Repeatability of push-up and push-down methods in the measure of accommodation amplitude [PDF]

, 2017
La mesura de l’amplitud d’acomodació és una pràctica molt habitual en optometria. La majoria de professionals coincideixen en que els mètodes push-up i push-down són els més utilitzats als exàmens visuals degut al fet que són mètodes ràpids, fàcils i ...

Receptive-field subfields of V2 neurons in macaque monkey are adult-like near birth [PDF]

, 2013
Infant primates can discriminate texture-defined form despite their relatively low visual acuity. The neuronal mechanisms underlying this remarkable visual capacity of infants have not been studied in nonhuman primates.

Subjective and objective measurements of the amplitude of accommodation: Revisiting the existing methods and clinical evaluation of newer techniques

Ophthalmic and Physiological Optics, Volume 45, Issue 3, Page 761-768, May 2025.
Abstract Purpose To evaluate the repeatability and agreement of established and newer methods for measuring the amplitude of accommodation in non‐presbyopic and early presbyopic individuals. Methods The amplitude of accommodation of 81 participants was measured using five different methods (two push‐up techniques, two minus lens techniques and one ...

Comparison Between MEM and Nott Dynamic Retinoscopy

Optometry and Vision Science, 1999
The aim of this study was to compare MEM dynamic retinoscopy with the Nott method, to discover whether there were different results in the accommodative response and whether a relation exists between the two techniques.We performed MEM and Nott dynamic retinoscopy in 50 visually normal university students. Both methods were performed first on the basis

Classification of accommodative insufficiency by monocular subjective push‐up test is poorly predictive of monocular objective amplitudes in children and young adults

Ophthalmic and Physiological Optics, Volume 45, Issue 1, Page 14-22, January 2025.
Abstract Introduction To determine whether classification of accommodative insufficiency (AI) based on the subjective push‐up test is indicative of reduced amplitude measured objectively. Methods Monocular subjective accommodative amplitude was measured in participants 7–24 years of age with the push‐up test; a 0.9 mm letter was moved towards the eye ...
