumed ocular histoplasmosis-like syndrome. (1/118)

Two patients with multifocal choroiditis similar or identical to POHS are presented. Colour photographs and fluorescein angiography document the occurrence of de novo lesions in the originally involved eye. The cases also demonstrate the development of new choroidal lesions within the originally involved eye, the early evolution of the "basic choroidal lesion", and the need for fluorescein angiography for visualizing the underlying choroidal lesion.  (+info)

New animal model for human ocular toxocariasis: ophthalmoscopic observation. (2/118)

BACKGROUND/AIMS: Although human ocular toxocariasis causes severe vision defect, little is known about its aetiology, diagnosis, and treatment. To develop a new animal model for human ocular toxocariasis, ophthalmological findings of fundi in Mongolian gerbils, Meriones unguiculatus, and BALB/c mice were investigated following infection with Toxocara canis. METHODS: Using an ophthalmoscope, which was specifically developed to observe the fundi of small animals, ocular changes of fundi of 20 gerbils and 11 mice were monitored after oral infection with embryonated eggs of T canis. RESULTS: Vitreous, choroidal, and retinal haemorrhages were consistently observed in Mongolian gerbils, but rarely in mice. Severe exudative lesions and vasculitis were often present in gerbils but not in mice. Migrating larvae were also frequently observed in gerbils. CONCLUSION: Mongolian gerbils are more appropriate animal model for human ocular toxocariasis than previously used experimental animal such as mice, guinea pigs, rabbits, and monkeys because of its high susceptibility of ocular infection.  (+info)

Detection of specific immunoglobulin E during maternal, fetal, and congenital toxoplasmosis. (3/118)

Toxoplasma immunoglobulin E (IgE) antibodies in 664 serum samples were evaluated by using an immunocapture method with a suspension of tachyzoites prepared in the laboratory in order to evaluate its usefulness in the diagnosis of acute Toxoplasma gondii infection during pregnancy, congenital infection, and progressive toxoplasmosis. IgE antibodies were never detected in sera from seronegative women, from patients with chronic toxoplasma infection, or from infants without congenital toxoplasmosis. In contrast, they were detected in 86.6% of patients with toxoplasmic seroconversion, and compared with IgA and IgM, the short kinetics of IgE was useful to date the infection precisely. For the diagnosis of congenital toxoplasmosis, specific IgE detected was less frequently than IgM or IgA (25 versus 67.3%), but its detection during follow-up of children may be interesting, reflecting an immunological rebound. Finally, IgE was detected early and persisted longer in progressive toxoplasmosis with cervical adenopathies, so it was also a good marker of the evolution of toxoplasma infection.  (+info)

Toxoplasma gondii infection induces gene expression and secretion of interleukin 1 (IL-1), IL-6, granulocyte-macrophage colony-stimulating factor, and intercellular adhesion molecule 1 by human retinal pigment epithelial cells. (4/118)

We have used human retinal pigment epithelial (HRPE) cultures to investigate the primary cellular responses of retinal resident cells to intracellular Toxoplasma gondii replication. At 4 days postinoculation, when all of the cells were infected, the secretion of interleukin 1beta (IL-1beta), IL-6, granulocyte-macrophage colony-stimulating factor (GM-CSF), and intercellular adhesion molecule 1 (ICAM-1) was augmented by 23-, 10-, 8-, and 5-fold, respectively, over the control. Northern and reverse transcriptase PCR analyses showed significant upregulation of steady-state levels of mRNA for IL-1beta, IL-6, GM-CSF, and ICAM-1. The secretion of these molecules by HRPE cells may play a critical immunoregulatory role in the pathophysiological processes associated with T. gondii-induced retinochoroiditis.  (+info)

Childhood blindness and visual loss: an assessment at two institutions including a "new" cause. (5/118)

PURPOSE: This study was initiated to investigate the causes of childhood blindness and visual impairment in the United States. We also sought a particular etiology--congenital lymphocytic choriomeningitis virus (LCMV)--which has been considered exceedingly rare, in a fixed target population of children, the severely mentally retarded. METHODS: We undertook a library-based study of the world literature to shed light on the causes of childhood blindness internationally and to put our data in context. We prospectively examined all consented children (159) at 2 institutions in the United States to determine their ocular status and the etiology of any visual loss present. One of the institutions is a school for the visually impaired (hereafter referred to as Location V), in which most of the students have normal mentation. The other is a home for severely mentally retarded, nonambulatory children (hereafter referred to as Location M). This institution was selected specifically to provide a sample of visual loss associated with severe retardation because the handful of cases of LCMV in the literature have been associated with severe central nervous system insults. Histories were obtained from records on site, and all children received a complete cyclopleged ophthalmic examination at their institution performed by the author. Patients at Location M with chorioretinal scars consistent with intrauterine infection (a possible sign of LCMV) had separate consents for blood drawing. Sera was obtained and sent for standard TORCHS titers, toxoplasmosis titers (Jack S. Remington, MD, Palo Alto, Calif), and ELISA testing for LCMV (Centers for Disease Control and Prevention, Atlanta, Ga). RESULTS: The diagnoses at Location V were varied and included retinopathy of prematurity (19.4%), optic atrophy (19.4%), retinitis pigmentosa (14.5%), optic nerve hypoplasia (12.9%), cataracts (8.1%), foveal hypoplasia (8.1%), persistent hyperplastic primary vitreous (4.8%), and microphthalmos (3.2%). The most common diagnosis at Location M was bilateral optic atrophy, which was found in 65% of the patients examined who had visual loss. Of these, the insults were most often congenital (42.6%), with birth trauma, prematurity, and genetics each responsible for about 15% of the optic atrophy. The second most common diagnosis was cortical visual impairment (24%), followed by chorioretinal scars (5%), which are strongly suggestive of intrauterine infection. Of 95 patients examined at Location M, 4 had chorioretinal scars. Two of these had dramatically elevated titers for LCMV, as did one of their mothers. One of the other 2 children died before serum could be drawn, and the fourth had negative titers for both TORCHS and LCMV. CONCLUSIONS: At both locations studied, visual loss was most often due to congenital insults, whether genetic or simply prenatal. The visual loss at Location V was twice as likely as that at Location M to be caused by a genetic disorder. The genetic disorders at Location V were more often isolated eye diseases, while those among the severely retarded at Location M were more generalized genetic disorders. Our study identified optic atrophy as a common diagnosis among the severely mentally retarded with vision loss, a finding that is supported by previous studies in other countries. In our population of severely retarded children, the target etiology of lymphocytic choriomeningitis virus was responsible for half the visual loss secondary to chorioretinitis from intrauterine infection. This is more common than would be predicted by the few cases previously described in the literature, and strongly suggests that LCMV may be a more common cause of visual loss than previously appreciated. We believe that serology for LCMV should be part of the workup for congenital chorioretinitis, especially if the TORCHS titers are negative, and that perhaps the mnemonic should be revised to "TORCHS + L." Childhood blindness and visual impairment are tragic and co  (+info)

Population based assessment of uveitis in an urban population in southern India. (6/118)

AIM: To assess the prevalence of active and inactive uveitis unrelated to previous surgery or trauma in an urban population in southern India. METHODS: As part of the Andhra Pradesh Eye Disease Study, 2522 subjects (85.4% of those eligible), a sample representative of the population of Hyderabad city in southern India, underwent interview and detailed dilated eye examination. Presence of sequelae of uveitis without current active inflammation was defined as inactive uveitis. RESULTS: Unequivocal evidence of active or inactive uveitis unrelated to previous surgery or trauma was present in 21 subjects, an age-sex adjusted prevalence of 0.73% (95% confidence interval (CI) 0.44-1.14%). Active uveitis was present in eight subjects, an age-sex adjusted prevalence of 0.37% (95% CI 0. 19-0.70), of which 0.06% was anterior, 0.25% intermediate, and 0.06% posterior. The 0.36% (95% CI 0.17-0.68%) prevalence of inactive uveitis included macular chorioretinitis scars (0.26%), anterior (0. 07%) and previous vasculitis involving the whole eye (0.03%). The prevalence of visual impairment due to uveitis of less than 6/18 in at least one eye was 0.27%, less than 6/60 in at least one eye was 0. 16%, and less than 6/60 in both eyes was 0.03%. CONCLUSION: These population based cross sectional data give an estimate of the prevalence of various types of uveitis in this urban population in India. Active or past uveitis that might need treatment at some stage was present in one of every 140 people in this population.  (+info)

Rapid progressive subacute sclerosing panencephalitis in a 2-year-old child with congenital athyreosis. (7/118)

We present the unique case of a 2-year-old girl with congenital athyreosis who acquired primary measles virus infection at the age of 18 months, coincidentally with an Epstein-Barr virus infection. First neurologic symptoms of subacute sclerosing panencephalitis appeared 5 months later, and the girl died within 6 months after a rapid progressive illness. Factors possibly predisposing to this extraordinary disease course-primary measles virus infection at an early age and lack of evidence for immunodeficiency-are discussed.  (+info)

Effect of Fas and Fas ligand deficiency in resistance of C57BL/6 mice to HSV-1 keratitis and chorioretinitis. (8/118)

PURPOSE: To investigate the effect of Fas and Fas ligand (FasL) deficiency on the development of herpes stromal keratitis and on the von Szily model of herpes retinitis in C57BL/6 mice, which are ordinarily resistant to development of both of these herpetic diseases. METHODS: Anterior chamber inoculation of the right eye of each mouse with various titers of HSV-1 (KOS strain) was performed. Both eyes of each mouse were enucleated on postinoculation day 15 and processed for histopathologic examination. HSV-1 was inoculated into one cornea of other mice, and the severity of stromal keratitis was scored. RESULTS: Contralateral destructive chorioretinitis developed in susceptible Balb/cByj mice (19/23); ipsilateral chorioretinitis did not occur (0/23). Stromal keratitis developed in susceptible C.AL-20 mice (15/16). None of the C57BL/6 (0/10 for keratitis or 0/20 for retinitis) developed inflammation. Neither did B6.SMN.C3H.gld (FasL deficient; 0/12 or 0/28) or B6.MRL.lpr (Fas deficient; 0/11 or 0/34) mice (keratitis or contralateral chorioretinitis). Minimal scattering of inflammatory cells in the contralateral retina but not destructive chorioretinitis was observed in two C57BL/6, three B6.SMN.C3H.gld, and five B6.MRL.lpr mice. Few inflammatory cells were also found in the ipsilateral vitreous and vitreoretinal interface (but not destructive chorioretinitis) of all C57BL/6, two gld, and three lpr mice. CONCLUSIONS: Immune dysregulation secondary to deficiency in Fas or FasL system does not influence the resistance of the C57BL/6 mice to develop herpes simplex keratitis or destructive herpes simplex chorioretinitis.  (+info)

Toxoplasma chorioretinitis, more simply known as ocular toxoplasmosis, is probably the most common cause of infections in the back of the eye (posterior segment) worldwide. The causitive agent is Toxoplasma gondii, and in the United States, most cases are acquired congenitally. The most common symptom is decreased visual acuity in one eye. The diagnosis is made by examination of the eye, using ophthalmoscopy. Sometimes serologic testing is used to rule out the disease, but due to high rates of false positives, serologies are not diagnostic of toxoplasmic retinitis. If vision is not compromised, treatment may not be necessary. When vision is affected or threatened, treatment consists of pyrimethamine, sulfadiazine, and folinic acid for 4-6 weeks. Prednisone is sometimes used to decrease inflammation. A unilateral decrease in visual acuity is the most common symptom of toxoplasmic retinitis. Under ophthalmic examination, toxoplasmic chorioretinitis classically appears as a focal, white retinitis ...

Endogenous fungal endophthalmitis is a serious vision-threatening condition that occurs in immunosuppressed patients with candidemia. We report a complicated case of Candida albicans chorioretinitis that progressed to endophthalmitis. The patient required intravitreal and systemic anti-fungal medications with pars plana vitrectomy for successful treatment. Multimodal imaging using fundus photography, fluorescein angiography, spectral domain optical coherence tomography, and fundus autofluorescence was obtained throughout treatment. These modalities localized the Candida infection in the choroid, penetrating Bruchs membrane, the retinal pigment epithelium, and the retina to enter the vitreous cavity. This infectious route resulted in loss of the retinal pigment epithelium, photoreceptors, and outer retinal layers, with scar formation that resulted in vision loss and increased future risk of choroidal neovascular membranes. Multimodal imaging of C. albicans chorioretinitis allows for accurate diagnosis,

Purpose : Purpose: Birdshot chorioretinopathy (BSCR) is an inflammatory white dot syndrome, affecting the retina and choroid, with a chronic, insidious course. OCT angiography (OCTA) is a non-invasive imaging modality that provides details of the retinal capillary plexuses in 3-dimensions. The purpose of this study was to quantify changes in retinal vascular microstructure of patients with BSCR compared with controls and evaluate changes with respect to disease duration. Methods : Methods: 16 eyes of 8 patients with BSCR were compared with 13 eyes of 7 age-matched controls, using 3 x 3 mm obtained from OCTA. The vascular density (VD), avascular region (AvR) and gray zone (GZ) within superficial vascular plexus (SVP) and deep vascular plexus (DVP) were analyzed as was the blood vessel tortuosity and foveal avascular zone (FAZ) area within SVP. Correlation of these parameters with disease duration was performed. Results : Results: There were 6 female and 2 male BSCR patients with an average age of ...
A 28 year-old man presented with sudden visual loss in his left eye. Best-corrected visual acuity was 20/20 in the right eye and 20/400 in the left eye. Fundus examination showed a whitish retinal lesion of the superotemporal quadrant involving the supero-temporal retinal vein branch with mild vitritis. Fluorescein angiography confirmed active retinochoroidal inflammation (black arrow) with delayed filling and tortuosity of the involved vein (white arrow); capillary dilatation was present within the affected drainage area (white arrowhead) with dye leakage in late frames, resulting in cystoid macular edema (black arrowhead) which was sectorial on macular OCT (optical coherence tomography) (star). Serological tests, after anterior chamber puncture, confirmed local production of specific anti toxoplasma antibodies. The patient was treated with clindamycin 150 mg four times a day and prednisolone 60 mg daily. After 6 weeks of antiparasitic therapy the lesion became inactive and visual acuity improved.
Abstract: : Purpose: Eosinophilic enteritis (EE) is defined by the presence of intestinal symptoms and eosinophilic infiltration, traditionally in the absence of extra-intestinal organ involvement. Peripheral blood eosinophilia is found in the majority of patients. EE is common in Australia and is often associated with infection by the common dog hookworm Ancylostoma caninum, although other worms have been identified. We hereby describe a case of unusual unilateral chorioretinitis and subretinal neovascularization in a young boy with eosinophilic enteritis. Methods: Report of a single, observational case. Results: A 10-year-old Caucasian boy (dog-owner) presented with unilateral, painless, subacute loss of vision. Two months previously, visual acuity (VA) in the left eye was correctable to 20/30. On presentation, VA was 20/20 OD and counting finger (CF) OS. Anterior segments were normal. The right fundus was unremarkable.

Birdshot chorioretinitis (BSCR) is a rare ocular inflammatory disorder associated with HLA-A29 and characterized by bilateral choroidal lesions, vitritis, macular edema, and retinal vasculitis. Ocular inflammation associated with HLA-B27 is typically a recurrent, unilateral, acute anterior uveitis (AAU) that is frequently associated with ankylosing spondylitis (AS). To date, there are no reports of patients with both HLA-A29-positive BSCR and HLA-B27 AAU/AS in the English literature. A 50-year-old man with a history of bilateral anterior uveitis, vitritis, retinal vasculitis, and cream-colored depigmented oval choroidal lesions was found to be HLA-A29 and HLA-B27 positive. His lumbar spine and sacroiliac joint films revealed fusion of the spine, known as `bamboo spine compatible with the diagnosis of ankylosing spondyloarthropathy. He had chronic ocular inflammation that was difficult to control with systemic steroids and immunomodulatory agents. This is the only report of a patient with both HLA-A29

Toxoplasmic chorioretinitis may be diagnosed as a congenital or postnatally acquired disease due to primary infection or reactivation of latent infection. Toxoplasmosis causes an acute focal retinitis in which the hallmark is a thickened cream-colored retina accompanied by an overlying intense vitreal inflammatory reaction (headlight in the fog appearance). Recurrent lesions are usually seen at the borders of chorioretinal scars (Fig. 1C). Primary ocular infections are less common than reactivation of old lesions. Based on seroprevalence data, the overall incidence of infection with Toxoplasma gondii ranges from 22.5% in the United States to 75% in El Salvador. In immunocompetent individuals, the primary infection is usually asymptomatic, although a small percentage of individuals will develop chorioretinitis, lymphadenitis, myocarditis, or polymyositis. An unfavorable, life-threatening course of toxoplasmosis would be expected only in persons with impaired T-cell-mediated immunity, such as ...
Syphilis is reemerging globally, particularly in association with HIV coinfection. The clinical presentations of ocular syphilis include scleritis; anterior, intermediate or posterior uveitis; and even optic neuritis. Patients may also experience mucocutaneous and CNS symptoms A classic manifestation of syphilis in patients with AIDS is unilateral or bilateral, pale-yellow, placoid retinal lesions that preferentially involve the macula (syphilitic posterior placoid chorioretinitis). Patients with AIDS may also present with discrete creamy yellow superficial retinal precipitates overlying areas of syphilitic retinitis as a very suggestive finding, although they can occur regardless of HIV status. In patients with AIDS, vitritis without chorioretinitis can be the first manifestation of syphilis. For discussion of other manifestations, refer to Chapter 10.. The course of syphilis may be more aggressive in HIV-infected patients. These patients require treatment with 18-24 million units of ...

Background Congenital toxoplasmosis is associated with severe complications. two trimesters, acute toxoplasmosis contamination is usually characterised by septic symptoms, hepatosplenomegaly, thrombocytopenia, hyperbilirubinemia, and central nervous system infections [1, 7, 8] The latter typically present with encephalitis in combination with retinochorioiditis, hydrocephalus, intracranial calcifications, microphthalmia, and microcephaly, as well as calcifying necroses developing from reactive inflammations, to the point of spontaneous abortion [9]. In contrast, the majority of fetuses infected during the third trimester lack pathological findings at birth (70C90?%) [10, 11]. However, in 30C70?% of offspring with clinical abnormalities, those abnormalities are not detected in the beginning; these children typically have chorioretinitis, hearing loss, and mental retardation later in life [12, 13]. infections are mostly asymptomatic in adults and immunocompetent individuals; consequently, acute ...

Toxoplasma gondii (T. gondii) and Plasmodium spp. cause toxoplasmosis and malaria respectively. Malaria affects 200 million people worldwide and kills almost half a million people every year. The biggest toll is on children of sub-Saharan Africa who suffer from deadly complications such as cerebral malaria. Toxoplasmosis poses serious risk in fetuses if contracted during pregnancy and T. gondii infection may lead to chorioretinitis or encephalitis in immunocompromised individuals. Toxoplasmosis is also a veterinarian issue with a major economical impact for the sheep industry ...
This is primarily a disorder of skin, teeth, hair, and the central nervous system but 35% of patients have important ocular features. The iris is variably atrophic and has pigmentary anomalies often with posterior synechiae. Nystagmus, strabismus, and limited vision are often present. The majority (up to 90%) of individuals have significant retinal disease. The retinal vascular pattern is anomalous with tortuosity in some areas and absence of vessels in others. Preretinal fibrosis and retinal detachments may suggest the presence of a retinoblastoma. Cataracts are common in patients who have a retinal detachment and some patients have microphthalmia. The retinal pigment epithelium is often abnormal with various-sized patches of sharply demarcated depigmentation. Cases with uveitis, papillitis and chorioretinitis have been observed and it has been suggested that the observed retinal and choroidal changes result from prior inflammatory disease, perhaps even occurring in utero. There is a great deal ...

PATIENT PRESENTATION A 7-month-old male child is brought to a physical therapist to be evaluated for a delay in motor skills acquisition. According to parental report, he has been slower to achieve motor milestones than his siblings. He has recently begun rolling from supine to prone and prone to supine and reportedly is beginning to sit momentarily. He was diagnosed with chorioretinitis shortly after birth which was successfully treated with antibiotics and steroids, although he continues to demonstrate mild photosensitivity. Parents report that he had seizures in the first few weeks of life that are well controlled on his current medication. Prenatal maternal history is positive for mild flu-like symptoms in the second trimester that went unreported.. Upon physical examination, the infant plays in supine, while holding a small toy with both hands. He rolls to prone in both directions to secure a toy held out of reach. He is vocally responsive to his parents and the examiner. He smiles and ...

Birdshot uveitis is a rare sight-threatening condition in which the bodys immune system attacks the retina and the choroid - two critical structures in the eye.. One of the major challenges in caring for people with birdshot is how difficult it is to tell when the condition is actively causing inflammation. There is no widely available, sensitive way to measure this, which can lead to over-treatment or under-treatment, both of which can cause problems.. The team has demonstrated that the light-based imaging device known as optical coherence tomography (OCT) can be used outside its usual field of action to detect changes in the retina and choroid in birdshot. It can even pick up changes in the vitreous jelly which fills the middle of the eye.. In this project they are using these imaging techniques to study how these features change over time and to assess how good this method could be for detecting flare-ups of disease. They believe that this approach will provide a patient-friendly way of ...

Objective. To perform an evidence-based review of treatments for Toxoplasma retinochoroiditis (TRC). Methods. A systematic literature search was performed using the PubMed database and the key phrase ocular toxoplasmosis treatment and the filter for controlled clinical trial and randomized clinical trial as well as OVID medline (1946 to May week 2 2014) using the keyword ocular toxoplasmosis. The included studies were used to evaluate the various treatment modalities of TRC. Results. The electronic search yielded a total of 974 publications of which 44 reported on the treatment of ocular toxoplasmosis. There were 9 randomized controlled studies and an additional 3 comparative studies on the treatment of acute TRC with systemic or intravitreous antibiotics or on reducing the recurrences of TRC. Endpoints of studies included visual acuity improvement, inflammatory response, lesion size changes, recurrences of lesions, and adverse effects of medications. Conclusions. There was conflicting ...

Clinical presentation: A 65-year-old diabetic man with a history of fever of unknown origin two weeks earlier complained of sudden decreased vision in the left eye. The patient was diagnosed with bilateral West Nile virus (WNV) chorioretinitis associated with occlusive retinal vasculitis in the left eye. He was evaluated using Swept-source optical coherence tomography angiography (SS OCTA). Imaging findings: SSOCTA of the left eye showed extensive well-delineated hypointense greyish areas of retinal capillary hypoperfusion and perifoveal capillary arcade disruption in the superficial capillary plexus, and larger greyish areas of capillary hypoperfusion, capillary rarefaction, and diffuse capillary network attenuation and disorganization in the deep ...
Cytomegalovirus retinitis commonly presents in immunocompromised lymphocytopenic patients, mainly in patients with AIDS. Occurances of CMV retinitis in immunocompetent patients although rare, have been described [9].. This report presents a case of bilateral CMV retinitis in an HIV negative patient with non-Hodgkins lymphoma who had a normal lymphocyte count. Intraocular inflammation of CMV aetiology occurred despite oral prophylaxis with valganciclovir. Similar cases have been published, where valganciclovir prophylaxis or ganciclovir/valganciclovir treatment were unable to prevent CMV retinitis because of drug resistance [10, 11].. It is critical to differentiate lymphomatous chorioretinal infiltration from opportunistic CMV infection in order to obtain an accurate diagnosis and initiate effective treatment in patients with non-Hodgkins lymphoma. It is well known that the differential diagnosis of such cases should also include fulminant toxoplasmic chorioretinitis, mycotic endophthalmitis, ...
Abstract: Purpose: To investigate whether recurrence rates of ocular toxoplasmosis are higher during pregnancy among women of childbearing age.Design: Retrospective longitudinal cohort study.Methods: We reviewed medical records of all women seen at a university eye clinic (Utrecht, Netherlands) during episodes of active toxoplasmic retinochoroiditis that occurred while the women were of childbearing age (16-42 years). Each woman was sent a questionnaire requesting information regarding all pregnancies and episodes of ocular toxoplasmosis, whether or not episodes were observed at the eye clinic. Conditional fixed-effects Poisson regression was used to model incident rate ratios of recurrence during pregnant versus non-pregnant intervals, adjusted (Read more...) Full Story →. ...
Bilateral macular hemorrhage is a rare ocular finding and to the best of our knowledge, this is the first report of such hemorrhages as a presentation of drug-induced anemia. We describe the case of a 14-year-old Caucasian boy who presented with a toxoplasmic retinochoroiditis and was treated with sulfadiazine and pyrimethamine. Three months later, he presented with a bilateral macular hemorrhage as a complication of a toxic induced anemia. Our patient presented with toxic anemia secondary to the treatment of a very common disease, ocular toxoplasmosis. Prophylactic use of folinic acid could prevent such complications but in many cases, it is not prescribed owing to its cost or is mistakenly substituted with folic acid, which does not present as a valid substitute.
Abstract In 1977, an outbreak of toxoplasmosis occurred among 37 persons associated with exposure to an indoor horse arena. Cat feces containing the organism were most likely stirred up when horses ran on the dirt floor, and were inhaled or ingested by riders and observers. After 25 or more years, we attempted to locate persons from the outbreak and offer them an eye examination. Of the 37 persons in the outbreak, 18 (49%) were located; four had died, and the remaining 14 agreed to an examination. Among the 14 persons examined, three (21%) were found to have lesions typical of toxoplasmic retinochoroiditis. If these three persons were the only ones with ocular disease among the 37 persons in the outbreak, the disease rate would still be high (8%). As a result of exposure to Toxoplasma gondii during this outbreak, a relatively high percentage of persons developed ocular disease.
A combination of pyrimethamine and sulfadiazine plus folinic acid should be administered for 1 year. Steroids are indicated in the presence of infalmmatory lesions such as chorioretinitis involving macula, CSF protein above 2 g/dl at birth or a generalized infection ...
It has been 100 years since Toxoplasma gondii was initially described in Tunis by Nicolle and Manceaux (1908) in the tissues of the gundi (Ctenodoactylus gundi) and in Brazil by Splendore (1908) in the tissues of a rabbit. Toxoplasma gondii is a ubiquitous, Apicomplexan parasite of warm-blooded animals that can cause several clinical syndromes including encephalitis, chorioretinitis, congenital infection and neonatal mortality. Fifteen years after the description of T. gondii by Nicolle and Manceaux a fatal case of toxoplasmosis in a child was reported by Janků. In 1939 Wolf, Cowen and Paige were the first to conclusively identify T. gondii as a cause of human disease. This review examines the clinical manifestations of infection with T. gondii and the history of the discovery of these manifestations ...

N2 - Mitogen-activated protein kinase (MAPK) pathways are major signal transduction systems by which eukaryotic cells convert environmental cues to intracellular events, such as cell proliferation and differentiation. Toxoplasma gondii is an obligate intracellular protozoan that is both a human and animal pathogen. This Apicomplexan causes significant morbidity and mortality in immune-competent and immune-compromised hosts. In humans, the most common manifestations of T. gondii infections are chorioretinitis in congenital infection and encephalitis in immune-compromised patients, such as patients with advanced AIDS. We have identified a T. gondii homolog of the MAPK family that we have called TgMAPK2. ...

Raster scanning spectral domain optical coherence tomography (SD-OCT) enables realistic three-dimensional (3D) imaging of macular disease. This approach allows the clinician to investigate the diagnostic situation in detail before and during pharmacological or surgical intervention. This study demonstrates the clinical potential of SD-OCT in chorioretinal disease. Selected datasets are presented to visualize typical morphologic findings, which are identified in more than 2700 patients. Scans are presented as online assessable 3D-models. Clinically relevant structures are visualized in macular disease and highlight the importance of precise imaging, which clearly is a clinical necessity to plan and indicate modern therapeutic strategies for our patients.. ©2009 Optical Society of America.
