ABSTRACT The term dysfunctional lens syndrome has gained acceptance in the field and encompasses natural changes due to aging of crystalline lens. The evolution of diagnostic devices has been a key factor in better staging, understanding and characterizing of these degenerative changes. Even with these t...
ABSTRACT Purpose: To measure changes in the anterior ciliary muscle during accommodation at the nasal, superior, temporal, and inferior sectors by means of an anterior chamber optical coherence tomographer, and correlate them with vergence changes. Methods: Twenty-four subjects with healthy, phakic eye...
A tiny structure, the pupil, attracts too much attention, since the antiquity. The pupil as part of the “‘window of/to the soul”, the eyes, it can demonstrate a clinical disorder sign, or simply a psychological expression. In this paper, it is studied the situation in which the pupillary reflex to...
ABSTRACT Purpose: To evaluate the clinical and surgical impacts of phenomena that could occur in intermittent exotropia. Methods: The medical records of intermittent exotropia cases from 1991 to 2014 were retrospectively reviewed. All patients underwent a series of measures, including a protocol to ass...

ABSTRACT Purpose: To assess changes in anatomic structures in the anterior eye segment in terms of axial lengths with accommodation via optical coherence tomography. Methods: In this observational study, 25 eyes of 25 healthy adults were examined using the Visante® omni optical coherence tomography ...
Resumo Objetivo: Comparar as alterações da refração e da biometria ocular na população infantil hipermetrópica com e sem correção óptica total. Métodos: Realizou-se estudo prospectivo longitudinal não randomizado em 41 pacientes com hipermetropia, entre 3 e 6 dioptrias ou/e com esotropia ac...

ABSTRACT Purpose: To assess the accommodation response after short reading periods using a tablet and a smartphone as well as determine potential differences in the accommodation response at various stimulus vergences using a Hartmann- Shack aberrometer. Methods: Eighteen healthy subjects with astigmat...
The authors conducted a review of classical and conflicting theories of accommodation and presbyopia. They make a critical comparison with the findings of magnetic resonance imaging (MRI) that have been developed in recent decades. Based on these studies, formulates a new approach on the subject, shiftin...
This investigation searched for the relationship between amount of nearwork, asthenopic symptoms and visual function, in a group of office workers engaged in telemarketing. Phoria, monocular accommodative facility with +/- 2 lens flippers and near point of convergence were measured in 100 office workers ...
