Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

Saccadic reaction time in mirror image sectors across horizontal meridian in eye movement perimetry

Scientific Reports, 2021
In eye movement perimetry (EMP), the saccadic reaction time (SRT) to ‘seen’ visual stimuli are delayed in glaucoma. Evaluating SRT behaviour in hemi-field sectors could refine its clinical implication.

Automatic Segmentation of Exudates in Ocular Images using Ensembles of Aperture Filters and Logistic Regression [PDF]

, 2013
Hard and soft exudates are the main signs of diabetic macular edema (DME). The segmentation of both kinds of exudates generates valuable information not only for the diagnosis of DME, but also for treatment, which helps to avoid vision loss and blindness.

Evaluation of the Efficacy and Safety of Satralizumab in a Pregnant NMOSD Patient With AQP4/MOG‐IgG Dual Seropositive: A Case Report

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Neuromyelitis Optica Spectrum Disorder (NMOSD) is a chronic autoimmune neuroinflammatory disease, typically characterized by antibodies against aquaporin 4 (AQP4‐IgG) or myelin oligodendrocyte glycoprotein (MOG‐IgG). Simultaneous seropositivity for both antibodies in a single patient is exceedingly rare.

Multidisciplinary Treatment to Restore Vision in Ocular Burns

Journal of Burn Care & Research, 2019
Abstract Periorbital burns generate contraction and distortion of periorbital soft tissue, causing eyelid malfunction, further contributing to loss of vision from corneal scarring or perforation. We present our multidisciplinary algorithm to restore vision in patients with burn-related bilateral corneal blindness with light perception ...

Rare diseases leading to childhood Glaucoma. epidemiology, pathophysiogenesis, and management [PDF]

, 2015
Noteworthy heterogeneity exists in the rare diseases associated with childhood glaucoma. Primary congenital glaucoma is mostly sporadic; however, 10% to 40% of cases are familial. CYP1B1 gene mutations seem to account for 87% of familial cases and 27% of
