1. Comparision effects of solifenacin, darifenacin, propiverine on ocular parameters in eyes: A prospective study
ABSTRACT Objective To evaluate the effects of solifenacin, darifenacin, and propiverine on nasal-, subfoveal-, temporal choroidal thicknesses (NCT, SFCT, TCT), intraocular pressure (IOP) and pupil diameter (PD). Materials and Methods Patients with overactive bladder (OAB) diagnosed according to The International Continence Society were administered with

2. Efficacy of preoperative nonsteroidal anti-inflammatory drug and the re-dilation technique in minimizing miosis after femtosecond laser in cataract surgery
RESUMO Objetivo: Avaliar a eficácia do uso de anti-inflamatório não-esteróide no pré-operatório e aplicação da técnica de re-dilatação quando necessária para minimizar a variação do tamanho pupilar ao comparar o grau de midríase antes do tratamento com laser de femtosegundo no início da facoemulsificação. Métodos: Esse estudo retrospecti

3. The effect of intracameral epinephrine on pupil size during phacoemulsification and its postoperative effect on specular findings and macular thickness
ABSTRACT Objective: To evaluate pupillary size and vital signs following intraoperative intracameral adrenaline during phacoemulsification and postoperative effect of on co specular microscopy findings and macular thickness by OCT. Methods: A prospective interventional study carried out from December 2014 to December 2015 on 90 eyes. They were divided rand

4. 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

5. 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

6. Comparação da eficácia das lentes intraoculares restor esférica - SN60D3 - e restor asférica - SN6AD3
PURPOSE: To compare distance, intermediate and near visual acuity (VA) ,uncorrected and best corrected, and ocular aberrations in patients who had multifocal aspherical and spherical apodized diffractive intraocular lens (IOL) implantation (Restor, Alcon). METHODS: The best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), distance corrected

7. 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

8. Measuring higher order optical aberrations of the human eye: techniques and applications
In the present paper we discuss the development of "wave-front", an instrument for determining the lower and higher optical aberrations of the human eye. We also discuss the advantages that such instrumentation and techniques might bring to the ophthalmology professional of the 21st century. By shining a small light spot on the retina of subjects and observi

9. 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:

10. Pupil diameter in migraine and tension headache.
Pupil diameter was measured in darkness and in dull and bright illumination in 39 migrainous patients and in 15 tension headache sufferers during headache. In 21 migrainous patients, measurements were repeated during the headache-free interval. Mean pupil diameter was smaller in patients with common migraine at the time of examination than in 20 nonheadache

11. Stimulation of dopamine receptors (type 2) lowers human intraocular pressure.
The interaction between bromocriptine and metoclopramide on intraocular pressure (IOP), pupil diameter, and other parameters were studied in healthy volunteers. Pupil diameter was not affected by both treatments and only bromocriptine lowered IOP. Prior treatment with metoclopramide blocked the IOP-lowering effect of bromocriptine. It is concluded that bromo

12. Altered pupillary size and darkness and light reflexes in Alzheimer's disease.
The purpose was to compare resting pupil diameter in darkness and light, and the pupillary darkness and light reflexes between a group of patients with Alzheimer's disease and a group of healthy old people. Nine medication free patients with Alzheimer's disease and nine healthy control subjects, matched for sex and age with the patients, participated. There
