Photothrombosis using low-intensity 810 nm light to direct laser energy continuously at the active leakage sites after intravenous ICG infusion induced rapid VA recovery in patients with persistent CSC; accordingly, restoration of the macular architecture was evidenced on OCT, and no recurrence was noted 12 months after IMP.

To investigate the relevance of lacking or diminished visual input on the expression of migraine, we evaluated its prevalence and clinical features in a population of visually impaired subjects. Between September 1999 and April 2000, 203 visually impaired subjects with a headache inventory were surveyed. Those with headache were assessed according to IHS criteria for the presence of migraine. Migraineurs had their symptoms further detailed through an interview and a headache diary. Of the 104 subjects reporting headaches during the last 6 months, 29 had migraine (14.2%). The prevalence of migraine was not influenced by whether the visual impairment was complete or partial. Mean frequency of migraine attacks was 2.7/month. Most subjects (96%) reported severe and/or moderate attacks. Nausea, vomiting, aggravation by activity and phonophobia were reported by 62%, 37.9%, 86.2% and 96.6% of the subjects, respectively. Visual impairment does not seem to influence prevalence of migraine or its clinical features.

Objetivos: Avaliar a distribuição da espessura corneana central (ECC) e sua relação com a pressão intra-ocular (PIO) em um grupo de pacientes e demonstrar a utilidade da paquimetria para avaliar a PIO em casos selecionados.Métodos: A espessura corneana central foi determinada em 167 pacientes com mais de 40 anos de idade (319 olhos) por meio de paquimetria ultra-sônica. A pressão intra-ocular foi medida com tonômetro de aplanação de Goldmann.Resultados Conclusão: Observou-se uma regressão linear entre PIO e ECC, ou seja, quanto maior a ECC maior será a PIO. Demonstrou-se a utilidade da paquimetria corneana na avaliação da PIO daqueles pacientes em que esta estava falsamente aumentada ou diminuída na tonometria de aplanação, direcionando a terapêutica a pacientes realmente portadores de glaucoma.

The SRK/T formula demonstrated a satisfactory accuracy to calculate the error of refraction in eyes with medium axial length.
