Dummy eye measurements of microsaccades: testing the influence of system noise and head movements on microsaccade detection in a popular video-based eye tracker [PDF]

open access: yes, 2015
Whereas early studies of microsaccades have predominantly relied on custom-built eye trackers and manual tagging of microsaccades, more recent work tends to use video-based eye tracking and automated algorithms for microsaccade detection. While data from

Sutureless scleral fixated three-piece intraocular lens in the management of dislocated capsular bag–capsular tension ring–intraocular lens complex

open access: yesJournal of Clinical Ophthalmology and Research, 2020
A number of techniques have been described in the management of capsular bag (CB)–capsular tension ring (CTR)-intraocular lens (IOL) dislocation, including pars plana vitrectomy (PPV) with explantation of the CTR and IOL through a corneal section and ...

Longer fixation duration while viewing face images [PDF]

open access: yes, 2006
The spatio-temporal properties of saccadic eye movements can be influenced by the cognitive demand and the characteristics of the observed scene. Probably due to its crucial role in social communication, it is argued that face perception may involve ...

Ultrasound biomicroscopy in the assessment of the intraocular lenses positioning in a transscleral fixation technique [PDF]

open access: yes, 2000
Purpose: To assess, through ultrasound biomicroscopy (UBM), the positioning of the intraocular lenses (IOL) haptics as related to the ciliary sulcus by using a scleral fixation technique; and to evaluate, as well, if two fixation points are sufficient to

Imaging of the Lamina Cribrosa using Swept-Source Optical Coherence Tomography. [PDF]

open access: yes, 2012
The lamina cribrosa (LC) is the presumed site of axonal injury in glaucoma. Its deformation has been suggested to contribute to optic neuropathy by impeding axoplasmic flow within the optic nerve fibers, leading to apoptosis of retinal ganglion cells. To

Scleral-fixated intraocular lenses

open access: yesTNOA Journal of Ophthalmic Science and Research, 2018
Scleral-fixated intraocular lenses (SFIOLs) are important tools for an ophthalmologist when dealing with the eyes that have inadequate capsular support. Since the time of its introduction, SFIOLs and techniques for their implantation have seen many innovations. Initially, sutured SFIOLs were widely performed.
