The purpose of this study was to compare the IOP fluctuations in the daytime tension curves of glaucoma patients under ocular hypotensive therapy with those of patients previously submitted to trabeculectomy. We also evaluated the IOP peaks and fluctuations for the same patients in response to the water-drinking test (WDT). The study included 30 primary open-angle glaucoma (POAG) patients using ocular hypotensive medications and with no history of previous intraocular surgery (medical group), and 30 POAG patients previously submitted to one or more trabeculectomies though taking no medication at the time of the study (surgical group). All patients were submitted to a diurnal tension curve--DTC (8:30-17:00/3-hour intervals) followed by the WDT. The IOP peak and IOP fluctuation during the diurnal tension curve were significantly greater in the medical group than in the surgical group. The same was observed following the WDT. From an overall baseline IOP of 10.6 mmHg, the mean IOP change following the WDT was 13% in the surgical group and 40% in the medical group. Patients submitted to trabeculectomy have less TOP fluctuations during the diurnal tension curve and following a water-drinking provocative test. This effect could represent an additional benefit of surgery in controlling the intraocular pressure of glaucomatous patients.

Aims To compare retinal nerve fibre layer (RNFL) measurements were carried out with two different versions of an optical coherence tomography device in patients with band atrophy (BA) of the optic nerve and in normal controls. Methods The RNFL of 36 eyes (18 with BA and 18 normals) was measured using an earlier version of an optical coherence tomography device (OCT-1). The measurements were repeated using a later version of the same equipment (OCT-3), and the two sets of measurements were compared. Results Using OCT-1, the peripapillary RNFL thickness (mean7SD, in lm) in eyes with BA measured 80.4276.94, 99.81714.00, 61.69713.02, 101.70712.54, and 57.36716.52 corresponding to the total RNFL average, superior, temporal, inferior, and nasal quadrants, respectively. Using OCT-3, the corresponding measurements were 63.1176.76, 81.22713.34, 39.5078.27, 86.72715.16, and 45.0578.03. Each of these measurements was significantly smaller with OCT-3 than with OCT-1. In normal eyes, RNFL average and temporal quadrant OCT-3 values were significantly smaller than OCT-1 values, but there was no significant difference in measurements from the superior, inferior, and nasal quadrant.Conclusions RNFL measurements were smaller with OCT-3 than with OCT-1 for almost all parameters in eyes with BA and in the global average and temporal quadrant measurements in normal eyes. Investigators should be aware of this fact when comparing old RNFL measurement with values obtained with later versions of the equipment.

O presente estudo buscou compreender, por meio de abordagem qualitativa, como mães de adolescentes com transtornos alimentares vivenciaram o processo de cuidar de suas filhas desde a gestação até os dois anos de idade, procurando investigar se essas vivências relacionadas à maternidade guardam relação com o aparecimento futuro do transtorno. Foram entrevistadas seis mães de pacientes com anorexia nervosa, que estavam em seguimento ambulatorial em um serviço especializado. Os relatos maternos foram examinados pela análise de conteúdo. Os resultados evidenciaram dificuldades de sustentação (holding) por parte das mães, que acarretaram intenso sofrimento e sentimento de impotência diante das necessidades básicas das filhas. As crianças foram descritas como vorazes e insatisfeitas, sugerindo que teriam vivenciado dificuldades em assimilar o cuidado oferecido por suas mães em seus primeiros anos de vida. Desse modo, os resultados corroboram a importância de investigar as experiências infantis precoces para a compreensão da etiologia dos transtornos alimentares.

Aim To compare the ability of scanning laser polarimeter (SLP) with variable corneal compensation (GDx VCC) and optical coherence tomograph (Stratus OCT) to discriminate between eyes with band atrophy (BA) of the optic nerve and healthy eyes. Methods The study included 37 eyes with BA and temporal visual field (VF) defects from chiasmal compression, and 29 normal eyes. Subjects underwent standard automated perimetry (SAP) and retinal nerve fibre layer (RNFL) scans using GDx VCC and Stratus OCT. The severity of the VF defects was evaluated by the temporal mean defect (TMD), calculated as the average of 22 values of the temporal total deviation plot on SAP. Receiver operating characteristic (ROC) curves were calculated. Pearson's correlation coefficients were used to evaluate the relationship between RNFL thickness parameters and the TMD. Results No significant difference was found between the ROC curves areas (AUCs) for the GDx VCC and Stratus OCT with regard to average RNFL thickness (0.98 and 0.99, respectively) and the superior (0.94; 0.95), inferior (0.96; 0.97), and nasal (0.92; 0.96) quadrants. However, the AUC in the temporal quadrant (0.77) was significantly smaller (Po0.001) with GDx VCC than with Stratus OCT (0.98). Lower TMD values were associated with smaller RNFL thickness in most parameters from both equipments.Conclusion Adding VCC resulted in improved performance in SLP when evaluating eyes with BA, and both technologies are sensitive in detecting average, superior, inferior, and nasal quadrant RNFL loss. However, GDx VCC still poorly discriminates RNFL loss in the temporal quadrant when compared with Stratus OCT.
