Manejo da coroidite interna punctata complicada por membrana neovascular sub-retiniana / Management of punctate inner choroidopathy complicated by subretinal neovascular membrane

RESUMO Este trabalho visou evidenciar a importância da detecção precoce da coroidite interna punctata e destacar sua fisiopatologia inflamatória e possíveis diagnósticos diferenciais dentro das white dot syndromes. O destaque foi dado principalmente à coroidite multifocal e à panuveíte, ao se demonstrar sua epidemiologia peculiar em mulheres jovens, caracterizar sua apresentação clínica típica na fundoscopia e explorar as vantagens e as desvantagens de realizar os exames complementares que fazem parte da análise multimodal útil para o diagnóstico (especialmente a angiografia fluoresceínica, a tomografia de coerência óptica e a indocianina verde). Descreve-se o caso de uma mulher de 28 anos diagnosticada com coroidite interna punctata com membrana neovascular coroidal em olho direito. O tratamento foi realizado com injeção intravítrea de aflibercepte e corticoterapia sistêmica 1mg/kg ao dia. Este relato é importante por permitir debater o manejo da coroidite interna punctata durante a gestação e a decisão de realizar o tratamento mediante uma diversidade de opções terapêuticas.

ABSTRACT This work aimed to demonstrate the importance of early detection of punctate inner choroidopathy, highlighting the pathophysiology of inflammation and the differential diagnoses among white dot syndromes. Special attention was given to multifocal choroiditis and panuveitis, by demonstrating the peculiar epidemiology in young women, characterizing the typical clinical presentation in ophthalmoscopy, and exploring the advantages and disadvantages of performing the complementary examinations, which are part of the multimodal analysis useful for diagnosis (particularly fluorescein angiography, optical coherence tomography, and indocyanine green). We report the case of a 28-year-old female, diagnosed as punctate inner choroidopathy with choroidal [N.T. no título aparece subretinal = subrretiniana] neovascular membrane in the right eye. She was treated with intravitreal injection of aflibercept and systemic corticosteroid 1 mg/kg/day. This case report is important for addressing the management of punctate inner choroidopathy during pregnancy, and the decision to carry out treatment considering diverse therapeutic options.

Esporotricose ocular: manifestações atípicas / Ocular sporotrichosis: atypical manifestations

Resumo A esporotricose humana e animal é uma infecção subaguda a crônica causada pelo fungo dimórfico Sporothrix schenckii. A esporotricose ocular tem ganhado destaque em função da epidemia de esporotricose urbana enfrentada pelo estado do Rio de Janeiro na última década e se apresenta classicamente como conjuntivite granulomatosa, mas formas atípicas podem ocorrer. Este artigo tem por objetivo relatar 2 casos atípicos de esporotricose ocular em pacientes imunocompetentes, ambos apresentando quadro clínico compatível com a síndrome oculoglandular de Parinaud associada à dacriocistite em um caso e presumivelmente à coroidite no outro caso.

Abstract Human and animal sporotrichosis is an infection caused by the dimorphic fungus Sporothrix schenckii, which is classified from subacute to chronic. Ocular sporotrichosis has been highlighted due to the epidemic of urban sporotrichosis faced by the state of Rio de Janeiro in the last decade and presents classically as granulomatous conjunctivitis, but atypical forms may occur. This article aims to report two atypical cases of ocular sporotrichosis in immunocompetent patients, both presenting a clinical picture compatible with Parinaud oculoglandular syndrome associated with dacryocystitis in one case and presumably to choroiditis in the other case.

Central serous chorioretinopathy mistaken for tuberculous choroiditis

To report a patient erroneously diagnosed with tuberculous choroiditis who was accordingly treated with long term steroids which in turn, worsened the actual disease process that turned out to be central serous chorioretinopathy [CSC]. A 59-year-old Caucasian man developed a chorioretinal disease in his right eye in 1997. Having a positive tuberculin skin test, tuberculous chorioretinitis was suspected and antituberculous therapy was administered for 4 months. In 2005, visual symptoms in the same eye recurred and despite negative interferon gamma release assay, tuberculous choroiditis was considered as the diagnosis and the patient further received massive corticosteroid therapy along with antituberculous agents. Despite a deteriorating clinical picture, therapy was continued. Upon initial examination at our center, no sign of inflammation was observed and a diagnosis of CSC was made, consequently steroid therapy was terminated. In some chorioretinopathies, it is difficult to differentiate inflammatory from non-inflammatory causes. One should observe the course of the disease and question the initial diagnosis when no improvement or deterioration occurs despite therapy

Current approach in the diagnosis and management of posterior uveitis.

Posterior uveitic entities are varied entities that are infective or non-infective in etiology. They can affect the adjacent structures such as the retina, vitreous, optic nerve head and retinal blood vessels. Thorough clinical evaluation gives a clue to the diagnosis while ancillary investigations and laboratory tests assist in confirming the diagnosis. Newer evolving techniques in the investigations and management have increased the diagnostic yield. In case of diagnostic dilemma, intraocular fluid evaluation for polymerase chain testing for the genome and antibody testing against the causative agent provide greater diagnostic ability.

Ocular Sarcoidosis in a Korean Population

The aim of current study was to evaluate the incidence and characteristics of ocular sarcoidosis in a Korean population. We conducted a retrospective study of 104 consecutive patients with biopsy-proven sarcoidosis seen at Asan Medical Center in Seoul, Korea, from 1993 to 2007. Medical records, photographs, and fluorescein angiograms were reviewed. Of 104 patients, 22 (21%) had intraocular involvement with female predominance (86%, M:F=3:19). Of the 39 eyes with ocular involvement, 16 (41%) eyes had isolated anterior uveitis, 12 (31%) eyes had intermediate uveitis, 6 eyes (15%) had panuveitis with retinal vasculitis, and 5 (13%) eyes had panuveitis with punched multifocal choroiditis. Mean duration of ophthalmologic follow-up was 62 months. All ocular inflammation was well managed with topical steroid and/or systemic steroid with relatively good final visual outcomes. Ocular complications such as cataract (12 eyes, 30%), glaucoma (6 eyes, 15%), vitreous opacity (1 eye, 3%), cystoid macular edema (3 eyes, 7%), neovascularization (2 eye, 5%), and epiretinal membrane (4 eye, 10%) were related to ocular sarcoidosis. In Korea, where sarcoidosis is very rare, our study indicates relatively low ocular and predominantly non posterior segment involvement with relatively good visual prognosis.

Remote hypofluorescent dots in recurrent ocular toxoplasmosis on indocyanine green angiography

PURPOSE: To report the findings of indocyanine green angiography performed in patients with recurrent ocular toxoplasmosis. METHODS: Institutional prospective analysis of 23 eyes from 23 immunocompetent patients with recurrent ocular toxoplasmosis aged between 17 and 41 years. These patients underwent a complete ocular examination including indocyanine green angiography. RESULTS: Multiple hypofluorescent spots distant from the recurrent active lesion of retinochoroidal toxoplasmosis were found in 26.08 percent of the patients. We also found multiple hypofluorescent satellite dots in 69.56 percent of the patients. CONCLUSION: These remote dots seen suggest either a more widespread choroidal involvement in this disease and this can represent simply remote collections of inflammatory cells or subclinical infection.

OBJETIVOS: Relatar os achados da angiografia com indocianina verde, realizados em pacientes com recidiva de toxoplasmose ocular. MÉTODOS: Análise institucional e prospectiva de 23 olhos de 23 pacientes, imunocompetentes com idades entre 17 e 41 anos. Estes pacientes foram submetidos a exame oftalmológico de rotina e a angiografia com indocianina verde. RESULTADOS: Foram encontrados múltiplos pontos hipofluorescentes distantes da lesão ativa recidivada da toxoplasmose retino-coroidiana em 26,08 por cento dos casos, chamados por nós de pontos remotos e encontramos também, pontos hipofluorescentes circundando ou próximos da lesão ativa recidivada em 69,56 por cento dos casos. CONCLUSÃO: Os pontos hipofluorescentes distantes da lesão ativa recidivada, chamados de pontos remotos, não descritos previamente na doença, demonstram um maior envolvimento da coróide e podem significar coleções remotas de células inflamatórias ou infecção subclínica.

Bilateral acute acquired toxoplasmic retinochoroiditis after steroid therapy for hantavirus pulmonary syndrome: case report

Description of a case of acute acquired ocular toxoplasmosis following hantavirus pulmonary syndrome. A 41-year-old man presenting hantavirus pulmonary syndrome, confirmed in the laboratory by detection of IgM antibodies to the virus, was submitted to high doses of intravenous corticosteroids for two months. After clinical improvement of hantavirus pulmonary syndrome the patient presented visual loss in both eyes that was secondary to a toxoplasmosis retinitis. The retinitis resolved with anti-toxoplasma therapy. Acquired toxoplasmic retinochoroiditis can occur following steroid therapy for hantavirus pulmonary syndrome.

Descrição de um caso de toxoplasmose ocular adquirida pós-síndrome pulmonar por hantavírus. Paciente com 41 anos do sexo masculino apresentando síndrome pulmonar por hantavírus, confirmado no laboratório pela detecção de anticorpos IGM para o vírus, foi submetido a altas doses de corticosteróides intravenosos durante dois meses. Após melhora clínica da síndrome pulmonar por hantavírus, apresentou perda visual em ambos os olhos secundária a retinite por toxoplasmose confirmada com sorologia (IGG e IGM positivo) A retinite resolveu após terapia sistêmica específica. A retinite por toxoplasmose pode ocorrer após terapia sistêmica com esteróide para síndrome pulmonar por hantavírus.

The fundoscopic features for differentiation between polypoidal choroidal vasculopathy and choroidal neovascularization from age-related macular degeneration.

OBJECTIVES: To evaluate the fundus features that can differentiate polypoidal choroidal vasculopathy (PCV) from choroidal neovascularization (CNV) due to age-related macular degeneration (AMD). DESIGN: Retrospective, case-control study. MATERIAL AND METHOD: The fundoscopic features of AMD-related CNV and PCV were compared for evaluation of relative risks for PCV. The odds ratio, sensitivity and specificity of each feature were also calculated. RESULTS: A total of 30 patients, 15 PCV and 15 age-matched non-PCV cases, approved by indocyanine green angiography (ICG), were enrolled. The odds ratio is highest for subretinal polyp-like structure and lowest in scar formation (28 and 0, respectively) and these ratios are statistically significant differences (p = 0.001 and 0.032 respectively). The ratio for either circinate exudates, or larger than 4-disc area of subretinal fluid, or retinal pigment epithelial detachment is 1.75. The ratio for peripapillary location is 1.63. Subretinal membrane has a ratio of 1 while subretinal hemorrhage and subretinal fibrin have less than 1; they are 0.31 and 0.23 respectively. All these ratios are not statistically significant differences (p > 0.05). CONCLUSION: The orange polyp-like structures beneath retina are hallmarks for diagnosis of PCV. The "serosanguineous retinopathy", described as serous retinal deatchment or retinal pigment epithelial detachment with circinate exudates with or without subretinal hemorrhage at the posterior pole or peripapillary region, may also suggest the condition.

Current perspectives of herpesviral retinitis and choroiditis.

Vision-threatening viral retinitis are primarily caused by members of the herpesvirus family. The biology and molecular characterization of herpesviruses, clinical presentations of retinopathies, pathology and pathogenesis including the host responses, epidemiology and the laboratory methods of aetiological diagnosis of these diseases are described. Clinical syndromes are acute retinal necrosis (ARN), progressive outer retinal necrosis (PORN), cytomegalovirus (CMV) retinitis, multifocal choroiditis and serpiginous choroiditis besides other viral retinopathies. Herpes simplex virus (HSV) retinitis is more common in immunocompetent persons while varicella zoster virus (VZV) affects both immunocompetent and immunosuppressed patients equally. CMV retinitis is most common among patients with AIDS. The currently employed laboratory methods of antigen detection, virus isolation and antibody detection by enzyme linked immuno-sorbent assay (ELISA) have low sensitivity. Polymerase chain reaction (PCR) has increased the value of diagnosis due to its high clinical sensitivity and absolute specificity in detection of herpesviruses in intraocular specimens.

Coriopatía serpiginosa: descripción de un caso clínico / Choroidopathia serpiginosa: description of a clinical case

Choroiditis serpiginosa is an infrequent disorder, which is chronic, progressive, bilateral, and recurrent; in primary form it affects the pigmented epithelium of the retina and the choriocapillary layer within the eye. It typically begins juxtapapillary and progresses to extend centrifugally to the optic disc, usually affecting the macula and thus decreasing visual acuity. It's etiology is unknown and it debutes in acute form in adult patients, without preference for sex. It's treatment includes the use of systemic corticosteroids, non steroidal anti-inflammatory drug (NSAID), and immunosuppressant agents. In this paper we document the clinical case of a diabetic, 61 year old man, having the disease in an inactive phase with serious visual sequelae.

Coroiditis serpiginosa es un desorden poco frecuente, crónico, progresivo, bilateral y recurrente que efecta en forma primaria al epitelio pigmentario de la retina y la coriocapilar. Típicamente comienza yuxtapapilar y su progresión se extiende en forma centrífuga al disco óptico, afectando usualmente la mácula, disminuyendo así la agudeza visual. Su etiología es desconocida y debuta en forma aguda en pacientes de edad madura sin predilección por sexo. El tratamiento incluye el uso de corticoesteroides sistémicos, antiinflamatorios no esteroidales (AINES) y agentes inmunosupresores. Presentamos el caso clínico de un hombre diabético de 61 años con enfermedad en fase inactiva con secuelas visuales serias.

Uveite tuberculosa: a propósito de 5 casos / Tuberculosis uveitis: a five-case report

Tuberculose é rara nos paises desenvolvidos (9,3/100000 nos EUA). Entretanto com o surgimento do vírus da imunodeficiência adquirida (HIV) a incidência tem aumentado. O diagnóstico definitivo de retinocoroidite tuberculosa requer demonstraçäo do bacilo nos tecidos e fluidos oculares e, portanto, o diagnóstico é usualmente presuntivo baseado em: 1) lesäo compatível no fundo de olho; 2) eliminaçäo de outras etiologias; 3) coexistência de infecçäo tuberculosa; 4) teste de Montoux positivo; 5) resposta clínica a teste terapêutico. Säo apresentados 5 casos com perda de visäo secundária a uveite tuberculose näo relacionada à AIDS. Os pacientes foram tratados com sucesso por uma associaçäo de pirazinamida 2g qD 2m, rifampicina 600mg qD 6m, e isoniazida 400mg qD 12m. Uma boa resposta, com melhora na acuidade visual ou reduçäo significativa na reaçäo inflamatória, foi obtida já no primeiro mês de tratamento. Enfatiza-se que tuberculose ainda é comum em diversas regiöes: no estado do Rio Grande do Sul a incidência é de 31/100000; na Asia e Africa é de 110 e 165/100000 respectivamente. Uveite tuberculosa deveria ser mais diagnosticada nessas regiöes
