The variability of corneal and anterior segment parameters in keratoconus [PDF]

, 2016
Purpose: To analyse, describe and test diverse corneal and anterior segment parameters in normal and keratoconic eyes to better understand the geometry of the keratoconic cornea. Method: 44 eyes from 44 keratoconic patients and 44 eyes from 44 healthy

Cascade reaction triggering and photothermal AuNPs@MIL MOFs doped intraocular lens for enhanced posterior capsular opacification prevention

Journal of Nanobiotechnology, 2023
Posterior capsular opacification (PCO) is the most common complication after cataract surgery. Present strategies can’t meet the clinical needs of long-term prevention.

Evaluation of interface quality in organ-cultured lamellar corneal transplants [PDF]

, 2012
Background: With increasing numbers of lamellar keratoplasties, eye banks are challenged to deliver precut lamellar donor tissue. In Europe, the most common technique of corneal storage is organ culture which requires a deswelling process before surgical

Impact of Choroidal Melanoma Characteristics on Progression-Free Survival in Patients Undergoing Hypofractionated Stereotactic Photon Radiotherapy

Ophthalmology and Therapy, 2023
Introduction In an effort to replace ultrasonography-based thickness measurements, we investigated whether choroidal melanoma characteristics are related to progression-free survival (PFS) in patients monitored after linear accelerator (LINAC)-based ...

Assessing the Spatial Relationship Between Fixation and Foveal Specializations [PDF]

, 2016
Increased cone photoreceptor density, an avascular zone (FAZ), and the displacement of inner retinal neurons to form a pit are distinct features of the human fovea.

Cell-autonomous action of Slit2 in radial migration of cortical projection neurons

Frontiers in Molecular Neuroscience
Neuronal radial migration is a fundamental process for cortical development, the disruption of which causes neurological and psychiatric dysfunctions. SLIT2 plays diverse functions in brain development and is a well-known axon guidance molecule.

The shift in sensory eye dominance from short-term monocular deprivation exhibits no dependence on test spatial frequency

Eye and Vision, 2022
Background Studies have shown that short-term monocular deprivation induces a shift in sensory eye dominance in favor of the deprived eye. Yet, how short-term monocular deprivation modulates sensory eye dominance across spatial frequency is not clear. To

Herpes simplex keratitis: Challenges in diagnosis and clinical management [PDF]

, 2017
Herpes simplex virus is responsible for numerous ocular diseases, the most common of which is herpetic stromal keratitis. This is a recurrent infection of the cornea that typically begins with a subclinical infection of the cornea that establishes a ...
