Manifestaciones oftalmológicas por virus de Epstein-Barr / Ophthalmological manifestations caused by Epstein-Barr virus

Se trata de un paciente masculino de 26 años que acude por disminución brusca de la visión del ojo derecho. Se ingresó como una uveítis posterior dada por exudación extensa en área macular del ojo derecho, acompañada de edema del disco óptico, vasculitis aledaña a la lesión y hemorragias dispersas en llama en el polo posterior. La etiología era controversial y, el tratamiento más apropiado era debatible, por lo que se le realizaron estudios como retinografías seriadas, angiografías fluoresceínicas y reacción en cadena de polimerasa a una muestra del humor acuoso, que confirmó la etiología viral; lo que resultó en una agudeza visual final de 0,1. Posterior a 6 meses del cuadro inicial, el paciente presentó queratitis intraestromal en forma numular -que recurre ante episodios de stress-, para desaparecer luego de terapia tópica con antiinflamatorios no esteroideos y esteroideos. La baja incidencia de casos reportados con uveítis posterior por virus de Epstein Barr resulta de un pobre conocimiento de la presentación de la enfermedad, por tanto un retraso en la instauración del tratamiento. En estos casos la prueba de oro es la reacción de cadena de polimerasa

This article presented a 26 years-old male patient who went to the ocular service with sudden reduction of vision in his right eye. He was admitted to the hospital and diagnosed as posterior uveitis based on extensive exudation in the macular area of the right eye, edema of the optic disk, vasculitis next to the lesion and disperse hemorrhages in the posterior pole. The etiology of this case was controversial and the most suitable treatment was under discussion, so it was decided to perform serial retinographies, fluorescein angiographies and polymerase chain reaction in a aqueous humor sample taken from the patient. The viral etiology was confirmed, resulting in final visual acuity of 0.1. After 6 months of the initial clinical picture, the patient suffered nummular-shaped intrastromal keratitis - it appears in stress episodes- and finally disappears after topical therapy with non-steroidal and steroidal anti-inflammatory drugs. The low incidence of cases reported with posterior uveitis caused by Epstein Barr virus is due to the poor knowledge about the onset of this disease, and leads to delay in applying treatment. The golden rule in this case is the polymerase chain reaction

Ocular Manifestations of Acquired Immunodeficiency Syndrome in Korea

The clinical features of HIV/AIDS-related ocular manifestations in Korean patients were investigated in this study. Data on 200 consecutive Korean patients diagnosed with AIDS who visited the Seoul National University Hospital from January 2003 to June 2008 were reviewed. Fifty-seven patients (28.5%) had ocular manifestations, and they showed significantly lower CD4+ T cell count than patients without ocular manifestations. Among them, 23 (40.3%) patients showed retinal microvasculopathy, and 22 (38.5%) patients showed cytomegalovirus (CMV) retinitis. Other manifestations included retinal vein occlusion (n = 4), herpes zoster ophthalmicus (n = 4), syphilitic uveitis (n = 2), acute retinal necrosis (n = 1), and progressive outer retinal necrosis (n = 1). The mean CD4+ lymphocyte counts of the patients with retinal microvasculopathy and cytomegalovirus retinitis were 108.5 cells/microL and 69.4 cells/microL, respectively. In conclusion, ocular manifestations including CMV retinitis are common complications in Korean patients with AIDS even in the era of highly active anti-retroviral therapy. Compared to previous reports in western countries, prevalence of CMV retinitis is relatively low and CD4+ lymphocytes count at the time of diagnosis is relatively high.

Laboratory results in ocular viral diseases: implications in clinical-laboratory correlation

PURPOSE: To document etiology and predictive value of clinical diagnosis in laboratory confirmed viral diseases. METHODS: Reports of culture-positive cases of samples collected from patients presenting from January 1987 - December 2001 were evaluated. RESULTS: One thousand nine hundred and sixty-four (1964) cultures were submitted during 1987-2001. Twenty-six percent were positive (514). Human herpesvirus 1 was the most frequent agent isolated from all positive culture (56 percent). Adenovirus was the most common virus isolated from conjunctiva (66 percent), human herpesvirus 1 from lid and cornea (76 percent, 88 percent) and cytomegalovirus from vitreous (27 percent). Some unusual pathogens were recovered from conjunctiva as cytomegalovirus and from cornea as adenovirus, enterovirus and cytomegalovirus. Recognition of common viral syndromes was human herpesvirus 1 (88 percent), epidemic keratoconjunctivitis (88 percent), acute hemorrhagic conjunctivitis (70 percent) and varicella zoster virus (100 percent). However, some misdiagnosed cases were observed. Thirteen percent of conjunctivitis thought to be caused by herpes were due to adenovirus, 3.2 percent to Enterovirus, 3.2 percent to varicella zoster virus and 3.2 percent to human cytomegalovirus. Also, 5 percent of cases with a clinical diagnosis of herpes keratitis were caused by adenovirus and 2.7 percent by enterovirus. Finally, 4.8 percent of cases thought to be adenovirus conjunctivitis were herpes conjunctivitis. CONCLUSIONS: Human herpesvirus 1 remains the most frequently isolated virus from ocular sites in general (56 percent). Nonherpetic corneal isolates were in decreasing order: adenovirus, enterovirus and cytomegalovirus. Clinical and laboratory correlation was less than 90 percent. The most misdiagnosed cases were herpes conjunctivitis and keratitis, some cases of adenovirus conjunctivitis some cases of acute hemorrhagic conjunctivitis. It is essential that a rapid and...

OBJETIVOS: Documentar a etiologia e prever a importância do diagnóstico clínico em doenças virais oculares confirmadas em laboratório. MÉTODOS: Todos os relatórios de pacientes com cultura viral positiva durante o período de janeiro 1987 - dezembro 2001 foram analisados. RESULTADOS: Quinhentos e quatorze (514) casos foram encontrados. Em geral, herpesvírus 1 humano foi o agente mais freqüentemente isolado. Adenovírus foi o vírus mais comumente isolado da conjuntiva (66 por cento), herpesvírus 1 humano das pálpebras e córnea (76 por cento, 88 por cento respectivamente) e citomegalovírus do vítreo (27 por cento). Alguns agentes não usuais foram isolados da conjuntiva como citomegalovírus e da córnea como adenovírus, enterovírus e citomegalovírus. Reconhecimento das síndromes virais comuns foi: herpervírus 1 humano (88 por cento), ceratoconjuntivite epidêmica (88 por cento), conjuntivite aguda hemorrágica (70 por cento). Porém, alguns casos com diagnóstico incorreto foram observados. Treze por cento das conjuntivites com diagnóstico de herpes foram causadas por adenovírus, 3,2 por cento por enterovírus, 3,2 por cento por varicella zoster vírus e 3,2 por cento por citomegalovírus. Também, 5 por cento dos casos com diagnóstico clínico de ceratite herpética eram adenovírus e 2,7 por cento enterovírus. Além disso, 4,8 por cento dos casos em que se pensaram em conjuntivite por adenovírus, eram conjuntivite por herpes. Finalmente, 30 por cento dos casos em que se diagnosticaram conjuntive hemorrágica aguda, o agente etiológico era adenovírus. CONCLUSÃO: Em geral herpesvírus humano 1 continua a ser o vírus mais comum encontrado nas infecções oculares (56 por cento). Agentes não herpéticos isolados da córnea foram em ordem decrescente: adenovírus, enterovírus e citomegalovírus. A correlação entre o diagnóstico clínico e laboratorial foi menor do que 90 por cento. Um diagnóstico rápido e específico é essencial em casos de apresentações virais atípicas...

Incidence of various ocular findings in children with chicken pox

Twenty five out of 67 children with chickenpox from the pediatric section had ocular complications. The most common ocular findings were eyelid affections in the form of rashes, vesicles or marginal erosions, acute conjunctivitis and lesions resembling phlyctenules on the bulbar conjunctiva and on the lid margins. Corneal changes in the form of punctate epithelial keratitis, subepithelial marginal infiltrates, peripheral corneal scarring, corneal vascularization and disciform stromal keratitis, were infrequent. Iridocyclitis was a rare ocular finding

Prevalence and clinical features of recurrent herpetic keratitis in upper Egypt

The prevalence and clinical features of recurrent herpes simplex keratitis [RHSK] in Upper Egypt were studied. Of 8447 patients presenting with different eye diseases to Assiut University Hospital, 456 [3.4%] of patients had active recurrent herpetic lesions. The highest incidence of herpetic affection was found in the age group of 30-39 years of both males, 70[26.5%] and females, 46[24.0%] patients. The majority of cases were unilateral, 427[93.6%] patients and presented in the season of winter, 195 [42.8%] patients. RHSK was detected during the first recurrence in 274[60.1%] of patients, and 182.[*39.9%][of cases had more than one recurrence [average3 recurrences in 3 years]. The commonest symptom was pain in 233[51.1]%] - patients and the commonest herpetic lesions were ulcerative keratitis in 319[70%] patients with one recurrence and kerato-uveitis in 47[25.8%] patients with more than one recurrence. RHSK should be considered as one of the serious diseases affecting the cornea in Upper Egypt. The factors affecting the course and seriousness of the disease were discussed
