Neurological examination is still one of the most important semiological aspects in the daily assessment of the critically ill patient, especially in those with acute neurological injury. Within the neurological examination, the pupillary examination, including size, symmetry, and reactivity to light sti...
RESUMO Objetivo: Calcular as velocidades médias da dilatação de pupila para classificar a gravidade da lesão derivada da escala de coma de Glasgow, estratificada por variáveis de confusão. Métodos: Neste estudo, analisaram-se 68.813 exames das pupilas para determinar a velocidade normal de dilat...
ABSTRACT Purpose: To evaluate the influence of pupil dynamics on the defocus profile and area-of-focus of eyes implanted with a diffractive multifocal intraocular lens (IOL). Methods: This prospective randomized trial was conducted at the Department of Ophthalmology, School of Medicine of Ribeirão Pre...
The objective of this study was to determine changes on intraocular pressure (IOP) and pupil diameter (PD) in healthy cats anesthetized with isoflurane, and premedicated with acepromazine alone or in combination with tramadol. Thirty cats were allocated in two groups (n=15/each) and were treated with ace...
ABSTRACT In this report, we describe a new pupil expander device that was used to obtain adequate pupil dilation and centering in a patient with an iris coloboma. Specifically, we describe the case of a patient with an iris coloboma; a Malyugin ring was inserted to facilitate dilation during phacoemulsif...
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 I...

ABSTRACT The point of centration for refractive surgery is a theme of great importance that generates considerable discussion among specialists and surgeons in the field. Notably, any changes in light can alter the size of the pupil, and the visual axis of the fixation line to the fovea is unique in each...
