Of 442 patients with syndromic craniosynostosis, complete ophthalmologic records were available for 253. Although no instances of optic nerve atrophy were noted among those with Saethre-Chotzen or Mue...
A substantial percentage of children with Apert, Crouzon, and Pfeiffer syndromes were found to develop optic nerve atrophy, with a prevalence likely to trend higher with longer follow-up. Chiari malfo...
Risk, III....
Posterior cortical atrophy (PCA) is a progressive neurologic syndrome that presents with complex visual deficits. Although PCA is most commonly a form of Alzheimer disease (AD), its early diagnosis is...
To identify neurobehavioral screening tasks for PCA-beyond simple visual constructions-that can be administered in clinic or at bedside....
We compared the performance of 12 individuals who met neuroimaging-supported consensus criteria for PCA with that of 12 matched individuals with typical AD (tAD) and 24 healthy controls (HC) on clinic...
All of the individuals with PCA were impaired on the figure-ground discrimination task compared with half of the tAD group and no HC. Approximately half of the PCA group had Balint syndrome, dressing ...
The figure-ground discrimination task can be used successfully as an overall screening measure for PCA, followed by specific tasks for Balint syndrome and dressing and limb apraxia. Findings reinforce...
To present electroretinogram findings in extensive macular atrophy with pseudodrusen (EMAP) and describe associated systemic factors....
Retrospective case series....
Data on medical history, visual symptoms, multimodal imaging findings, and visual field were collected from the medical records of patients with extensive macular atrophy with pseudodrusen who attende...
Eighteen patients (10 [56%] females, age 49-66 years) were included. Of these, 17 (94%) had a history of rheumatic fever in childhood and/or adolescence, 7 (39%) had cardiovascular disease, 4 (22%) ha...
In this cohort, electrophysiologic evaluation demonstrated diffuse retinal dysfunction affecting all layers of the retina in patients with EMAP. The disease is associated with immune-mediated systemic...
Change in ventricular volume has been suggested as surrogate measure of central brain atrophy (CBA) applicable to the everyday management of multiple sclerosis (MS) patients....
We investigated the contribution of inflammatory activity (including the severity of lesional tissue damage) to CBA....
Fifty patients with relapsing-remitting multiple sclerosis (RRMS) were enrolled. Lesional activity during 4 years of follow-up was analysed using custom-build software, which segmented expanding part ...
During follow-up, ventricles expanded on average by 12.6% ± 13.7% (mean ±...
CBA is almost entirely explained by the combination of the volume and severity of lesional activity. The expansion of chronic lesions plays a central role in this process....
The inositol 1,4,5-triphosphate receptor type 1 (...
