1/60. The ocular manifestations of congenital infection: a study of the early effect and long-term outcome of maternally transmitted rubella and toxoplasmosis.PURPOSE: To study the spectrum of adverse ocular effects which result from maternally transmitted rubella and toxoplasma infection; further, to record the long-term visual and neurodevelopmental outcomes of these 2 major causes of fetal infection. STUDY DESIGN AND patients: A series of 55 patients with congenital infection have been studied prospectively on a long-term basis. The study group included a cohort of 34 cases with congenital rubella syndrome demonstrated by virus isolation, and 21 cases with a clinical diagnosis of congenital toxoplasmosis and serologic confirmation. All patients had specific disease-related ocular defects. Rubella patients were first identified during or following the last major rubella epidemic in 1963-1964, and some have been followed serially since that time. A separate study group of representative toxoplasmosis patients presented for examination and diagnosis at varying time periods between 1967 and 1991. OBSERVATIONS AND RESULTS: This study confirms that a broad spectrum of fetal injury may result from intrauterine infection and that both persistent and delayed-onset effects may continue or occur as late as 30 years after original infection. Many factors contribute to the varied outcome of prenatal infection, the 2 most important being the presence of maternal immunity during early gestation and the stage of gestation during which fetal exposure occurs in a nonimmune mother. RUBELLA: As a criteria of inclusion, all 34 rubella patients in this study exhibited one or more ocular defects at the time of birth or in the immediate neonatal period. Cataracts were present in 29 (85%) of the 34, of which 21 (63%) were bilateral. Microphthalmia, the next most frequent defect, was present in 28 (82%) of the 34 infants and was bilateral in 22 (65%). glaucoma was recorded in 11 cases (29%) and presented either as a transient occurrence with early cloudy cornea in microphthalmic eyes (4 patients), as the infantile type with progressive buphthalmos (1 patient), or as a later-onset, aphakic glaucoma many months or years following cataract aspiration in 11 eyes of 6 patients. Rubella retinopathy was present in the majority of patients, although an accurate estimate of its incidence or laterality was not possible because of the frequency of cataracts and nystagmus and the difficulty in obtaining adequate fundus examination. toxoplasmosis: Twenty-one patients with congenital toxoplasmosis have been examined and followed for varying time periods, 7 for 20 years or more. The major reason for initial examination was parental awareness of an ocular deviation. Twelve children (57%) presented between the ages of 3 months and 4 years with an initial diagnosis of strabismus, 9 of whom had minor complaints or were diagnosed as part of routine examinations. All cases in this study have had evidence of retinochoroiditis, the primary ocular pathology of congenital toxoplasmosis. Two patients had chronic and recurrent inflammation with progressive vitreal traction bands, retinal detachments, and bilateral blindness. Macular lesions were always associated with central vision loss; however, over a period of years visual acuity gradually improved in several patients. Individuals with more severe ocular involvement were also afflicted with the most extensive central nervous system deficits, which occurred following exposure during the earliest weeks of gestation. CONCLUSIONS: Although congenital infection due to rubella virus has been almost completely eradicated in the united states, the long-term survivors from the prevaccination period continue to experience major complications from their early ocular and cerebral defects. They may be afflicted by the persistence of virus in their affected organs and the development of late manifestations of their congenital infection. Congenital toxoplasmosis continues to be the source of major defects for 3,000 to 4,100 infants in the united states each year; the spectrum of defects is wide and may vary from blindness and severe mental retardation to minor retinochoroidal lesions of little consequence. Effective solutions for either the prevention or treatment of congenital toxoplasmosis have not been developed in this country but are under intensive and continuing investigation.- - - - - - - - - - ranking = 1keywords = ophthalmia (Clic here for more details about this article) |
2/60. pseudomonas orbital cellulitis.A 3-month-old infant being treated for bronchitis developed a rapid onset but otherwise typical orbital cellulitis. Because gram-negative infections and septicemia are common occurrences in the newborn nursery, this patient was given systemic gentamicin and ampicillin. Sinus x-rays were not attempted. Two days after treatment the eyelids were opened. A strikingly large corneal ulcer with perforated globe and endophthalmitis was found. pseudomonas aeroginosa was cultured from the blood, conjunctiva, and throat. A diagnosis of pseudomonas orbital cellulitis with secondary corneal perforation and endophthalmitis was made. The source of infection was believed to be the respiratory tract.- - - - - - - - - - ranking = 24.512812005672keywords = endophthalmitis (Clic here for more details about this article) |
3/60. Bacterial endophthalmitis following suture removal after penetrating keratoplasty.Of three cases of bacterial endophthalmitis occurring after removal of corneal sutures following penetrating keratoplasty, two were associated with wound dehiscence and one was not. Factors that may predispose to wound dehiscence and subsequent infection are: use of fine suture material, corticosteroids, and chronic topical antibiotics; early removal of corneal sutures; lack of adherence to strict asepsis prior to and after suture removal; and open suture tracts that may be kept open by incarceration of vitreous strands. Late corneal wound dehiscence may occur with subsequent development of endophthalmitis as long as three days after suture removal. The use of topical antibiotics before and after suture removal may decrease the potential for infection. In addition, early recognition of intraocular infection by the patient and the surgeon for immediate institution of antimicrobial and anti-inflammatory therapy may preserve useful vision.- - - - - - - - - - ranking = 73.538436017015keywords = endophthalmitis (Clic here for more details about this article) |
4/60. Tubercular endophthalmitis simulating retinoblastoma.PURPOSE: To report a case of tubercular endophthalmitis simulating retinoblastoma. methods: Case report. An 8-year-old female presented with a history of complete loss of vision and a white pupillary reflex in the left eye of 3 month's duration. RESULTS: retinoblastoma could not be excluded on the basis of clinical examination and relevant investigational studies. In the left eye, a computed tomography (CT) scan demonstrated a large vitreous mass with foci of calcification. Enucleation in the left eye was performed, and histopathological examination revealed a chronic granulomatous endophthalmitis and acid-fast bacilli consistent with tubercular pathology. CONCLUSION: This case illustrates that tubercular endophthalmitis with leukocoria and a vitreous mass containing focal calcification may simulate retinoblastoma.- - - - - - - - - - ranking = 85.79484201985keywords = endophthalmitis (Clic here for more details about this article) |
5/60. rifabutin-associated hypopyon uveitis in human immunodeficiency virus-negative immunocompetent individuals.OBJECTIVE: To report the occurrence of rifabutin-associated hypopyon uveitis in human immunodeficiency virus (hiv)-negative immunocompetent individuals. DESIGN: Retrospective case series. PARTICIPANTS: Three hiv-negative subjects on rifabutin and clarithromycin for mycobacterium avium complex infections with hypopyon uveitis are described. One subject was iatrogenically immunosuppressed because of a prior lung transplant. Two subjects had no known immunosuppressive conditions. INTERVENTION: Topical and regional steroid therapy. Discontinuation of rifabutin was required in two subjects. MAIN OUTCOME MEASURES: visual acuity, resolution of hypopyon, anterior uveitis, and vitreitis. RESULTS: All subjects had resolution of hypopyon after therapy, two within 24 hours of beginning topical steroids. Vitreitis resolved with the discontinuation of rifabutin in two subjects. Chronic low-grade anterior uveitis and vitreitis were observed in the remaining subject, whose rifabutin dose was lowered but not discontinued because of active mycobacterium avium complex osteomyelitis. CONCLUSIONS: rifabutin-associated uveitis is well described in hiv-positive individuals, but it has been reported only once in an hiv-negative individual. We report two cases of hypopyon uveitis in immunocompetent individuals and one case in an immunosuppressed hiv-negative individual. All three subjects were receiving concurrent rifabutin and clarithromycin. awareness that this entity can occur in hiv negative and nonimmunosuppressed individuals and that it can mimic infectious endophthalmitis may spare the subject from an invasive workup of systemic infection.- - - - - - - - - - ranking = 12.256406002836keywords = endophthalmitis (Clic here for more details about this article) |
6/60. Clinical and electrophysiological findings in autosomal dominant vitreoretinochoroidopathy: report of a new pedigree.PURPOSE: To report the clinical and electrophysiological findings in a three-generation pedigree with autosomal dominant vitreoretinochoroidopathy. methods: Sixteen members of a three-generation pedigree with autosomal dominant vitreoretinochoroidopathy were examined clinically, including measurement of the corneal diameter. In 14 persons, Goldmann perimetry, axial length determination and electro-oculography were carried out. electroretinography, according to ISCEV standards, was performed in 11 of 12 affected persons. RESULTS: Characteristic annular peripheral pigmentary changes were present in all affected members, as well as chorioretinal atrophy varying from a tigroid aspect to marked atrophy. Four patients presented a microcornea and shallow anterior chamber without microphthalmia. The visual fields appeared to narrow with ageing. The electro-oculography was pathological in the affected patients and normal in the unaffected. The electroretinographic amplitude responses tended to worsen with age, with maintenance of near normal latencies. CONCLUSION: The clinical presentation of autosomal dominant vitreoretinopathy is variable. electrooculography seems to be a discriminative test. The condition may be associated with anterior segment abnormalities other than presenile cataract, such as microcornea, shallow anterior chamber and angle closure glaucoma.- - - - - - - - - - ranking = 1keywords = ophthalmia (Clic here for more details about this article) |
7/60. Foreign body reaction with delayed extrusion of ganciclovir implant in a patient with immune recovery vitritis syndrome.PURPOSE: To report a case of delayed extrusion of primary ganciclovir implants in a patient with immune recovery vitritis syndrome. METHOD: Interventional case report. A 54-year-old hiv positive male patient with immune recovery vitritis syndrome had spontaneous extrusion of bilateral ganciclovir devices 4 years after primary implantation. RESULT: The extruded ganciclovir implants were removed from both eyes, and removal was complicated by vitreous hemorrhage in one eye. Histopathological examination of the extruded implant, LE, showed marked inflammation and evidence of foreign body reaction. CONCLUSION: Excess inflammation in eyes with immune recovery vitritis syndrome may trigger a foreign body reaction that results in a delayed extrusion of primary ganciclovir implants. The site of ganciclovir implants in patients with immune recovery vitritis syndrome should be regularly inspected for eroding struts to prevent secondary endophthalmitis.- - - - - - - - - - ranking = 12.256406002836keywords = endophthalmitis (Clic here for more details about this article) |
8/60. Histopathological correlates of presumed ocular histoplasmosis.There are very few eyes with the ocular histoplasmosis syndrome that have been studied as such by the ophthalmic pathologist. Hoefnagels and Pijpers [6] were the first to demonstrate H. capsulatum in the human eye. However, this was a case of endophthalmitis and not the clinically observe syndrome. Klintworth et. al. [7] demonstrated the organism histologically in granulomatous choroiditis occurring in dissemiated histoplasmosis. The hot was compromised immunologically, and this again is somewhat different from the typical clinical situation. The histopathological material available for study was derived from the eyes of patients enucleated after the diagnosis of malanoma at the AFIP, nd from autopsy material from the Wilmer Institute. These five cases have a number of findings in common. The atrophic scars and punched-out sponts in the periphery and elsewhere correlate with an absence of the pigment epithelium. The degree of inflammation, usually lymphocyte infiltration, can be variable...- - - - - - - - - - ranking = 12.256406002836keywords = endophthalmitis (Clic here for more details about this article) |
9/60. Corneal degeneration after silicone oil tamponade in a photorefractive keratectomy treated eye.Three years after uneventful excimer laser photorefractive keratectomy in both eyes, a 34-year-old man sustained a perforating injury in the left eye. The severe injury, followed by endophthalmitis and retinal detachment, necessitated vitrectomy, lensectomy, and an internal tamponade with silicone oil. One month after the accident and operations, disk-shaped corneal edema corresponding to the laser treatment zone appeared. The edematous region showed a circular, ring-like epithelial thickening at the borders and central corneal epithelial erosion. The anterior stroma developed a central opacity that was separated by a clear rim from the developing silicone-oil keratopathy with the typical band shape.- - - - - - - - - - ranking = 12.256406002836keywords = endophthalmitis (Clic here for more details about this article) |
10/60. Internal ophthalmomyiasis presenting as endophthalmitis associated with an intraocular foreign body.Ophthalmomyiasis interna infestation by fly larva can present in various forms. A 3-year-old girl with a 15-day history of pain, redness, and tearing of the right eye was referred to our clinic with the diagnosis of endophthalmitis associated with an intraocular foreign body, based on clinical and ultrasonographic findings. The patient underwent pars plana vitrectomy, during which an 8-mm long larva was encountered within the vitreous cavity. It was removed and identified as a cattle botfly. The patient developed a retinal detachment 1 month postoperatively, but the family refused further treatment and the patient was lost to follow-up. Ophthalmomyiasis should be included in the differential diagnosis of endophthalmitis and intraocular foreign bodies in patients from rural areas.- - - - - - - - - - ranking = 73.538436017015keywords = endophthalmitis (Clic here for more details about this article) |
