1. Personality changes and return to work after severe traumatic brain injury: a prospective study
Objective: To evaluate predictors of non-return to work (nRTW) among social, demographic, clinical, and psychiatric variables after severe traumatic brain injury (TBI) in a cohort of Brazilian patients. Methods: Prospective study. Forty-three community-dwelling individuals treated at a Level I trauma center at the time of TBI were evaluated 18 months afte

2. Movimentos oculares e respostas pupilares em prova de leitura e de tomada de decisão lexical de crianças com e sem dislexia do desenvolvimento
The cognitive functioning required in reading and lexical decision making involves various linguistic subsystems that usually are affected in subjects with Developmental Dyslexia. The observation and recording of physiological measures, such as eye movements and pupil diameter, allows inferences about the neural structures involved in reading as well as the

3. FACIAL ATTRACTIVENESS AND EMOTIONAL EXPRESSIONS: IS THERE A RELATIONSHIP TO PUPIL DIAMETER? / Atratividade facial e expressões emocionais: existe relação com o diâmetro da pupila?
This research aimed to evaluate the role of the pupil diameter in attractiveness between individuals of opposite sex and to check the relationship between pupil diameter and some emotional expressions considered universal. Analyzed through both quantitative and qualitative methods, the research was divided into two independent studies. The stimuli for both o

4. A contralateral eye study comparing apodized diffrative and full diffrative lenses: wavefront analysis and distance and near uncorrected visual acuity
PURPOSE: To evaluate intraindividual visual acuity, wavefront errors and modulation transfer functions in patients implanted with two diffractive multifocal intraocular lenses. METHODS: This prospective study examined 40 eyes of 20 cataract patients who underwent phacoemulsification and implantation of a spherical multifocal ReSTOR intraocular lens in one ey

5. Simulation of optical and physiological phenomena of the human vision / Simulação de fenômenos óticos e fisiológicos do sistema de visão humana
The increase in performance of the modern computers has driven scientific work in the areas of computer simulation. Many authors use in their research commercial tools that use embedding algorithms, which sources are not provided, and it makes harder and sometimes impossible, the development of novel theories or experiments. This work explores this gap left

6. Pupil size following dark adaptation in patients with retinitis pigmentosa
According to the equivalent light hypothesis, molecular defects in the photoreceptor lead to a continuous activation of the photoreceptor cascade in a manner equivalent to real light. The consequences in diseases such as retinitis pigmentosa (RP) are as disruptive to the cells as real light. Two forms of the equivalent light hypothesis can be distinguished:

7. A photometric study of the effect of pupil dilatation on Nd:YAG laser iridotomy area.
A photometric study of the effect of pupil dilatation on Nd:YAG laser iridotomy area was performed in 21 eyes of 21 patients. The iridotomy area was 0.075 (0.055) mm-2 (mean (SD)) before pupil dilatation and 0.073 (0.070) mm-2 after pupil dilatation (t test NS). Iridotomy area after pupil dilatation correlated with iridotomy area before pupil dilatation (r =

8. Influence of pupil size on measurements made with the Lens Opacity Meter 701.
The Lens Opacity Meter 701 (Interzeag, Switzerland) is a recently developed instrument for assessing cataract. It measures the degree of scatter of a red light beam by the lens. Fifty patients prior to cataract surgery had measurements made before and after dilatation of the pupil. Inconsistent results were found at pupil diameters of less than 4 mm. It is p

9. Quantification of lens opacification with a commercially available lensometer.
A clinical trial was undertaken to determine whether a commercially available lens opacity meter (LM701), which measures backward scattered light from the lens, provides reliable clinical information about the effect of lens opacities on visual acuity. At the 0.001 level of probability we found a significant relationship between the lens opacity meter readin
