    Angiografia: segurança x economia
    (Conselho Brasileiro de Oftalmologia, 2006-12-01) Torres, Rogil José De Almeida [UNIFESP]; Muccioli, Cristina [UNIFESP]; Casella, Antonio Marcelo Barbante; Regonha, Eduardo [UNIFESP]; Luchini, Andréa; Weiss, Wilma; Frecceiro, Paulo Roberto; Instituto Penido Burnier; Universidade Federal de São Paulo (UNIFESP); Universidade Estadual de Londrina; Centro Oftalmológico de Curitiba
    PURPOSE: To evaluate the safety, effectiveness, and cost of angiofluoresceinographic examination by using both the least amount of dye as well as digital equipment along with a laser photocopier. METHODS: Prospective and comparative study carried out in a group of 70 patients, who underwent an angiographic evaluation with a conventional retinographer injecting 5 ml sodium fluorescein at 10% (control group) as well as a group of 70 patients who underwent an angiographic evaluation with a digital retinographer injecting 2 ml fluorescein at 10% (study group). Arterial pressure, heart rate and oximetry were assessed prior to and after the dye injection. Organic reactions related to the examination were reported. Photograph quality as well as cost between the two techniques were compared. RESULTS: Control group patients showed a greater increase in systolic and diastolic arterial pressure. Heart rate, oximetry measurement and adverse reactions did not show any significant statistical differences between both groups. As for the quality of photographs, a better performance was noticed in the control group. As for the cost, the examination carried out in the study group required lower cost and thus saved around 54.8% per examination in relation to the control group. CONCLUSION: The examination carried out with a lower dose of fluorescein using digital equipment along with a laser photocopier provided greater stability in the systolic and diastolic arterial pressure. However, it did not have any influence on heart rate, oximetry or adverse reactions such as nausea, vomiting, syncope and rashes. The quality of photographs was poor although they enabled diagnosis as well as therapy follow-up for those who carried out the examination. Moreover, economically the above procedure represented a gain of 66.26%, against 25.81% in relation to the conventional equipment.

    Hemorragia peripapilar em pacientes com glaucoma e sua relação com o tronco vascular retiniano
    (Conselho Brasileiro de Oftalmologia, 2008-08-01) Teixeira, Sérgio Henrique [UNIFESP]; Mello, Paulo Augusto de Arruda [UNIFESP]; Paranhos Junior, Augusto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Instituto Israelita de Ensino e Pesquisa Albert Einstein
    PURPOSE: To investigate the correlation between optic disc hemorrhages (ODHs) and the position of the central retinal vessel trunk (RVT) in patients with glaucoma. METHODS: Fundus photographs of 1,830 participants were reviewed. The exit position of the central retinal vessel trunk was classified as being in the superior or inferior hemisphere of the optic disc and the relative vertical position was expressed as a fraction of the disc diameter (ratio between the position of the trunk and the diameter of the disk). A group of patients from the same population, but without ODHs, was randomly selected and compared with the patients with ODHs. RESULTS: Among the 1,830 patients, 53 hemorrhages were detected in 41 patients with glaucoma or suspected glaucoma. We found an inverse relationship between the inferior/superior position of the central RVT and the inferior/superior position of the hemorrhages (Kappa= -0.34). Using the trunk/disc ratio, we found that superior ODHs correlated with inferior RVTs (trunk/disc ratio, 0.450; SD=0.070) and inferior ODHs correlated with superior RVTs (trunk/disc ratio, 0.510; SD=0.054) (p=0.027). The number of patients with normal tension glaucoma was significantly higher among patients with ODHs than among those without ODHs (p=0.009). CONCLUSION: Our patients had a negative correlation between the position of central RVT and the location of the ODHs. Normal tension glaucoma was more prevalent among patients with ODHs than among those without it.

    Lipemia retinalis in a 35-day-old infant with hyperlipoproteinemia: case report
    (Consel Brasil Oftalmologia, 2008-03-01) Cypel, Marcela [UNIFESP]; Manzano, Roberta [UNIFESP]; Reis, Frederico Augusto dos [UNIFESP]; Ishida, Noemi; Ayhara, Teruo; Universidade Federal de São Paulo (UNIFESP); Santa Casa Misericordia São Paulo
    A rare case of hyperlipropoteinemia in a 35-day-old infant who presented not only high blood levels of cholesterol and triglycerides but also an ocular manifestation described as lipemia retinalis. the fundoscopic abnormality cleared as the levels of chilomicrons in plasma dropped. Lipemia retinalis is an important and reliable parameter of high levels of chilomicrons and triglycerides and should be considered as a significant clue while diagnosing.
