ABSTRACT

Hereditary spastic paraplegia (HSP) is characterized by weakness and spasticity of the lower extremities. Kjellin’s syndrome is a rare syndrome associated with HSP. The syndrome is characterized by the presence of bilateral retinal flecks, similar to the findings in Stargardt disease and fundus flavimaculatus. We report the case of a 34-year-old male who presented with complete features of Kjellin’s syndrome, with typical retinal findings observed on multimodal imaging (spectral domain optical coherence tomography [SD-OCT], near-infrared reflectance and autofluorescence imaging). The ophthalmological changes at early stages of the disease may not impair visual acuity. Therefore, the detection of central retinal degeneration requires thorough fundus examination.


A paralisia espástica hereditária (HSP) é caracterizada por fraqueza e espasticidade das extremidades inferiores. A síndrome de Kjellin é uma rara associação de HSP com a presença de flecks retinianos similares aos encontrados em pacientes com doença de Stargardt ou fundus flavimaculatus. Descrevemos os achados em imagens multimodais da retina (tomografia de coerência óptica de domínio espectral [SD-OCT], reflectância próxima ao infravermelho e autofluorescência) em um paciente de 34 anos que apresenta conjunto completo de sinais e sintomas da síndrome de Kjellin. As alterações retinianas em estágios iniciais da doença podem aparecer, mesmo sem redução da acuidade visual, e por isso, para detecção da degeneração central da retina, é necessário exame minucioso do fundo de olho.

ABSTRACT

OBJETIVO: Avaliar prospectivamente com o uso da tomografia de coerência óptica se o uso tópico de latanoprosta induz alterações retinianas em pacientes submetidos à cirurgia de catarata. MÉTODOS: Estudo clínico randomizado, com observador mascarado e um mês de duração. Pacientes pseudofácicos foram tratados com latanoprosta (n=10) ou lubrificante ocular uma vez ao dia (grupo controle - placebo) (n=10). Metade dos pacientes de cada grupo possuía capsulotomia posterior (Nd:YAG laser). Avaliamos o status da barreira hemato-retiniana pela medida da espessura retiniana na fóvea com a tomografia de coerência óptica. Exames de tomografia de coerência óptica e medida da acuidade visual foram realizados antes do início do estudo e com 15 e 30 dias de tratamento. RESULTADOS: Não foi observada alteração significante na média da espessura foveal do grupo controle (p>0,0610). Houve aumento significante na média da espessura foveal nos pacientes tratados com latanoprosta (p<0,0004). Não foi observada alteração na acuidade visual em nenhum paciente. A média da espessura retiniana na fóvea foi significativamente maior no grupo da latanoprosta (p<0,0007). A espessura foveal nos olhos tratados com latanoprosta com cápsula posterior rota foi significativamente maior que a dos pacientes com cápsula íntegra (p<0,0461). Comparando apenas os pacientes com cápsula posterior íntegra, houve diferença significante da espessura foveal entre os pacientes tratados com latanoprosta (236,4 ± 29,4 mm) e placebo (197,8 ± 19,3 mm) apenas na avaliação realizada com 30 dias de tratamento. CONCLUSÕES: Latanoprosta pode levar à quebra da barreira hemato-retiniana em pacientes pseudofácicos. Isso é mais provável de ocorrer em pacientes com cápsula posterior rota.


PURPOSE: To study prospectively using optical coherence tomography whether topical latanoprost induces retinal disorders in patients that underwent cataract surgery. METHODS: Randomized, masked-observer, one-month clinical trial. Pseudophakic patients were treated with latanoprost (n=10) or lubricant drop q.d. (control group) (n=10). Half of the patients of each group presented ruptured posterior capsule (Nd:YAG laser). We evaluated the blood-retinal barrier status assessed by optical coherence tomography measurement of retinal thickness in the fovea. Before the beginning of the study and after 15 and 30 days of treatment, optical coherence tomography images were taken, and the visual acuity examination was performed. RESULTS: There was no statistically significant increase in mean foveal thickness when patients instilled placebo (P>0.0610). A statistically significant increase in retinal thickness in the fovea was observed when patients instilled latanoprost (P<0.0004). No changes were observed in visual acuity in both groups. Mean retinal thickness in the fovea was significantly higher in the latanoprost group (P<0.0007). The mean foveal thickness in latanoprost treated eyes with ruptured posterior capsule was statistically greater when compared with that of intact posterior capsule (P<0.0461). When comparing only the patients with that of intact posterior capsule, there was a statistically significant difference in foveal thickness between patients treated with latanoprost (236.4 ± 29.4 mm) and placebo (197.8 ± 19.3 mm) only at 30 days of treatment. CONCLUSIONS: Latanoprost may lead to disruption of the blood-retinal barrier in pseudophakic patients, and is more probable to occur in patients with ruptured posterior capsule.

ABSTRACT

Relatar a frequência, as causas, as condições da ocorrência e as complicações dos traumas oculares em crianças admitidas ao Hospital de Clínicas da Faculdade de Medicina da Universidade Federal de Uberlândia (HC-UFU). Método: Análise retrospectiva dos prontuários de 38 crianças (com até 15 anos de idade) que sofreram trauma ocular e foram atendidas no setor de emergência do HC-UFU no período de janeiro de 1996 a dezembro 2000. Os dados foram analisados usando o teste t-Student e o teste Qui-quadrado. Resultados: Os meninos foram acometidos aproximadamente 2.5 vezes mais que as meninas. A idade média foi de 8,70 ± 4,56 anos entre meninos e 7,00 ± 3,74 anos nas meninas. A média de segmento foi de 22,63 ± 20,99 meses. Foram encontrados 34 ferimentos penetrantes (89,5%), um ferimento perfurante (2,6%), um ruptura (2,6%) e dois casos com corpo estranho intraocular (CEIO) associado (5,3%), com acometimento corneano em 71.1% dos casos. Os acidentes domésticos foram a causa a mais comum de trauma. A melhor acuidade visual final corrigida encontrada foi melhor de 0,5 em 13,1% dos pacientes com acometimento corneano e 5,3% com acometimento escleral. Seis pacientes (15,8%) perderam completamente a visão do olho afetado. Conclusões: Os traumas oculares nas crianças permanecem um grave problema e continuam sendo uma causa importante de perda da visão. O lugar mais comum de ocorrência é em casa.


To report the frequency, causes, occurrence conditions and complications of eye injuries in children admitted in the Clinic Hospital of the Medical College of the Federal University of Uberlândia (HC-UFU). Method: Retrospective review of the records of 38 children (15 years of age or younger) that suffered penetrating injuries and were assisted at the HC-UFU emergency room from January 1996 through December 2000. Results: the male to female ratio was approximately 2.5:1. The mean age was 8.70 ± 4.56 years between boys and 7.00 ± 3.74 years in girls. We found 34 penetrating injuries (89.5%). Domestic accidents were the most common cause of injury. Six patients (15.8%) lost the vision of the injured eye completely. Conclusions: Serious eye injuries in children remain n a problem and the most common place for it occurs is the home and ocular trauma continues being an important cause of vision impairment.

ABSTRACT

Bilateral endogenous endophthalmitis is a rare condition initiated by infection by microbes in the bloodstream, such as those arising from a foci of infective endocarditis. We report a case and discuss the diagnostic aspects and the clinical outcome of a patient with characteristic findings of the disease. The patient was a 49 year old white male who had a metallic aortic valve implanted 7 months previously, and who presented to the hospital with 10 days of fever, cough and dyspnea, then diarrhea and mental confusion. On the second day of hospitalization, he experienced sudden loss of vision in both eyes. A Gram-positive coccobacillus was isolated from the bloodstream, he was treated with fluoroquinolone with disappearance of fever, decreased ocular inflammation, and improvement in his vision to light perception. He later underwent valve replacement surgery but died during the procedure. We review the occurrence of ocular signs and symptoms and their importance in patients with endocarditis.
